Which roaming situation using controllers in a Cisco Unified Wireless Network requires a client using WPA2 with PKC to reauthenticate to the network?
A. A wireless client roams to another AP on a different controller in the same mobility domain.
B. A wireless client roams to another AP on the same controller.
C. A wireless client roams to another AP after being out of range of the network for 2 minutes.
D. A wireless client roams to another AP on a controller in a different mobility domain.
I would say that is option A. Since the controllers trusted in each other (same Mobility group) and they pass along the keys info from their clients between them (WLCs).
