How does an OSPF router handle a newly received LSA during the flooding process?

It only forwards the LSA to the Designated Router on the network

It immediately installs the LSA in the LSDB and forwards it to all neighbors except the one it was received from

It discards the LSA if it is not directly connected to the source router

It waits for an acknowledgment before installing the LSA in the LSDB

What is the primary purpose of the LSA flooding process in OSPF?

To establish and maintain OSPF neighbor adjacencies

To calculate the shortest path to each destination

To elect the Designated Router on a multi-access network

To ensure that all routers in an area have an identical link-state database

What is the purpose of the Database Description (DBD) packet in the OSPF LSDB synchronization process?

To acknowledge the receipt of LSAs

To summarize the LSDB contents so routers can determine which LSAs they need to exchange

To request specific LSAs from a neighboring router

To establish the OSPF neighbor adjacency

An OSPF router has just completed the SPF calculation and has installed routes in the routing table. A new LSA arrives that changes the topology. What is the router's immediate action regarding the routing table?

It schedules a new SPF calculation and updates the routing table after the calculation completes.

It sends the new LSA to all neighbors and waits for their acknowledgment before recalculating.

It immediately updates the routing table with the new LSA information without running SPF.

It waits for the LSA to age out before recalculating routes.

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 22 practice questions to prepare you well beyond it.
