Q: 10
Which OSPF database packet determines which router is in charge of the database synchronization
and the transferring of LSA headers between the two systems?

Its B. Database description packets set the master/slave roles for OSPF sync. Link-state request is just for missing LSAs, not control.
A tbh, since link-state request packets seem like they're doing the actual work of database sync by asking for LSAs that are missing. Database description feels more like just sharing summaries, not deciding who controls the process. I could be missing a detail but that's how I remember it from OSPF section. Anyone see it differently?
Probably B, not A. The link-state request is a common trap but the sync control actually happens with database description packets.
I don’t think it’s B. A should be the correct answer, since link-state request packets are used for database synchronization too, right? I remember similar questions mentioning that as a common trap.
B imo. The database description packet (DBD) is what OSPF uses during adjacency setup to decide the master/slave relationship between neighbors, so it determines who manages the sync and exchanges the LSA headers. The others like hello or update don't do this part. Pretty sure that's right but open to corrections.
