JNCIS-SP: Juniper Networks Certified Specialist – Service Provider Routing (2023) — Question 13

Which OSPF database packet determines which router is in charge of the database synchronization and the transferring of LSA headers between the two systems?

Answer options

• A. link-state request
• B. database description
• C. hello
• D. link-state update

Correct answer: B

Explanation

The correct answer is B, as the database description packet is used in OSPF to establish which router will handle the synchronization of the link-state database and manage LSA header transfers. Options A, C, and D refer to other OSPF functions, such as requesting link-state information or establishing neighbor relationships, but do not specifically address database synchronization.
