Certified Information Systems Security Professional (CISSP) — Question 136

Which function does 802.1X provide?

Answer options

• A. Network intrusion detection system (NIDS)
• B. Wireless access point (WAP)
• C. Wi-Fi Protected Access (WPA)
• D. Network Access Control (NAC)

Correct answer: D

Explanation

The correct answer is D, as 802.1X is primarily used for implementing Network Access Control (NAC) by providing an authentication mechanism for devices attempting to connect to a network. Options A, B, and C are incorrect because they refer to different network security and access technologies that do not specifically pertain to 802.1X functionality.
