JN0-349 Exam - Question 51
Show AnswerHide Answer
Correct Answer: B
In OSPF (Open Shortest Path First), each router maintains a complete and identical link-state database of the network topology. This means that R3, being an OSPF router, will have the full OSPF database. The OSPF neighbor states shown reinforce this, as there are multiple Full states reported, indicating complete adjacencies with those neighbors. Therefore, R3 does indeed have the complete OSPF database.

Jan 29, 2023I think that only B is good. R1 and R2 are going to be respectively DR and BDR cause of the priority value (255 and 254). R3 and R4 will be DRothers. This mean that A is wrong. C is also wrong beacuse R3 and R4 will not form full adjacency (only 2way state) cause they are DRothers and it also told us that answer D is wrong. So we can assume that B is good answer maybe because we can see that DR and Drother router know about all neighbors so it has complete database.

Jun 23, 2023The correct answer is B not because the other ones are wirng and by elimination we arrive at the correct choice. The real reason is that Link State Routing Protocols indeed have a complete database depicting the whole network shared and synchronized among anyone router, that is, this is a fundamental building block for a Link State Protocol.
