JNCIS-ENT: Juniper Networks Certified Specialist – Enterprise Routing and Switching (2025) — Question 25

What is a purpose for the OSPF database description packet?

Answer options

• A. to transfer the LSA headers between two systems
• B. to determine who is in charge of database flushing
• C. to transfer the LSUs between two systems
• D. to determine who is in charge of adjacency formation

Correct answer: A

Explanation

The correct answer is A because the OSPF database description packet is specifically designed to facilitate the transfer of LSA headers, allowing routers to synchronize their databases. Option B is incorrect as database flushing is not determined by this packet, while C is wrong because LSUs (Link State Updates) are transferred via different packets, not database description packets. Option D is also incorrect since adjacency formation is managed through different OSPF processes, not related to the database description packet.
