Question

Consider the following three statements about link state and distance vector routing protocols, for a large network with 500 network nodes and 4000 links [S1] The computational overhead in link state protocols is higher than in distance vector protocols. [S2] A distance vector protocol (with split horizon) avoids persistent routing loops, but not a link state protocol. [S3] After a topology change, a link state protocol will converge faster than a distance vector protocol. Which one of the following is correct about S1, S2, and S3?

A S1 and S3 are true and S2 is false Correct Answer Incorrect Answer
B S1 and S2 are true and S3 is false Correct Answer Incorrect Answer
C S2 and S3 are true and S1 is false Correct Answer Incorrect Answer
D S1, S2 and S3 are true Correct Answer Incorrect Answer
