Huawei H12-831_V1.0 Exam - Topic 1 Question 44 Discussion

The router ID of R4 is 10.0.4.4. The LSA shown in the figure is displayed in the LSDB of R4.Which of the following statements are true about the LSA?A. The three LSAs belong to area 1. B. Area 1 is a stub area. C. No OSPFv3 neighbor relationship is established on at least one link of R4. D. R4 is the DR on a link.
A) The three LSAs belong to area 1. (True) The table explicitly shows 'Intra-Area-Prefix-LSA (Area 0.0.0.1)', meaning all LSAs are for Area 1. The Link State IDs also indicate intra-area advertisements. Statement A is correct.
B) Area 1 is a stub area. (False) There is no indication that Area 1 is a stub area. Stub areas do not receive Type 5 (External) LSAs, and the LSDB does not show Type 3 (Inter-Area) LSAs either. Network-LSAs (Type 2) are not typically seen in stub areas unless explicitly configured. Statement B is incorrect.
C) No OSPFv3 neighbor relationship is established on at least one link of R4. (True) One LSA references a Router-LSA, while two reference Network-LSAs. A Router-LSA alone suggests that R4 has at least one point-to-point or unnumbered link with no OSPFv3 adjacency. This means R4 has an interface with no neighbor (e.g., a passive interface or down link). Statement C is correct.
D) R4 is the DR on a link. (True) The presence of Network-LSAs (Type 2) indicates that a multi-access link exists. Since R4 is the origin of the Network-LSA, it must be the DR (Designated Router) for that link. Statement D is correct. Final Conclusion: A. The three LSAs belong to area 1. (True) B. Area 1 is a stub area. (False) C. No OSPFv3 neighbor relationship is established on at least one link of R4. (True) D. R4 is the DR on a link. (True) Thus, the correct answers are: A, C, D.

D is spot on, Network-LSAs mean R4 is the DR for sure!

I think I recall that if there's a Router-LSA, it might mean no neighbor relationship exists, but I’m not completely clear on how to interpret that in this context.

I feel confident that R4 is the DR based on the LSAs shown, but I need to double-check what it means for an area to be a stub.

I practiced a similar question where we had to identify the router ID and its LSAs, and I think I got confused about whether a stub area can have Type 2 LSAs.

I remember studying the types of LSAs, and I think the presence of Network-LSAs indicates R4 is the DR, but I'm not entirely sure about the stub area concept.

This is a tricky one. I'll need to review the OSPF concepts around LSAs and areas to make sure I'm interpreting everything correctly. Gotta be careful on the exam.
