Which statement is true regarding dynamic routing protocols?

Dynamic routing protocols are specifically designed to automatically adjust to changes in the network. This includes the ability to discover new routes and react to changes in the network topology, such as the addition or failure of routers and links. Unlike static routing, where routes must be manually configured and maintained by a network administrator, dynamic routing protocols utilize algorithms to calculate the best paths in real time, making them more adaptive and flexible. This capacity for dynamic adjustment allows for improved network resilience and efficiency, as routers exchange routing information and update their tables accordingly without requiring human intervention.

In this context, the other options describe characteristics that are not true for dynamic routing protocols. For instance, they do adapt to changes in the network and do not require manual intervention for finding new paths. Additionally, while the efficiency of static versus dynamic routing can depend on the specific circumstances and requirements of a network, dynamic routing is generally praised for its ability to handle changes seamlessly, regardless of static routing's potential efficiency in certain scenarios.
