Which term refers to a table containing information about all routers in a network and their routes, acting as a network roadmap?

• A. Topology Table
• B. Top-Level Domain (TDL)
• C. Throughput Tester
• D. Time-to-Live (TTL)

Answer: (A)

Topology table holds all learned routes to destinations and the routers that advertise them, acting like a network roadmap. This table lets the routing process compare multiple possible paths and their costs, so it can determine the best route to forward traffic and quickly recompute if a link changes. In many routing protocols, the topology table feeds the routing table, which stores only the chosen, active paths used for forwarding. The other options don’t fit: a top-level domain is a DNS suffix, a throughput tester measures performance, and Time-to-Live is a field in the IP header that limits hops, not a map of routes.
