An engineer has configured the wireless controller to authenticate clients on the employee SSID against Microsoft Active Directory using PEAP authentication.
Which protocol does the controller with the authentication server?
A. WPA2
B. RADIUS
C. 802.1X
D. EAP
Correct answer is B. EAP is used between supplicant (client) and the authenticator (AP, WLC).
I think RADIUS is not protocol
Correct answer is B
As controller is authenticator and uses RADIUS messages to connect with AD server
RADIUS Access Request message will be sent from WLC to AD server
