A. Supplicants and the Authentication Server per 802.1X
B. Network Access Servers and the Authentication Server per RADIUS
C. VPN clients and the Network Access Server per L2TP
D. Wireless devices and the Access Point per PEAP
Kindly be reminded that the suggested answer is for your reference only. It doesn’t matter whether you have the right or wrong answer. What really matters is your reasoning process and justifications.
My suggested answer is A. Supplicants and the Authentication Server per 802.1X.
Wentz’s book, The Effective CISSP: Security and Risk Management, helps CISSP and CISM aspirants build a solid conceptual security model. It is a tutorial for information security and a supplement to the official study guides for the CISSP and CISM exams, and an informative reference for security professionals.
In 802.1X, supplicants communicate with the authenticator, which forwards authentication messages to the Authentication Server. Supplicants don’t authenticate to the authentication server directly.
Generally speaking, Network Access Servers (NASs) refer to servers providing remote access services, such as dial-up, VPN, etc. A VPN server can be viewed as one type of NAS.
