Final answer:
The answer is All of these. EAP is an authentication framework used in wireless networks, and there are different types of EAP protocols such as PEAP, EAP-TLS, and EAP-FAST.
Step-by-step explanation:
The answer to the question is Option A, All of these. EAP stands for Extensible Authentication Protocol, which is an authentication framework used in wireless networks. EAP is a general term that encompasses different types of protocols that provide secure communication between the client and the authentication server.
PEAP, EAP-TLS, and EAP-FAST are all specific types of EAP protocols. PEAP (Protected Extensible Authentication Protocol) uses a TLS tunnel to secure the authentication process. EAP-TLS (EAP-Transport Layer Security) uses certificates to authenticate the client and the server. EAP-FAST (EAP-Flexible Authentication via Secure Tunneling) is an alternative to PEAP and provides similar security features.
