A network administrator is troubleshooting a client connection problem. In the process of collecting
information, a client debug is run on the controller for the device MAC address. What is the most
likely cause of the problem?

A.
WPA/802.1X Layer 2 security is enabled. Cisco Centralized Key Management is enabled. The logs
show an EAP/802.1X identity request failure, which points to a WLC issue. Client will be
deauthenticated.

B.
WPA2/802.1X Layer 2 security is enabled. The logs show a RADIUS identity request failure, which
points to a WLC issue. Client will immediately send an EAPOL-start packet to try again.

C.
WPA2/802.1X Layer 2 security is enabled. The logs show an EAP/802.1x identity request failure,
which points to a supplicant issue. Client will be deauthenticated.

D.
WPA PSK Layer 2 security is enabled. The logs show an EAP/802.1X identity request failure, which
points to a supplicant issue. Client will immediately send an EAPOL-start packet to try again.

E.
WPA2 PSK Layer 2 security is enabled. The logs show an EAP/802.1X identity request failure, which
points to a WLC issue. Client will be deauthenticated.
