Correct answer: A
Answer: RIP runs at the application layer.
What this means: RIP is implemented as an application process on routers that exchanges routing updates with other routers.
Transport mechanism: RIP messages are carried using UDP (port 520), but using UDP does not make RIP a transport‑layer protocol.
Relationship to the network layer: RIP builds and updates the IP routing table, which is used by the network layer to forward packets; the protocol that produces those routing entries runs at the application layer.
Common confusion: Because RIP programs network‑layer routing tables, some learners think it is a network‑layer protocol. The correct view is that RIP is an application‑layer routing protocol that provides information to the network layer.
