Why must the distance between two IP networks be less than 16 routers when using RIP as a routing protocol?
A. RIP is a classful routing protocol.
B. RIP converges too slowly.
C. RIP uses a metric of 16 as infinite.
D. RIP uses 16 seconds as a hold timer.
Which two statements are correct about link-state routing protocols? (Choose two.)
A. Packets are routed based upon the shortest path to the destination.
B. Paths are chosen based upon the number of hops to the destination.
C. The exchange of advertisement is triggered by a change in the network.
D. In a multipoint network, all routers exchange routing tables directly with all the routers.
