Which router must stay available to ensure GameCon has a working connection to the internet?

• A. Router A
• B. Router B
• C. Router C
• D. Router D

Answer: (A)

The essential idea is that the edge router—the device that connects the local network to the internet—must stay online. This router acts as the gateway between your LAN and the outside world, handling crucial tasks like NAT, firewall protection, and directing traffic to and from the internet. If that router goes down, devices on the network can’t reach the internet, even if all the other routers are up and functioning internally. So keeping the edge router online keeps GameCon connected to the outside world. The other routers may manage internal traffic or Wi‑Fi, but they don’t provide the actual path to the internet, which is why the edge router is the one that must remain available.
