CompTIA Network+ (N10-009) — Question 21

A network administrator is configuring a new switch and wants to ensure that only assigned devices can connect to the switch. Which of the following should the administrator do?

Answer options

• A. Configure ACLs.
• B. Implement a captive portal.
• C. Enable port security.
• D. Disable unnecessary services.

Correct answer: C

Explanation

The correct answer is C, as enabling port security will allow the switch to limit the devices that can connect based on their MAC addresses. Options A, B, and D do not specifically address the requirement of restricting connections to only assigned devices, making them less effective for this scenario.
