You are asked to configure an OSPF network based on the topology shown in the exhibit. You must keep the link-state database in Area 1 as small as possible.What will accomplish this?
A.
Area 0 should be configured as a stub area so that it will not announce routes into Area 1.
B.
Area 1 should be configured as an NSSA to limit the size of the link-state database.
C.
Area 1 should be configured as a stub area with no-summaries to limit the size of the link-state database.
D.
Area 0 should be configured with a virtual link to R4 to limit the size of the Area 1 link-state database.
I think the answer should be B. Because there is a ASBR in area 1, so we need to advertise the external RIP route as a Type 7 route inside area 1. So Area 1 is a NSSA instead of a Stub. Anyone agree?

B is correct as area has one ASBR so basically NSSA is nothing but stub which support LSA advertised by ASBR. So to support the ASBR we should go with B.

Type 7 LSAs allow an NSSA to support the presence of AS boundary routers and their corresponding external routing information. The ABR converts Type 7 LSAs into AS external (Type 5 ) LSAs and leaks them to the other area.
