What is a router that directs packets between two separate LANs?

• A. Edge Router
• B. Interior Router
• C. Exterior Router
• D. Core Router

Answer: (C)

Routing packets between different networks requires a device that sits at the boundary of those networks and can forward traffic to the correct destination subnet. When two separate LANs are involved, the router that handles this inter-network communication is the exterior router. It acts as the gateway at the network edge, directing traffic between the two LANs (and to any other external networks) by using routing tables and protocols to know how to reach each LAN’s subnet. Interior routers are typically used for routing within a single organization’s internal layout, while core routers stay deep in the backbone. Edge/exterior routers focus on boundary connections and inter-network paths, which is why this one is the best fit for directing packets between two LANs.
