Reveal correct answer
Correct answer: D
Explanation
Hello: OSPF Hello messages are used for neighbor discovery and to establish and maintain adjacency between OSPF routers.
Database Description (DBD): OSPF DBD messages are used to exchange information about the OSPF database, including the list of LSAs and their sequence numbers.
Link State Request (LSR): OSPF LSR messages are used to request specific Link State Advertisements (LSAs) from neighboring routers when there is a discrepancy or missing information in the OSPF database.
Link State Update (LSU): OSPF LSU messages are used to advertise changes in the OSPF network, including new or updated LSAs, to neighboring routers.
Link State Acknowledgment (LSAck): OSPF LSAck messages are used to acknowledge the receipt of LSU messages and confirm the successful exchange of OSPF routing information between routers.
