What is the reason for this?

You created a new SSID with the security settings shown in the exhibit.

Some, but not all users complain that client devices are unable to connect to this SS1D.

What is the reason for this?
A . The WPA3 Enterprise GCM-2S6 mode does not support transition mode.
B . WPA3 Enterprise is not backward compatible with WPA2 Enterprise.
C . MAC authentication after a failed 802. ix authentication is not possible as the option "MAC Authentication Fall-Through" is disabled.
D . The primary servers shared key differs from the shared key configured for this server on HPE Aruba Networking Central.

Answer: C

Explanation:

If some users are unable to connect to an SSID configured with WPA3-Enterprise GCM-256, and the "MAC Authentication Fall-Through" is disabled, it means that devices which fail 802.1X authentication will not attempt MAC authentication. If these client devices are configured to use MAC authentication as a backup method, they will fail to connect, explaining the issue faced by some users.
