NEW QUESTION # 39
Fill in Blank
On a VXLAN-based virtualized network, if the fabric networking mode is centralized gateway networking, the gateway is located on the _____ device. (Capitalize the first letter.)
Answer:
Explanation:
SpineInVXLANcentralizedgatewaynetworking
Explanation:
SpineIn VXLAN centralized gateway networking, the default gateway (for both intra- and inter-subnet traffic) is placed on the Spine node, which acts as a centralized gateway device.This architecture simplifies routing and enables centralized control for inter-VNI routing. It is often contrasted with distributed gateway mode, where gateways reside on leaf nodes.Huawei Datacom Reference:"In centralized gateway mode, the spine node functions as the gateway and processes both inter-VNI routing and gateway services."(Source: HCIE-Datacom V1.0 Official Training - VXLAN & Fabric Networking Chapter, Section: VXLAN Gateway Deployment Modes)
NEW QUESTION # 40
An O&M platform mainly provides unified monitoring and performance management for network devices.
Which of the following is NOT device monitoring data?
Answer: B
Explanation:
Understanding Network Monitoring Data Categories
#Network devices operate across three functional planes:
#A. Management Plane:
Handlesdevice configuration, authentication, and monitoring.
Example:SNMP, SSH, NETCONF logs.
#B. Data Plane (Forwarding Plane):
Handlespacket forwarding and switching.
Example:Interface statistics, traffic rates, dropped packets.
#C. Control Plane:
Handlesrouting, signaling, and protocol operations.
Example:BGP, OSPF, and MPLS signaling messages.
#D. Monitoring Plane (Incorrect Choice):
There is no "monitoring plane" in network architecture.
Monitoring tools collect data frommanagement, control, and data planes, butdo not form a separate plane.
Why is the Answer D (Monitoring-plane data)?
#Monitoring-plane does not exist as a separate category in network architecture.
#O&M tools collect data from management, control, and data planes, but do not define a separate "monitoring plane".
Real-World Application:
Huawei iMaster NCE-Campus & iMaster NCE-WANcollect real-timenetwork statistics and alarms.
Network Performance Monitoring (NPM)toolsanalyze control-plane eventsto detect failures.

NEW QUESTION # 41
During telemetry static subscription, the NMS delivers subscription configuration to devices for data sampling. Which of the following statements is incorrect about the sampling path huawei-debug:debug/cpu-infos/cpu-info?
Answer: A
Explanation:
In YANG model syntax:
cpu-info can be a list node (✓)
cpu-infos can be a container node (✓)
The sampling path does follow the YANG model hierarchy (✓)
However, the prefix huawei-debug: indicates the YANG module name, not an actual data node. Therefore, debug is not necessarily the top node in the YANG hierarchy - it is a node under the huawei-debug namespace/module.
Exact Extract - Huawei Telemetry and YANG Modeling Guide:
"The format <module-name>:<data-node> is used in telemetry to indicate paths. The actual top-level node may differ from the module name." Reference:
Huawei Telemetry Configuration Guide

The following description of 8021S deployment characteristics is correct?( Multiple choice question)
Answer: A
NEW QUESTION # 43
On the campus network shown, IPv6 is deployed for service tests. Four routers are deployed on the network, and OSPFv3 is used for IPv6 network connectivity. An engineer checks the LSDB of R2 and obtains a Link-LSA. Which of the following statements about the LSA are correct?
Answer: A,C,D
Explanation:
In OSPFv3, Link-LSA (Type 8) is generated by a router for each of its interfaces to advertise:
The router's link-local address on that interface.
The IPv6 prefixes associated with the interface.
Flags and options, such as router priority or loopback indicators.
From the output:
Link-LSA (Interface GigabitEthernet0/0/0)
Originating Router: 10.1.2.2
Link-Local Address: FE80::2E0:FCFF:FECD:4F79
Prefix: 2001:DB8:2345:23::/64
A . The link-local address of R2's GE0/0/0 is FE80::2E0:FCFF:FECD:4F79→ This matches the Link-Local Address field in the LSA. ✅ B . The IPv6 address prefix of R2's GE0/0/0 is 2001:DB8:2345:23::/64→ This matches the Prefix field in the LSA. ✅ C . This LSA indicates that R2 does not support external routes but can participate in IPv6 route calculation→ ❌ Incorrect.
The Link-LSA does not provide any indication about external route capabilities.
It simply advertises interface-specific IPv6 and link-local info.
Whether R2 supports external routes depends on Type 5 (External) or Type 7 (NSSA) LSAs, not Link-LSAs.
D . This LSA is generated by R2→ The Originating Router: 10.1.2.2 is R2's router ID, so this LSA is definitely generated by R2. ✅ Correct Answers: A, B, D The Link-LSA in OSPFv3 contains:
The link-local address used by the originating router on the link.
A list of all IPv6 prefixes associated with the link.
Flags such as router priority and the Router-LSA options.
These LSAs are always generated by the router itself and are not flooded beyond the link.
