Which term describes a router that directs packets inside a LAN?

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

Answer: (D)

Routing within a local area network is handled by an interior router. This device moves packets between hosts and subnets inside the LAN, making decisions about where to send each packet next so it reaches its destination inside the local network. The boundary that connects the LAN to other networks is typically handled by an edge (or exterior) router, which is designed to link the local network to external networks like a WAN or the Internet. In larger networks, a core router sits in the backbone to carry high-speed traffic between major network segments, not specifically inside a single LAN. So the router that directs packets inside the LAN is the interior router.
