What are the three databases maintained by a Link State Protocol?
A Link State Protocol maintains three main databases: the neighbor database, the topology database, and the forwarding database. The neighbor database keeps track of all the directly connected neighbors (adjacency information), the topology database contains the entire network topology, and the forwarding database is used to make forwarding decisions.
All of them are incorrect. The right answer would be: adjacency, topology, forwarding
B is the answer. Adjacency database is known as neighbor database. Topology database is known as link-state database. Routing information base(RIB) sometimes called the forwarding database.
