CompTIA Network+ (N10-007) — Question 465

Several open conference rooms have active wired network connections. To discourage unauthorized users, a network technician wants to require users in the conference rooms to authenticate to the network before gaining access. Which of the following would be the BEST network technology to use?

Answer options

• A. WPA
• B. MAC filtering
• C. ACLs
• D. 802.1X

Correct answer: D

Explanation

The correct answer is 802.1X, as it provides port-based network access control, ensuring that only authenticated users can access the network. WPA primarily secures wireless networks but does not enforce user authentication for wired connections. MAC filtering can help but is not as secure since MAC addresses can be spoofed. ACLs control traffic flow but do not handle user authentication.
