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

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'sWAN ISP solutionis designed for Internet Service Providers (ISPs) with the following key highlights:

A. 99% satisfaction of customer requirements: Huawei emphasizes its end-to-end solution capability and customer satisfaction, making the solution highly competitive and marketable.

B. BNG/CGN/SR/IPsec 4-in-1 design: This integration minimizes device deployment and simplifies O&M.

C. Compact design (1U/2U): Ideal for small PoPs (Points of Presence), improves space efficiency.

D. Energy-saving: Huawei routers adopt energy-saving technologies, helping reduceenergy consumption by up to 30%.

These features are documented in Huawei'sISP WAN Solution brochureand emphasized in HCSA-IP training.

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’sZTP (Zero-Touch Provisioning)function supportsmultiple automatic deployment modes, including:

C. USB-based deployment: Configuration file loaded onto device via USB drive

D. Registration query center-based deployment: Device queries a cloud-based registration center (iMaster NCE)

E. DHCP Option 148-based deployment: Device receives the controller address via DHCP option during boot

A. DCN deploymentandB. Email-based deploymentarenot supported or defined deployment typesin Huawei SD-WAN ZTP processes.

Huawei’sHiSecEngine firewallsuse a massive and frequently updatedsecurity signature database, which includes:

Application identification

Intrusion prevention rules

Virus and malware signature libraries

The latest-generationHiSecEngine USG firewallscanidentify over 20,000 applications, providinggranular control over network trafficand ensuring compliance, performance, and security.

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’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.
