Options

Aauthentication server: Cisco Identity Service Engine
Bsupplicant: Cisco AnyConnect ISE Posture module
Cauthenticator: Cisco Catalyst switch
Dauthenticator: Cisco Identity Services Engine
Eauthentication server: Cisco Prime Infrastructure

Explanation

For wired 802.1X authentication, a network access device acting as an authenticator (like a Cisco Catalyst switch) and an authentication server (like Cisco Identity Services Engine) are essential components. The switch forwards authentication requests to the server, which validates the user/device credentials.

Common mistakes.

B. While Cisco AnyConnect ISE Posture module can act as a supplicant, the core required components for 802.1X are the authenticator (switch) and authentication server (ISE).
D. Cisco Identity Services Engine (ISE) functions as the authentication server in 802.1X, not the authenticator.
E. Cisco Prime Infrastructure is a network management system and does not function as an authentication server for 802.1X.

Concept tested. 802.1X authentication components
