NEW QUESTION # 233
When a client invokes the iMaster NCE-Campus RESTful API, it sends an HTTP request. The server then returns the status code 401.
Which of the following errors has occurred?
Answer: B
Explanation:
Comprehensive and Detailed Explanation:
# HTTP Status Code 401 Unauthorized indicates that authentication credentials were either:
* Missing (e.g., no API key or token).
* Invalid (e.g., expired session, incorrect credentials).
# Error Code Breakdown:# (D) "Unauthorized" (Correct) # Indicates the client must authenticate first.# (A) "Service Unavailable" (503) # Used when the server is down.# (B) "Access Denied" (403) # Used when the client lacks permission even after authentication.# (C) "Not Found" (404) # Used when the resource does not exist.

NEW QUESTION # 235
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
Answer: C
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 # 236
Network Quality Analysis (NQA) is a real-time network performance detection and measurement technology.
It monitors the performance of multiple protocols running on a network. Which of the following protocols can be monitored by NQA?
Answer: D
Explanation:
Huawei'sNQA (Network Quality Analysis)provides tools to test and monitor network performance such as latency, jitter, and packet loss. The supported test types include:
ICMP- For reachability and round-trip time testing.
UDP,TCP,HTTP,FTP, etc.
DNS,VoIP,DHCP(limited to simulation, not monitoring protocol status itself) Protocols likeSNMPandOSPFarenot directly monitored by NQA, as these aremanagement or control plane protocols, not data-path or performance-measurable protocols.
Correct answer: C. ICMP
