TheNetEngine 8000 M14 and M8aremodular high-performance WAN routers. Theirdepth is significantly more than 220 mm. For example:

NetEngine 8000 M8: Approx.600 mmdepth

NetEngine 8000 M14: Larger chassis — deeper than600 mm

A depth of220 mmwould be typical of very compact devices (e.g., small access routers), not these high-capacity modular systems.

Huawei's VIP user assurance solution, introduced in their Wi-Fi 6 and Wi-Fi 7 AirEngine APs, includes two key technologies:

VIP FastPass: Identifies and prioritizes VIP users at the air interface level to ensure their packets are transmitted first.

Per-Packet Power Control (PPC): Dynamically adjusts the transmit power for each packet to improve signal quality and reduce interference for VIP users.

These technologies increase both reliability and available bandwidth for high-value users and critical applications.

Huawei’s iMaster NCE and digital intelligent O&M strategy focus on transforming traditional KPI-based monitoring into user- and application-centered assurance models.

A. VIP user experience: Priority monitoring and alerting for key users.

B. Terminal experience: Insights into access quality, authentication failures, and connection drops.

C. Wireless experience: Coverage maps, roaming statistics, interference detection.

D. Application experience: Ensures performance for latency-sensitive apps like voice/video through QoS and deep packet inspection.

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.

QoS (Quality of Service)is thetechnology used to prioritize and guarantee bandwidthand latency performance forVIP users and mission-critical applications. It enables:

Traffic classification and prioritization

Bandwidth guarantees and rate limiting

Low latency paths for real-time services

A. IPsec VPN– Provides secure tunneling, not traffic prioritization

B. SSH and C. SSL– Offerencryptionfor secure access, but not performance assurance

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.

Huawei’sAR6700Vis avirtual router(vCPE) that supports deployment onmainstream public clouds, including:

Huawei Cloud

Microsoft Azure

AWS Cloud

However, as per the latest support matrix,Baidu Cloudisnot listed as a supported platformfor AR6700V deployment.

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.

TheHuawei NetEngine AR6710-L14T2X4is a high-performance enterprise gateway router thatsupports more than just SD-WAN and switch convergence. It also supports:

WAN optimization

SRv6

Application-level routing

Integrated security (including firewall and IPS capabilities)

Wireless access and VPN features

This router is designed forconverged services,not limitedto only SD-WAN and switches.

Huawei's Free Mobility Solution decouples user identity from IP address and physical location.

Regardless of where a user accesses the campus network (wired or wireless), the same network access policies (such as ACLs, QoS, VLAN assignments) are dynamically applied based on the user identity.

Administrators only need to define access policies between user groups and server resources based on logical relationships (e.g., HR can access payroll servers) without worrying about IP addressing or user location.

This mechanism uses technologies like VXLAN-based campus network combined with policy association via iMaster NCE-Campus.

A typicaldata center networkconnects core computing and storage infrastructure, including:

B. Server

C. High-performance AI server

D. Storage devices (NAS, SAN, etc.)

A. Camerais not a core data center component; it may be connected via separatesurveillance or edge networks, not the maindata center network fabric.

Huawei identifies the transition fromdigital to intelligent transformationas a phase whereenterprise data communication networksface severalnew challenges, such as:

High-density wireless connectivity demands

Heavy use of video-based and real-time applications

The exponential growth of AI computing power

Critical workloads moving to public and hybrid cloud platforms

Ever-evolving cybersecurity threats

These are outlined in the context of buildingNet5.5G-ready networksto address such demands.

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.

The wireless throughput of an AP is primarily influenced by physical layer factors such as:

A. Spatial Streams: More spatial streams allow more simultaneous data channels.

B. Frequency Bandwidth: Wider channels (e.g., 40 MHz, 80 MHz, or 160 MHz) allow more data to be transmitted.

D. SNR: Higher signal-to-noise ratio leads to higher modulation levels and throughput.

Option C (CPU performance) affects the system's ability to process traffic at the application or system level, but not the physical-layer wireless rate. CPU performance may affect total packet forwarding but is not directly a factor in wireless transmission rate.

Huawei’s 10 Gbps campus network solution is described as “experience-centric,” aiming to:

Improve wireless performance with Wi-Fi 7 and interference mitigation (Wireless experience).

Enable AI-driven operations and centralized visualization (O&M experience).

Ensure deterministic application delivery via traffic identification and smart QoS (Application experience).

This triad forms the core of Huawei’s experience-based networking model for education, healthcare, finance, and enterprise sectors.

A higher antenna gain indicates a narrower beamwidth and greater signal directivity—not necessarily wider coverage. While high-gain antennas can transmit stronger signals in a specific direction, they reduce coverage in other directions. In WLAN design, especially for omnidirectional coverage in campus scenarios, antenna selection is based on application requirements rather than simply preferring higher gain.

Huawei emphasizes that antenna gain must comply with local regulations and should match deployment scenarios (e.g., indoor omnidirectional vs outdoor long-range). Excessively high gain may result in coverage holes or regulatory non-compliance.

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

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.

Huawei's Intelligent Converged Scheduling technology for campus WLAN:

Uses MU-MIMO (Multi-User Multiple-Input Multiple-Output) to enable simultaneous communication with multiple clients.

Integrates OFDMA (Orthogonal Frequency Division Multiple Access) to allocate subcarriers efficiently among users.

These two technologies are cornerstones of Wi-Fi 6 and Wi-Fi 7 intelligent scheduling.

MRU-MIMO is not a valid standard.

SRv6 is a WAN routing and forwarding technology unrelated to WLAN scheduling.
