Huawei HCIP-Datacom-Advanced Routing & Switching Technology V1.0 Sample Questions (Q229-Q234):

NEW QUESTION # 229
The figure shows the logical network architecture of a migration project. The purpose of the migration is to add network device R4 between R2 and R3.
* OSPF runs between network devices.
* After the physical network is connected, a network engineer incorrectly imports the backup configuration of R3 to R4 during the migration.
Given this, which of the following statements are true?

Options:

Answer: A,B

Explanation:
Comprehensive and Detailed In-Depth Explanation:
1. Understanding OSPF Neighbor Relationships
* OSPF (Open Shortest Path First) forms neighbor relationships based on these key conditions:
* Routers must be in the same OSPF area.
* The subnet mask and network type must match.
* The Hello/Dead timers must match.
* Authentication (if enabled) must match.
2. Analyzing the Given Scenario
* R1 and R2 are in Area 0 (Backbone Area).
* R3 and R4 are in Area 1 (Non-Backbone Area).
* R4 was configured incorrectly using R3's backup configuration, which could cause issues.
3. Evaluating Each Answer Option
* Option A: "The OSPF neighbor relationship between R1 and R2 is not affected."
* Correct.
* R1 and R2 are both in Area 0 and their configuration was not changed.
* Since R4 was added only between R2 and R3, it does not impact R1 and R2.
* # A is correct.
* Option B: "An OSPF neighbor relationship can be established between R2 and R4."
* Incorrect.
* R2 is in Area 0, but R4 is incorrectly configured using R3's backup, which likely placed it in Area 1.
* OSPF neighbors cannot form across different areas unless an Area Border Router (ABR) is properly configured.
* Since there is no indication of an ABR setup, the adjacency will fail.
* # B is incorrect.
* Option C: "An OSPF neighbor relationship can be established between R3 and R4."
* Correct.
* R3 and R4 are both in Area 1, and R4's backup configuration comes from R3, meaning they likely have identical settings.
* Since they share the same area and are directly connected, an OSPF adjacency is possible.
* # C is correct.
* Option D: "An OSPF neighbor relationship can be established between R1 and R3."
* Incorrect.
* R1 is in Area 0, and R3 is in Area 1.
* OSPF does not form neighbor relationships between different areas unless configured as an ABR, which is not mentioned.
* # D is incorrect.
Final Answer:
# A and C are correct.

NEW QUESTION # 230
When deploying MPLS/BGP IP VPN, regarding the use of BGP to exchange routing information between PE-CE, which of the following description is wrong?

Answer: A


NEW QUESTION # 231
When VPN traffic is transmitted in a typical BGP/MPLS IP VPN network, it usually contains two layers of labels. Which of the following descriptions about these two layers of labels are wrong?
(Multiple choice)

Answer: B,C,D


NEW QUESTION # 232
MPLS is called multi-protocol label switching. Which description is correct about the label in MPLS? (Multiple choice)

Answer: A,C,D


NEW QUESTION # 233
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?

Answer: A,B,D

Explanation:
Comprehensive and Detailed In-Depth Explanation:
Understanding the LSA Table in the Figure
The LSDB (Link-State Database) of R4 displays an Intra-Area-Prefix-LSA for Area 0.0.0.1. The table contains:
* Three LSAs originating from R4 (10.0.4.4)
* Prefixes referencing both Router-LSAs and Network-LSAs
* Different Sequence Numbers and Checksums, indicating multiple link-state changes OSPFv3 LSA Types Relevant to the Question
* Router-LSA (Type 1)
* Generated by every router to describe its links within an area.
* Network-LSA (Type 2)
* Generated only by the Designated Router (DR) for multi-access networks (such as Ethernet).
* Advertises all routers connected to the same segment.
* Intra-Area-Prefix-LSA (Type 9)
* Advertises IPv6 prefixes associated with a Router-LSA (Type 1) or Network-LSA (Type 2).
Analysis of Each Statement
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.
