Where does the Cisco V-Edge Router perform QOS traffic classification?
Ingress interface
Per vEdge
Egress interface
Per VPN
The Cisco V-Edge Router performs QoS traffic classification on the ingress interface, before the traffic enters the VPN. The classification is based on the match criteria specified in the access lists, which can include the source and destination IP addresses, ports, protocols, DSCP values, and application-aware NBAR attributes. The classification results in assigning a forwarding class and a QoS group to each packet. The forwarding class determines the output queue and the scheduling policy for the packet on the egress interface. The QoS group is an internal label that can be used to remark the DSCP value of the packet or to match the packet in another access list for further processing. References:
Which three statements best describe Cisco ISE configuration capabilities? (Choose three.)
Cisco Active Advisor provides additional guidance for ISE deployments.
ISE Deployment Assistant (IDA) is a built in application designed to accelerate the deployment of Cisco Identity Service Engine (ISE)
ISE requires an understanding of the command line for set-up and configuration.
Cisco ISE includes wireless setup wizard and visibility wizard.
ISE wizards and per-canned configurations ease ISE roll-out significantly.
Cisco ISE configuration capabilities include the following features:
The other options, Cisco Active Advisor and ISE command line, are not accurate descriptions of ISE configuration capabilities. Cisco Active Advisor is a separate cloud-based service that provides network health and security checks, device lifecycle management, and best practice recommendations for Cisco devices. It is not directly related to ISE deployments. ISE command line is an interface that allows the user to perform administrative tasks, such as backup and restore, password recovery, and troubleshooting. However, ISE does not require an understanding of the command line for set-up and configuration, as most of the functions can be done through the graphical user interface (GUI).

Which three methods three technologies and deployed to gather data and provide insight? (Choose three.)
BUM traffic
ARP caching
IPv6
Syslog
FNF
SNMP
Syslog, FNF (Flexible NetFlow), and SNMP (Simple Network Management Protocol) are three technologies that can be deployed to gather data and provide insight into the network performance, health, and behavior. Syslog is a standard protocol for logging messages from network devices, such as routers, switches, firewalls, and servers. Syslog messages can be sent to a centralized server for analysis, correlation, and alerting. FNF is a Cisco technology that captures and exports information about network flows, such as source and destination IP addresses, ports, protocols, bytes, packets, and timestamps. FNF can be used to monitor network traffic patterns, identify anomalies, and optimize network resources. SNMP is a protocol that allows network devices to communicate with management systems, such as Cisco DNA Center. SNMP can be used to collect statistics, configuration, and status information from network devices, as well as to send commands and notifications. SNMP can help network administrators to troubleshoot, configure, and manage their network devices remotely.

Whatis a challenge of having an SD-Access Centralized design where a single fabric encompasses the main site and all branch sites across the WAN?
End to End Routing is not supported
DNA Center does not support it.
SSIDs would be the same across all sites
Since the traffic is encapsulated, SD-WAN features can’t be used to optimize/route traffic.
A centralized SD-Access design is where a single fabric domain spans across the main site and all branch sites over the WAN. This design has some challenges, such as:

Which two are benefits from a WAN design? (Choose two.)
Provide lower quality service to guest users
Ensure remote site uptime
Prioritize and secure with granular control
Reduce cost and increase operational complexity
Lower circuit bandwidth requirements
A WAN design is a plan for how to connect multiple sites or locations over a wide area network (WAN). A WAN design can have various benefits, depending on the goals and requirements of the organization. Two of the possible benefits from a WAN design are:
The other options, provide lower quality service to guest users, reduce cost and increase operational complexity, and lower circuit bandwidth requirements, are not benefits from a WAN design. Providing lower quality service to guest users is not a desirable outcome, as it can affect the user experience and the reputation of the organization. Reducing cost and increasing operational complexity is a trade-off that may not be worth it, as it can create more challenges and risks for the network management and maintenance. Lowering circuit bandwidth requirements is not a benefit in itself, but a means to achieve other benefits, such as reducing cost or improving performance. A WAN design should aim to optimize the bandwidth utilization and allocation, rather than simply lowering it.

Which are three Cisco ISE use cases? (Choose three.)
Segmentation
Monitoring
Assurance
Security Incident and Event Management
Access Control
BYOD
Cisco ISE is a network access control solution that uses policy-based decision making to determine if a device is allowed access to the network and, if allowed, what level of access this device is given1.Cisco ISE can also provide authentication, authorization, and accounting (AAA) through the RADIUS protocol and device administration through TACACS+ service1.
Some of the use cases of Cisco ISE are:
Which protocol is used between an Endpoint and a Switch with an 802.1 authentication?
TACACS
EAP
MAB
RADIUS
/configuration/guide/scg3750/sw8021x.pdf
The protocol that is used between an endpoint and a switch with an 802.1 authentication is EAP, which stands for Extensible Authentication Protocol. EAP is a framework that defines how the endpoint (also called the supplicant) and the switch (also called the authenticator) exchange authentication messages over a wired or wireless network. EAP supports various authentication methods, such as passwords, certificates, tokens, or biometrics, and can be encapsulated in different transport protocols, such as RADIUS, Diameter, or EAPOL. EAP is used in 802.1X authentication, which is a standard for port-based network access control that prevents unauthorized access to a network1.
The other options, TACACS, MAB, and RADIUS, are not protocols that are used between an endpoint and a switch with an 802.1 authentication. TACACS is a protocol that provides remote authentication and authorization for network devices, such as routers or switches, but it is not used for endpoint authentication. MAB is a technique that uses the MAC address of an endpoint as a credential for 802.1X authentication, but it is not a protocol itself. RADIUS is a protocol that provides centralized authentication, authorization, and accounting for network access, but it is not used directly between the endpoint and the switch, but rather between the switch and the authentication server1.
