Refer to the exhibit. A company has an Aruba Instant AP cluster. A Windows 10 client is attempting to connect a WLAN that enforces WPA3-Enterprise with authentication to ClearPass Policy Manager…

Question

• Dwhether EAP-TLS is enabled in the AAA Profile settings for the WLAN on the IAP cluster

Explanation

In the context of WPA3-Enterprise with EAP-TLS authentication, the error message "Client doesn't support configured EAP methods" suggests that the client is not able to complete the EAP-TLS authentication process. EAP-TLS requires that both the server (in this case, CPPM) and the client have a valid certificate for mutual authentication. Windows 10 does support EAP- TLS natively, so options A, C, and D can be ruled out. The most likely reason for the authentication failure is that the client device does not have the correct client certificate installed, which is required to establish a TLS session with the server. Therefore, ensuring that the client has a valid certificate installed that matches the server's requirements is the correct step to resolve this issue. Reference: The need for valid certificates in EAP-TLS is outlined in RFC 5216 (The EAP-TLS Authentication Protocol), which specifies that both the client and server must present a valid certificate for EAP-TLS to succeed.
