Which two considerations must a network engineer have when planning for voice over wireless roaming? (Choose two.)
Full reauthentication introduces gaps in a voice conversation.
Roaming time increases when using 802.1x + Cisco Centralized Key Management.
Roaming occurs when the phone has seen at least four APs.
Roaming occurs when the phone has reached -80 dBs or below.
Roaming with only 802.1x authentication requires full reauthentication.

A client roams between two APs that are registered to two different controllers, where each controller has an interface in the client subnet. Both controllers are running AireOS. Which scenario explains the client roaming behavior?
Controllers exchange mobility control messages (over UDP port 16666) and the client database entry is moved from the original controller to the new controller.
Controllers do not exchange mobility control messages (over UDP port 16666) andthe client database, entry is not moved from the original controller to the newcontroller.
Controllers exchange mobility control messages (over UDP port 16666) and a new client session is started with the new controller.
Controllers exchange mobility control messages (over UDP port 16666) and the client database entry is tunneled from the original controller to the new controller.
