Free and Premium HP HPE6-A86 Dumps Questions Answers

The correct matches are based on how SNMP monitoring works in an HPE Aruba Networking environment. A managed device is the network device being monitored, such as a switch, router, firewall, controller, or access point. HPE Aruba Networking documentation describes SNMP as a protocol used by network management systems to monitor network-attached devices. The SNMP agent is the software function on the managed device that collects local device information and communicates status, statistics, and configuration-related information to the management system. The SNMP manager is the network management system that queries devices, receives information, and may modify supported device parameters. The Management Information Base, or MIB, is the structured database of object identifiers used to represent device status, counters, statistics, and configuration information. HPE Aruba Networking AOS-CX monitoring documentation points administrators to the SNMP/MIB Guide for configuring SNMP so a device can be monitored from a network management system.

The correct answer is A. The CX 6300M VSF stack is the Layer 3 gateway for VLAN 200 clients, so the DHCP relay configuration must be applied to interface vlan 200, the SVI for the client VLAN. The SVI should use an address in the client subnet, such as 192.168.200.1/24, and the remote DHCP server should be defined with the AOS-CX ip helper-address command. HPE Aruba Networking AOS-CX documentation states that ip helper-address < IPV4-ADDR > defines the address of a remote DHCP server or DHCP relay agent and that the DHCP relay agent forwards DHCP client requests to the defined servers. Option B is incorrect because VLAN 1 is not the VLAN 200 client gateway. Options C and D are incorrect because dhcp-relay server is not the correct AOS-CX command shown for configuring IPv4 DHCP relay on the SVI. The correct configuration is ip helper-address 192.168.1.100 under interface vlan 200.

The correct answer is B. The switch does not have enough PoE budget per port. The HPE Aruba Networking 580EX Series access point requires appropriate power to boot and illuminate its LEDs. HPE Aruba Networking documentation states that the 580EX Series supports 802.3bt Class 6 power or AC power. A standard HPE Aruba Networking CX 6000 48G 4SFP switch, such as the R8N86A model, is a non-PoE switch; the PoE-capable version is identified separately as the CX 6000 48G Class 4 PoE 4SFP 740W switch. Even when using a PoE-capable CX 6000 model, Class 4 PoE provides up to 30W per port, while the AP requires 802.3bt Class 6 or AC power for normal operation. Therefore, if the AP has no lights, the most likely cause from the options is insufficient or unavailable PoE power from the switch port. A wrong VLAN, missing STP configuration, or failure to connect to HPE Aruba Networking Central would not normally prevent the AP from receiving power and showing LEDs.

The correct answer is A. On HPE Aruba Networking AOS-CX switches, the out-of-band management interface is configured under interface mgmt. For a static IPv4 address on the management interface, the correct command is ip static, not ip address. HPE Aruba Networking documentation shows the management interface configuration using interface mgmt, then ip static < address/prefix > , followed by default-gateway < gateway-address > when a gateway is required. The default-gateway command assigns the IPv4 or IPv6 default gateway to the management interface, and HPE documentation notes that an IPv4 default gateway can only be configured if a static IPv4 address has been assigned to the management interface. Option B is incorrect because ip address is used on routed interfaces or VLAN interfaces, not the CX management interface command syntax. Option C is incorrect for the same reason and because vrf attach mgmt is not required here. Option D includes unnecessary VRF configuration and the invalid vrf attach mgmt

The correct answer is D. 3311. HPE Aruba Networking AOS-CX documentation identifies valid VLAN IDs as being in the range of 1 to 4094 for VLAN-related configuration, including access VLANs and trunk/native VLANs. Because 3311 falls inside the valid configurable VLAN ID range, it is the only valid option listed. Option A, 4096, is invalid because it is above the supported VLAN ID range. Option B, 0, is invalid because configurable VLAN IDs begin at 1. Option C, 32768, is far outside the supported VLAN ID range and cannot be configured as a VLAN ID on a CX switch. This question tests the standard IEEE 802.1Q VLAN ID range as applied in HPE Aruba Networking CX configuration. The supported configurable VLAN range is 1 through 4094, with VLAN 1 commonly used as the default VLAN and VLAN IDs such as 3311 available for administrator-defined VLANs.

The correct answer is D. As a response to the broadcast DHCP query. DHCP clients initially do not have an IP address, so they commonly use broadcast DHCP discovery/request traffic to locate a DHCP server on the local network. HPE Aruba Networking documentation for DHCP relay explains that when a DHCP client broadcasts a request, the DHCP relay agent on the switch receives the packets and forwards them to the DHCP server as unicast requests. In this scenario, the access points are in VLAN 50, and VLAN 50 also contains DHCP servers. Because the DHCP server is on the same local management VLAN as the APs, the APs can obtain addresses through the normal DHCP broadcast process within that VLAN. Anycast and multicast are not used for the basic DHCP address request in this scenario. A unicast DHCP relay message can occur between a relay agent and a DHCP server when the server is on another subnet, but the client-side DHCP discovery begins as broadcast traffic.

The correct answer is C. auditors. HPE Aruba Networking AOS-CX documentation for the 6200, 6300, and 6400 switch series identifies three built-in user groups: administrators, operators, and auditors. These built-in groups have fixed privileges. The administrators group has full privileges, including full CLI access, firmware upgrades, configuration viewing, configuration changes, and user account management. The operators group has no switch configuration privileges and is mainly limited to basic display-only access and viewing nonsensitive configuration information. The auditors group is restricted to audit-related functions. Since the question asks which user group exists by default on a CX 6400 Series switch, “auditors” is the only listed option that matches the HPE Aruba Networking AOS-CX built-in groups. The other options—read-only, restricted, and reporting—are not listed as default built-in AOS-CX user groups for the CX 6400 platform. This makes option C the verified answer.

The correct answer is A. API. HPE Aruba Networking Fabric Composer is an orchestration and management platform for supported AOS-CX switches. HPE Aruba Networking Fabric Composer documentation describes Fabric Composer as managing and orchestrating HPE Aruba Networking AOS-CX switch fabrics and includes an API Explorer containing Fabric Composer API documentation. The Fabric Composer guide also describes system settings for switch polling, switch events through a web socket connection, and enhanced logging of API calls. This aligns with Fabric Composer using API-based communication and orchestration rather than traditional CLI-only management. SSH can be used for direct administrator access to a switch, but it is not the best answer for Fabric Composer’s switch-management communication method. Telnet is insecure and not appropriate. SNMPv3 is useful for secure monitoring, but it is not the protocol used by Fabric Composer for configuration orchestration of CX switches. Therefore, the correct option is API.

The correct answer is B. 2. The diagram shows two VLANs: VLAN 10 and VLAN 20. In Ethernet switching, each VLAN represents a separate Layer 2 broadcast domain. HPE Aruba Networking documentation defines a VLAN as a single Layer 2 network that can be partitioned to create multiple distinct broadcast domains, isolated from each other unless traffic passes through a router or Layer 3 interface. In this diagram, PCs A and B are in VLAN 10, so they share one broadcast domain. PCs C and D are in VLAN 20, so they share a second broadcast domain. The Layer 3 switch has SVIs for VLAN 10 and VLAN 20, which allow routing between the two VLANs, but the SVIs do not merge the broadcast domains. They provide Layer 3 gateways for each VLAN. Therefore, the number of broadcast domains is based on the number of VLANs shown, not the number of PCs, switch links, or SVIs. Since there are two VLANs, there are two broadcast domains.

The correct answer is A. operators. HPE Aruba Networking AOS-CX documentation for the CX 8400 identifies built-in user groups that exist by default on the switch. These include administrators, operators, and auditors. The operators group has limited privileges, such as basic display-only CLI access and the ability to view nonsensitive switch configuration information. It does not have full switch configuration privileges. The other options—helpdesk, servicedesk, and support—are not listed as built-in default user groups for the CX 8400. Those names could be created manually as custom local user groups in some environments, but they are not default AOS-CX groups. Therefore, from the available choices, the default group is operators.

The correct answer is B. Single-mode fiber. A 35 km connection between two sites is a long-distance optical link, and single-mode fiber is the appropriate cable type for long-haul communication. HPE Aruba Networking transceiver documentation describes single-mode fiber as having a small core size and being suitable for long-haul communication because it transmits light in one mode and suffers less intermodal dispersion than multi-mode fiber. Multi-mode fiber is used for shorter-distance links inside buildings or data centers and is not the correct choice for a 35 km site-to-site connection. UTP copper cabling cannot support a 40Gbps Ethernet connection over 35 km. ZTP is Zero Touch Provisioning, not a cable type. HPE Aruba transceiver guidance also lists long-distance optical transceivers, such as 40 km single-mode fiber options, reinforcing that long-distance high-speed links require SMF rather than MMF or copper. Therefore, for a 40Gbps link between sites 35 km apart, the required cabling is single-mode fiber. ( arubanetworking.hpe.com )

The correct answer is C. The contents of Flash survive when a device reboots or powers down. In HPE Aruba switch operation, the active configuration used by the device while it is running is the running configuration. The startup configuration is the saved configuration that is preserved and used after reboot. HPE Aruba documentation explains that saving the running configuration writes it to the startup configuration file in Flash memory, allowing the configuration to remain after the switch reboots. This confirms that Flash is nonvolatile storage. HPE Aruba AOS-CX documentation also describes eMMC or SSD switch storage as nonvolatile memory used for persistent storage of configurations, files, databases, and scripts. Option A is incorrect because switch Flash storage is not normally expanded by adding extra Flash for configuration storage. Option B is incorrect because the running configuration is held as the active operating configuration, not simply “Flash.” Option D is incorrect because show running-config displays the current running configuration, not the saved startup configuration stored in Flash.

The correct answer is B. Member 2 becomes Conductor. In the shown VSF stack, member 1 is currently the Conductor, member 2 is the Standby, and member 3 is a regular Member. HPE Aruba Networking VSF documentation explains that the Conductor runs the control plane for the VSF stack, while the Standby keeps a synchronized copy of the Conductor’s configuration database. If the Conductor fails or reboots, the Standby takes over the Conductor role to maintain stack operation. Since the output explicitly shows member 2 as the Standby, member 2 is the member expected to become the new Conductor when member 1 reboots. Option A is incorrect because member 2 is already Standby before the reboot. Option C is incorrect because member 3 is only a normal Member and would not take over while a Standby exists. Option D is not the best answer because the immediate role transition asked by the question is the Standby becoming Conductor.

The correct answers are B and E. On HPE Aruba Networking AOS-CX switches, configuration changes are made to the running configuration. To ensure those changes persist after a reboot, the running configuration must be saved to the startup configuration. HPE Aruba Networking documentation states that write memory saves the running configuration to the startup configuration and is an alias of copy running-config startup-config. The copy running-config startup-config command copies the current running configuration into the startup configuration, overwriting the existing startup configuration if one is already present. Option A, commit confirm, is not the AOS-CX command used to save the current running configuration for reboot persistence. Option C, save force, is not the correct AOS-CX command for this task. Option D is the reverse operation; copy startup-config running-config would copy the saved startup configuration into the active running configuration rather than saving current changes for the next reboot. Therefore, the two valid commands are write memory and copy running-config startup-config.

The correct answer is A. CX 6400. The requirement calls for a chassis-based core switch that can scale to a 12U chassis and support 100G speeds toward the aggregation layer. HPE Aruba Networking CX 6400 QuickSpecs identify the CX 6400 as a modular switch family and include the larger CX 6410 chassis option, which is a 10-slot chassis platform. HPE also lists CX 6400 40/100GbE QSFP28 line modules, which provide the required 100G connectivity. This makes CX 6400 the correct fit for a chassis solution that can scale to the requested physical size and provide 100G uplinks. The CX 10000, CX 9300, and CX 8325 are fixed-form-factor platforms, not modular chassis solutions, so they do not match the stated chassis requirement. Therefore, the best initial proposal is the HPE Aruba Networking CX 6400.

The correct matches are 802.3af for 15.4W, 802.3at for 30W, 802.3bt Type 3 for 60W, and 802.3bt Type 4 for 90W. HPE Aruba Networking AOS-CX PoE documentation explains that PoE powered devices are divided into different types and classes according to their power requirements. It identifies Type 1 as supplying a maximum of 15.4W from the power sourcing equipment, which corresponds to IEEE 802.3af. Type 2 supplies a maximum of 30W, which corresponds to IEEE 802.3at. Type 3 supplies a maximum of 60W and Type 4 supplies a maximum of 90W, both under IEEE 802.3bt. These values are important when selecting switch PoE capability for devices such as access points, cameras, sensors, phones, and other powered devices. The switch must have both the per-port PoE capability and enough total PoE power budget to support the connected devices.

The correct answer is A. Root bridge. In a switched infrastructure using Spanning Tree Protocol, the root bridge is the central reference point for calculating the loop-free Layer 2 topology. HPE Aruba Networking AOS-CX documentation explains that device roles, such as root bridge or leaf node, should be planned by adjusting spanning tree instance priority. It also notes that the placement of root bridges is important in a Layer 2 network domain because deterministic root and secondary root bridges provide predictability and protection. Switches calculate their best path toward the root bridge based on spanning tree information such as bridge priority, path cost, and port roles. This calculation determines which ports forward and which ports block to prevent loops. Option B is incorrect because a designated bridge or designated port forwards traffic for a segment but does not define the overall topology reference point. Option C is incorrect because “alternative bridge” is not the entity that defines best path selection. Option D is incorrect because “common bridge” is not the correct STP role.

The correct answer is B. To find the destination MAC address for a specific IP address. ARP, or Address Resolution Protocol, is used on IPv4 Ethernet networks to map a Layer 3 IPv4 address to a Layer 2 MAC address. HPE Aruba Networking AOS-CX documentation states that ARP maps network addresses assigned to devices to physical addresses, and specifically maps IPv4 network addresses to Layer 2 MAC addresses on Ethernet networks. When a host wants to send traffic to another IPv4 device on the same local network, or to its default gateway, it must know the destination MAC address to build the Ethernet frame. If the MAC address is not already in its ARP table, it sends an ARP request asking which device owns the target IP address. Option A is incorrect because ARP is not used to find a source IP address. Option C is incorrect because the device already knows its own source MAC address. Option D describes reverse mapping, which is not the purpose of a normal ARP request.

The correct answer is B. The switch control plane is shared. HPE Aruba Networking documentation explains that Virtual Switching Framework, or VSF, stacks multiple individual switches into a single logical device using standard Ethernet links. Once the VSF stack is formed, the interconnected switches operate as one virtual switch with a single control plane. HPE Aruba documentation also describes VSF as providing a single point of management access with a shared control plane across all stack members. Option A is incorrect because member IDs are part of the VSF configuration and may be assigned or changed during stack setup. Option C is incorrect because VSF is not universally limited to two members; supported stack size depends on the switch family and software support. Option D is incorrect because an independent management plane describes VSX more than VSF. HPE’s VSF-versus-VSX comparison identifies VSF as having a single management plane, while VSX has dual management planes.

The correct answer is D. show system. HPE Aruba Networking AOS-CX documentation describes the show system command as displaying general status information about the system. The official command example includes fields such as Vendor, Product Name, and Chassis Serial Nbr. These fields provide the switch make, model/product name, and serial number directly in the CLI session. Option A is not the best answer because show support-information is intended for collecting broader support and diagnostic information, not the most direct command for viewing the switch identity. Option B is not the normal user command for displaying switch make, model, and serial number. Option C is incorrect because configuration output shows switch configuration, not necessarily the hardware identity information requested. Therefore, the direct command to display make, model, and serial number is show system.

The correct answer is B. Configure an IP helper for the DHCP server. The IoT device is connected to VLAN 100, whose Layer 3 SVI is 10.100.1.1/24. The DHCP server is 10.200.1.51, which is in a different subnet. DHCP clients initially use broadcast messages to discover a DHCP server, and those broadcasts do not cross Layer 3 boundaries by default. HPE Aruba Networking AOS-CX documentation explains that DHCP relay forwards DHCP client requests to configured DHCP servers, and that the ip helper-address command defines the address of a remote DHCP server or relay agent. The documentation also states that IP helper addresses can be configured on Layer 3 interfaces, Layer 3 VLAN interfaces, and LAG interfaces. Therefore, the correct fix is to configure ip helper-address 10.200.1.51 under interface vlan100. Disabling STP is not appropriate and could create Layer 2 loop risk. A static route may be needed for reachability in some designs, but it does not relay DHCP broadcasts. Broadcast-to-unicast conversion is not the required AOS-CX DHCP relay configuration.

The correct answer is C. The wrong subnet mask has been configured. The PC is configured with IP address 10.211.55.151 and subnet mask 255.255.255.0, which is a /24 network. However, the HPE Aruba Networking CX switch SVI for VLAN 55 is configured as 10.211.55.1/25. A /25 mask divides the 10.211.55.0/24 range into two subnets: 10.211.55.0–10.211.55.127 and 10.211.55.128–10.211.55.255. The switch gateway address 10.211.55.1/25 is in the first /25 subnet, while the PC address 10.211.55.151 is in the second /25 subnet. This means the PC and its configured default gateway are not actually in the same subnet from the switch’s perspective. HPE Aruba Networking AOS-CX CLI documentation shows IP addressing on interfaces using prefix-length notation, such as /25, which defines the subnet size. Option A is incorrect because the port is configured with no shutdown and no STP error state is shown. Option B is incorrect because an access port does not require VLAN tagging from the PC. Option D is incorrect because a PC normally uses a default gateway, not a static route, for Internet access.

The correct answer is D. It is available as a cloud solution. HPE Aruba Networking Central is described in official Aruba documentation as a cloud-based management platform for managing AOS-CX infrastructure. It provides centralized functions for provisioning, configuring, monitoring, and troubleshooting AOS-CX switches. This means it is not limited to on-premises deployment. Option A is incorrect because AOS-CX support in Aruba Central is not limited only to templates; Central also supports monitoring, troubleshooting, and UI-based workflows depending on the software version, group type, and deployment model. Option B is also incorrect because monitoring-only mode is one supported option, but it is not the only supported mode. HPE Aruba documentation specifically notes that AOS-CX switches can be added in monitoring-only mode, but also separately documents configuration using templates and UI groups. Therefore, the broad and correct description for a customer conversation is that HPE Aruba Networking Central is available as a cloud management solution for AOS-CX switches.

The correct answer is D. administrators. HPE Aruba Networking AOS-CX documentation for the 4100i, 6000, and 6100 switch series states that, in addition to user-defined local groups, there are three built-in user groups: administrators, operators, and auditors. The documentation also states that the default admin account belongs to the administrators group. This makes administrators the only valid default group among the answer choices. Option A, root, is not listed as a built-in AOS-CX user group. Option B, managers, is not one of the default AOS-CX groups. Option C, super-users, is also not listed as a built-in group. These names may appear in other systems or older platforms, but on HPE Aruba Networking CX 6100 switches, the built-in local user groups are administrators, operators, and auditors. Therefore, the correct default user group from the listed options is administrators.

The correct answer is B. A VLAN range can be created with the syntax vlan 100-110. HPE Aruba Networking AOS-CX documentation defines the VLAN creation command as vlan < VLAN-LIST > . The VLAN list can contain a single VLAN ID or multiple VLAN IDs separated by commas, dashes, or both. The documentation gives examples such as vlan 2-8,10, which creates VLANs 2 through 8 and VLAN 10. Therefore, vlan 100-110 is the correct AOS-CX syntax for creating a range of VLANs. Option A is incorrect because a colon is not the documented range separator for VLAN creation. Options C and D are incorrect because newly created VLANs are enabled by default. HPE Aruba documentation states that the VLAN is enabled by default and that the shutdown command is used to disable a VLAN. Therefore, no additional enable or no shutdown command is required after creating a VLAN.

The correct answer is A. CX 6300. The configuration shown uses OSPFv2 with a process ID, redistribution of connected routes, and a route map. HPE Aruba Networking AOS-CX IP Routing documentation for the CX 6300 and related higher CX platforms includes OSPFv2 routing commands such as router ospf and redistribute connected route-map. The same command documentation shows redistribution into OSPF with a route map as a supported configuration. By contrast, the AOS-CX IP Routing Guide for lower platforms such as the 4100i, 6000, and 6100 includes OSPF command information showing platform support for OSPF on 5420 and 6200, not on the 4100i, 6000, or 6100. Therefore, from the choices provided, the CX 6300 is the switch family that supports creating this OSPF redistribution configuration. The CX 6000 and CX 6100 are access-layer switches and are not the correct choice for this OSPF route redistribution example.

The correct answer is B. You need to specify the mgmt VRF at the end of the ping command. On HPE Aruba Networking CX switches, the out-of-band management interface uses the management VRF. If you issue a normal ping 10.1.50.11 command without specifying the management VRF, the switch attempts to send the ping using the default routing context rather than the out-of-band management interface. HPE Aruba Networking AOS-CX documentation for the ping command shows that the command supports the optional vrf < vrfname > parameter. The AOS-CX diagnostics documentation also specifically lists this as a cause of ping failure: the user intended to ping through the management VRF but forgot to add vrf mgmt to the command. The correct command would therefore be similar to ping 10.1.50.11 vrf mgmt. Option A is incorrect because the management interface can reach routed destinations if the management VRF has the proper route. Option C is incorrect because the management VRF already exists. Option D is incorrect because ping is supported.

The correct answer is B. Suitable for basic Layer 3 networks. HPE Aruba Networking AOS-CX IP Routing documentation describes static routing as a method that can be used when the network topology is simple enough. Static routes are manually configured routes that tell the switch how to reach specific destination networks or where to send default traffic. This makes static routing useful for smaller, stable, or basic Layer 3 environments where the number of routes is limited and the topology does not change frequently. Option A is incorrect because static routing is normally predictable; the administrator explicitly defines the path. Option C is incorrect because static routing does not scale well to large or complex networks, since every required route must be manually maintained. Option D is incorrect because static routing does not automatically adapt to network failures across the whole network like a dynamic routing protocol can. Therefore, static routing is best described as suitable for basic Layer 3 networks.

The correct answer is B. PoE is disabled on the interface. If there are no lights on the access point, the first issue to investigate is whether the AP is receiving power. HPE Aruba Networking 550 Series installation documentation identifies Power over Ethernet as a supported power source for the AP, including IEEE 802.3bt or 802.3at PoE. HPE Aruba Networking AOS-CX documentation for the CX 6000/6100 PoE command shows that per-interface power distribution can be enabled with power-over-ethernet and disabled with no power-over-ethernet. If PoE is disabled on the switch interface, the AP will not receive power from the Ethernet cable and therefore may show no LEDs. Option A is incorrect because a missing STP configuration would not prevent the AP from powering on. Option C is incorrect because failure to reach HPE Aruba Networking Central would occur after the AP is powered and network-connected. Option D is also incorrect because a wrong VLAN can prevent management or provisioning, but it would not normally stop the AP LEDs from turning on.
