What is a disadvantage of using dynamic routing protocols?

  1. They are only suitable for simple topologies.
  2. Their configuration complexity increases as the size of the network grows.
  3. They send messages about network status insecurely across networks by default.*
  4. They require administrator intervention when the pathway of traffic changes.

Explanation: By default, dynamic routing protocols forward messages across a network without authenticating the receiver or originator of traffic. Static routes increase in configuration complexity as the network grows larger and are more suitable for smaller networks. Static routes also require manual intervention when a network topology changes or links become disabled.
