CompTIA Network+ (N10-008) — Question 540

A computer engineer needs to ensure that only a specific workstation can connect to port 1 on a switch. Which of the following features should the engineer configure on the switch interface?

Answer options

• A. Port tagging
• B. Port security
• C. Port mirroring
• D. Port aggregation

Correct answer: B

Explanation

The correct answer is B, Port security, as it allows the engineer to define which specific devices can connect to a port based on MAC addresses. The other options do not provide the necessary access control: A (Port tagging) is used for VLAN identification, C (Port mirroring) is for monitoring traffic, and D (Port aggregation) combines multiple ports for increased bandwidth.
