Free Practice Questions for Huawei H19-301_V4.0 Exam

Huawei’s CloudCampus Solution includes a campus WAN interconnection component that supports communication between branches and with the headquarters or data centers.

The WAN interconnection model supports two main deployment options:

Static IPsec VPN (a traditional method using manually configured tunnels), and

SD-WAN interconnection (intelligent link selection, centralized control).

Huawei also provides “5D-WAN” capabilities — a suite of innovations that include application-based traffic steering, centralized management, dynamic link selection, and flexible deployment models.

A. True: TheAirEngine 6760R-51, a rugged outdoor Wi-Fi 6 AP,supports IoT expansionvia Huawei’sIoT cards.

B. False: Huawei IoT expansion is implemented viaIoT cards and dedicated expansion modules,not PCIe or USB.

C. False: Huawei supportsmultiple IoT protocols, includingBLE, RFID, Zigbee, andNB-IoT, not just RFID and Bluetooth.

D. False: AlthoughHuawei minimizes interferencethrough smart scheduling,some spectrum overlap may still occur, andco-channel interference is always considered in planning.

Huawei offersfour flexible Data Center Network (DCN) solutionstailored for diverse evolution scenarios involving multiple data centers and cloud environments:

A. Edge DC solution: Supports lightweight, edge data centers for branch or edge computing.

B. Multi-PoD solution: Designed to scale large DCs by creating multiple pods connected via a spine layer.

C. Multi-site solution: Enables interconnection between different physical data centers.

D. Multi-cloud and hybrid cloud solution: Provides seamless integration between private DCs and public cloud platforms.

These four are explicitly outlined in Huawei’s official data center solution materials.

Huawei’scampus network digital map, as part of theiMaster NCE-Campus solution, supportsmulti-level fault detection— notonly three levels. It enables:

Real-time network monitoring and alarm correlation

AI-based root cause analysis

One-second fault demarcation

Minute-level fault recovery and closure

Up to 90% improvement in fault locating efficiency

The phrase "only three levels" isincorrect— the system supportsmulti-layer analysis across users, applications, devices, and networks.

Huawei defines theWLAN network lifecycleusing acomprehensive four-stage model, which includes:

B. Plan: Network coverage, capacity, and performance planning

A. Construct: Deployment of APs, controllers, and configurations

C. Maintain: Ongoing network operation and fault handling

D. Optimize: Performance tuning, channel optimization, and roaming refinement

These stages are covered in theWLAN planning and deployment methodologyusing tools likeSCTandiMaster NCE-Campus.

According to Huawei's documentation on theiMaster NCE series, theiMaster NCE-IPis theonly controller that supports unified LAN and WAN management, providing centralized control, O&M, and intelligent policy enforcement across both LAN and WAN domains.

iMaster NCE-Fabric: Focuses on data center networks.

iMaster NCE-Campus: Primarily for campus LAN management.

iMaster NCE-WAN: Focuses only on WAN orchestration.

iMaster NCE-IP:Integrates LAN and WAN managementto offer end-to-end control.

WheniMaster NCE (controller) and the analyzerare deployed on asingle node (combined deployment),certain advanced functions are limited or unavailabledue to resource constraints:

A. ERSPAN,C. MDC (Multi-Domain Control), andD. IFIT (In-situ Flow Information Telemetry)are still supported in basic or partial forms.

B. Multi-cloud simulationis aresource-intensive featurethat requiresindependent, dedicated controller and simulation nodesfor cloud interconnection emulation, and isnot supportedin combined deployments.

Huawei’sCloudEngine S12700E seriesis a high-end campus core switch series with the following highlights:

A. Control and switching separation: Improves scalability and flexibility

B. 4.8 Tbps/slot forwarding: Provides high-speed backbone for Wi-Fi 6/6E traffic

C. Redundancy design: Includes power supplies, fans, and control boards withcarrier-grade reliability (99.999%)

D. Ultra-large buffer & HQoS: Guarantees traffic for video conferencing, VoIP, and mission-critical services

All listed features are core strengths of this switch family.

Huawei'sWAN solution, particularly itsCloudWAN and SRv6-based architecture, is built on theIPv6 Enhancedtechnical system. This system integrates:

SRv6 (Segment Routing over IPv6)

IFIT (In-situ Flow Information Telemetry)

Network slicing and intelligent path computation

These technologies serve as the foundation forintelligent, high-performance WAN connectivity, forming the backbone forindustry digital transformation and intelligent applications.
