Refer to the exhibit.
Client status

A company has an MSM solution that consists of an HP MSM760 Premium Mobility Controller and
HP MSM APs.
Users are having trouble connecting to a VSC with these settings:
Use Controller for Authentication = Enabled
Use Controller for Access Control = Disabled
Security = WPA and WPA2
802.1X authentication = Enabled and local
The exhibit shows the status for one of the user’s clients. The controller system logs RADIUS
failures, however the users never receive messages on their client that state that they have

entered the wrong credentials. The network administrator creates a new account and tiers logging
in with it, and the connection still fails.
Based on this information, what might be the problem?

A.
The controller has lost connectivity with RADIUS servers

B.
The tagging on the APs switch port is incorrect

C.
The controller uses a certificate for RADIUS that clients do not trust

D.
The clients support the wrong form of encryption
