What protocol is normally used for communication between an authenticator and authentication server on a network using 802.1x authentication?
A. RADIUS
B. TACACS
C. TACACS+
D. XTACACS
Correct Answer: A
In 802.1x authentication, the end user’s system contains a component called the supplicant that initiates the authentication process. The supplicant connects to the authenticator, normally a network switch or wireless access point, that then reaches out to an authentication server to confirm the user’s identity. The communication between the authenticator and authentication server normally takes place using the RADIUS and EAP protocols.
