A customer has deployed an AOS-10 mobility gateway cluster consisting of three controllers at a single site. The WLAN is configured to tunnel wireless device traffic to the AOS-10 mobility cluster…

The correct answer is C. The client device has an invalid pre-shared key. The issue indicated by the output is an invalid pre-shared key (PSK). The logs show multiple failures during the WPA2 key exchange process, which points to a mismatch between the PSK configured on the client device and the PSK expected by the AOS 10 mobility gateway.
