How does OSPF ensure reliable delivery of link-state advertisements during flooding?

By using TCP for all OSPF packets

By requiring every router to send a Link State Acknowledgment for each received LSA

By using sequence numbers in Hello packets

By sending each LSA twice to every neighbor

What information is included in a Link State Request packet to identify the desired LSA?

The router ID of the requesting router only

The LSA type, Link State ID, and Advertising Router

Two OSPF routers are in the ExStart state during adjacency formation. The master/slave relationship is being negotiated. Which field in the Database Description packet is used to determine which router is the master?

The Router ID in the OSPF header.

What is the role of the Database Description packet in OSPF adjacency formation?

To flood new LSAs to all neighbors

To establish bidirectional communication

To synchronize the link-state databases by exchanging summaries

To request specific LSAs from the neighbor

OSPF Packet Types JN0-364 Practice Questions (Page 2)

Part of the Open Shortest Path First (OSPF) domain, which makes up ~15% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~5–9 in this domain), expect 1–1 from this objective — we provide 24 practice questions to prepare you well beyond it.
