CWNA: Certified Wireless Network Administrator v107 — Question 16

ABC Company is planning a point-to-multipoint bridge deployment with standalone (autonomous) 802.11 bridge units. 802.1X/EAP will be used for bridge authentication. A Linux-based RADIUS server will be used for authentication. What device in the bridge implementation acts as the 802.11X Authenticator?

Answer options

• A. All non-root bridges
• B. The root bridge
• C. The Ethernet switch
• D. The RADIUS server

Correct answer: D

Explanation

The RADIUS server acts as the 802.1X Authenticator, managing the authentication process for devices connecting to the network. The root bridge and non-root bridges do not perform authentication but facilitate the bridge connectivity. The Ethernet switch also does not handle the authentication process directly; that responsibility lies with the RADIUS server.
