HPE6-A79 Aruba Certified Mobility Expert Written Exam Questions and Answers

Questions 4

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?

Options:

The network administrator added the device using the wrong Pre-Shared Key (PSK).

The network administrator has not moved the device into a group yet.

The digital certificate of the MC is not trusted by the MM.

The IP address of the MC does not match the one that was defined in the MM.

Questions 5

An organization owns a fully functional multi-controller Aruba network with a Virtual Mobility Master (VMM) in VLAN20. They have asked a network consultant to deploy a redundant MM on a different server. The solution must offer the lowest convergence time and require no human interaction in case of failure.

The servers host other virtual machines and are connected to different switches that implement ACLs to protect them. The organization grants the network consultant access to the servers only, and appoints a network administrator to assist with the deployment.

What must the network administrator do so the network consultant can successfully deploy the solution? (Choose two.)

Options:

Allocate VLAN20 to the second server, and extend it throughout the switches, then reserve one IP address for the second MM and another IP address for its gateway.

B. Allocate VLAN20 to the second server, and permit routing between them, then reserve one IP address for the second MM and another IP address for its gateway.

Configure an ACL entry that permits IP protocol 50, UDP port 500, and multicast IP 224.0.0.18.

Allocate VLAN20 to the second server, and extend it throughout the switches, then reserve one IP address for the second MM and another for the VIP.

Configure an ACL entry that permits UDP 500, TCP 4500, and multicast IP 224.0.0.5.

Questions 7

A company with 535 users deploys an Aruba solution with more than 1000 Aruba APs, two 7220 Mobility Controllers, and a single Mobility Master (MM) virtual appliance at the campus server farm. The MCs run a HA Fast failover group in dual mode and operate at 50% AP capacity.

If there is an MM or MC failure, the network administrator must ensure that the network is fully manageable and the MC load does not exceed 80%.

What can the network administrator do to meet these requirements?

Options:

Place the APs in the same hierarchy level.

Create a cluster with AP load balancing.

Enable oversubscription in the HA group.

Add an MC and an MM in the server farm.

Add an MM and enable DC redundancy.

Place the APs in two different AP-Groups.

A network administrator deploys a standalone Mobility Controller (MC) and configures some VAPs within the CAMPUS AP group. The network administrator realizes that none of the VAPs are being broadcasted.

Based on the output shown in the exhibit, what should the network administrator do to solve this problem?
