CompTIA A+ Core 2 (220-1102) — Question 471

A technician is configuring a SOHO router and wants to only allow specific computers on the network. Which of the following should the technician do?

Answer options

• A. Configure MAC filtering.
• B. Disable DHCP.
• C. Configure port forwarding.
• D. Disable guest access.

Correct answer: A

Explanation

The correct answer is A, as configuring MAC filtering allows the technician to specify which devices can connect to the network based on their MAC addresses. Option B, disabling DHCP, would prevent devices from obtaining IP addresses, which is not a method to selectively allow devices. Option C, configuring port forwarding, is used for directing incoming traffic to specific devices but does not control access. Option D, disabling guest access, restricts guests but does not manage the permissions of specific devices.
