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, S2, and S3 are all true.

B

S1, S2, and S3 are all false

C

S1 and S2 are true, but S3 is false.

D

S1 and S3 are true, but S2 is false
