An OSPF router in a service provider network has just originated a new Type 1 LSA. It floods this LSA to its directly connected neighbors. What is the primary purpose of the Link State Acknowledgment packet that the neighbors send back?

To confirm reliable delivery of the LSA, enabling the flooding process to be reliable.

To request a newer version of the LSA from the originating router.

To carry the full LSA to the originating router as a backup.

To inform the originating router that the LSA was not needed.

What is the primary function of a Link State Update packet in OSPF?

To discover neighbors on a network segment

To carry and flood link-state advertisements

To request missing LSAs from a neighbor

A network engineer is explaining OSPF operations to a junior colleague. The engineer states that OSPF uses five different packet types. Which two packet types are used during the initial neighbor discovery and database synchronization phases, respectively?

Link State Update and Link State Acknowledgment.

Database Description and Link State Update.

Hello and Database Description.
