Difficulty: EasyAAA Framework and Authentication Methods

An administrator is configuring 802.1X port-based authentication on an enterprise network switch. Which component in the 802.1X architecture refers to the client workstation or software requesting access to the network?

  1. SupplicantAnswer
  2. B
    Authenticator
  3. C
    Authentication Server
  4. D
    Ticket-Granting Service

Answer

Supplicant
Under the IEEE 802.1X standard, the supplicant is the software daemon or client device attempting to gain network authorization through an authenticator.

Step-by-Step Solution

1
Identify the primary structural components of the IEEE 802.1X standard.
802.1X defines three key entities: the Supplicant, the Authenticator, and the Authentication Server.
Clear segregation of client software, access control hardware, and central credential databases is mandatory for 802.1X port security.
2
Determine which role corresponds to the host or software initiating the connection request.
The host endpoint or client agent running on the connecting system is designated as the supplicant.
The supplicant presents credentials to the authenticator (switch/AP), which encapsulated EAP messages to pass to the backend authentication server.
