Explanation

Gateway is correct because it acts as the entry/exit point between a local network and external networks, routing traffic from workstations to outside destinations - including command and control (C2) servers used by malware. Security tools monitor gateway traffic to detect suspicious outbound connections that reveal malware infections.

• Repeater (A) only amplifies signals to extend network range; it doesn't route or inspect traffic.
• Hub (C) broadcasts data to all connected devices on a local segment but has no routing intelligence or external connectivity.
• NIC (D) is the hardware adapter that connects a single device to a network; it handles local transmission, not routing between networks.

Memory tip: Think of a Gateway as the "gatekeeper" of your network - all traffic going in or out must pass through it, making it the ideal choke point for catching malware "calling home" to a C2 server.
