A technician needs to enable remote connections to a workstation that is to be accessed from an external network. Which of the following settings on the router needs to be configured?

The correct answer is C. Port forwarding. Port forwarding (also called destination NAT or PAT) directs incoming traffic on a specific external port to a specific internal IP address and port. When a remote user on the internet tries to connect to the workstation (e.g., via RDP on port 3389), the router uses port…

Explanation

Port forwarding (also called destination NAT or PAT) directs incoming traffic on a specific external port to a specific internal IP address and port. When a remote user on the internet tries to connect to the workstation (e.g., via RDP on port 3389), the router uses port forwarding to pass that traffic through to the correct internal machine. Without it, the router would have no instruction on where to send the incoming connection and would simply drop it. NAT by itself translates addresses but does not route unsolicited incoming traffic. QoS prioritizes traffic bandwidth. DHCP assigns IP addresses to clients on the local network. Only port forwarding enables the specific incoming connection routing required for external remote access.
