An administrator implements clustering on Aruba Mobility Controllers (MCs) that run ArubaOS 8.x. An AP is connected to a cluster member. The administrator accidentally powers off the AP.
How does the AP determine that it should failover to an alternate controller in the cluster?

Refer to the exhibit.

An administrator configures a policy for an AP Group. Port 3 of a RAP is a trunk that connects to a switch at a branch office. VLAN 1 is untagged and VLANs 10 (for data) and 11 (for voice) are tagged. The administrator applies an ACL inbound on Port 3 of the RAP.
How does this configuration affect traffic on Port 3?

An administrator adds local administrative accounts to manage the Aruba Mobility Controllers (MCs). Which role should the administrator assign to an administrator who should havethe same privileges as the default admin account?

Refer to the exhibit.

An administrator wants to centralize administrative access to the Aruba Mobility Controllers (MC) and Mobility Master (MM). ClearPass is set up and the preferred authentication protocols is TACACS+. Where should the administrator perform this configuration in the MM hierarchy shown in the exhibit?

An administrator defines credentials in the Mobility Master> Configuration> System section to configure a Mobility Master (MM). The administrator then accesses AirWave and adds the MM in Monitor-Only mode.
The administrator expects AirWave to automatically discover the Aruba Virtual Mobility Controllers (VMCs) also managed by the MM, but does not see these under APs/Devices> New section in AirWave.
What should the administrator do to solve this problem?
