Controllers WLC_1 and WLC_2 are in different mobility domains. A wireless client that has the same VLAN
interface roams from WLC_1 to WLC_2. What happens to the client roaming?
A. The client context is deleted in controller WLC_1, and a new client context is created in WLC_2 to
become the anchor controller.
B. The client context is moved from controller WLC_1 to controller WLC_2. The result is that the WLC_1
client context is deleted and WLC_2 becomes the anchor controller.
C. The client context is copied from controller WLC_1 to controller WLC_2. The result is that WLC_1
becomes the anchor controller and WLC_2 becomes the foreign controller.
D. The client context is copied from controller WLC_1 to controller WLC_2. The result is that WLC_1
becomes the foreign controller and WLC_2 becomes the anchor controller.
Correct Answer: A
