In an OSPF network which two statements describe the link-state database (LSDB)? (Choose two.)

It can be viewed by using the show ip ospf database command.
It contains a list of all neighbor routers to which a router has established bidirectional communication.
All routers within an area have an identical link-state database.
It contains a list of only the best routes to a particular network.
A neighbor table is created based on the LSDB.

Explanation & Hint:

In an OSPF (Open Shortest Path First) network, the link-state database (LSDB) is a crucial component. Here are the descriptions that apply:

It can be viewed by using the show ip ospf database command.

This statement is true. The show ip ospf database command is used to display the contents of the OSPF link-state database. This database contains all the OSPF link-state advertisements (LSAs) that the router has received and processed, which are used to build the network topology.

All routers within an area have an identical link-state database.

This statement is also true. In OSPF, all routers within the same area should have an identical LSDB. This synchronization of the LSDB across all routers in an area is crucial for the correct operation of OSPF, as it ensures that all routers have a consistent view of the network topology. OSPF achieves this through the flooding of LSAs throughout the area.

The other statements are not accurate descriptions of the LSDB:

The LSDB does not simply contain a list of neighbor routers; it contains LSAs which describe the state of each router’s interfaces and links, the network’s topology, and more.
The LSDB does not only list the best routes. It contains comprehensive topology information that OSPF uses to compute the best routes.
While the neighbor table is an important part of OSPF’s operation, it is not directly created from the LSDB. The neighbor table is developed from direct communication between OSPF routers, independent of the LSDB.
