What statement differentiates static routes from dynamic routes?

• A. Dynamic routes require manual configuration.
• B. Static routes are manually created by network administrators.
• C. Static routes automatically calculate the best path.
• D. Dynamic routes are manually created by network administrators.

Answer: (B)

Static routes are manually configured by network administrators; you explicitly set the next-hop or exit interface in the router. This is what makes them fixed and predictable, since they don’t change unless you edit them.

Dynamic routes, by contrast, are learned automatically through routing protocols. Routers share information about network topology and metrics, allowing them to discover and continually update the best paths as conditions change. Because of this, static routes don’t automatically calculate the best path, while dynamic routes do rely on protocol updates to determine the optimal route.

The other statements mix up who configures the route or how paths are chosen, which is why they don’t describe the difference accurately.
