Huawei HCIP-Datacom-Core Technology V1.0 Sample Questions (Q123-Q128):

NEW QUESTION # 123
The BFD Echo function checks the connectivity of the forwarding link by looping back packets. Which of the following statements are true about this function?

  • A. If URPF is enabled on the peer end, BFD packets may be incorrectly discarded on the peer end.
  • B. The BFD Echo function applies only to single-hop BFD sessions.
  • C. When configuring a BFD session supporting the BFD echo function, you need to configure both the local and remote discriminators.
  • D. In the BFD Echo function, the device uses the IP address of the outbound interface as the source IP address by default.

Answer: A,D

Explanation:
Comprehensive and Detailed Step-by-Step Explanation:
1. What is the BFD Echo Function?
* BFD (Bidirectional Forwarding Detection) is used to detect link failures.
* The Echo function is an optional feature that tests link connectivity by looping back packets sent from the local device through the forwarding path.
2. Analysis of Each Statement:
Option A: If URPF is enabled on the peer end, BFD packets may be incorrectly discarded on the peer end.
* Correct.
* URPF (Unicast Reverse Path Forwarding) checks whether the source IP address of an incoming packet is reachable via the interface it was received on. Since the Echo function uses loopback packets, this can conflict with URPF, causing the packets to be dropped.
Option B: In the BFD Echo function, the device uses the IP address of the outbound interface as the source IP address by default.
* Correct.
* By default, the outbound interface's IP address is used as the source address for BFD Echo packets.
Option C: The BFD Echo function applies only to single-hop BFD sessions.
* Incorrect.
* The BFD Echo function can be used for both single-hop and multi-hop BFD sessions.
Option D: When configuring a BFD session supporting the BFD Echo function, you need to configure both the local and remote discriminators.
* Incorrect.
* The BFD Echo function is locally configured and does not require setting remote discriminators. The function operates independently of the remote device's configuration.
3. Summary:
* The correct statements are A and B.


NEW QUESTION # 124
IGMPV3 not only supports IGMPv1 General Query and IGMPv2 Group-Specific Query, and also IGMPv3 Source/Group-Specific Query.

  • A. FALSE
  • B. TRUE

Answer: B


NEW QUESTION # 125
Similar to the OSPF DR, the IS-IS DIS needs to be elected on a broadcast network. However, the OSPF DR is preemptive by default, whereas the IS-IS DIS is not preemptive by default.

  • A. FALSE
  • B. TRUE

Answer: B

Explanation:
DIS and DR Election
* The IS-IS Designated Intermediate System (DIS) is responsible for generating and updating pseudonode LSPs on a broadcast network.
* Unlike OSPF DR, the IS-IS DIS does not preempt by default. This behavior avoids unnecessary flapping in the network due to frequent DIS re-elections.
HCIP-Datacom-Core Reference
* The characteristics of DIS and DR behavior are explained in IS-IS network operation chapters.


NEW QUESTION # 126
An enterprise office network runs OSPF and is divided into multiple OSPF areas. Enterprise network engineers can configure route summarization on ASBRs to reduce the number of inter-area Type 3 LSAs, which in turn reduces the routing table size and improves device resource utilization.

  • A. FALSE
  • B. TRUE

Answer: A

Explanation:
Comprehensive and Detailed in-depth Step-by-Step Explanation:To answer this question, it is essential to distinguish between the roles of ABRs and ASBRs in OSPF and the function of route summarization:
* Route Summarization on ABRs:
* Route summarization in OSPF can reduce the number of inter-area Type 3 LSAs that ABRs propagate between areas.
* ABRs perform route summarization to reduce the amount of routing information exchanged between areas, thereby decreasing the size of the routing table and improving resource utilization.
* Route Summarization on ASBRs:
* ASBRs summarize external routes (from outside OSPF) into Type 5 LSAs or Type 7 LSAs (in NSSAs).
* ASBR route summarization does not impact inter-area Type 3 LSAs because ASBRs are responsible for importing and summarizing external routes, not summarizing routes between OSPF areas.
Since the statement refers to configuring route summarization on ASBRs to reduce inter-area Type 3 LSAs, it is incorrect. Route summarization for inter-area Type 3 LSAs must be configured on ABRs, not ASBRs.
Correct Statement: Route summarization on ABRs reduces the number of inter-area Type 3 LSAs.
References:
* Huawei HCIA-Datacom Study Guide, Chapter on "OSPF Route Summarization".
* RFC 2328 - OSPF Version 2.


NEW QUESTION # 127
On an OSPF network, if a router receives an update of an LSA that exists in the local LSDB, the router updates the LSDB and floods the LSA.

  • A. FALSE
  • B. TRUE

Answer: A

Explanation:
OSPF LSA Flooding Mechanism
* If a router receives an LSA identical to one already in its LSDB, it does not flood the LSA again unless the LSA has changed (i.e., the sequence number or content has been updated).
* OSPF ensures efficient use of bandwidth by avoiding redundant flooding of unchanged LSAs.
HCIP-Datacom-Core Reference
* The OSPF LSDB synchronization process explains that unchanged LSAs are not reflooded, ensuring stability and resource optimization.
