Which is an advantage of dynamic routing protocols?

The benefit of a dynamic routing protocol is that it creates resiliency when routes become unavailable. It does this by recalculating the best route in the network around the outage. When using dynamic routing protocols there is a higher RAM usage because of the route tables collected. CPU usage is also higher with dynamic routing protocols because of calculations. Bandwidth usage is also higher with dynamic routing protocols because of the traffic involved learning the various routes.
