Explanation / Answer

1)

RIP uses lots of bandwidth as it sends periodic updates, but OSPF advertise only changes in a network.

RIP can be reached hop count of 15 routers, but OSPF can reach unlimited hop counts.

RIP is a distance vector protocol which advertises network updates periodically; in RIP, the advertisements are sent every 30 seconds, and it too triggers updates when a change in network happens. It uses hop counts to calculate the metric value, which determines the best path to reach a network. RIP supports maximum of 15 routers, and 16th hop is considered unreachable or unsharable. So, RIP can be used efficiently in small networks only.

a) border

b) interior

c) interior

d) border
