Which is a reason for using a dynamic routing protocol?

A. You have a network with only a few routers and network per branch.
B. You have a network with only a few VLANs and one router.
C. You have a network with a large amount of VLANs and only one router.
D. You have a network with a few VLANs and many routers.

D. The scalability of routes between routers should always be considered when choosing a static routing design vs. a dynamic routing design. A few VLANs over many routers creates a lot of work when a new VLAN is created and static routing is being used. However, when one router is being used, the administrative overhead is low.
