CWNA: Certified Wireless Network Administrator v108 — Question 3

ABC Company is planning a point-to-multipoint outdoor 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 802.1X Authenticator?

Answer options

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

Correct answer: D

Explanation

The root bridge acts as the 802.1X Authenticator in this scenario, as it is responsible for managing authentication requests and responses. The Ethernet switch and RADIUS server do not perform this role, and while non-root bridges participate in the network, they do not authenticate users.
