Q

How does the RIB differ from the FIB?

A. The FIB maintains network topologies and routing tables. The RIB is a list of routes to particular network destinations.

C. The RIB is used to create network topologies and routing tables. The FIB is a list of routes to particular network destinations.

D. The RIB includes many routes to the same destination prefix. The FIB contains only the best route.

A

Q

What is the difference between CEF and process switching?

A. CEF processes packets that are too complex for process switching to manage.
