Huawei H19-301_V4.0 - HCSA-Presales-IP Network V4.0

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’s NetEngine WAN solution offers:

Full interface rate support from 64 kbps (legacy TDM) up to 400 Gbps for ultra-broadband scenarios.

Converged access, including wired and wireless for any application environment.

SRv6 (Segment Routing over IPv6) for simplified configuration and intelligent path computation.

One-click service deployment via mobile phone and cloud-based orchestration through iMaster NCE.

However, 800 Gbps interfaces are not yet part of Huawei's mainstream WAN product line. Thus, option C is inaccurate.

In Huawei'sUSB-based SD-WAN deployment method, thecommon stepsinclude:

D. Plan sites and configure devices and the network: This is done first in the iMaster NCE system.

B. Generate a deployment file: After planning, the system generates the configuration file.

C. Perform onsite ZTP deployment: This file is copied to a USB drive and plugged into the device for ZTP.

A. Import initial configuration files in batchesis not part of USB-based deployment but applies tobulk deploymentmethods using the network or controller directly.

TheNetEngine AR8100series is Huawei’sultra-large-capacity WAN gatewayplatform used inSD-WAN hub nodes. According to Huawei’s SD-WAN solution architecture:

NetEngine AR8100 routerscansupport up to 2000 SD-WAN sites, acting as acentral controller or hub nodein large enterprise WAN deployments.

This is a key highlight of the AR8100’s scalability and its role inlarge-scale SD-WAN networks.

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’sintelligent cloud-network solutioninvolves the convergence of multiple product lines to buildNet5.5G-ready infrastructure:

A. CloudEngine: Core for data center and campus switching

B. NetEngine: High-performance routing platform for WAN and core network scenarios

C. HiSecEngine: Security product line for integrated and intelligent security services

D. AirEngine: Wireless access product line, including Wi-Fi 6/7

All four products are pillars in Huawei’s strategy to evolve towardubiquitous, intelligent, high-speed IP connectivityunderNet5.5G.

TheHuawei SD-WAN solutionprovidesfour main highlights, all of which are options listed in this

A. One network to multiple clouds, on-demand interconnection: Seamless cloud access through intelligent link selection.

B. Large-scale networking, secure and reliable: Supports extensive deployment across thousands of branches with encrypted tunnels.

C. Integrated management, control, and analysis, intelligent O&M: UsesiMaster NCEfor unified control and AI-powered O&M.

D. Intelligent traffic steering, superior experience: Dynamically selects the best path based on application type and network performance.

These highlights are found in official Huawei solution documentation and are emphasized in the HCSA-IP training.

Huawei’sWi-Fi Shield technologyis designed toenhance WLAN securityand includes features such as:

Unauthorized terminal detection and suppression

Data encryption and integrity protection

Air interface behavior analysisto block rogue APs or attackers

Contrary to the statement,Wi-Fi Shield prevents unauthorized terminals from accessing or parsing any data, making the correct answerFalse.

VXLAN (Virtual Extensible LAN) technology uses MAC-in-UDP encapsulation to extend Layer 2 networks over Layer 3 networks.

It encapsulates the original Ethernet frame into a UDP packet, allowing it to traverse an IP network.

VXLAN decouples the logical network from the underlying physical network, meaning MAC addresses of VMs are encapsulated and do not affect the routing of packets across the IP underlay.

VXLAN supports large-scale network expansion with up to 16 million VXLAN segments (compared to 4096 VLANs).

Furthermore, because VXLAN uses a routed underlay network, VM migration is not restricted by Layer 2 boundaries.

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.
