The default IEEE 802.1X AP authentication configuration on a Cisco Catalyst 9800 Series Wireless Controller uses EAP-FAST (Extensible Authentication Protocol - Flexible Authentication via Secure Tunneling) with CAPWAP DTLS (Datagram Transport Layer Security). This provides secure authentication and encryption for communication between the AP and the controller.
I am going with C
How can you not have port authentication using dot1x which points to a AAA Radius Server. Without having the configs set on the port- ours is global on the switch- how does a client get authenticated?
The default IEEE 802.1x AP authentication configuration on a Cisco Catalyst 9800 Series Wireless Controller is EAP-PEAP with 802.1x port authentication, not EAP-FAST with CAPWAP DTLS.
Look at section - Verifying the Authentication Type makes it look like C

I don't agree. It doesnt say anywhere that is mandatory. The opposite, it says it is very flexible and that it can be applied to a certaing group of APs is desired.
I would go with D, even if someone or the exam correctors say NOT.
I have also applied for the cisco learning course and labs and it is not mandatory
