CompTIA Network+ (N10-008) — Question 515

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

Enabling port security is the correct answer because it allows the switch to limit the devices that can connect based on MAC addresses. ACLs control traffic but do not limit device connections, a captive portal is not typically used in this context, and disabling unnecessary services does not directly affect device connectivity.
