What is the primary purpose of dividing an OSPFv2 domain into multiple areas?

To allow routers to use different OSPF versions in the same network.

To enable the use of multiple routing protocols simultaneously.

To reduce the size of the link-state database and limit the flooding of LSAs.

To eliminate the need for a designated router on broadcast segments.

How does OSPFv2 determine the cost of a route by default on Juniper devices?

By using a fixed cost of 1 for all interfaces.

By using the reference bandwidth divided by the interface bandwidth.

By measuring the round-trip time to the destination.

By counting the number of hops to the destination.

What is the purpose of an OSPFv2 virtual link?

To enable OSPF to run over a non-IP network.

To connect a non-backbone area to the backbone area through a transit area.

To provide a backup path for data traffic in case the primary path fails.

To increase the bandwidth of a physical link between two routers.

You are troubleshooting an OSPF adjacency that keeps flapping. The two routers are connected via a slow WAN link. You notice that the adjacency goes down and comes back up periodically. Which timer adjustment is most likely to stabilize the adjacency?

Decrease the retransmit interval

Which OSPFv2 router role is responsible for connecting the backbone area to a non-backbone area?

Autonomous System Boundary Router (ASBR)

OSPFv2 JN0-650 Practice Questions (Page 1)

Part of the Interior Gateway Protocols (IGPs) domain, which makes up ~12% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~4–7 in this domain), expect 1–2 from this objective — we provide 36 practice questions to prepare you well beyond it.
