HP HPE6-A86 Online Questions & Answers

• Question 81:

  Which of these is a configurable VLAN on a CX switch?

  A. 4096
  C. 32768
  D. 3311
  D. 3311

  ---

  Explanation

  VLAN IDs are configurable in the valid normal VLAN range, and 3311 falls within that range. VLAN 0 and 4096 are reserved or invalid for normal VLAN creation, and 32768 is outside the standard VLAN ID range.

• Question 82:

  Refer to the diagram below.

  

  After a recent network change, the helpdesk reports that some users could not connect to the print server, Server-1, which is in VLAN 20.

  After further investigation, you find that only devices directly connected to Access-2 are affected.

  Which part of the network should you investigate?

  A. The configured VLAN on Access-2 port 1/1/4.
  B. The link status of Access-2 port 1/1/28.
  C. Subnet mask on clients connected to Access-2.
  D. Allowed VLANs between access switches.
  D. Allowed VLANs between access switches.

  ---

  Explanation

  Only devices connected through Access-2 are affected when reaching a server in VLAN 20, so the inter- switch VLAN allowance is the likely area to inspect. If VLAN 20 is not allowed across the access-switch

  path, affected users cannot reach that VLAN even though local access ports may be up.

• Question 83:

  Which user group exists by default on an HPE Aruba Networking CX 8400 Series switch?

  A. operators
  B. helpdesk
  C. servicedesk
  D. support
  A. operators

  ---

  Explanation

  The operators group is a default user group on the CX 8400 series. The other names listed are not the default group expected by this platform-specific question.

• Question 84:

  A retail store chain customer is replacing 1,496 AOS-S switches with HPE Aruba Networking CX 6000 switches.

  The customer is interested in using ZTP to provision the new switches.

  However, they are concerned about when the switch starts the ZTP process and whether ZTP may change configurations on switches that are already deployed.

  What would address this concern?

  A. If the ZTP operation detects that the DHCP option provided by the TFTP server already has the switch serial number assigned as a configuration file, the ZTP operation ends.
  B. If the ZTP operation detects that the switch has already been added to HPE Aruba Networking Central, the ZTP operation ends.
  C. If the ZTP operation detects that ztp force-provisioning is set, software and configuration are automatically deployed, and the ZTP operation starts.
  D. If the ZTP operation detects that the switch configuration is different from the factory-default configuration, the ZTP operation ends.
  D. If the ZTP operation detects that the switch configuration is different from the factory-default configuration, the ZTP operation ends.

  ---

  Explanation

  ZTP is intended for factory-default devices. If the switch detects that its configuration is no longer factory default, the ZTP process stops so it does not overwrite an already deployed device. This prevents unintended reprovisioning in production.

• Question 85:

  An HPE Aruba Networking CX switch interface has a connected cable, but the port remains administratively disabled after default setup.

  Which command action is normally required on the interface?

  A. Issue no shutdown.
  B. Issue clear arp.
  C. Issue show system.
  D. Issue write memory only.
  A. Issue no shutdown.

  ---

  Explanation

  The no shutdown command administratively enables the switch interface. Clearing ARP does not alter port state, show system only displays platform information, and saving configuration alone does not bring a disabled port online.

• Question 86:

  Which commands can ensure the current configuration persists after a reboot? Choose two.

  A. commit confirm
  B. write memory
  C. save force
  D. copy startup-config running-config
  E. copy running-config startup-config
  B. write memory
  E. copy running-config startup-config

  ---

  Explanation

  write memory and copy running-config startup-config save the current running configuration so it persists after reboot. copy startup-config running-config moves in the opposite direction, and commit confirm or save force are not the standard AOS-CX persistence commands listed here.

• Question 87:

  The customer plans to roll out new HPE Aruba Networking CX 6000 and CX 6100 switches to replace existing AOS-S switches. To make the deployment include fewer manual tasks, the customer has asked how Zero Touch Provisioning, or ZTP, would help with the transition.

  Which statement about ZTP is correct?

  A. ZTP deployment is enabled by default on the management interface.
  B. An SFTP server must be set up for the switch to download the initial configuration.
  C. ZTP connects to HPE Aruba Networking Central and downloads the template configuration over SCP.
  D. A DHCP server must be configured with the required options.
  D. A DHCP server must be configured with the required options.

  ---

  Explanation

  ZTP depends on network bootstrap information, commonly delivered through DHCP options, so the switch can locate provisioning information. It is not an SCP-only Central workflow, and an SFTP server alone is not enough without the required bootstrap information.

• Question 88:

  What is considered a secure protocol?

  A. HTTP
  B. TFTP
  C. Telnet
  D. SNMPv3
  D. SNMPv3

  ---

  Explanation

  SNMPv3 is the secure SNMP version because it can provide authentication and privacy for management traffic. HTTP, TFTP, and Telnet are clear-text protocols and should not be treated as secure management choices.

• Question 89:

  Which command is appropriate when an administrator needs to verify the switch make, model, and serial number from the CLI?

  A. show system
  B. show arp
  C. show vlan summary
  D. show spanning-tree
  A. show system

  ---

  Explanation

  show system is the appropriate command for displaying switch identity details such as make, model, and serial number. ARP, VLAN, and spanning tree commands report forwarding or Layer 2 state rather than overall system identity.

• Question 90:

  Why would a device perform an ARP request?

  A. To find the source IP address for a specific MAC address.
  B. To find the destination MAC address for a specific IP address.
  C. To find the source MAC address for a specific IP address.
  D. To find the IP address for a specific MAC address.
  B. To find the destination MAC address for a specific IP address.

  ---

  Explanation

  ARP is used when a device knows the destination IP address but needs the destination MAC address for local Ethernet delivery. It does not discover a source address, and it does not map a MAC address back to an IP address in this normal forwarding case.
