What is a primary advantage of dynamic routing over static routing?

• A. It Automatically Updates Routes When the Network Changes
• B. It Requires Manual Configuration
• C. It Cannot Adapt to Link Failures
• D. It Increases Administrative Overhead Unnecessarily

Answer: (A)

Dynamic routing protocols automatically learn and adjust routes by exchanging information with neighboring routers. The main advantage is that routes are updated automatically whenever the network changes. If a link fails or a new subnet is added, routers recompute the best paths and propagate those changes, so reachability is maintained without manual edits. This leads to faster convergence and better scalability as the network grows. Static routing, by contrast, requires manual configuration for every route and cannot adapt automatically to failures. While some administrative tasks are still needed to manage dynamic protocols, they reduce ongoing manual maintenance in larger networks because routes are learned and updated automatically.
