What is the main purpose of Dynamic Routing?

To manually specify routing table mappings
To determine the best route automatically
To provide redundancy in routing
To enhance network security

The correct answer is: To determine the best route automatically

The main purpose of dynamic routing is to determine the best route automatically. Dynamic routing protocols allow routers to communicate with each other and share information about network topology changes and the status of network paths. This enables routers to automatically update their routing tables based on the most efficient paths available at any given time. Dynamic routing is particularly beneficial in larger and more complex networks, where manual configuration of static routes would be cumbersome and prone to errors. With dynamic routing, routers can adapt to changes such as network congestion, link failures, or the addition of new network segments, thereby optimizing data transmission by selecting the most efficient routes on-the-fly. While redundancy, enhanced security, and manual routing are important aspects of network management, they do not capture the primary function of dynamic routing, which is the automatic determination of optimal routing paths in response to the network's current state.
