Anadministrator implements per-user tunneled node that involves ArubaOS-Switches and Aruba Mobility Controllers (MCs). What always happens when a wired client connects to the network?

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?

Anadministrator currently manages an L2 cluster with Aruba Mobility Controllers (MCs) that run ArubaOS
8.x. What happens when the administrator enables AP load balancing?

An administrator implements blacklisting of users that fail authentication functions three or more times.By default, how long will these users have to wait before they can successfully log into the network again?

Refer to the exhibit.

An administrator implements the MultiZone feature. The administrator sets up five zones as shown in the exhibit.
* Zone A has six controllers that form a cluster.
* Zone B has three controllers that form a cluster.
* Zones C, D, and E have a single standalone controller each.
A total of 13 VAPs are created across the five zones. A zone needs to accept RAP connections from branch offices. All zones have the same AP Group name. One of the zones will not accept connections from the MultiZone APs.
What could be a cause of this problem?
