Why might an administrator choose dynamic routing over static routing?

An administrator might choose dynamic routing over static routing primarily to simplify initial configuration because dynamic routing protocols automatically discover and maintain the routes in the network. This means that when a dynamic routing protocol is utilized, the network routers can automatically learn about other routers and networks in the topology without requiring the administrator to manually configure routes. This reduces the complexity involved in setting up routing tables, especially in larger networks where the number of routes can be extensive and constantly changing due to network growth or topology changes.

Dynamic routing also adapts to changes in the network, such as new devices being added or existing devices failing, allowing the routing paths to be updated automatically. This dynamic adaptability can greatly minimize the administrative overhead required to keep routing tables current, allowing network administrators to focus on other critical tasks instead of constantly monitoring and updating static routes.

In contrast, while dynamic routing adds greater flexibility, it does not inherently provide more security, enable manual adjustments in the way typically desired by static configurations, or guarantee faster data transfer, as those aspects depend more on the network’s design and the routing protocols used rather than the routing method itself.
