Which statement correctly describes the contents of the OSPF link-state database on a router?

It contains only the LSAs originated by the router itself

It contains only the LSAs for directly connected networks

It contains identical LSAs for all routers within the same OSPF area

It contains the complete routing table with next-hop information

What is a distinguishing characteristic of a Not-So-Stubby Area (NSSA)?

It blocks all Type 3 summary LSAs from entering the area

It requires all routers in the area to be configured with the same area ID

It does not allow any external routes to be injected into the OSPF domain

It allows an Autonomous System Boundary Router (ASBR) to be placed inside the area

A network engineer is troubleshooting an OSPF issue where a router is not learning routes from a neighbor. The engineer checks the OSPF neighbor table and sees the neighbor in the Full state. What does the Full state indicate?

The routers have exchanged Hello packets but have not yet synchronized their databases.

The routers have elected a DR and BDR and are ready to exchange routing information.

The routers have completed database synchronization and have identical link-state databases.

The routers are in the process of exchanging LSU packets.

Part of the OSPF domain, which makes up ~4% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~1–2 in this domain), expect 1–1 from this objective — we provide 29 practice questions to prepare you well beyond it.
