CompTIA A+ Core 1 (220-1001) — Question 204

A technician is setting up a new SOHO router for a home user. The user has a media server to be accessible from the Internet while the user is traveling.
Which of the following should the technician configure to allow access to the server from the Internet?

Answer options

• A. Port forwarding
• B. NAT
• C. MAC filtering
• D. QoS

Correct answer: A

Explanation

Port forwarding is the correct choice as it allows external traffic to reach the media server by directing incoming requests on specific ports to the server's local IP address. NAT, while related, primarily translates IP addresses rather than directing specific traffic. MAC filtering restricts access based on device MAC addresses and does not apply to internet accessibility for servers. QoS prioritizes network traffic but does not facilitate access to a server from the Internet.
