Huawei HCIE-Datacom V1.0 Sample Questions (Q303-Q308):

NEW QUESTION # 303
The following information is displayed during OSPF troubleshooting. Based on this information, which of the following is the cause of the failure in establishing an OSPF adjacency relationship?
<Huawei>display ospf error interface GigabitEthernet 0/0/0
OSPF Process 1 with Router ID 10.0.12.2
OSPF error statistics
Interface: GigabitEthernet0/0/0 (10.0.12.2)
General packet errors:
0 : Bad version 0 : Bad checksum
0 : Bad area id 0 : Bad authentication type
0 : Bad authentication key 0 : Unknown neighbor
0 : Bad net segment 0 : Extern option mismatch
0 : Router id confusion
HELLO packet errors:
2 : Netmask mismatch 0 : Hello timer mismatch
0 : Dead timer mismatch 0 : Invalid Source Address

A. Hello packets are sent at different intervals.
B. The IP address masks of the interfaces are inconsistent.
C. The authentication passwords are inconsistent.
D. The area types are inconsistent.

Answer: B

Explanation:
According to the displayed OSPF error statistics from the Huawei device, the key HELLO packet error shown is:
yaml
CopyEdit
2 : Netmask mismatch
This indicates that the OSPF adjacency formation is failing due to a subnet mask mismatch between the two OSPF neighbors on the corresponding interface (GigabitEthernet 0/0/0). OSPF uses the subnet mask in Hello packets to ensure that neighbors are in the same network. If the masks do not match, OSPF will not form an adjacency.
From the Huawei Official HCIE-Datacom Study Guide (Version 3.0) - under the OSPF Troubleshooting Section:
"Netmask mismatch: If the subnet mask configured on the interfaces of OSPF neighbors does not match, a 'Netmask mismatch' error occurs. OSPF requires neighbors to be on the same subnet to establish an adjacency. This is a common reason for failure in adjacency formation." (Reference: Huawei HCIE-Datacom V3.0, OSPF Troubleshooting Chapter, Section 4.2 - OSPF Hello and Adjacency Establishment Issues) Thus, among the given options:
A . Area type inconsistency would result in an area ID mismatch error, not netmask.
B . Authentication mismatch would show a bad authentication key or type error.
D . Hello interval mismatches would trigger a Hello timer mismatch error.
Only C. The IP address masks of the interfaces are inconsistent directly matches the actual error observed: Netmask mismatch.

NEW QUESTION # 304
The following is an error in the OSPF routing calculation (single choice).

A. OSPF router uses the FULL SPF algorithm to calculate all nodes in the network when initially calculating routes
B. Compared to the PRC algorithm, the ISPF algorithm only calculates the changed leaf nodes when the route changes PRC algorithm to recalculate routes
C. When the first and second class LSAs on the network change, OSPF uses the ISPF algorithm to recalculate the routes The

Answer: B

NEW QUESTION # 305
In the multi-level RR scenario, the first-level RR will be connected to a large number of second-level R, which may cause the BGP circuit of the first-level RR to overflow from the table Risk of R BGP routing table overflow?( Radio).

A. ORF
B. Route Control
C. Set the same Cluster-ID
D. Route Aggregation

Answer: D

NEW QUESTION # 306
The following description of the BGP route reflector is ?( Multiple choice questions).

A. Cluster_List is an optional non-staging property for ring protection within the cluster.
B. The Originator_ID attribute is generated by the Route Reflector (RR) for inter-cluster ring protection.
C. The route learned from the client, all non-clients and clients published to this RR.
D. A network of bones is divided into multiple reflection clusters, each of which configures the other RRs as non-clients, and establishes an IBGP full connection between the RRs.

Answer: C,D

NEW QUESTION # 307
In the CloudCampus public cloud scenario, if deployment through the Huawei registration query center is used, you do not need to configure DHCP Option 148 on the DHCP server of the campus network.

A. FALSE
B. TRUE

Answer: B

Explanation:
Comprehensive and Detailed In-Depth Explanation:
In theCloudCampus public cloud scenario, when devices are deployed through theHuawei registration query center, there isno need to configure DHCP Option 148on the campus network's DHCP server.
Theregistration query centerautomatically provides thecontroller IP addressto the devices during the registration process.
DHCP Option 148is typically used to provide theiMaster NCE-Campus addressin on-premises or private cloud scenarios.
In thepublic cloud scenario, the devices obtain this information directly from the Huawei cloud platform, makingOption 148 unnecessary.
