Differentiate static and dynamic routing with an example dynamic routing protocol.

Differentiate static and dynamic routing with an example dynamic routing protocol.

• A. Static routing uses manually configured routes; dynamic routing uses protocols like OSPF or EIGRP.
• B. Static routing relies on routing protocols to learn paths.
• C. Static routing uses direct connections; dynamic routing uses only direct connections.
• D. Static routing uses OSPF; dynamic routing uses BGP.

Answer: (A)

Static routing relies on routes you configure by hand, and those paths don’t change unless you edit them. Dynamic routing uses protocols to discover paths and keep them updated automatically as the network topology changes. An example of a dynamic routing protocol is OSPF, which lets routers talk to each other, learn the best routes, and adjust if links go down or metrics change. This combination—manually configured routes for static routing versus protocol-driven path learning for dynamic routing—is exactly what differentiates the two. That’s why this choice is the best: it clearly states static uses manually configured routes and dynamic routing relies on protocols like OSPF or EIGRP to learn and maintain paths. The other options mix up the concepts (static routing doesn’t rely on routing protocols, static isn’t limited to direct connections, and while dynamic routing can be OSPF or BGP, static is not defined by those protocols).
