HP HPE6-A86 Online Questions & Answers

• Question 51:

  You are about to start the initial configuration of an HPE Aruba Networking CX 6200M switch.

  How would you connect to the switch to configure the SVI static IP address?

  A. Connect using the RJ-45 console port.
  B. Connect using the Aruba Discovery mobile app.
  C. Connect using the RJ-45 management port.
  D. Connect using the Bluetooth adapter.
  A. Connect using the RJ-45 console port.

  ---

  Explanation

  Initial configuration of a switch SVI static IP address is typically performed through the console when network connectivity has not yet been established. The management port, Bluetooth app, or discovery app can be useful in other workflows, but the RJ-45 console port is the direct setup method here.

• Question 52:

  In the partial example of the LLDP output below:

  What can be validated based on the provided output?

  A. Peer device native VLAN has no name.
  B. Peer device is connected over a Gigabit transceiver.
  C. Peer device port is 1/1/25.
  D. Peer device native VLAN ID is 1.
  D. Peer device native VLAN ID is 1.

  ---

  Explanation

  The LLDP neighbor information validates that the peer's native VLAN ID is 1. LLDP is used to learn details advertised by the directly connected device, including VLAN-related TLVs, so the native VLAN ID is the relevant validated item.

• Question 53:

  You are creating a physical connectivity diagram for a network documentation project.

  Which feature will be the most useful to you?

  A. MSTP
  B. LLDP
  C. ZTP
  D. L2TP
  B. LLDP

  ---

  Explanation

  LLDP advertises directly connected neighbor identity, port, and capability information, making it useful for building or validating physical connectivity diagrams. MSTP handles loop prevention, ZTP handles provisioning, and L2TP is not used for neighbor discovery.

• Question 54:

  What does the acronym AAA stand for?

  A. Aruba Authentication Algorithm
  B. Authentication, Authorization, and Accounting
  C. Access Acceptance Attributes
  D. Authorization, Accessibility, and Accountability
  B. Authentication, Authorization, and Accounting

  ---

  Explanation

  AAA stands for Authentication, Authorization, and Accounting. Authentication verifies identity, authorization determines permitted actions, and accounting records activity. The other expansions are not the standard network security meaning of AAA.

• Question 55:

  You are trying to verify that your HPE Aruba Networking CX switch has access to the local DNS server through the out-of-band management interface.

  You have run the following ping command, but there has been no response:

  ping 10.1.50.11

  What would explain this?

  A. The out-of-band management interface only supports connectivity to its local subnet.
  B. You need to specify the mgmt VRF at the end of the ping command.
  C. You need to create an out-of-band management VRF first.
  D. The out-of-band management interface does not support ping.
  B. You need to specify the mgmt VRF at the end of the ping command.

  ---

  Explanation

  The out-of-band management interface belongs to the management VRF. To test reachability through that interface, the ping must specify the mgmt VRF so the correct routing table and source interface are used.

  Creating a new VRF or assuming ping is unsupported is not the right explanation.

• Question 56:

  Which two checks are useful when troubleshooting a workstation that cannot reach its default gateway through an access switch?

  A. Verify the access port is assigned to the expected VLAN.
  B. Check whether the interface is up and free of excessive errors.
  C. Replace SNMP with TFTP for monitoring.
  D. Disable all Layer 2 redundancy protocols on the network.
  A. Verify the access port is assigned to the expected VLAN.
  B. Check whether the interface is up and free of excessive errors.

  ---

  Explanation

  For an access-layer reachability problem, VLAN assignment and interface health are core checks. The wrong VLAN can isolate the host from its gateway, and interface errors can cause packet loss. Changing monitoring protocols or disabling redundancy protocols does not directly solve workstation gateway reachability.

• Question 57:

  What is modulated to transmit data over a multi-mode cable?

  A. Radio
  B. Light
  C. Voltage
  D. Pressure
  B. Light

  ---

  Explanation

  Multi-mode fiber transmits data by modulating light through optical fiber. Radio, voltage, and pressure describe other physical signaling methods and are not the medium used by fiber-optic cabling.

• Question 58:

  You are checking the interface details for a workstation experiencing connectivity issues.

  Based on the output, which statement about the interface is true?

  A. VLAN 90 is 802.1Q tagged.
  B. Jumbo frames are supported.
  C. Input errors have occurred.
  D. PoE has been disabled.
  C. Input errors have occurred.

  ---

  Explanation

  The interface details indicate that input errors have occurred, which is relevant to a workstation connectivity issue. VLAN tagging, jumbo-frame support, and PoE status are different interface characteristics and do not match the error condition identified by the output.

• Question 59:

  You are planning a 40Gbps link between two sites 35 km apart.

  What type of cable will be required?

  A. ZTP
  B. Single-mode fiber
  C. UTP
  D. Multi-mode fiber
  B. Single-mode fiber

  ---

  Explanation

  Single-mode fiber is the correct medium for long-distance optical links such as 35 km. Multi-mode fiber is intended for shorter distances, UTP is copper cabling with much shorter reach, and ZTP is a provisioning process rather than a cable type.

• Question 60:

  Which two protocols are commonly associated with remote management or monitoring of network devices?

  A. SNMP
  B. Telnet
  C. ARP
  D. STP
  A. SNMP
  B. Telnet

  ---

  Explanation

  SNMP is used for network monitoring and management, and Telnet is a remote terminal management protocol. ARP supports local address resolution, and STP is a Layer 2 loop-prevention protocol rather than an administrative access or monitoring protocol.
