JNCIP-SP: Juniper Networks Certified Professional – Service Provider (2023) — Question 24

Which statement is correct about IS-IS when it performs the Dijkstra algorithm?

Answer options

• A. The local router moves its own local tuples into the candidate database.
• B. When a new neighbor ID in the tree database matches a router ID in the LSDthe neighbor ID is moved to the candidate database.
• C. Tuples with the lowest cost are moved from the tree database to the LSDB.
• D. The algorithm will stop processing once the tree database is empty.

Correct answer: B

Explanation

The correct answer is B because it accurately describes how the Dijkstra algorithm manages neighbor IDs in the context of the IS-IS protocol. The other options either misstate the process or describe actions that do not occur during the algorithm's execution.
