Which routing approach uses routing protocols to automatically adjust routes and consumes more processing power?

• A. Routing table
• B. Static routing
• C. Dynamic routing
• D. Broadcast message

Answer: (C)

Dynamic routing uses routing protocols to automatically adjust routes in response to topology changes, and it tends to require more processing power because the router must run protocols, exchange updates with neighbors, and continuously recompute the best paths. This ongoing activity lets the network adapt to link failures or congestion without manual reconfiguration, trading extra CPU and memory use for greater flexibility and resilience. In contrast, static routing relies on manually configured routes and doesn’t involve running routing protocols, so it uses far less processing power. The routing table is simply the stored set of known routes, which can be populated statically or by dynamic methods, but the approach described here is about automatic adjustment via protocols. A broadcast message, meanwhile, is a method of delivering a packet to all hosts in a local area and is not itself a routing approach.
