HP HPE6-A86 Online Questions & Answers

• Question 1:

  DRAG DROP

  You are troubleshooting a connectivity issue and are reviewing your notes after talking to your team.

  Classify each piece of information as either a symptom or a possible cause. Matches may be used more than once.

  Select and Place:

  

  

  ---

  A new firewall rule has been added = Cause; My email isn't working = Symptom; My device says "No

  Internet" = Symptom; One of the DNS servers is offline = Cause; The switch firmware was upgraded = Cause; Websites aren't loading = Symptom.

  A symptom is an observed user or device problem, while a cause is a condition that can explain the problem. User reports such as broken email, no Internet status, and websites failing to load are symptoms.

  Configuration changes, infrastructure outages, and firmware changes are possible causes to investigate.

• Question 2:

  A customer requires a network upgrade to replace their existing core switches. The new solution must support 100G speeds to the aggregation layer, with the ability to scale to a 12U chassis.

  Which HPE Aruba Networking CX switch model would you initially propose?

  A. CX 6400
  B. CX 10000
  C. CX 9300
  D. CX 8325
  A. CX 6400

  ---

  Explanation

  The CX 6400 is a modular chassis platform that can scale to the chassis size and aggregation requirements in the question. The CX 10000, CX 9300, and CX 8325 choices are fixed or specialized platforms and do not match the stated 12U chassis requirement.

• Question 3:

  Which statement is true when creating VLANs on an HPE Aruba Networking CX switch?

  A. A VLAN range can be created with a syntax of: vlan 100:110
  B. A VLAN range can be created with a syntax of: vlan 100-110
  C. A newly created VLAN needs to be enabled with a command: vlan 100 enable
  D. A newly created VLAN needs to be enabled with a command: vlan 100 no shutdown
  B. A VLAN range can be created with a syntax of: vlan 100-110

  ---

  Explanation

  AOS-CX supports VLAN range creation with hyphen syntax, such as vlan 100-110. Colon syntax is not the expected range form, and newly created VLANs do not require the listed enable or no shutdown commands in this context.

• Question 4:

  You have configured the following on a Core-1 HPE Aruba Networking CX switch for primary and secondary ISP connectivity:

  Core-1(config)# ip route 0.0.0.0/0 10.1.251.2. Core-1(config)# ip route 0.0.0.0/0 10.1.252.2 distance 10.

  The default route via 10.1.251.2 stopped working, and no failover happened.

  The ISP reported a broken fiber on the path of an upstream device. In what condition should the route fail

  over to the 10.1.252.2 router?

  A. When uplink-failure-detection enables the 10.1.252.2 route.
  B. When the BFD session terminates on 10.1.251.2.
  C. When the default route graceful-restart timer expires.
  D. When 10.1.251.2 is no longer in the routing table.
  D. When 10.1.251.2 is no longer in the routing table.

  ---

  Explanation

  A floating static route with a higher administrative distance is used only when the preferred route is removed from the routing table. A remote upstream fiber failure may not remove the next-hop route unless the local route is withdrawn or tracked, so failover occurs when 10.1.251.2 is no longer installed.

• Question 5:

  Which transport protocol is most commonly used for an application that needs ordered delivery, retransmission, and session-oriented communication?

  A. TCP
  B. UDP
  C. ARP
  D. ICMP
  A. TCP

  ---

  Explanation

  TCP provides connection-oriented communication with sequencing, acknowledgments, and retransmission for reliable ordered delivery. UDP is connectionless, while ARP and ICMP are not transport protocols for reliable application sessions.

• Question 6:

  After testing a new HPE Aruba Networking 6200M switch deployment for a small office, you discovered that hosts in different VLANs cannot reach each other.

  What do you need to configure to enable connectivity between VLANs?

  A. Configure an SVI for each VLAN.
  B. Enable IP forwarding on the switch.
  C. Trunk the VLANs to a Layer 2 switch.
  D. Enable inter-VLAN bridging.
  A. Configure an SVI for each VLAN.

  ---

  Explanation

  Inter-VLAN connectivity requires a Layer 3 interface for each VLAN, typically an SVI with an IP address acting as the gateway. Simply trunking VLANs to another Layer 2 switch or enabling a vague bridging function does not provide routing between VLANs.

• Question 7:

  You are trying to configure VSF on a pair of HPE Aruba Networking CX 8100 Series switches.

  What would cause the following error?

  Switch-1(config)# vsf member 2

  Invalid input: vsf

  Switch-1(config)#

  A. VSF ports must be physically connected first.
  B. CX 8100 Series switches do not support VSF.
  C. VSF must be enabled globally on both switches first.
  D. Both switches require a firmware update.
  B. CX 8100 Series switches do not support VSF.

  ---

  Explanation

  The invalid vsf command on CX 8100 indicates that the platform does not support VSF. The problem is not missing physical cabling, a global enable step, or firmware timing; the feature itself is not available on that series.

• Question 8:

  A security auditor asks whether you use any insecure management protocols to configure your HPE Aruba Networking CX 6200 switches from their factory-default state.

  What can you tell them?

  A. No, Telnet and HTTPS are enabled by default.
  B. Yes, Telnet is enabled by default.
  C. No, SSH and HTTPS are enabled by default.
  D. Yes, HTTP is enabled by default.
  C. No, SSH and HTTPS are enabled by default.

  ---

  Explanation

  On CX switches, secure management services such as SSH and HTTPS are enabled by default, while insecure services such as Telnet and HTTP are not the preferred default access methods. This supports basic hardening by avoiding clear-text management protocols.

• Question 9:

  When multiple routes exist to the same destination, which would be installed in the routing table?

  A. Default route
  B. Static route
  C. Lowest administrative distance
  D. Highest administrative distance
  C. Lowest administrative distance

  ---

  Explanation

  When multiple route sources offer a path to the same destination, the route with the lowest administrative distance is preferred for installation in the routing table. A higher administrative distance is less preferred.

• Question 10:

  Which statement is true given the IP address 10.64.0.240 and subnet mask 255.255.254.0?

  A. The network portion of the address is 10.64.
  B. There are more than 8 bits in the host portion.
  C. 10.64.0.240 is a broadcast address.
  D. The prefix length of the network is /25.
  B. There are more than 8 bits in the host portion.

  ---

  Explanation

  The mask 255.255.254.0 is a /23, leaving 9 host bits. Therefore there are more than 8 bits in the host portion. The prefix is not /25, the address is not the broadcast address, and the network portion is longer than only 10.64.
