A small remote office is set to connect to the regional hub site via NSSA ASBR.
Which type of LSA is sent to the remote office OSPF area?

A. B. C. D.A.
In an OSPF network, routers within the same area share information using Link State Advertisements (LSAs). LSAs are packets that contain information about the state of the network, such as the router ID, network topology, and network links. Each LSA has a specific type, which defines its purpose and the type of information it carries.
In this scenario, the small remote office is connecting to the regional hub site via a Not-So-Stubby-Area Border Router (NSSA ASBR). A NSSA is a special type of OSPF area that allows external routes to be injected into the OSPF domain, while still keeping the area stubby. A NSSA ASBR is a router that injects external routes into a NSSA.
When a NSSA ASBR injects external routes into a NSSA, it generates a type 7 LSA. Type 7 LSAs are used to propagate external routes from a NSSA ASBR to other routers in the NSSA. Type 7 LSAs are flooded only within the NSSA and are not propagated to other areas.
Therefore, the correct answer is A. type 7 LSA.
