How does LSA flooding affect OSPF convergence time?

LSA flooding increases convergence time because it adds overhead to every router

LSA flooding has no impact on convergence because SPF is run only on a timer

Faster flooding of LSAs can reduce convergence time by allowing routers to update their databases and run SPF sooner

LSA flooding only affects convergence in multi-area networks, not single-area networks

A network engineer is analyzing OSPF packet captures and sees a router sending a Link-State Update packet containing a Type 1 LSA to a neighbor. The neighbor responds with a Link-State Acknowledgment. What does this exchange indicate about the LSA flooding process?

The LSA is being flooded to synchronize the databases after a neighbor relationship is established.

The LSA is old, and the neighbor is requesting a newer copy.

The LSA is being retransmitted because the neighbor did not acknowledge it previously.

The LSA is new to the neighbor, and the acknowledgment confirms successful receipt.

What is the purpose of the OSPF database overload (database overflow) feature?

To increase the flooding rate to speed up convergence

To prioritize certain LSAs over others during flooding

To force a router to flush all LSAs and rebuild its database from scratch

To prevent a router from accepting or flooding LSAs when its LSDB exceeds a configured limit

What is the primary purpose of configuring an OSPF stub area?

To reduce the number of LSAs flooded into the area by blocking Type 5 external LSAs

To prevent routers in the area from forming adjacencies with each other

To increase the speed of SPF calculations by using a faster algorithm

To allow the area to accept Type 5 LSAs but not Type 3 LSAs

LSA Flooding JN0-664 Practice Questions (Page 4)

Part of the OSPF domain, which makes up ~19% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~7–11 in this domain), expect 1–1 from this objective — we provide 19 practice questions to prepare you well beyond it.
