A small business is choosing between static and dynamic routing for its network. Which of the following is the best reason to use dynamic routing in a growing network?
A.
Easier to configure compared to using manually entered routes
B.
Does not require additional network security controls
C.
Features enhanced network monitoring and visibility
D.
Includes automatic changes and updates in network topology
Dynamic routing is most beneficial in a growing/changing network because it can automatically learn, adapt, and update routes as the topology changes. In Network+ (N10-009) routing objectives, dynamic routing protocols exchange routing information between routers and recalculate paths when links go down, new networks are added, or metrics change. This reduces the operational burden and the risk of human error that increases as the environment scales. With dynamic routing, adding a new subnet or branch often requires far fewer manual updates because routers propagate new route information automatically, and convergence mechanisms help restore connectivity after failures.
Option A can be partly true in large environments, but the core “best reason” emphasized for dynamic routing is the automatic adaptation to topology changes. Option B is incorrect—dynamic routing may introduce additional security considerations (route filtering, authentication, neighbor control). Option C is not a defining advantage; monitoring visibility depends on tools/telemetry rather than routing type. Therefore, the strongest and most correct reason is automatic changes and updates in network topology.
