HP HPE6-A79 real exam prep : Aruba Certified Mobility Expert Written Exam

Refer to the exhibit.

A network administrator adds a Mobility Controller (MC) in the /mm level and notices that the device does not show up in the managed networks hierarchy. The network administrator accesses the CLI. executes the show switches command, and obtains the output shown in the exhibit.
What is the reason that the MC does not appear as a managed device in the hierarchy?

• A. The network administrator added the device using the wrong Pre-Shared Key (PSK).
• B. The network administrator has not moved the device into a group yet.
• C. The IP address of the MC does not match the one that was defined in the MM.
• D. The digital certificate of the MC is not trusted by the MM.

Refer to the exhibits.


A network administrator deploys User Based Tunneling (UBT) in a corporate network to unify the security policies enforcement. When users authenticate with 802.1X, ClearPass shows Accept results, and sends the Aruba-User-Role attribute as expected. However, the AOS-CX based switch does not seem to build the tunnel to the Mobility Controller (MC) for this user.
Why does the switch fail to run UBT for the user?

• A. The switch has not fully associated to the MC.
• B. The switch is not configured with the port-access role.
• C. The switch is not configured with the gateway-role.
• D. ClearPass is sending the wrong Vendor ID.
• E. ClearPass is sending the wrong VSA type.

A network administrator has updated the ArubaOS code of a standalone Mobility Controller (MC) that is used for User-Based Tunneling (UBT) to a newer early release. Ever since the MC seems to reject PAPI sessions from the switch with the 10.1.10.10 IP address. Also the controller's prompt is now followed by a star mark: "(MC_VA) [mynode] *#" When opening a support ticket, an Aruba TAC engineer asks the administrator to gather the crash logs and if possible replicate UBT connection attempts from the switch while running packet captures of PAPI traffic on the controller and obtain the PCAP files. The administrator has a PC with Wireshark and TFTP server using the 10.0.20.20 IP address.
What commands must the administrator issue to accomplish these requests? (Choose two.)

• A. Option B
• B. Option E
• C. Option D
• D. Option C
• E. Option A

A network administrator has racked up a 7210 Mobility Controller (MC) that will be terminating 200+ Aps on a medium-size branch office. Next, the technician cabled the appliance with 4SPF+ Direct Attached Cables (DACs) distributed between two-member switching stack and powered it up.
What must the administrator do next in the MCs to assure maximum wired bandwidth utilization?

• A. Configure the same MSTP region that the switches have.
• B. Map the four physical ports to port channel 0.
• C. Make all ports trunk interfaces and permit data VLANs.
• D. Manually set 10Gbps speeds on all ports.
• E. Disable spanning tree and allocate unique VLANs to each port.

Users run encrypted Skype for Business traffic with no WMM support over an Aruba Mobility Master (MM) - Mobility Controller (MC) based network. When voice, video, and application sharing traffic arrive at the wired side of the network, all the flows look alike due to the lack of L2 and L3 markings How can the network administrator identify these flows and mark QoS accordingly?

• A. Use a media firewall policy that match these three flows, and use permit and TOS actions with 56, 40, and 34 values for voice, video, and application sharing, respectively Then enable the Skype4Business ALG in the UCC profiles.
• B. Confirm the MM is the Openflow controller of the MCs and Openflow is enabled in VAP and the firewall roles. Then integrate the MM with the Skype4Business SDN API. and enable the Skype4Business ALG in the UCC profiles.
• C. Confirm the MC is the Openflow controller of the MMs and Openflow is enabled in VAP and the firewall roles. Then enable WMM in a VAP profile.
• D. Confirm the MC is the Openflow controller of the MMs and Openflow is enabled in VAP and the firewall roles. Then enable the Skype4Business ALG in the UCC profiles.
