HP HPE6-A86 Online Questions & Answers

• Question 101:

  HPE Aruba Networking Fabric Composer is being proposed to manage existing HPE Aruba Networking CX switches in a customer environment.

  Which protocol does Fabric Composer use to communicate with the switches?

  A. API
  B. SSH
  C. Telnet
  D. SNMPv3
  A. API

  ---

  Explanation

  HPE Aruba Networking Fabric Composer communicates with CX switches through APIs for automation and orchestration. SSH, Telnet, and SNMPv3 can be management protocols, but they are not the Fabric Composer integration method asked for here.

• Question 102:

  What is a characteristic of a static route?

  A. Must be manually configured
  B. Automatically learned
  C. High processing overhead
  D. Responsive to network changes
  A. Must be manually configured

  ---

  Explanation

  A static route is manually configured by an administrator. It is not automatically learned and does not dynamically adapt to topology changes like a routing protocol. It is useful for simple routing needs with predictable paths.

• Question 103:

  A four-member HPE Aruba Networking CX 6200F VSF configuration is planned to replace the current 5412R switch. The customer has an open-source network management solution.

  How should you respond to their question about monitoring the switches securely?

  A. RMON is a secure way to monitor CX switches.
  B. RESTful API is a secure way to monitor CX switches.
  C. Using a dedicated OOBM port is a secure way to monitor CX switches.
  D. SNMPv2 is a secure way to monitor CX switches.
  B. RESTful API is a secure way to monitor CX switches.

  ---

  Explanation

  The RESTful API can be used as a secure programmatic monitoring and management method for CX switches. SNMPv2 lacks modern security, RMON is not the preferred secure CX monitoring answer, and using an OOBM port is a path choice rather than the secure monitoring protocol itself.

• Question 104:

  What describes the use of the Network Analytics Engine?

  A. Automatically creates tech support diagnostics in the event of a failure
  B. Schedules automated backups of the switch configuration
  C. Automates root cause analytics
  D. Creates support events for the HPE Aruba Networking Support Portal
  C. Automates root cause analytics

  ---

  Explanation

  The Network Analytics Engine is used for automated root cause analytics on AOS-CX switches. It is not primarily a scheduled backup tool, support case generator, or automatic tech-support file creator.

• Question 105:

  When explaining the HPE Aruba Networking Virtual Switching features, which statement about VSF is true?

  A. The switch member ID does not change on either of the members.
  B. The switch control plane is shared.
  C. The configuration is limited to two members.
  D. The management plane operates independently.
  B. The switch control plane is shared.

  ---

  Explanation

  VSF presents multiple physical switches as one logical switch with a shared control plane. It is not limited to only two members in all supported families, and the member management planes do not operate independently in the way separate standalone switches would.

• Question 106:

  You have recently configured a LAG interface between two HPE Aruba Networking CX switches. You have noticed congestion on one of the links and very little traffic on the other.

  Based on the following output, what should you configure to reduce the congestion?

  

  A. Change the hash algorithm.
  B. Change the LACP mode.
  C. Configure a static LAG.
  D. Configure LACP fast rate.
  A. Change the hash algorithm.

  ---

  Explanation

  A LAG can become imbalanced when the selected hashing algorithm maps too many flows onto the same member link. Changing the hash algorithm can distribute traffic more effectively. LACP mode or fast rate affects negotiation and timers, not the traffic distribution calculation.

• Question 107:

  How do you configure an in-band management IP address for the HPE Aruba Networking CX 4100i switch?

  A. interface mgmt ip address 10.10.10.10/24 routing
  B. interface vlan 1 ip address 10.10.10.10/24 routing
  C. interface vlan 1 ip address 10.10.10.10/24
  D. interface mgmt ip address 10.10.10.10/24
  C. interface vlan 1 ip address 10.10.10.10/24

  ---

  Explanation

  An in-band management IP address is configured on a VLAN interface, such as interface vlan 1, with an IP address. The management interface commands apply to out-of-band management, and adding routing to this example is not required for the SVI address statement shown.

• Question 108:

  A technician must identify the neighboring device connected to a switch port without tracing the cable physically.

  Which protocol is designed to advertise neighbor identity and port information?

  A. LLDP
  B. FTP
  C. RSTP
  D. QoS
  A. LLDP

  ---

  Explanation

  LLDP advertises directly connected neighbor identity, capabilities, and port information. FTP transfers files, RSTP prevents Layer 2 loops, and QoS prioritizes traffic, so they do not serve the neighbor-discovery purpose in the question.

• Question 109:

  A customer is about to connect a new HPE Aruba Networking CX 6200 switch using ports 1/1/47 and 1/1/48 to an existing HPE Aruba Networking 5406R switch in a VSF configuration.

  The VSF is already configured with the following settings:

  

  What needs to be configured on the new CX 6200 switch?

  A. interface lag 27 lacp mode enable vlan trunk allowed 50,100,200,300 vlan trunk native untagged 50
  B. interface lag 27 lacp mode enable vlan trunk allowed 50,100,200,300 vlan trunk native tagged 50
  C. interface lag 27 lacp mode active vlan trunk allowed 100,200,300 vlan trunk native 50
  D. interface lag 27 lacp mode active vlan trunk allowed 50,100,200,300 vlan trunk native 50
  C. interface lag 27 lacp mode active vlan trunk allowed 100,200,300 vlan trunk native 50

  ---

  Explanation

  The new CX 6200 configuration must use LACP active mode and allow VLANs 100, 200, and 300 with native VLAN 50. The other choices either use the wrong LACP mode or include native VLAN handling that

  does not match the existing VSF trunk requirements.

• Question 110:

  Refer to the exhibit:

  

  What information is provided based on this output?

  A. The switch does not have management VRF defined for connectivity.
  B. HPE Aruba Networking Central has been manually disabled on the switch.
  C. The switch does not have a valid support contract.
  D. HPE Aruba Networking Central configuration is in the factory default.
  B. HPE Aruba Networking Central has been manually disabled on the switch.

  ---

  Explanation

  The output indicates that the Aruba Central configuration has been manually disabled on the switch. That is different from a missing management VRF, a support-contract problem, or a factory-default Central configuration state.
