What typically characterizes the operation of dynamic routing protocols?

Dynamic routing protocols are characterized by their ability to automatically adjust to changes in the network. This means that when there is a change in the topology, such as a router going down or a link becoming unavailable, dynamic routing protocols can detect these changes and recalibrate the routing paths without requiring manual intervention. This adaptability enhances the flexibility and efficiency of the network, allowing for more resilient and automated traffic management.

In contrast, other options describe characteristics that are typical of static routing or manual network configurations. For instance, the manual entry of routes and reliance on static configurations highlight the lack of adaptability associated with dynamic routing. Dynamic routing is specifically designed to improve network performance and reliability by continuously evaluating and updating the best paths for data transmission, making option B the best choice in this context.
