In SSL/TLS protocol, what kind of authentication is supported?

A.
Peer-to-peer authentication

B.
Only server authentication (optional)

C.
Server authentication (mandatory) and client authentication (optional)

D.
Role based authentication scheme

Explanation:
“The server sends a message back to the client indicating that a secure session
needs to be established, and the client sends it security parameters. The server compares those
security parameters to its own until it finds a match. This is the handshaking phase. The server
authenticates to the client by sending it a digital certificate, and if the client decides to trust the

server the process continues. The server can require the client to send over a digital certificate for
mutual authentication, but that is rare.”
