Which of the following is a disadvantage of Link State algorithms?

Explanation:
Link-state routing requires each router to maintain a complete map of the network and run a shortest-path calculation (SPF) whenever the topology changes. That means more memory is needed to store the entire topology and more CPU power to execute the SPF algorithm, especially as the network grows. Those higher resource demands are the main downside of link-state protocols. The other traits—fast convergence, a full topology view, and reduced routing loops—are advantages that come with this approach, not downsides.
