What is the purpose of SPF throttling in OSPF?

To prioritize SPF runs for critical routes over less important ones

To prevent excessive SPF runs during network instability by delaying and spacing out computations

To reduce the size of the link-state database by removing stale entries

To increase the speed of SPF computation by using multiple CPU cores

In OSPF, how is the total cost of a path from one router to another calculated?

By taking the maximum interface cost along the path

By counting the number of hops and adding a fixed cost per hop

By summing the interface costs of all outgoing links along the path

By multiplying the interface costs of all links in the path

In the shortest-path tree, what does a leaf node typically represent?

A stub network or a router with no further reachable neighbors

A transit network that connects multiple routers

Which link-state database entries serve as the primary input to the SPF algorithm for computing intra-area routes?

Hello packets and database description packets

Link-state request packets and link-state acknowledgment packets

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 28 practice questions to prepare you well beyond it.
