CompTIA Network+ (N10-009) — Question 62

An administrator is configuring a switch that will be placed in an area of the office that is accessible to customers. Which of the following is the best way for the administrator to mitigate unknown devices from connecting to the network?

Answer options

• A. SSE
• B. ACL
• C. Perimeter network
• D. 802.1X

Correct answer: D

Explanation

The correct answer is D, 802.1X, as it provides port-based network access control, ensuring that only authenticated devices can connect. Options A (SSE) and C (Perimeter network) do not specifically address device authentication, while B (ACL) is more about filtering traffic rather than controlling access based on device identity.
