Question 75

If no area is divided, which of the following statements regarding the link-state routing protocol are true?

Routers in the same routing domain may repeatedly receive the same link state information.

Routers in the entire routing domain have the same LSDB.

Each router establishes a routing domain topology.

Each router learns routing entries from updated routing information and adds them to the routing table.

The router sends all link state information from a neighbor to all other neighbors to ensure data synchronization in the database.
