Solution
The correct sequence for the generic IEEE 802.1X/EAP authentication process is "Supplicant to authenticator to authentication server". So, option D is the correct answer.
Here's a step-by-step breakdown of the process:
- The Supplicant (client device) connects to the Authenticator (network access device).
- The Authenticator blocks all traffic except for EAP from the Supplicant.
- The Supplicant sends an EAP-start message. The Authenticator responds with an EAP-request identity message.
- The Supplicant replies with an EAP-response packet containing the identity to the Authenticator.
- The Authenticator forwards the EAP-response packet to the Authentication Server.
- The Authentication Server sends a challenge to the Supplicant via the Authenticator.
- The Supplicant sends the response to the challenge to the Authentication Server via the Authenticator.
- If the response is correct, the Authentication Server notifies the Authenticator that the Supplicant is authenticated.
- The Authenticator opens the port for the Supplicant, allowing full network access.
