Refer to the exhibit.
A company has two HP Unified Wired-Wireless controllers. The MSM APs in Area 1 in the exhibit are controlled by Controller1. The MSM APs in Area 2 in the exhibit are controlled by Controlled. The company purchases a Controlled to provide backup for both Controller1 and Controller2 (N+1 redundancy).
How does the administrator set up the APs in Area 1 so that they contact Controlled if Controller1 fails?
A. Create a roam group that includes Controller1, Controlled, and Controlled. Make sure that Controlled has the highest IP address
B. Create AP templates for the area 1 APs on Controlled and set its connection priority for these APs to 7.
C. Create a backup AC configuration group between Controller1 and Controlled. Enable Fast Backup on the group.
D. On Controller1, configure the new controller’s IP address as the backup controller for the APs
