Question

Consider the following statements about the routing protocols, Routing Information Protocol (RIP) and Open Shortest Path First (OSPF) in an IPv4 network .
I. RIP uses distance vector routing
II. RIP packets are sent using UDP
III. OSPF packets are sent using TCP
IV. OSPF operation is based on link-state routing
Which of the statements above are CORRECT?

• A. II, III and IV only
• B. I, II and III only
• C. I, II and IV only
• D. I and IV only

Answer 1

The correct option is C I, II and IV only

RIP uses distance vector routing. OSPF uses
link-state routing protocols.
RIP uses UDP as transport protocol.
OSPF neither uses TCP nor UDP.
[Link state packet should be given to all routers in subnet so it's not possible with TCP.
These link state packets should be reliable at that same time which is not possible with UDP.
