HP Updated HPE6-A86 Exam Questions and Answers by kiyaan

The correct answer is B. You need to specify the mgmt VRF at the end of the ping command. On HPE Aruba Networking CX switches, the out-of-band management interface uses the management VRF. If you issue a normal ping 10.1.50.11 command without specifying the management VRF, the switch attempts to send the ping using the default routing context rather than the out-of-band management interface. HPE Aruba Networking AOS-CX documentation for the ping command shows that the command supports the optional vrf < vrfname > parameter. The AOS-CX diagnostics documentation also specifically lists this as a cause of ping failure: the user intended to ping through the management VRF but forgot to add vrf mgmt to the command. The correct command would therefore be similar to ping 10.1.50.11 vrf mgmt. Option A is incorrect because the management interface can reach routed destinations if the management VRF has the proper route. Option C is incorrect because the management VRF already exists. Option D is incorrect because ping is supported.

The correct answer is B. PoE is disabled on the interface. If there are no lights on the access point, the first issue to investigate is whether the AP is receiving power. HPE Aruba Networking 550 Series installation documentation identifies Power over Ethernet as a supported power source for the AP, including IEEE 802.3bt or 802.3at PoE. HPE Aruba Networking AOS-CX documentation for the CX 6000/6100 PoE command shows that per-interface power distribution can be enabled with power-over-ethernet and disabled with no power-over-ethernet. If PoE is disabled on the switch interface, the AP will not receive power from the Ethernet cable and therefore may show no LEDs. Option A is incorrect because a missing STP configuration would not prevent the AP from powering on. Option C is incorrect because failure to reach HPE Aruba Networking Central would occur after the AP is powered and network-connected. Option D is also incorrect because a wrong VLAN can prevent management or provisioning, but it would not normally stop the AP LEDs from turning on.

The correct answer is A. SNMP v3. HPE Aruba Networking AOS-CX hardening documentation recommends using SNMPv3 instead of older SNMP versions. Older SNMP versions are unauthenticated and unencrypted, and the community string is transmitted in plaintext. SNMPv3 supports users, authentication, and strong encryption, including stronger authentication and privacy protocols. This makes SNMPv3 the correct version when the requirement is to monitor switches with encrypted SNMP data. Option B and option C are incorrect because SNMPv2 and SNMPv2c do not provide the same authentication and encryption protections required by the question. Option D is incorrect because SNMPv4 is not a valid SNMP version used for this purpose on HPE Aruba Networking CX switches. Therefore, the secure SNMP monitoring choice is SNMPv3.

The correct answer is C. No, SSH and HTTPS are enabled by default. HPE Aruba Networking AOS-CX hardening documentation states that, in the factory-default state, AOS-CX switches have SSH enabled on TCP port 22 and Web UI/read-write REST API enabled on TCP port 443. For the CX 6200 switch series, these services are enabled on both the default and management VRFs. These are secure management protocols because SSH encrypts CLI sessions and HTTPS encrypts web-management sessions. The same HPE Aruba guidance also notes that connections to TCP port 80 are automatically redirected to TCP port 443, which means HTTP is not used as the insecure management method. Option A is incorrect because Telnet is insecure and is not the correct default secure management protocol. Option B is incorrect because Telnet is not the default management method. Option D is incorrect because HTTP connections are redirected to HTTPS. ( arubanetworking.hpe.com )
