What is a router that directs packets inside a LAN?

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

Answer: (D)

Routing traffic within a local network is handled by an interior router. This device sits inside the LAN and moves packets between devices on the same local network, or between subnets inside the LAN. It uses its routing table to decide the next hop for each destination and often acts as the default gateway for hosts, forwarding traffic toward other networks only when needed. This is different from exterior or edge routers, which sit at the boundary of the LAN to connect to external networks, and from core routers, which operate inside large backbone networks. So, for directing packets inside the LAN itself, the interior router is the appropriate term.
