HP HPE6-A86 Online Questions & Answers

• Question 41:

  A customer with stacked switches needs PoE+ ports featured with near-zero downtime, continuous packet forwarding, and highly available hardware.

  Which is correct for an HPE Aruba Networking CX solution?

  A. CX 8100 in VSX
  B. CX 6200F in VSF
  C. CX 8320 in VSX
  D. CX 6300M in VSF
  D. CX 6300M in VSF

  ---

  Explanation

  The CX 6300M with VSF provides stackable access switching with PoE+ and high availability features appropriate for near-zero downtime and continuous forwarding. The other model and feature pairings either use the wrong family or a technology not aligned to this access-stack PoE requirement.

• Question 42:

  A network team wants to combine two physical uplinks between switches so they operate as one logical connection and provide additional resiliency.

  Which technology should be configured?

  A. Link aggregation
  B. Port mirroring
  C. Static routing
  D. Broadcast flooding
  A. Link aggregation

  ---

  Explanation

  Link aggregation combines multiple physical links into one logical connection, improving resiliency and potentially bandwidth. Port mirroring copies traffic for analysis, static routing is Layer 3 forwarding, and broadcast flooding is normal Ethernet behavior rather than an uplink bundle.

• Question 43:

  Based on the example below:

  

  What happens if the VSF link between members 1 and 2 is disconnected?

  A. Member 2 is promoted to Conductor role.
  B. The VSF stack is split and members 2 and 3 remain operational.
  C. The VSF stack is split and member 1 remains operational.
  D. The VSF stack remains fully operational.
  D. The VSF stack remains fully operational.

  ---

  Explanation

  The VSF stack remains operational because the remaining stack connectivity maintains the logical stack. A single disconnected VSF link in a resilient topology does not necessarily split the stack or promote another member to conductor.

• Question 44:

  You are about to log a support case with TAC for an issue with your HPE Aruba Networking CX switch.

  What should you have ready in advance to provide them?

  A. Output of show tech
  B. Generated support keys
  C. SSH access over the Internet
  D. A copy of the running firmware
  A. Output of show tech

  ---

  Explanation

  TAC commonly requests technical support output such as show tech because it collects device state, configuration, and diagnostic details needed for troubleshooting. Internet SSH access, firmware copies, or generated support keys are not the standard first item to prepare.

• Question 45:

  Your manager has asked you to perform basic security hardening on your HPE Aruba Networking CX 6300 switches according to best practices.

  After you have connected the OOBM interface, which configuration tasks should you add to your implementation plan?

  A. Disable SSH and HTTPS in the data plane.
  B. Disable SSH and HTTPS in the management plane.
  C. Enable Telnet and HTTP in the management plane.
  D. Enable SSH and HTTPS in the data plane.
  A. Disable SSH and HTTPS in the data plane.

  ---

  Explanation

  With out-of-band management available, disabling SSH and HTTPS in the data plane is a hardening step that restricts management exposure on production interfaces. Disabling them in the management plane would remove secure management access, and enabling Telnet or HTTP would weaken security.

• Question 46:

  DRAG DROP

  Match the SNMP definitions to the correct term.

  Select and Place:

  

  

  ---

  Collects information and communicates device configuration and status = SNMP agent; gathers and modifies network device parameters = SNMP manager; hierarchical database that stores status, statistics, and configuration information = Management Information Base (MIB); routers, switches, firewalls, wireless controllers, and access points = managed devices.

  An SNMP manager is the monitoring system that queries or sets information. An SNMP agent runs on the managed device and exposes information. The MIB defines the structured object database, and managed devices are the network elements being monitored or controlled.

• Question 47:

  Users report poor performance when uploading files to their document management server in the same subnet. You suspect packet loss is causing the problem.

  Which tool in HPE Aruba Networking Central can you use to confirm this?

  A. Device Check - Cable Test
  B. Network Check - Traceroute
  C. Commands - show interface error-statistics
  D. Network Check - Ping
  C. Commands - show interface error-statistics

  ---

  Explanation

  Interface error statistics are the right evidence when packet loss is suspected on switch ports. Cable test checks physical cable faults, traceroute checks path hops, and ping tests reachability, but error counters directly confirm packet errors on interfaces.

• Question 48:

  A network is configured with two HPE Aruba Networking 2930F switches as the aggregation layer. Each 2930F switch has ten connections. The network has twenty HPE Aruba Networking 2530 access switches connected to both aggregation switches with 1 Gb RJ45 links. Your task is to replace the aggregation switches with HPE Aruba Networking CX 6200 models.

  In this scenario, which configuration would provide redundancy using two ports on the access switches to the aggregation layer?

  A. Create a single VSF domain for the CX 6200 and 2530 switches.
  B. Create VSF on the CX 6200 switches and use stacking with the 2530 switches.
  C. Create a LAG on the 2530 switches to connect to both CX 6200 switches.
  D. Create VSF on the CX 6200 switches and a LAG between the CX 6200 and 2530 switches.
  D. Create VSF on the CX 6200 switches and a LAG between the CX 6200 and 2530 switches.

  ---

  Explanation

  Using VSF on the two CX 6200 aggregation switches lets them operate as one logical aggregation point, and a LAG from each access switch provides redundant uplinks. A single VSF domain cannot include the older access switches, and a LAG to two independent switches would not be valid without the aggregation pair acting as one logical system.

• Question 49:

  A customer has configured an HPE Aruba Networking CX 6200F VSF stack that is already in use. You are given the following information on the setup:

  

  What steps are required to add a new member to the solution?

  A. A link between members 1 and 3 needs to be disconnected.
  B. The topology of the configuration needs to be set to chain.
  C. The VSF link 2 on member 1 must be reconfigured to support new members.
  D. The new member needs to be pre-provisioned as a standby.
  A. A link between members 1 and 3 needs to be disconnected.

  ---

  Explanation

  Adding the new VSF member requires opening the existing link between members 1 and 3 so the new member can be inserted into the stack cabling plan. Changing the topology mode, reworking the wrong VSF link, or pre-provisioning the new unit as standby does not match the required physical insertion step.

• Question 50:

  How can you describe HPE Aruba Networking stacking technologies supported to a new customer focused on another vendor's products?

  A. VSF stacking is supported on CX switches utilizing SFP56 backplane cabling.
  B. VSF stacking supports mixing and matching models with chassis and fixed platforms.
  C. VSF stacking allows existing Provision customers to add members with CX switches.
  D. VSF stacking is supported within the same switch family members.
  D. VSF stacking is supported within the same switch family members.

  ---

  Explanation

  VSF stacking is supported between compatible members in the same switch family. It is not a mix-any-model technology, does not merge legacy Provision and CX members, and is not defined by SFP56 backplane cabling in the way the distractor states.
