Which of the following best describes the difference between a link-state and a distance-vector routing protocol?

A.
A link-state protocol uses more metrics than a distance-vector protocol when making a route decision.

B.
A link-state protocol makes routing decisions based on the number of hops between the source and destination and a distance-vector protocol makes the decision based on distance.

C.
A distance-vector protocol looks at the congestion of a link and a link-state protocol does not.

D.
A distance-vector protocol builds a more accurate routing table than a link-state protocol

Explanation:
Distance-vector routing protocols make their routing decisions on the
distance (or number of hops) and a vector (a direction). The protocol takes these
variables and uses them with an algorithm to determine the best route for a packet.
Link-state routing protocols build a more accurate routing table because they build
a topology database of the network. These protocols look at more variables than just
number of hops between two destinations. They use packet size, link speed, delay,
loading, and reliability as the variables in their algorithms to determine the best
routes for packets to take.
