Which statement best describes when static routing is preferred over dynamic routing?

• A. In networks with frequent topology changes and large scale.
• B. In networks that require automatic reconfiguration.
• C. In small, stable networks where manual management is feasible.
• D. In environments with diverse routing protocols.

Answer: (C)

Static routing is preferred when the network is small and stable, so you can manage routes by hand without the overhead of dynamic protocols. In such environments, routes don’t change often, making manual configuration practical and easy to keep up to date. This setup offers predictable, fast-path routing since nothing needs to be learned or exchanged between devices. It also uses fewer CPU, memory, and bandwidth resources because there’s no routing protocol chatter. Dynamic routing, on the other hand, is better for larger networks or networks with frequent topology changes, where automatic route discovery and adaptation are valuable. Environments with multiple routing protocols or frequent reconfigurations would be less suited to static routing.
