Which of the following is an advantage of Link State algorithms?

• A. Fast Convergence Times
• B. Requires More CPU Power and Memory
• C. Complete Topology Picture, Non-reliant on Neighbors for Information
• D. Less Prone to Routing Loops

Answer: (D)

Link-state routing builds a complete map of the network and uses that map to compute routes with a shortest-path algorithm. Because every router floods its link information and then independently computes the best path to every destination, all routers converge on a consistent view and can choose loop-free paths. This global, deterministic decision process prevents the kind of inconsistent routing information that often creates loops in other approaches, making routing loops much less likely. While having a full topology view and not needing to rely on neighbors for every update are also realities of link-state protocols, the clear practical win in this context is the ability to derive loop-free routes from a shared network map.
