Routers populate their routing tables by learning network destinations using what three types of routes?

• A. Static, default, and dynamic routes.
• B. Local, remote, and proximal routes.
• C. Internal, external, and virtual routes.
• D. Primary, secondary, and tertiary routes.

Answer: (A)

Routers populate their routing tables with three kinds of routes: static routes configured manually, dynamic routes learned through routing protocols, and a default route that acts as a catch-all for destinations not explicitly listed in the table. Static routes give predictable, fixed paths; dynamic routes are learned and updated automatically as the network changes; the default route forwards packets toward an upstream neighbor when no specific match exists in the table. This combination lets routers have stable, adaptable, and wide-reaching routing behavior.
