Pass the Huawei HCSA-IP Network H19-301_V4.0 Questions and answers with ExamsMirror

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.

Huawei outlines theevolution of disaster recovery (DR)in data centers infour phases:

B. Single DC– No DR capability; all services reside in one data center.

C. Primary/Backup DC– Two data centers where one is primary and the other acts as a backup.

A. Two-site three-DC– One production site and two DR sites (or combinations).

D. Multi-site multi-DC– Advanced architecture with distributed data centers and cross-DR capabilities for resilience.

These are officially listed asDR evolution stagesin Huawei's multi-DC solution strategy.

In Huawei's data center network architecture, an underlay network refers to the physical infrastructure comprising switches, routers, and other network equipment (e.g., VAS devices), responsible for basic IP connectivity. This supports statement B.

The overlay network is logically built on top of the underlay and uses tunneling protocols such as VXLAN (MAC-in-UDP) to encapsulate Layer 2/Layer 3 service traffic. This encapsulation ensures transparent delivery of packets across IP underlays. This supports both C and D.

Statement A is incorrect: even when using an overlay, the underlay still requires routing protocols (like OSPF, BGP) or static routes to ensure IP reachability between VXLAN Tunnel Endpoints (VTEPs). Overlay tunnels ride on top of this IP connectivity.

Huawei’sNetEngine 8000 M14 and M8routers are designed to deliverindustry-leading performancefor backbone and metro scenarios. Theirkey highlightsinclude:

A. All-service integration: Supports IP, SRv6, VPN, multicast, and other services on a unified platform.

B. Compact footprint and redundancy: 7U/5U design with fully redundant architecture, suitable for space-constrained environments.

C. All-scenario 4-in-1 design: Integratescore, aggregation, DC gateway, and edge routingfunctionalities.

D. High performance: SupportsTbps-level throughput, ultra-low latency, and deterministic forwarding.

These highlights are outlined in Huawei’s product datasheets and WAN solution training materials.

Huawei’s wireless backhaul solution for rail transportation supports applications such as video surveillance, train-to-ground communication, and infotainment systems. However, it is explicitly stated in Huawei documentation that this solution is not designed for or certified to carry the safety-critical train signaling systems, which typically require dedicated and highly regulated communication networks.

Options A, C, and D are true and backed by Huawei’s performance claims:

Handover delay can reach as low as 30 ms using dual-link active-active design.

Video backhaul is maintained even at speeds up to 160 km/h.

Huawei’sNetEngine 8000 X seriesrouters offer these major highlights:

A. Support for large-scale L2/L3 services: Ideal for both enterprise and carrier networks

B. High-density 100GE ports: Suitable for high-bandwidth core and metro scenarios

C. Multi-service 5-in-1 design: SR, BNG, CGN, IPsec, and Security Architecture (SA)

E. Multi-platform convergence: Deployed in roles such as Provider Edge, Internet Gateway (IGW), and DC-Gateway (DC-GW)

D. 19.2T per slotis a specification forcore DC switches, not typically associated with theNetEngine 8000 X series, which has lower per-slot capacity.

The Huawei NetEngine AR651EW is a compact, all-in-one enterprise branch router that integrates:

LTE uplink

Wi-Fi 6 capability (802.11ax)

SD-WAN access

Security functions such as IPS and firewall

It is indeed Huawei's first edge router with built-in Wi-Fi 6 functionality, targeting small and medium-sized enterprise branches that require wireless access and SD-WAN features in a single device.

Huawei’sSD-WAN solutionprovides the following capabilities:

B. Intelligent traffic steering: Dynamically selects the best WAN link based on application SLA (e.g., latency, jitter).

C. Flexible overlay networking: Uses MPLS, Internet, and 4G/5G links in a hybrid WAN architecture.

D. Centralized management and WAN visualization: ThroughiMaster NCE, enabling centralized control and real-time monitoring.

A. Radio calibration on the Wi-Fiis a WLAN function andnot part of SD-WAN capabilities.

Huawei CloudFabric introduces a Network Digital Map (NDM) with AI-powered topology restoration capabilities.

This technology can:

Reconstruct full physical and logical topologies across multi-vendor and multi-cloud data centers.

Provide real-time visibility and mapping for O&M.

Simplify cross-DC operation and troubleshooting using AI and telemetry data.

Option A and B (“Lossless”) appear to be repeated distractors and irrelevant in this context.

Telemetry supports the technology but is not the direct implementation of topology visualization.

Huawei’sMini-BNG (Broadband Network Gateway)solution is designed forsmall/medium-scale deploymentscenarios and offers:

Small footprint(1U/2U chassis)

Independent deployment, with flexibility for edge networks

Low power consumption, making it cost-effective for remote PoPs

However, itdoes not have limited functions. Despite its compact size, it supportscomprehensive BNG capabilitiessuch as user management, IP address allocation, QoS, and security features — makingOption C (Limited functions) incorrect.
