The command rollback running-config checkpoint system-fm-pim-best-effort is used to restore the configuration changes made by disabling the PIM feature and skipping any errors. In Cisco Data Center Core Technologies, it’s essential to understand that rollback is a feature that allows administrators to take a snapshot of the configuration before making changes, so they can quickly roll back if needed. The system-fm-pim-best-effort option ensures that the rollback occurs even if there are errors encountered during the process, ensuring that as much of the previous state is restored as possible.

 Creating a virtual iSCSI vNIC (B) is necessary for the server to perform an iSCSI boot from the storage array. This virtual iSCSI vNIC serves as an iSCSI boot firmware table (iBFT) configuration placeholder for iSCSI boot configuration. It is not an actual vNIC but is essential for the iSCSI boot process as it holds the configuration details required for the server to communicate with the storage array during the boot process1.

References: The process of configuring iSCSI boot in Cisco UCS Manager, including the creation of a virtual iSCSI vNIC, is detailed in Cisco’s documentation

The statement that is true about upgrading the firmware on a Cisco MDS storage switch with dual supervisors is that the new firmware is load on the standby supervisor first. This is part of the non-disruptive upgrade process that allows the switch to continue operating while the firmware is updated. The standby supervisor receives the new firmware image and reloads with the new version, while the active supervisor remains in service with the old version. Then, a switchover occurs, making the standby supervisor the new active one, and the old active supervisor receives the new firmware image and reloads. Finally, the modules are upgraded one by one, starting from the lowest numbered module. The other statements are not true because:

• The standby supervisor does not need to be offline before the firmware upgrade begins. It can be online and in standby mode, ready to receive the new firmware image and reload.
• Both supervisors do not load the new firmware and then the active supervisor reboots. This would cause a disruption of service and a loss of configuration. The firmware upgrade is done in a sequential manner, with one supervisor at a time.
• Supervisors cannot be upgraded independently to test the new firmware. The firmware versions on both supervisors must match, otherwise the switchover will fail and the switch will not operate properly.

The series of commands provided in the exhibit are part of the process to update and activate firmware on a Cisco UCS server adapter. The update firmware command is used to update the firmware, while the activate firmware command, combined with the set-startup-only option, schedules the activation of the firmware upon the next reboot of the adapter. This means that the new firmware will not be active immediately but will take effect after the adapter is rebooted, ensuring that the current operations are not disrupted.

References: For further details on firmware management commands and their effects in Cisco Data Center Core Technologies, you can refer to the Cisco UCS Manager Firmware Management Guide, which provides comprehensive instructions on updating and activating firmware on UCS components1. Additionally, the Cisco UCS Manager CLI Configuration Guide offers insights into the CLI commands used for managing firmware

To create a certificate request in Cisco UCS Manager, the correct command set involves navigating to the security scope, selecting the appropriate keyring, and then creating the certificate request with the specified IP address and subject name. The commands in option D correctly follow this procedure. The commit-buffer command is used to commit the changes in UCS-A, which is the primary fabric.

References: This process is documented in the Cisco UCS Manager certificate management guidelines, which provide step-by-step instructions on creating certificate requests using the CLI

Enabling the vPC peer gateway feature on the vPC devices allows them to act as the active gateway for packets that are addressed to the router MAC address of the vPC peer. This capability allows both vPC peers to forward traffic and eliminates traffic disruption when one of them goes down, ensuring high availability in network operations.

References: = For more detailed information, you can refer to the Cisco Nexus 9000 Series NX-OS High Availability and Redundancy Guide, which provides guidelines on configuring vPC peer gateway features for enhanced network stability and availability.

To create a VSAN on the network, the engineer needs to select Fabric A from the drop-down menu. This will allow the engineer to assign a VSAN ID and a name to the new VSAN, and to add members to the VSAN. The other options are not relevant for creating a VSAN. Fabric B is the other fabric interconnect, FC Zoning Enabled is a feature that allows traffic isolation within a VSAN, and Common/Global is a default VSAN that cannot be modified. References:

 SSH (Secure Shell) is the protocol that allows secure remote login from one computer to another. It provides strong authentication and secure communications over unsecured channels. This protocol is preferred for automated onboarding of devices like Cisco Nexus 9000 Series Switches because it supports strong encryption and credential-based authentication, which aligns with the requirement for minimal connection methods and security. SSH is commonly used in network automation for secure command execution and file transfers1.

References := For more information on configuring Cisco Nexus 9000 Series Switches for automation and integration with systems like Cisco UCS Director, you can refer to the Cisco Nexus 9000 Series NX-OS Programmability Guide, which details the supported manageability features and advanced automation capabilities, including Power On Auto Provisioning (POAP) and integration with automation frameworks

After creating a keyring and generating a certificate request, the next step is to create a trusted point. This involves downloading the certificate chain from the CA authority, converting it to the required format, and creating a Trust-Point on UCS Manager where the certificate details are pasted

The method that a network engineer must use to upgrade the BIOS firmware of a Cisco UCS standalone C-Series rack-mount server is to use the Cisco host upgrade utility. The Cisco host upgrade utility is a tool that allows the network engineer to upgrade the firmware of various components of the server, such as the BIOS, the CIMC, the RAID controller, and the network adapter. The Cisco host upgrade utility can be downloaded from the Cisco website and run from a bootable USB drive or CD-ROM. The Cisco host upgrade utility provides a graphical user interface that guides the network engineer through the firmware upgrade process, and allows the network engineer to select the firmware versions and the components to be upgraded. References :=

On a Cisco Nexus 7700 Series switch, secured MAC addresses can be removed by either manually deleting the address from the configuration or when the address ages out, which is determined by the age limit set for the interface. The other options do not apply to the deletion of secured MAC addresses.

In the context of Cisco Nexus switches, VRF (Virtual Routing and Forwarding) is used to create multiple virtual routing tables within a single switch. By using the default VRF for the scheduler job, the engineer ensures that the TFTP server, which is reachable in the global routing table, can be accessed without the need for additional VRF configuration. This simplifies the backup process and avoids potential issues with VRF-specific routing that could prevent access to the TFTP server.

The Python code snippet provided imports the json module and loads a JSON file into a variable named var1. Since JSON files inherently represent object data as dictionaries in Python, the resulting data structure is a dictionary. This is evident from the output shown, which displays a dictionary with nested dictionaries and lists, containing keys like ‘bd’, ‘ap’, ‘name’, etc., and corresponding values.

References := The explanation is based on standard Python data structures and JSON file handling as described in Python documentation and typical Python programming resources. JSON objects are represented as dictionaries in Python, which is a fundamental concept in working with JSON data in the language.

Option A and D are the correct steps to implement the solution. Enabling encryption for LDAP ensures information integrity and confidentiality during data transmission between systems. Adding a trusted root LDAP certificate to Cisco Intersight establishes a secure connection by validating the authenticity of the LDAP server. References:

• Cisco Intersight User Guide, Release 1.0 - Configuring Cisco Intersight [Cisco Intersight], Configuring Cisco Intersight, Configuring LDAP Settings

• Setting the RADIUS source interface to be mgmt0 for group RAD1 and VLAN 22 for group RAD2 © ensures that login requests from the console and SSH are sourced from the correct interfaces and reach the appropriate RADIUS server.
• Configuring the authentication login to use group RAD1 for console and group RAD2 for remote access (D) directs the switch to use the specified RADIUS server groups for the respective login methods, aligning with the user’s requirements.

These configurations ensure that management access via console and SSH is authenticated through the designated RADIUS servers as intended. It’s important to apply these settings correctly in the switch’s configuration to achieve the desired access control.

Port security on Cisco MDS 9000 series Switches is a feature that allows administrators to restrict access to the switch ports to specific devices. When port security is enabled, it does not automatically add currently logged-in devices to the device database; they must be added manually. This ensures that only authorized devices can access the network, enhancing the security of the SAN environment.

References: The Cisco MDS 9000 Series Security Configuration Guide provides detailed information on the configuration and behavior of port security, including the requirement for manual addition of devices to the database

 Option D is the correct configuration to enable the Cisco UCS Manager to manage a Cisco UCS C-Series server by using a single cable for management and data traffic. The commands enter the server scope, then the cimc scope, then the mgmt-conn scope with the sideband option, which enables the management connection through the sideband interface. Then, the mgmt-conn-state is set to enabled and the changes are committed to the buffer. References:

 The vHBA policy in Cisco UCS Manager is used to specify the WWPN of the storage array and can be configured for zoning type as single initiator multiple targets. The Fibre Channel adapter policy is used to configure interrupt handling and queues of the vHBA interface, which are essential for SAN connectivity.

References: = For more detailed information, refer to the Cisco UCS Manager GUI Configuration Guide and the Cisco Data Center Core Technologies study materials

To install the “Markdown” package from the Python package manager on a Cisco Nexus 93108 Series Switch, the engineer must ensure that the guest shell has internet access to reach the Python package repository. This is achieved by adding the nameserver configuration to /etc/resolv.conf, which allows the system to resolve domain names into IP addresses. After configuring the nameserver, the engineer must run the command sudo chvrf management pip install Markdown to install the package within the management Virtual Routing and Forwarding (VRF) context, which has access to the internet.

References: = For more information on managing packages in the guest shell of Cisco Nexus switches, refer to the Cisco Nexus 9000 Series NX-OS Programmability Guide.

The command in Option D correctly uses a loop to iterate over the range {1…5}, which represents the first five interfaces. The dohost command is used to send commands to the host Cisco Nexus switch from the Guest Shell. The syntax interface eth1/$x and description Server$x within the loop sets the description for each interface eth1/1 to eth1/5 to “Server1” to “Server5” respectively.

Here’s the command from Option D formatted for clarity:

[guestshell@guestshell ~]$ for x in {1..5}; do

dohost "conf t" ;

interface eth1/$x;

description Server$x;

done

This command will configure the description for each of the first five Ethernet interfaces with the respective server number as part of the description.

To configure HSRP on a Nexus 7000 series switch for VLAN 100 and ensure the router is the active master, you would typically use the hsrp command within the VLAN configuration mode, set the priority higher than the default to make it the preferred active router, and use the preempt command to allow the router to take over as the active router if it has a higher priority.

Reverse Path Forwarding (RPF) is a feature used in IP multicast routing that ensures multicast traffic is sent back to the receiver efficiently and without looping. In the context of a content delivery network (CDN) sending video traffic, when a receiver requests traffic through an IGMP join message, the multicast routing device uses RPF to populate the multicast routing table with the correct source (S) and group (G) information. RPF checks the source of the incoming packet against the multicast routing table and forwards the packet only if it arrives on the interface that leads back to the source. This mechanism prevents traffic loops and ensures that the multicast distribution device sends the required traffic back to the receiver along the most efficient path.

References: The explanation is based on the principles of IP multicast routing as detailed in Cisco’s Data Center Core Technologies documentation, specifically the sections on “Implementing Multicast in Data Center” and “IP Multicast Technology Overview” which discuss the role of RPF in multicast distribution

The correct command to add to the script is option B, which concatenates the string ‘fusion-config_’ with the variable date to form the filename. This will result in a filename that includes the desired prefix followed by the current date, matching the format specified in the question.

References := For more information on scripting and automation within Cisco environments, you can refer to the Cisco Data Center Core Technologies documentation, which includes guidelines on using Python scripts for network configuration and management tasks.

 Terraform is an infrastructure as code (IaC) tool that allows users to define both cloud and on-premises resources in human-readable configuration files that can be versioned, reused, and shared. In the context of Cisco Data Center Core Technologies, Terraform can be used to enforce the desired state of the network by automatically managing, updating, and reverting configurations as needed to maintain consistency. It supports a wide range of Cisco products and can be extended to manage server infrastructure in the future.

References: The Implementing and Operating Cisco Data Center Core Technologies (DCCOR) course provides insights into the essentials of automation and security in data centers, including the use of IaC tools like Terraform for enforcing desired state configuration1. Additionally, the Implementing Automation for Cisco Data Center Solutions (DCAUI) course further explores the implementation of automation solutions, including Terraform, in Cisco data centers2

 To directly connect a Fibre Channel storage array to a Cisco UCS domain, configuring a new VSAN is essential as it creates a separate fabric to isolate the storage traffic. Additionally, creating a Storage Connection Policy is necessary to define how the UCS domain will communicate with the storage array, including zoning and VSAN membership.

A strict CoPP (Control Plane Policing) policy is designed to manage the traffic flow of control plane packets to protect the control plane of routers and switches from being overwhelmed by unnecessary or malicious traffic. When a ping sweep, which involves sending ICMP echo requests to multiple hosts to identify live devices on a network, is performed on a network connected through a switch with a strict CoPP policy, excess ICMP packets can be dropped to prevent them from consuming excessive resources. References: Cisco Data Center Core Technologies source documents or study guide

Option C meets the security hardening requirements for Cisco UCS C-Series servers’ out-of-band management. It ensures that all traffic is encrypted, uses nondefault ports, and provides private administrative sessions, which align with the company’s security policy

When a Cisco Nexus 9000 series switch encounters a startup configuration corruption, the recovery process involves clearing the current configuration, restarting the device, and then restoring the configuration from a previously saved file. The correct sequence is to first clear the configuration to prevent the corrupted startup configuration from loading upon restart. After restarting the device, the previously saved configuration file should be copied to the running configuration. Finally, to ensure the switch starts with the correct configuration in future restarts, the running configuration should be saved to the startup configuration.

References: The recovery process is detailed in the Cisco community documentation, where it outlines the steps for recovering the configuration in UCS by importing the configuration from a previously saved location

When configuring a vHBA template in UCS Manager, you need to specify the WWPN (World Wide Port Name) from a WWPN pool (B) to uniquely identify the port in the fabric, and the Fabric ID (E) to define the path through which the SAN traffic will flow.

The correct configuration to capture traffic only from the server with the IP address of 198.19.1.19/24 is option C. This configuration uses an IP access list to match packets from the specific IP address with a subnet mask of 255.255.255.255, which indicates a single host. The monitor session command is then used to apply this access list to a SPAN session, ensuring that only traffic from the specified server is captured.

To prevent unauthorized changes at the root level and to restrict access up to the organization level, the appropriate action is to assign users to a specific Cisco UCS locale. A locale is a logical grouping that defines the scope of user permissions in Cisco UCS Manager. By assigning users to a locale, their access can be limited to specific organizations or service profiles, preventing them from modifying policies at the root level.

References: Cisco Data Center Certifications guide3.

To ensure that the Cisco Nexus 7000 series switches are the primary devices for LACP, the configuration must use the lacp system-priority command to assign a lower priority value to the switches. This command determines which device is the active partner in an LACP negotiation. The lower the priority value, the higher the preference. In option A, the switches have a priority value of 1, which is the lowest possible value and the highest preference. Therefore, option A is the correct configuration to make the switches the primary devices for LACP.

References := The explanation is based on the official Cisco documentation on Configuring Link Aggregation Control Protocol (LACP) 1, specifically the section on Configuring LACP System Priority.

 Streaming telemetry as a push model in Cisco devices refers to the mechanism where network devices send data in JSON or GPB format to configured endpoints without being requested for such data. This contrasts with traditional pull models where monitoring clients request data from network devices. References: Implementing and Operating Cisco Data Center Core Technologies (DCCOR v1.2)

Cisco DCNM with SAN Insight is the solution that provides detailed information on the status of storage targets, including capacity metrics. SAN Insight is a feature within Cisco DCNM that allows storage administrators to monitor and analyze storage network traffic, helping to identify and resolve issues such as unexpected capacity limits. It would be the appropriate tool for creating and submitting a daily report of the environment showing the status of storage targets with the highest capacities.

 A Cisco All-Flash HyperFlex solution requires two solid state drives (SSDs) for the local storage configuration of the operating system and persistent logging. The SSDs are used to store the hypervisor, the HyperFlex controller VM, and the system logs. The SSDs also provide high performance and reliability for the system operations. The SSDs are configured in a RAID 1 mirror mode, which provides redundancy and fault tolerance. The SSDs are separate from the data storage drives, which are also SSDs in an All-Flash HyperFlex solution. References :=

To configure a single Cisco APIC controller for Cisco ACI fabric for the first time, you need to configure the first Cisco APIC controller (B) and register the switches that are discovered through LLDP (D). The initial configuration of the APIC is crucial as it sets up the controller with the necessary settings to manage the ACI fabric. Registering the switches through LLDP allows the APIC to recognize and manage the fabric switches, which is essential for the ACI fabric to function correctly. References: Cisco’s official documentation on setting up an ACI fabric1, and the Cisco APIC Basic Configuration Guide2.

Ansible meets the requirements as it uses SSH for transport, does not require agent software to be installed on managed systems, and uses YAML for its playbooks, which is a human-readable data serialization standard, making it easy to read and use for people with limited knowledge of scripting languages.

 Changing the default host firmware policy in Cisco UCS Manager affects any service profile that uses the global-default host firmware policy. This is because the global-default host firmware policy serves as a template for service profiles that do not have a specific host firmware policy defined. When changes are made to the default policy, they propagate to all service profiles that reference it, potentially affecting the firmware version and settings across multiple servers.

References: 350-601 DCCOR exam topics2.

 A logical configuration backup is needed to back up user roles and locales from Cisco UCS Manager. This type of backup allows the engineer to replicate settings, including user roles and locales, to a different fabric interconnect. The file can be reviewed before importing it to the target fabric interconnect. References:

• [Cisco UCS Manager Backup and Restore Management Guide, Release 4.0 - Backup and Restore Overview [Cisco UCS Manager]], Backup and Restore Overview, Backup Types

To prevent loops from occurring accidentally on a switch interface designated for host connectivity, the best practice is to enable Spanning Tree Protocol (STP) protections. Option A, which includes the command spanning-tree guard loop, is the correct configuration to apply. This command enables Loop Guard, a feature that prevents alternate or root ports from becoming designated ports due to a failure that leads to a unidirectional link. If a port stops receiving Bridge Protocol Data Units (BPDUs), Loop Guard puts the port into an STP loop-inconsistent state, effectively preventing potential loops.

References := This information is aligned with the best practices for loop prevention as described in Cisco’s Data Center Core Technologies materials. For further details, refer to the study guide or source documents related to STP and its security features within the Cisco Data Center Core Technologies curriculum.

Puppet, an open-source configuration management tool, requires the Open Agent Container (OAC) to run on Cisco NX-OS. The OAC provides a contained environment where third-party agents like Puppet can run without affecting the host NX-OS system.

References: The requirement for OAC when using Puppet in a Cisco NX-OS environment is outlined in the Cisco NX-OS Puppet Configuration Guide, which explains the integration of Puppet with Cisco NX-OS and the necessary components.

 In a Cisco HyperFlex Edge deployment, the witness VM, known as the “Invisible Cloud Witness,” resides within Cisco Intersight. This cloud-based platform eliminates the need for a dedicated witness VM by providing a virtual witness as a service, which simplifies the deployment and ongoing operations of HyperFlex Edge clusters1234.

The command “show install all impact epld bootflash:n9000-epld.6.1.2.13.1.img” is used to display the impact of the EPLD (Electronic Programmable Logic Device) upgrade on the operation of the Cisco Nexus 9000 series switch. This command does not perform the upgrade; instead, it provides a report that shows what the upgrade would affect if it were to be executed. This is useful for planning and ensuring that the upgrade will not disrupt critical services or operations on the switch. References :=

• Cisco Nexus 9000 Series NX-OS Software Upgrade and Downgrade Guide, Chapter: Managing EPLD Images

To monitor and export traffic to a Network Analyzer, particularly ingress traffic from Host-A and all traffic for VLAN 20 from Host-B, the engineer must implement a configuration that captures the specified traffic and directs it to the Network Analyzer tool. The correct configuration will depend on the capabilities of the network devices in use and the specifics of the Network Analyzer’s requirements.

 The configuration must include setting up a SPAN (Switched Port Analyzer) or RSPAN (Remote SPAN) session that mirrors the desired traffic to a port connected to the Network Analyzer. This would involve specifying the source interfaces or VLANs and the destination port for the mirrored traffic. Additionally, the configuration should ensure that the Network Analyzer is capable of receiving and processing the mirrored traffic, which may require additional settings on the Network Analyzer itself.

To meet the requirements of building a lab replica of a Cisco UCS production environment, the file must be exported in XML format using an encrypted method. Option B, Protocol SCP (Secure Copy Protocol), is used for securely transferring computer files between a local and a remote host or between two remote hosts. Option C, Type Full state, ensures that the complete configuration and state are included in the exported file. References:

The src-dst-port load balancing method ensures that frames in the same flow (identified by the source and destination ports) follow the same links in a port channel. This method is effective in environments with Cisco MDS 9000 Series Switches because it maintains the order of frame delivery within a flow, which is crucial for storage traffic. Subsequent flows can use different links, allowing for efficient utilization of the port channel bandwidth. References: Implementing and Operating Cisco Data Center Core Technologies (DCCOR) course materials.

 In Cisco UCS Central, user privileges are managed through roles and locales. When a user moves departments, their access privileges need to be updated to reflect their new role. By creating a new locale for the Admin department and adding the user to this locale, the user’s access privileges are updated to include the Admin department’s data and applications. The old Finance locale should be deleted, or the user should be removed from it, to revoke the previous access privileges1.

 In a Cisco ACI fabric, when implementing a Virtual Machine Manager (VMM) domain, VLANs can be allocated dynamically or statically within a VLAN pool. To incorporate a static VLAN into a dynamic VLAN pool, the correct approach is to add a static VLAN allocation range to the VLAN pool. This allows for the specific VLAN to be reserved and used consistently for certain applications or services, while still maintaining the flexibility of dynamic allocation for other VLANs within the pool.

Cisco Data Center Network Manager (DCNM) is designed to help manage all NX-OS network deployments, which includes LAN fabrics, SAN fabrics, and IP Fabric for Media (IPFM) networking in the data center. DCNM provides prebuilt templates that can be used to customize fabric deployments, allowing for a more streamlined and efficient setup process. These templates include best-practice policy templates for Easy Fabric Mode and support for Python scripting for more complex policy templates, facilitating the customization and automation of fabric deployments.

References: This information is supported by the Cisco Data Center Network Manager 11 Data Sheet, which outlines the features and benefits of DCNM, including the availability of prebuilt templates for fabric customization

 The correct code snippet to ensure that the Cisco NX-OS scheduler runs every day at 3:00 a.m. is “time daily 3:00”. This command configures the scheduler to execute the specified job daily at the given time, without the need for a ‘start’ keyword, which is not required in the syntax for daily repetitive tasks.

References: This explanation is based on the Cisco NX-OS documentation, which provides guidelines on how to schedule tasks using the NX-OS scheduler feature. The documentation is part of the Cisco Data Center Core Technologies study materials.

The location where the engineer can look for the latest core dump file after a Cisco MDS 9000 series storage switch has reloaded unexpectedly is /mnt/core. A core dump file is a file that contains the memory state of the kernel at the time of a system failure. The core dump file can help the engineer or the Cisco technical support to analyze the cause of the problem and to fix it. The core dump file is stored in the /mnt/core directory on the switch, and it can be accessed using the CLI command ‘show cores’ or ‘utils core active list’. The other directories (/mnt/pss, /mnt/logs, and /mnt/recovery) do not contain the core dump file, but they may contain other useful information for troubleshooting, such as process state information, log files, and recovery files.

The FCoE uplink port type is designed to carry Fibre Channel over Ethernet traffic, which is typically used for storage server communication. Configuring port E1/31-32 as FCoE uplinks will ensure that only storage server traffic for VLAN 200 is forwarded, aligning with the requirement to dedicate these ports solely for storage traffic

To configure the Cisco IMC server management NIC for autonegotiation, you should select the shared LOM setting. This setting allows the Cisco IMC to share the LAN on motherboard (LOM) ports with the host operating system and negotiate the speed and duplex settings automatically. The shared LOM setting also provides redundancy and failover capabilities for the Cisco IMC management access. The other settings (Cisco card, dedicated, and shared LOM EXT) do not enable autonegotiation for the Cisco IMC server management NIC.

References: For more details on how to configure the Cisco IMC server management NIC, please refer to the following resources:

• Cisco Integrated Management Controller Configuration Guide
• Cisco Integrated Management Controller (IMC) Data Sheet

 The correct configuration for a unified I/O link that supports both LAN and SAN traffic using a single Ethernet transport is to configure the interface as a trunk port. This allows multiple VLANs (for LAN traffic) and VSANs (for SAN traffic) to coexist on the same physical link. The auto qos trust dscp command ensures that the Quality of Service (QoS) markings are preserved, which is essential for maintaining traffic prioritization across the network.

References: For more detailed information, please refer to the Cisco Data Center Core Technologies study materials and official documentation available on the Cisco website. These resources provide comprehensive guidance on configuring and managing Cisco Nexus and MDS switches in a data center environment.

To facilitate communication between the APIC controller and an OpenStack OpFlex agent, it’s necessary to enable the Infra VLAN on the Attachable Access Entity Profile (AAEP). The AAEP is used in Cisco ACI to group interfaces that share common policies and extending the Infra VLAN to these interfaces allows the OpFlex agent, which is part of the Cisco Application Centric Infrastructure (ACI), to communicate with the APIC controller. This setup is crucial for the OpFlex agent to function correctly, as it relies on the Infra VLAN for communication with the APIC controller1.

The action that must be performed before renumbering a Cisco UCS chassis is to re-acknowledge the chassis. Re-acknowledging the chassis is a process that forces the Cisco UCS Manager to rediscover the chassis and its components, such as the I/O modules, the power supplies, and the fans. Re-acknowledging the chassis is necessary before renumbering the chassis, because it ensures that the Cisco UCS Manager has the latest information about the chassis and its configuration. Re-acknowledging the chassis also allows the network engineer to apply any pending configuration changes or policies to the chassis and its components. Re-acknowledging the chassis can be done from the Cisco UCS Manager GUI or CLI, by selecting the chassis and choosing the Re-Acknowledge option. References :=

The In-Service Software Upgrade (ISSU) process is designed to upgrade the system software with minimal disruption to the network. Nonstop forwarding (NSF) and stateful switchover (SSO) are two features that work together to maintain packet forwarding and switch state information during the ISSU process. NSF allows the router to continue forwarding packets even when the route processor is failing over, while SSO synchronizes state information between redundant route processors to ensure a seamless transition during a failover1.

References := For a deeper understanding of the ISSU process and its associated features, you can refer to Cisco’s official documentation on In-Service Software Upgrade (ISSU), which provides detailed information on how NSF and SSO contribute to a nondisruptive upgrade

The ACI REST API is a programmatic interface that uses REST architecture to interact with the management information tree (MIT) of the Cisco Application Policy Infrastructure Controller (APIC). The API requires authentication for users to access and manipulate the objects in the MIT. The authentication is based on username and password credentials, and the API provides several methods to manage the session authentication. Two of these methods are:

• POST to aaaLogin. This method logs in a user and opens a session. The message body contains an aaa:User object with the name and password attributes, and the response contains a session token and cookie. The session token and cookie are required for subsequent requests to the API, and they have a limited validity period that can be refreshed.
• DELETE to aaaLogout. This method logs out a user and closes a session. The message body contains an aaa:User object with the name attribute, and the response contains a status code indicating the success or failure of the operation. The session token and cookie are invalidated and cannot be used for further requests to the API.

References := The information is based on the Cisco APIC REST API Configuration Guide, which explains the usage and features of the ACI REST API, including the authentication methods89.

 The command set in Option C is the correct configuration for a Fibre Channel port channel on a Cisco Nexus 9000 Series Switch that meets the specified requirements. The commands in this option perform port-channel protocol negotiation with peer ports using the “channel mode active” command, explicitly configure the trunk mode with “switchport trunk mode on,” and allow VSANs from 10 to 20 with “switchport trunk allowed vsan 10-20.”

References: For further details, you would refer to the Cisco Nexus 9000 Series NX-OS SAN Switching Configuration Guide, which provides instructions on configuring Fibre Channel port channels and related settings.

 The command “alert-group Inventory user-def-cmd show logging last 100” is used to configure the Smart Call Home feature to generate an email with the last 100 lines of the log when new hardware is inserted. This command specifies the alert group ‘Inventory’ and the user-defined command to show the last 100 lines of the logging buffer

Ansible is known for its agentless architecture, which means it does not require any software to be installed on the target devices. It can manage the devices using SSH, which is typically available on most Linux servers. This makes it suitable for scenarios where the operations team needs to update configurations across a large number of devices without direct access1.

References := For more information on how Ansible works and its capabilities for network automation, you can refer to the official Ansible documentation and resources available on the Ansible website1. These resources provide detailed guidance on using Ansible for network automation tasks, including configuration updates and management.

NFSv4 uses TCP for reliable transport and IP for network layer protocol. TCP ensures reliable delivery of packets, which is crucial for file systems, while IP is used for routing the data packets to their destination

The command “ldap-server host 10.10.2.2 enable-ssl” is used to configure AAA authentication on an MDS 9000 switch with an LDAP server located at the IP 10.10.2.2. This command ensures that the data sent to the LDAP server is encrypted using SSL, which is a protocol for securing network communication.

References: For more information, refer to the Cisco Data Center Core Technologies (DCCOR) study guide or source documents, specifically the sections covering AAA authentication configuration and LDAP server integration with MDS 9000 switches.

Ansible is an open-source IT automation tool that is easy to set up and does not require an agent to be installed on target devices. It uses a declarative language and can be extended with custom modules written in Python, which aligns well with the IT team’s experience. Ansible’s agentless architecture and support for Python make it an ideal choice for the company’s requirements.

To monitor traffic between leaf switches in a Cisco ACI network and support filtering traffic from a Bridge Domain or VRF, the configuration must allow for specifying the traffic of interest based on tenant, application, and EPG. Option C, filter tenant t1 application app1 epg epg1, meets these requirements by defining a filter that targets traffic from a specific EPG within an application profile in the tenant ‘t1’. This filter can be applied to the monitoring session to capture the relevant traffic.

References := For detailed procedures on implementing monitoring sessions in Cisco ACI, refer to the Cisco Data Center Core Technologies documentation, particularly sections covering ACI traffic monitoring and filtering.

 The commands shown in the exhibit configure Unicast Reverse Path Forwarding (uRPF) in loose mode on the interface Ethernet 2/2. The ip verify unicast source reachable-via rx command enables uRPF to check that the source address of a received packet has a route in the routing table and that the packet has been received from a valid interface that aligns with the routing table. This helps prevent IP spoofing by ensuring that packets are received from the expected interface.

References := This explanation is based on the principles of uRPF as described in Cisco’s security configuration guides and the Implementing and Operating Cisco Data Center Core Technologies (DCCOR) course materials. For more detailed information, please refer to these resources.

The issue with the implementation is that zones are local to the MDS switch, and name service must be used to activate the connection between E ports. In Cisco MDS switches, zoning is enforced at the switch level. Each switch in a fabric can have a different active zone set or none at all. The name server for each switch only contains information about devices that are logged into that specific switch.

 NFS, or Network File System, is a protocol that allows a user on a client computer to access files over a network in a manner similar to how local storage is accessed. NFS uses remote procedure calls (RPC) over TCP/IP for transport4. References := Wikipedia article on Network File System (NFS)4.

 Option D is the correct statement about the Deployment Immediacy for VMM domains associated to EPGs when the APIC EPG Resolution Immediacy is set to “Immediate”. This means that the policy is pushed to the hardware as soon as the leaf switch is booted, regardless of whether there are any VMs in the EPG or not. This ensures that the policy is ready to be enforced as soon as a VM is created or moved into the EPG. References:

• Cisco APIC Basic Configuration Guide, Release 4.2(x) - Configuring VMM Domains [Cisco Application Policy Infrastructure Controller (APIC)], Configuring VMM Domains, Configuring the Deployment Immediacy for VMM Domains

 Configuring an IP helper address on interface VLAN 10 of the management switch is the correct action to meet the requirements. This configuration allows the management switch to forward DHCP requests from the new switches in different VLANs to the DCNM server, which can then use the zero-touch POAP feature to facilitate fabric creation.

 Option A is the correct action that accomplishes the objective. Setting the pinning max-links value to 8 ensures that all host ports are distributed across all eight configured FEX uplinks, providing optimal bandwidth utilization and redundancy. If an uplink fails, this configuration minimizes disruption by automatically redistributing host ports among the remaining active uplinks. References:

Option C meets the security requirements for the Cisco UCS C-Series Server. It disables unencrypted communication by enabling HTTPS, sets the session timeout to 900 seconds (15 minutes), redirects HTTP to HTTPS to divert unencrypted traffic, and changes the SSH port to a nondefault value (2022), which is essential for CLI-based management.

References := For further details on securing Cisco UCS C-Series Servers, refer to the Cisco UCS C-Series Servers Integrated Management Controller CLI Configuration Guide, which provides instructions on configuring service profiles, security settings, and management access.

An advantage of streaming telemetry over SNMP is that it supports periodic push-based subscription messages. Streaming telemetry is a method of collecting and transporting network data from devices to a receiver, such as a collector or a dashboard. Streaming telemetry allows the devices to send data periodically or on-demand, based on a subscription model. The receiver can subscribe to specific data sets or events that it is interested in, and the device will push the data to the receiver as it becomes available. This reduces the overhead and latency of polling the device status using SNMP, and provides more granular and real-time visibility into the network state and performance. References :=

 Option D is the correct choice. Configuring the vPC role priority and enabling the peer-gateway feature are recommended practices for enhancing vPC convergence times. The peer-gateway feature allows for local forwarding of packets without the need to cross the vPC peer link, which can significantly reduce convergence times during primary peer device failures and recoveries. This approach ensures that the vPC system can quickly adapt to changes and maintain traffic flow even in the event of a device failure123.

References: For more detailed information and best practices, you can refer to Cisco’s official documentation and community discussions on vPC convergence and failure scenarios

An advantage of NFS (Network File System) as compared to Fibre Channel is that NFS provides the dynamic allocation of storage capacity. This means that NFS allows the storage space to be allocated and released on demand, depending on the needs of the applications and users. NFS also enables the sharing of files and directories across different servers and clients, simplifying the management and access of data. Fibre Channel, on the other hand, is a protocol that provides high-speed and low-latency communication between storage devices and servers, but it requires fixed and pre-allocated storage capacity, which can lead to underutilization or overprovisioning of resources. Fibre Channel also requires dedicated hardware and cabling, which can increase the cost and complexity of the storage network.

Before upgrading the Cisco NX-OS software on a Cisco MDS switch, it is important to perform some preparatory steps to ensure a smooth and successful upgrade process. Two of these steps are:

• Check the impact of the upgrade using the show install all impact command. This command displays the compatibility and impact matrix for the upgrade, which shows the current and target versions of the software, the modules that will be upgraded, the modules that will be reloaded, and the modules that will be powered down. This information helps to plan the upgrade and minimize the disruption to the network.
• Back up the configuration of the switch using the copy running-config startup-config command. This command saves the current running configuration to the startup configuration file, which is stored in the bootflash memory of the switch. This ensures that the configuration is preserved and can be restored in case of any issues during or after the upgrade.

References := The information is supported by the Cisco MDS 9000 NX-OS Software Upgrade and Downgrade Guide, which provides detailed instructions and guidelines for upgrading the software on a Cisco MDS switch

NX-API Sandbox is a utility that allows the engineer to translate traditional Nexus CLI inputs and generate Python code using XML and JSON message formats. It is available on a Nexus 7700 series switch as a web-based tool that can be accessed from a browser. It provides a graphical interface for entering CLI commands and viewing the corresponding Python code and output. It also allows the engineer to execute the Python code directly on the switch or copy it to a script file. References := [Cisco Nexus 7000 Series NX-OS Programmability Guide]

 Microsegmentation is a feature of ACI that allows granular control of traffic between endpoints based on vCenter VM attributes, such as name, guest OS, or network adapter type. Microsegmentation works by creating a micro-EPG for each VM and applying contracts and policies to the micro-EPGs. When microsegmentation is enabled, ACI performs distributed switching and routing on the ESXi hosts using the Cisco Application Virtual Switch (AVS) or the Cisco Application Virtual Edge (AVE). This allows ACI to enforce policies at the hypervisor level, without requiring any changes to the physical network or the VM configuration. References :=

• Implementing and Operating Cisco Data Center Core Technologies (DCCOR) v1.2, Module 6: Cisco ACI, Lesson 6.3: Cisco ACI Integration
• Cisco ACI Virtualization Guide, Release 4.2(x), Chapter: Configuring Microsegmentation

 The configuration in Option D is a scheduler configuration for creating backup jobs. It specifies a schedule name, job name, and the command to copy configurations to a server in the operations VRF using TFTP protocol. The time start and repeat options are used to schedule two backup jobs per day.

References := This explanation is based on the principles found in the Cisco Data Center Core Technologies documentation, which details the use of scheduler configurations for backup purposes. For more in-depth information, please refer to the Cisco Data Center Core Technologies source book or the official Cisco documentation at Cisco Data Center Virtualization.

DTLS (Datagram Transport Layer Security) is designed to provide security for datagram-based applications by allowing them to communicate in a way that is designed to prevent eavesdropping, tampering, or message forgery. It is suitable for securing JSON encoded telemetry data sent to an external collector1.

The correct command to restore the running configuration on a Cisco Nexus 5000 Series Switch to an existing snapshot called “stable1” is found in Option C. The command rollback checkpoint stable1 best-effort running-config best-effort ensures that the restore procedure will proceed only if no errors occur, which aligns with the requirement stated in the question. The “best-effort” parameter is crucial as it indicates that the rollback should only proceed if it can be completed without any errors.

Cisco UCS Manager supports various types of authentication mechanisms for enhanced security. Option A (local) refers to the use of locally stored user credentials within the UCS Manager for authentication. Option B (LDAP) indicates that UCS Manager can integrate with LDAP (Lightweight Directory Access Protocol) directories for user authentication, allowing centralized management of user credentials. References: Cisco Data Center Core Technologies source documents or study guide

 The correct answer is option C. The fabric binding configuration in option C matches the output required for the Cisco MDS 9000 Series Switch. Fabric binding enhances the security of the SAN fabric by allowing only authorized switches to join the fabric. The configuration includes specifying the switch world wide name (swwn), domain ID, and member world wide node name (nwwn) to ensure that only the specified devices can participate in the fabric.

References: For more information on fabric binding and its configuration, you can refer to the Cisco MDS 9000 Series Fabric Switches Configuration Guide and the Implementing and Operating Cisco Data Center Core Technologies (DCCOR) study materials.

The output indicates that port channel 1 is trunking, which means it is configured to be an Inter-Switch Link (ISL). ISLs are used in Fibre Channel networks to connect switches and maintain the fabric topology. The “port mode is F” in the output also confirms that it’s an ISL, as F-ports are used for Fabric (switch) ports connecting to N-ports on another switch or node.

The ‘Full State’ backup type in Cisco UCS Manager is designed to capture a snapshot of the entire system, which includes all configuration settings, system logs, and the operating system. This comprehensive backup can be used to fully restore the system in the event of a disaster recovery scenario. The ‘Full State’ backup is the only option that provides a complete system snapshot, making it the ideal choice for disaster recovery purposes.

References: The information regarding backup types and their purposes can be found in the Cisco Data Center Core Technologies source book, specifically in the section discussing system maintenance and backups within the Cisco UCS Manager platform.

APM supports ERSPAN. This will be ERSPAN destination. We need source session from switch.

 Configuring Link Group Preference to Port Channel © allows the use of all four interfaces and provides link failure tolerance. This is because port channels can combine multiple physical links into a single logical link that provides high availability through redundancy. If one link in the port channel fails, traffic is automatically redistributed to the remaining links without any disruption to the network12.

References: The configuration of port channels and link group preferences in a Cisco UCS environment is detailed in Cisco’s official documentation and community discussions related to fabric failover and high availability

The command checkpoint file before_maintenance is used to create a checkpoint of the current running configuration with the specified file name. The command rollback running-config file before_maintenance atomic ensures that the rollback of the checkpoint to the running configuration only occurs if there are no errors during the process. This is essential for maintaining the stability of the switch during maintenance operations.

The question involves an engineer configuring a Cisco MDS 9000 Series Switch and noticing that the name server with IP 192.168.10.11 is missing from the configuration. The correct action to complete the configuration is option C, “Enter yes at step 21 to edit the configuration. Add the line dns-server 192.168.10.11.” This step allows the engineer to modify the initial setup process’s outcome by adding the missing DNS server information directly into the configuration before saving it.

 Multipathing iSCSI traffic is a technique to provide redundancy and load balancing for iSCSI connections between a server and a storage device. Multipathing can be achieved by using multiple initiators, multiple targets, or both. However, some design choices are more optimal than others, depending on the network topology and the capabilities of the devices involved. Option C, “dual initiators to a single target with bonded interfaces,” is a recommended design choice because it provides the following benefits:

• It allows the server to use two separate network interface cards (NICs) to connect to the same iSCSI target, which increases the bandwidth and availability of the connection.
• It enables the use of link aggregation or bonding on the target side, which combines multiple physical interfaces into a logical interface that can handle more traffic and tolerate link failures.
• It simplifies the configuration and management of the iSCSI sessions, as there is only one target to deal with, and the multipathing software can handle the path selection and failover.

References := The information is based on the Cisco Data Center Core Technologies (DCCOR) course, which covers the implementation of data center technologies including network, compute, storage network, automation, and security. More details can be found in the course material and official Cisco documentation on iSCSI multipathing

Option A is the correct command set to configure an extra keyring in Cisco UCS Manager. The commands create a keyring named “extra” with a modulus of 4096 bits, which provides a high level of encryption. The commands also generate a self-signed certificate for the keyring, which enables secure authentication when users use the web interface. References:

To enable port security on all Cisco MDS series switches in the fabric and avoid the extensive manual configuration of the switch ports, the network engineer must activate the CFS (Cisco Fabric Services) distribution and enable the auto-learning port security feature on a per-VSAN basis. CFS is a protocol that allows the switches to distribute and synchronize configuration information across the fabric. By activating the CFS distribution for port security, the network engineer can propagate the port security configuration to all the switches in the fabric automatically, without having to configure each switch individually. The auto-learning port security feature allows the switches to learn and store the port security information of the devices that are already logged in and authorized on the ports, and prevent any unauthorized devices from logging in. The auto-learning port security feature can be enabled on a per-VSAN basis, which means that the port security information is specific to each VSAN and does not affect other VSANs. This provides more flexibility and granularity for the port security configuration. References :=

 To discover a new chassis and establish all links from the chassis to the LAN network in a Cisco UCS domain with a vPC setup, the chassis discovery policy action should be set to one link. The Ethernet ports Eth1/1 and Eth1/2 should be configured as uplink Ethernet ports, and the link group preference should be set to Port Channel. This configuration ensures that the new chassis is properly discovered and that the links are correctly established to handle the LAN traffic.

References: The Implementing and Operating Cisco Data Center Core Technologies (DCCOR) course provides detailed instructions on chassis discovery and vPC configuration. For further guidance, Cisco’s official documentation on vPC best practices and configuration examples would be the appropriate references

 In a vPC (Virtual Port Channel) data center interconnect, both vPC peer devices must have the same system MAC address to ensure that remote switches perceive them as a single logical switch. Since the system MAC value on SW1 is 00:23:04:ee:be:20, the same value must be configured on SW3 to maintain consistency in the vPC domain and ensure seamless communication between the two data center fabrics connected through this vPC interconnect.

References: = The explanation can be inferred from Cisco’s official documentation and resources related to configuring and managing vPCs, ensuring that both peer devices in a vPC domain are configured with identical parameters, including the system MAC address.

The command ‘aaa authentication login default fallback error local’ is used to ensure that if RADIUS servers are unreachable, the system will fall back to using the local user database for SSH access to the Cisco MDS 9000 Series Switch.

The statement that is true about the behavior of multiple roles applied to a user on the Cisco MDS 9000 Series Switch is that access to a command takes priority over being denied access to a command. This means that if a user has multiple roles assigned and one of the roles grants access to a command while another role denies access to the same command, the user will be able to execute the command. The access permission overrides the deny permission in case of a conflict. The other statements are not true because:

• Any commands that have conflicting settings between roles are not denied. As explained above, the access permission prevails over the deny permission in case of a conflict.
• The first role assigned does not take precedence over subsequent roles. The order of role assignment does not affect the command authorization. All roles assigned to a user are evaluated together and the most permissive setting is applied.
• The last role assigned does not take precedence over previous roles. The order of role assignment does not affect the command authorization. All roles assigned to a user are evaluated together and the most permissive setting is applied. References: For more information on how to configure and manage roles on the Cisco MDS 9000 Series Switch, please refer to the following resources:

The FCoE Initialization Protocol (FIP) uses a 24-bit FC-MAP and concatenates a 24-bit Fibre Channel ID to create a fabric-provided MAC address. This is part of the FIP’s role in establishing and maintaining the virtual links between an E-Node and the Fibre Channel Forwarder (FCF). The MAC address is essential for the E-Node to participate in FCoE communications within the fabric. The process ensures that each E-Node has a unique address on the Ethernet network, which encapsulates the Fibre Channel frames for transport. References := Cisco MDS 9000 Series FCoE Configuration Guide, Release 9.x

When there is a domain name change, and the Cisco UCS Manager needs to be available over HTTPS, generating a new default key ring certificate from the Cisco UCS Manager (B) is typically the recommended action. This ensures that the HTTPS service has a valid certificate that matches the new domain name.

The ‘all configuration’ backup type in Cisco UCS Manager includes both system and logical configuration settings. This backup type is an XML file that encompasses all system and logical configurations, making it suitable for scenarios where a complete backup of all settings is required

 Enabling the DHCP relay agent on a switch allows it to forward DHCP BOOTREQUEST packets from clients to a DHCP server, even if they are not on the same physical subnet. This is crucial for clients to obtain an IP address and other network configuration parameters from a DHCP server that is not locally present on the subnet.

References: Detailed information on DHCP relay agents can be found in the Cisco Data Center Core Technologies (DCCOR) study guide or source documents, particularly in the chapters discussing DHCP configuration and management in network environments.

Option A, which utilizes the SFTP protocol with a weekly schedule, aligns with the requirements. SFTP ensures encrypted transmission of data, addressing the need for secure backup. A weekly backup schedule is within the 48-hour Recovery Point Objective (RPO), as it guarantees that the most data that could be lost in a disaster is one week’s worth, which is acceptable within the given RPO. The Recovery Time Objective (RTO) of 4 hours is related to the restoration process rather than the backup schedule or protocol, so it is not directly influenced by the choice of Option A.

References := For more detailed information, refer to the Cisco UCS Manager Backup and Restore Guide, which provides guidelines on setting up disaster recovery policies, including backup schedules and transmission security.

• Enable telemetry features on the Cisco Nexus 9000 Series Switch to collect and send real-time data.
• Configure a secure transport mechanism, such as gRPC with TLS encryption, to ensure that the monitoring data is transmitted securely.

 Static ingress replication is a method used in VXLAN environments where the replication of multicast, broadcast, and unknown unicast traffic is manually defined. In the context of Cisco Data Center Core Technologies, Option A implements static ingress replication by explicitly specifying peers for replication using the ingress-replication protocol static command followed by the peer-ip command to define the IP address of the replication peer. This configuration is necessary when multicast routing is not an option in the underlay network.

References := For further details, one would typically refer to Cisco’s official documentation on VXLAN configurations and the Implementing and Operating Cisco Data Center Core Technologies (DCCOR) study materials, which provide in-depth explanations on the setup and management of network overlays including static ingress replication.

The statement that is true about the impact of a rolling EPLD upgrade on a Cisco MDS 9000 Series Switch is that only the modules that are being upgraded are disrupted. A rolling EPLD upgrade is a type of EPLD upgrade that allows the user to upgrade one or more modules in a switch without affecting the rest of the modules. The rolling EPLD upgrade requires a module reload for each module that is being upgraded, which causes a temporary disruption of traffic and services on that module. However, the other modules in the switch continue to operate normally and do not require a reload. The other statements are not true because:

• All modules on the switch are not disrupted. As explained above, only the modules that are being upgraded are disrupted, while the other modules are unaffected by the rolling EPLD upgrade.
• An EPLD upgrade is not nondisruptive. An EPLD upgrade is a process that updates the firmware of the electrical programmable logic devices (EPLDs) that provide hardware functionalities in the switch modules. An EPLD upgrade always involves a module reload, which causes a disruption of traffic and services on that module. However, the disruption can be minimized by using the hitless or non-disruptive EPLD upgrade modes, which preserve the forwarding state and configuration of the module during the reload.
• The upgrade cannot be performed from the standby supervisor module. The EPLD upgrade process requires the supervisor module to be in active mode before it can be upgraded. The standby supervisor module must be switched to active mode manually or automatically before the upgrade can begin. References: For more information on how to perform a rolling EPLD upgrade on a Cisco MDS 9000 Series Switch, please refer to the following resources:

 The configuration that meets the requirements for a media server to distribute streaming videos only to requesting clients, without propagating the video feed through shared trees if there are no requests, and supporting automatic discovery and announcement of RP-set information, is Option C. This option likely includes the use of Protocol Independent Multicast (PIM) in sparse mode, which is suitable for environments where multiple routers need to dynamically discover the Rendezvous Point (RP) for multicast groups. The configuration would also involve commands to enable Auto-RP for the automatic announcement and discovery of RPs.

References: The explanation is based on the principles of multicast routing and PIM operation as described in Cisco Data Center Core Technologies documentation. For more detailed information, the “Implementing and Operating Cisco Data Center Core Technologies (DCCOR v1.2)” course material and the Cisco official documentation on multicast routing would be the appropriate references.

The Cisco UCS Python SDK (D) is a set of Python libraries that provide a method for automating the configuration and management of Cisco Unified Computing System (UCS) hardware. It allows network administrators to write custom scripts or develop applications to manage UCS environments programmatically. In the context of creating a Django self-service portal for VLAN automation, the UCS Python SDK would be used to interact with the UCS Manager’s API, enabling the automation of VLAN creation and other tasks1.

References: The use of the Cisco UCS Python SDK for automating tasks in UCS Manager is discussed in Cisco’s official blogs and community forums, where examples and best practices can be found12. The SDK provides a more direct and tailored approach for UCS automation compared to other tools, making it suitable for integration with custom Django applications.

 To configure an application profile using REST API, the engineer needs to first authenticate with the APIC using the POST method to the aaaLogin URI. This will return a token that can be used for subsequent requests. The error message indicates that the token is missing or expired, so the engineer needs to perform the POST to aaaLogin method again before configuring the application profile. References := [Cisco APIC REST API Configuration Guide]

The configuration snippet in the exhibit shows that VSAN 100 is allowed on interface Ethernet1/12 with the command “switchport trunk allowed vsan 100”. This means option B, “Allow VSAN 100 on interface eth1/12”, is the correct answer. In Cisco Data Center Core Technologies, it’s essential to allow specific VSANs on an interface to enable traffic flow for those VSANs.References: Implementing and Operating Cisco Data Center Core Technologies (DCCOR) - Configuring FCoE

 To install an operating system on a LUN provided by the Fibre Channel storage array, the engineer needs to configure the boot policy to include a SAN Boot Target with a WWPN (World Wide Port Name). This ensures that the server can communicate with the specific LUN on the storage array during the boot process. Additionally, adding Local CD/DVD and SAN Boot in the boot policy provides flexibility for installation sources, ensuring that both local and networked storage options are available during boot. References := Cisco Data Center Core Technologies source documents or study guide

The benefit of adding Cisco HyperFlex Hardware Acceleration Cards to a HyperFlex deployment is increased compression efficiency. These cards are PCIe devices that offload the compression and decompression operations from the CPU, resulting in higher performance and lower latency for most storage workloads. The cards also reduce the CPU utilization and power consumption of the HyperFlex nodes, enabling more resources for other applications. The other options (offline encryption acceleration, increased network throughput, and GPU acceleration) are not benefits of the HyperFlex Hardware Acceleration Cards. References: For more information on the HyperFlex Hardware Acceleration Cards, please refer to the following resources:

In the context of Cisco ACI (Application Centric Infrastructure), TEP (Tunnel Endpoint) addresses are used for encapsulating and forwarding traffic within the fabric. The next hop addresses mentioned in options A and D are indicative of TEP addresses, which are typically assigned to border leaf switches within the ACI fabric. These border leaf switches are responsible for routing traffic between the ACI fabric and external networks.

• Option A is correct because the next hop 10.0.1.14 for the route 172.16.99.0/24 is consistent with the TEP address format used in ACI, suggesting it is the TEP address of a border leaf.
• Option D is also correct as the next hop 10.1.168.95 for the route 172.16.100.0/24 follows the TEP address pattern, indicating it is the TEP address of another border leaf in ACI.

To create an environment variable that can be used by several policies in the Embedded Event Manager, the engineer should use the command N9k2 (config)# event manager environment mailserver ‘’10.10.10.10’’. This command defines a global environment variable named mailserver with the value of 10.10.10.10, which represents the external email server. The environment variable can then be referenced by any policy that needs to use the email server in its actions, such as sending notifications or alerts. The environment variable can also be modified or deleted as needed. The other commands are incorrect because they either use the wrong mode, the wrong keyword, or the wrong syntax. References :=

 Starting a software upgrade on a Cisco Nexus 5000 Series Switch during a zone merge will result in the zone merge process stopping. This is to prevent any conflicts or issues that may arise from performing two significant operations simultaneously.

To ensure that the Cisco Nexus 7000 series switches are the primary devices for LACP, the system priority needs to be configured with lower values indicating higher priority. In this case, setting N7K_A with a system priority of 100 and N7K_B with a system priority of 200 ensures that N7K_A has a higher priority and becomes the primary device for LACP. The system priority is used in the LACP system ID which determines the LACP priority; the lower the value, the higher the priority.

References: The configuration guidelines for LACP on Cisco devices can be found in the Cisco documentation, which explains the role of system priority in determining the primary device in an LACP setup1. Additionally, the Cisco Data Center Core Technologies study materials provide detailed information on configuring LACP and vPC domain parameters.

The configuration commands shown in the exhibit set up TACACS+ on a Cisco Nexus device. The tacacs-server host command with the key argument specifies that the switch should use an encrypted key when communicating with the TACACS+ server. Therefore, the switch will query the TACACS+ server using an encrypted text PAP login. References: Cisco Data Center Core Technologies source documents or study guide123.

In the ERSPAN configuration provided, Host B is connected to Switch A and is configured as the source of the ERSPAN spanned traffic. This is indicated by the configuration on Switch A, which includes the command monitor session 48 type erspan-source, specifying that it is sending ERSPAN traffic to a destination. The destination IP address for this traffic is set to 10.11.11.2, which corresponds to Host A’s interface VLAN12 IP address. Therefore, Host A, connected to Switch B, is the traffic analyzer, receiving the spanned traffic from Host B.

References := The explanation is based on the standard ERSPAN configuration practices where the source switch is configured with a session type of ‘erspan-source’ and the destination switch with ‘erspan-destination’. This information is typically covered in Cisco’s documentation on ERSPAN configurations and the Cisco Data Center Core Technologies (DCCOR) course materials.

Option D is the recommended method to configure the SAN boot when the storage system maps the source WWPN to a unique LUN. This method creates a SAN boot policy in which every initiator is mapped to a different target LUN, which ensures that each server boots from its own LUN and avoids any conflicts or errors. The other options are either incorrect or incomplete for the task. References:

To deploy a Cisco UCS C-Series Server with a single VIC 1455 integrated into a Cisco UCS Manager cluster without fabric extenders, the system should be reset to factory default settings using Cisco IMC. After the reset, VIC ports 1 and 3 should be attached to the Fabric Interconnects. This process ensures that the server is recognized by the UCS Manager and can be managed accordingly. The VIC 1455 supports multiple Ethernet and Fiber Channel over Ethernet speeds, making it suitable for direct connection to Fabric Interconnects1.

 EPLDs (Electronic Programmable Logic Devices) can be upgraded to enhance hardware functionality or resolve known issues without the need for hardware replacement. The upgrade process is disruptive as it requires the module to power down briefly during the upgrade. However, the system performs EPLD upgrades on one module at a time, minimizing the disruption to traffic through only one module at any given time.

 This configuration ensures that if AAA servers cannot be reached, the switch will fall back to using the local user database for authentication when accessing the console. The fallback error local keyword specifies that the local database should be used in case of an error in reaching the AAA servers1.

References := For more information on configuring AAA on Cisco MDS switches, you can refer to Cisco’s official documentation and community discussions which provide insights into setting up authentication methods for different access scenarios1. These resources explain how to configure the switch to handle authentication locally when remote AAA servers are not available.

 To meet the requirements of using the secondary interface and then falling back to the primary interface when it becomes available again, the engineer should enable the Uplink failover option in the vNIC properties of the Cisco UCS Cisco Integrated Management Controller (CIMC) network adapter for a standalone Cisco C-Series server. The Uplink failover option allows the vNIC to switch to the secondary interface in case of a failure in the primary interface, and then switch back to the primary interface when it recovers. The Uplink failover option also allows the engineer to configure the Fallback Timeout value, which determines how long the vNIC waits before switching back to the primary interface. In this case, the Fallback Timeout value is set to 600 seconds, which means the vNIC will wait for 10 minutes before falling back to the primary interface. References :=
