63. Frage
On an OSPF network, OSPF routers exchange LSAs to synchronize their LSDBs. If an OSPF router receives an LSA that does not exist in its LSDB, it updates its LSDB and floods the LSA.
Antwort: B
Begründung:
In OSPF (Open Shortest Path First), each router maintains aLink-State Database (LSDB), which must be synchronized with other routers in the same area. When an OSPF router receives anLSA (Link-State Advertisement)that it doesnot already have in its LSDB, it takes the following steps:
It updates its LSDB with the new LSA.
It floods the LSA to all its other OSPF neighbors (except the one from which it received the LSA).
This ensures that all routers in the OSPF area eventually converge to the same network topology.
Reference from Huawei HCIP-Datacom-Core Technology Study Guide:
"When an LSA is received and it is newer or not present in the LSDB, the router updates the LSDB and floods the LSA to other neighbors to ensure database synchronization." (Chapter: OSPF Fundamentals - Section: LSDB Synchronization)
64. Frage
In an OSPF routing domain, two routers must be specified as one DR and one BDR in a broadcast or NBMA network with at least two routers.
Antwort: B
Begründung:
In an OSPF broadcast or NBMA network with at least two routers, one router must act as the DR (Designated Router), and another as the BDR (Backup Designated Router) to ensure efficient communication and reduce the number of adjacencies. This is a requirement for OSPF operation in such network types .
65. Frage
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.
Antwort: B
Begründung:
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.

66. Frage
BFD can associate with multiple protocols to quickly detect faults.
Which of the following functions are supported?(Select all that apply)
Antwort: A,B,C
Begründung:
BFD (Bidirectional Forwarding Detection)is a lightweight protocol that providesrapid detectionof faults in the forwarding path between two routers or switches.
It worksin conjunction with routing protocolsand provides fast failure detection to enable quick route convergence.
Protocol support:
B: BFD for static routes- Supported. BFD tracks the reachability of next-hop addresses and can trigger route removal upon failure.
C: BFD for OSPF- Supported. BFD can be associated with OSPF to accelerate the detection of neighbor failures.
D: BFD for BGP- Supported. BFD enables sub-second detection of BGP peer failures.
A: BFD for PIM-Not supported. PIM (Protocol Independent Multicast) typically does not use BFD for neighbor failure detection.
Reference from Huawei HCIP-Datacom-Core Technology Study Guide:
"BFD can be associated with static routes, OSPF, IS-IS, BGP, and other protocols to quickly detect link or device faults and trigger fast rerouting." (Chapter: High Availability Technologies - Section: BFD Principles and Applications)
67. Frage
When using Route-Policy 's if-match to create a matching rule, which of the following BGP attributes cannot be matched?
