What are the three roles of the 802.1X framework, as defined by the 802.1X standard, that are performed by the client STA, the AP (or WLAN controller), and the RADIUS server? (Choose 3)
The IEEE 802.1X framework consists of three defined roles:
Supplicant (E): The client device (STA) that requests access to the network.
Authenticator (F): The network device (usually an AP or switch) that enforces access control and acts as an intermediary between the supplicant and the authentication server.
Authentication Server (D): Typically a RADIUS server that validates credentials and responds with access decisions.
Incorrect:
A & B. Enrollee and Registrar are roles in Wi-Fi Protected Setup (WPS), not 802.1X.
C. AAA Server is a broader term; the specific role in 802.1X is “Authentication Server.”
