GATE 2017 CS (CS2) – Question 19

Computer Networks · Routing: Distance Vector and Link State Routing · 1 mark · Multiple choice

For RIP and OSPF in IPv4: I: RIP uses distance-vector routing. II: RIP packets use UDP. III: OSPF packets use TCP. IV: OSPF uses link-state routing. Which hold?

I and IV only
I, II and III only
I, II and IV only
II, III and IV only

Show answer and explanation

Correct answer: (C) I, II and IV only

Explanation

RIP exchanges distance vectors through UDP. OSPF builds a link-state database and runs directly over IP protocol 89, rather than TCP. Thus I,II,IV are true and III false, giving C.
