Which term describes a compiled list of routers and their routes that network devices use to determine possible paths?

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

Answer: (A)

The main idea here is how a router knows which paths are available to reach destinations. A topology table captures the network’s layout—showing the routers and the routes between them—so devices can determine which paths to use for forwarding packets. This compiled map helps decide possible next hops and alternate routes if one path fails, guiding efficient and correct forwarding decisions. Why this fits best: it directly describes the stored view of the network's structure and routes that devices consult to pick a viable path. The other terms aren’t about routing decisions: a top-level domain relates to naming hierarchies, a throughput tester measures performance, and Time-to-Live is a field in IP packets that limits hop count rather than mapping routes.
