Refer to the exhibit.
A network administrator sets up 802.1X authentication to a RADIUS server on an AOS-Switch. The RADIUS server and user devices are both set up to use PEAP
MSCHAPv2. The administrator tests the authentication and sees the output shown in the exhibit. Which issue could cause this output?
The exhibit shows that the RADIUS server is reachable and that there are no accepts or rejects, but there are also no challenges. This suggests that the failure is occurring early in the authentication process, possibly at the secure tunnel establishment phase. In PEAP MSCHAPv2, a certificate is required for the server to create a secure tunnel before the MS-CHAPv2 authentication can occur. If the switch does not have a certificate for port-access installed, the tunnel cannot be established, and hence, the authentication cannot proceed beyond this point.
B is correct
