Explanation
The routing table is the authoritative data structure a router consults to determine the next-hop address for forwarding a packet.
Common mistakes.
- A. Link state refers to a routing protocol type (e.g., OSPF) that describes the state of links, not a lookup structure for per-packet forwarding decisions.
- C. Routing metrics are values used by routing protocols to select the best path when building the routing table, but they are not directly consulted per packet.
- D. Convergence is the process by which all routers in a network agree on topology; it is a state, not a data structure used for forwarding.
