87. Refer to the exhibit. You have decided to use the individual ports in trunking on your Cisco 4402-50 controller. You have placed one port on each separate switch as shown and you have fully loaded 50 access points on this controller, placing 25 APs on each physical port and associated AP manager interface. During a power outage, you have lost one of these switches. Your access layer is unaffected and all 50 access points still have power and attempt to move to the other physical port and rejoin the AP manager interface that remains up. How many access points will be able to connect to this controller?
Select the best response.
1646207842.jpg
A. All 50 APs will connect.
B. All APs will try to rejoin the controller no matter what interface goes down.
C. Each port can only support 48 APs and therefore 2 APs will not be able to join.
D. Only 25 APs will remain joined and the other APs will look for another controller.
