What could cause this?

A client device associates to an SSID provisioned with 802.1X authentication. The client is configured for PEAP-MSCHAPv2 authentication. EAP termination (AAA-Fastconnect) is disabled on the controller, but the client continuously cycles through the authentication process.

What could cause this? (Choose two.)
A . The VLAN is not provisioned for the SSI
C . The DHCP server is not enabled.
D . The controller does not support PEAP in this mode.
E . The client receives an expired or revoked server certificate.
F . The wrong EAP type is configured on the client.
