QuestionQ95

Security

A user is unable to connect to the wired network with 802.1X using EAP-TLS. The user’s device is configured correctly, and the user has a valid certificate. RADIUS server logs indicate that the user is authenticating successfully.

What might be causing this issue?

  • A There is an issue with the switch interface configuration.
  • B The user’s device is not using the correct certificate authority.
  • C The switch is not configured to use EAP-TLS.
  • D The RADIUS server is not configured to use EAP-TLS.
Explanation

Successful RADIUS authentication confirms that EAP-TLS and certificate validation are working between the client and RADIUS server. Wired access can still fail if the switch port is incorrectly configured for 802.1X authorization or its post-authentication network settings.
