Question

Your organization is hosting a wireless network with an 802.1x server using PEAP. On Thursday, users report they can no longer access the wireless network. Administrators verified the network configuration matches the baseline, there aren't any hardware outages, and the wired network is operational. What is the MOST likely cause for the problem?

Answer 1

The most likely cause for the problem is an issue with the authentication server or the server certificate. PEAP uses a server-side certificate to verify the identity of the authentication server. Administrators should check the server certificate, renew or replace it if necessary, and ensure it is properly installed and configured on the 802.1x server.

Step-by-step explanation:

The most likely cause for the problem is an issue with the authentication server or the server certificate.

PEAP (Protected Extensible Authentication Protocol) uses a server-side certificate to verify the identity of the authentication server.

If the certificate on the server has expired or is invalid, users will not be able to authenticate and access the wireless network.

To resolve the issue, administrators should check the server certificate, renew or replace it if necessary, and ensure it is properly installed and configured on the 802.1x server.
