Exam CWNA-109 Topic 5 Question 123 Discussion

Actual exam question for CWNP's CWNA-109 exam
Question #: 123
Topic #: 5
In an 802.1X/EAP authentication exchange, what device acts as the "authenticator" that relays authentication messages between the client and the authentication server?

Suggested Answer: B Vote an answer

In an 802.1X/EAP framework, there are three roles: the supplicant, which is the client device requesting network access; the authenticator, which is the access point or WLAN controller that controls access to the network and relays EAP messages between the supplicant and the authentication server; and the authentication server, typically a RADIUS server, which validates the credentials and makes the final access decision. The authenticator does not make authentication decisions itself; it simply passes messages back and forth and enforces the outcome.
