HP HPE6-A86 Online Questions & Answers

• Question 61:

  Which protocols can be used to control administrative access to HPE Aruba Networking AOS-CX switches? Choose two.

  A. RADIUS
  B. LDAP
  C. Diameter
  D. SAML
  E. TACACS
  A. RADIUS
  E. TACACS

  ---

  Explanation

  RADIUS and TACACS are standard AAA protocols used to control administrative access to network devices. LDAP and SAML may be identity technologies in other contexts, and Diameter is not the normal administrative access-control protocol for AOS-CX switch login control.

• Question 62:

  The customer requires the highest speed available using a single-port link between an HPE Aruba Networking CX 6200 and an HPE Aruba Networking CX 8100 over a distance of 3 meters, or 9 feet.

  Which is the correct validated connectivity option for a single port?

  A. 10G-DAC
  B. 100G-DAC
  C. 25G-LR
  D. 50G-DAC
  A. 10G-DAC

  ---

  Explanation

  For the stated CX 6200 to CX 8100 single-port connection over a short 3-meter distance, 10G-DAC is the validated option among the choices. The higher-speed DAC or optical options listed do not match the supported single-port compatibility in this scenario.

• Question 63:

  A new firewall for the default gateway is connected to an HPE Aruba Networking CX 6300 switch. The security administrator has requested that you configure the Layer 3 switch without a bridged port.

  How can this be done on an HPE Aruba Networking switch?

  A. interface 1/1/1 no routing ip address 10.10.10.1/29 no shutdown
  B. interface 1/1/1 routing vlan access 1 ip address 10.10.10.1/29 no shutdown
  C. interface 1/1/1 no routing vlan access 1 ip address 10.10.10.1/29 no shutdown
  D. interface 1/1/1 routing ip address 10.10.10.1/29 no shutdown
  D. interface 1/1/1 routing ip address 10.10.10.1/29 no shutdown

  ---

  Explanation

  A routed physical interface is created with routing enabled on the interface and an IP address assigned directly to it. The no routing and vlan access forms create switched Layer 2 behavior, which is the bridged- port model the question wants to avoid.

• Question 64:

  Which user group exists by default on an HPE Aruba Networking CX 6400 Series switch?

  A. read-only
  B. restricted
  C. auditors
  D. reporting
  C. auditors

  ---

  Explanation

  The auditors group is a default user group on the CX 6400 series. The other listed names are not the expected default group for this platform context, so they should not be selected for the built-in role question.

• Question 65:

  Which firewall port needs to be opened between your Network Monitoring System and HPE Aruba Networking CX switches to collect monitoring data using SNMP?

  A. TCP 162
  B. UDP 1157
  C. TCP 1156
  D. UDP 161
  D. UDP 161

  ---

  Explanation

  SNMP polling and collection normally use UDP port 161 between the network monitoring system and the device agent. UDP 162 is used for traps sent from the device to the manager. The listed TCP ports are not standard SNMP collection ports.

• Question 66:

  Which management option provides cloud-based monitoring and administration for HPE Aruba Networking devices?

  A. Aruba Central
  B. ARP cache
  C. Spanning tree root bridge
  D. VLAN trunk native tag
  A. Aruba Central

  ---

  Explanation

  Aruba Central provides cloud-based monitoring and administration for HPE Aruba Networking devices. An ARP cache, spanning tree root bridge, and VLAN trunk setting are network functions or configuration details, not the cloud management platform.

• Question 67:

  At which layer of the OSI model does HTTP operate?

  A. Session Layer
  B. Network Layer
  C. Application Layer
  D. Data Link Layer
  C. Application Layer

  ---

  Explanation

  HTTP is an application-layer protocol because it defines how applications request and transfer web content. Network and data-link layers handle addressing and framing, while the session layer is not where HTTP itself operates in the OSI model question.

• Question 68:

  You would like to monitor your HPE Aruba Networking CX switches from your existing Network Management System using SNMP and ensure the data is encrypted.

  Which version should you enable on the switches?

  A. SNMP v3
  B. SNMP v2
  C. SNMP v2c
  D. SNMP v4
  A. SNMP v3

  ---

  Explanation

  SNMPv3 should be enabled when encrypted and authenticated SNMP monitoring is required. SNMPv2 and SNMPv2c do not provide the same security protections, and SNMPv4 is not the relevant standard version for this use case.

• Question 69:

  DRAG DROP

  Match the definitions for Power over Ethernet.

  Select and Place:

  

  

  ---

  802.3at = maximum power of 30W;

  802.3bt (Type 4) = maximum power of 90W;

  802.3bt (Type 3) = maximum power of 60W;

  802.3af = maximum power of 15.4W.

  The PoE standards define different maximum power classes. 802.3af is the original lowerpower

  PoE standard, 802.3at increases available power for PoE+, and 802.3bt adds Type 3 and Type 4 classes for higher-power powered devices.

• Question 70:

  Based on the example below:

  

  How is the VSF integrity verified if the VSF links between members 1 and 3, and members 2 and 3, are disconnected?

  A. The peer-switch-based detection will be used.
  B. The VSF has been configured with no split and remains operational on the member.
  C. The management port is used for multi-active detection.
  D. The VSF will detect a split when the topology changes from ring to chain.
  C. The management port is used for multi-active detection.

  ---

  Explanation

  The management port can be used for multi-active detection to help verify VSF integrity when stack links fail. Peer-switch detection and topology-change detection are not the specific integrity mechanism identified in this scenario.
