What is a major benefit of using dynamic routing protocols?

1. Manual route calculation

2. Automatic population of new routes

3. Management of static routes

4. Enhancement of network security

The correct answer is: Automatic population of new routes

The major benefit of using dynamic routing protocols is that they provide the automatic population of new routes. This capability allows routers within a network to exchange information about reachable networks, making real-time adjustments to routing tables without requiring manual intervention. As network topologies change, such as when new devices are added or when links go down, dynamic routing protocols can quickly adapt and find the best paths for data packets. This enhances network reliability and efficiency, particularly in larger networks where manual route management would be too cumbersome or impractical. The other choices reflect aspects of routing but do not capture the primary advantage of dynamic routing protocols. Manual route calculation would imply a lack of automation, which contradicts the purpose of dynamic protocols. Management of static routes does not leverage the automation capabilities inherent in dynamic protocols. Finally, while dynamic routing can improve aspects of network security indirectly by ensuring that routes are current and optimal, enhancing network security is not its primary function.
