Implementing Cisco Enterprise Wireless Networks (ENWLSI) — Question 146

A wireless engineer must configure IEEE 802.1X authentication on a WLAN that supports new and legacy wireless devices. Which condition must be met for the legacy clients to be able to associate and authenticate without issues?

Answer options

• A. The authenticator and the authentication server must support the same authentication protocol.
• B. The client and the authenticator must support the same authentication protocol.
• C. The client and the controller must support the same authentication protocol.
• D. The client and the authentication server must support the same authentication protocol.

Correct answer: B

Explanation

The correct answer is B because for legacy clients to successfully connect and authenticate, they need to use a compatible authentication protocol with the authenticator. Options A, C, and D do not ensure that the client can communicate effectively with the authenticator, which is essential for authentication in a WLAN environment.
