When wired 802.

Wired 802.1X authentication is a port-based network access control that uses the physical characteristics of the switched LAN infrastructure to authenticate devices attached to a LAN port1. Wired 802.1X authentication requires three components: a supplicant, an authenticator, and an authentication server2. The supplicant is the client device that requests access to the network. The authenticator is the switch port that controls the access to the network based on the authentication result. The authentication server is the server that validates the credentials of the supplicant and sends the authentication result to the authenticator3.

In this question, option A is correct because Cisco Identity Service Engine (ISE) is an example of an authentication server that supports wired 802.1X authentication4. Option C is correct because Cisco Catalyst switch is an example of an authenticator that supports wired 802.1X authentication5. Option B is incorrect because Cisco AnyConnect ISE Posture module is not a supplicant, but a software component that checks the compliance status of the supplicant. Option D is incorrect because Cisco ISE is not an authenticator, but an authentication server. Option E is incorrect because Cisco Prime Infrastructure is not an authentication server, but a network management tool.
