Eliminate Risk of Failure with HPE6-A71 Exam Dumps

An administrator mistakenly configures the wrong VLAN setting on a managed controller's interface. This

causes the controller to lose management access to the Mobility Master (MM). The administrator knows that the auto roll-back feature will revert the managed controller to a previous configuration that was used prior to the change.

Which command can the administrator use to validate that the rollback process is successful?

Refer to the exhibit.

An AP is connected to a cluster of controllers. An AAA server provides all authentication and authorization functions for wireless users. A wireless user connects to an AP, and Active User Anchor Controller (A-UAC) and Standby UAC (S-UAC) tunnels are built from the AP to the respective controllers in the cluster.

Why would an administrator create four VRRP groups with four Virtual IP (VIP) addresses in the cluster?

An administrator needs to implement multiple configuration changes on a set of Aruba Mobility Controllers

(MCs) that involve both VLAN and interface configurations at the same time. The controllers are deployed in a cluster.

How can the administrator accomplish this task?

Refer to the exhibit.

An administrator implements an L2 cluster of Aruba Mobility Controllers (MCs) as shown in the exhibit. An external RADIUS AAA server authentication clients associated with the Active User Anchor Controller (A-UAC), where the NAS IP address sent from Controller B is 10.254.1.2.

By default, what happens to the user's session when it is handed over to the Standby UAC (S-UAC) after a failover?

An administrator supports Aruba Mobility Controllers (MCs) managed by a Mobility Master (MM) in a noncluster deployment. The administrator performs these tasks on the MM for the MCs:

Enables L3 IP mobility for the respective VAPs on the MCs

Creates a L3 domain and places the MCs in the domain

However, roaming does not work when users roam from an AP connected to one controller in the domain to an AP connected to a different controller in the domain.

What must the administrator do to fix this problem?
