A company has an Aruba Mobility Master (MM)-based solution. Where can network administrators look to monitor the health status of all controllers, APs, and clients?

Refer to the exhibit.

An Aruba solution uses AirMatch with the default AirMatch profile settings. A network administrator sees that a scheduled optimization was completed, but a plan was not deployed.
Based on the exhibit, why did this occur?

A network manager wants to implement an Aruba wireless solution that accommodates 802.1X with EAP-TLS.
All wireless users will utilize Active Directory (AD) accounts to authenticate.
Which device will the authenticator forward the authentication requests to in this type of solution?

Refer to the exhibit.

The exhibit shows the AAA profile for a WLAN on an Aruba solution. This WLAN uses 802.1X to authenticate users to a RADIUS server. A user successfully authenticates with 802.1X, but the RADIUS server does not send a role assignment.
How does the Aruba firewall handle the role assignment for this user?

Refer to the exhibit.

Network administrators need to set up a WLAN that uses WPA2 encryption and authenticates users with a preshared key (PSK) that is the same for all users. Administrators do not see where they should specify the option for the preshared key.
What should the administrators do?
