Exam NSE7_EFW-7.2 topic 1 question 61 discussion

Hey everyone! This question can be a bit tricky, but I believe I’ve found the answer. We know that the DR is responsible for generating Type 2 LSAs. Meanwhile, the BDR acts as a standby and takes over if the DR fails. As long as the DR is operational, the BDR does not generate Type 2 LSAs. It simply maintains full adjacency with all routers, ready to become the DR should the current one fail. Additionally, any router that is connected to the backbone area (Area 0) and also to multiple other areas is considered an ABR. Resources: Study guide 7.2 p 360-362 p 365 p 367

Type 1 LSAs (Router LSAs): These are sent by all routers to describe their interfaces and the state of the links. Type 2 LSAs (Network LSAs): These are sent by the designated router (DR) and the backup designated router (BDR) to describe the multi-access networks they are part of.

Since router D is BDR it will not generate LSA2. In this case will generate only LSA1 in both area and LSA3 from 0 to 1 and from 1 to 0

BDR generate LSA type 1 and 3 because is a Border Router

Answer is D. I think there might be an error in the question. The router seems to be an ABR.
