Huawei’s ZTP (Zero-Touch Provisioning) function supports multiple 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 deployment and B. Email-based deployment are not supported or defined deployment types in Huawei SD-WAN ZTP processes.

In Huawei firewall deployments (such as USG6000 series), using a single firewall at the network egress creates a single point of failure (SPOF).

To improve reliability, Huawei supports firewall stacking technology, called FW-Stack.

In a firewall stack, multiple firewalls form a single logical device.

Advantages of firewall stacking include:

Unified management: Only the stack system is configured and managed, not individual members.

Seamless failover: If a member firewall fails, services continue on other members.

Increased throughput: Aggregate performance of multiple firewalls.

This setup greatly enhances service continuity and improves network reliability without needing complex configuration across devices.

Huawei’s High-Quality 10 Gbps Campus Network Solution is experience-centric and delivers upgrades in three key areas:

A. Wireless experience upgrade — Enhanced via intelligent radio calibration, Wi-Fi 7 AirEngine APs, and anti-interference tech.

C. O & M experience upgrade — Achieved through AI-based O & M and one map for unified visualization via iMaster NCE-Campus.

D. Application experience upgrade — Uses application awareness and traffic steering to ensure consistent performance.

B is incorrect: while O & M costs are optimized, this is not formally listed as one of the “three types of experience upgrade.”

iMaster NCE-Campus is Huawei’s intelligent network management and control system for enterprise networks. It supports:

Unified management of both LAN and WAN devices

Real-time traffic monitoring with visibility down to application and user levels

AI-based fault diagnosis and O & M automation

These capabilities reduce manual effort and improve efficiency in daily network operations and troubleshooting.

The Solution Configuration Tool (SCT) supports:

Viewing products (A)

Comparing products (C)

Configuring product components (D)

However, B. Ordering the products directly is not available in SCT. SCT is a configuration and solution design tool , not a purchasing platform. Orders must be placed through authorized Huawei sales channels or partner platforms.

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.

WLAN (Wireless Local Area Network) specifically refers to wireless networks based on the IEEE 802.11 standards , which are commonly known as Wi-Fi . While infrared, Bluetooth, and ZigBee are also wireless technologies, they are not part of WLAN :

Wi-Fi (802.11) = WLAN

Bluetooth, ZigBee, Infrared = PAN or IoT technologies, not WLAN

Thus, grouping all these under WLAN is incorrect , making the correct answer False .

Huawei's automatic network migration solution when upgrading from a legacy N7-5-2 network to an SDN-based CloudFabric network involves the following key steps , as outlined in the CloudFabric documentation:

A. Gateway migration : Move north-south traffic gateways from legacy to new fabric for optimized traffic flow.

B. Live network analysis : Import configurations and traffic patterns from the existing network into iMaster NCE.

C. Layer 2 interconnection : Create Layer 2 links between old and new networks for seamless traffic bridging.

D. Service migration : Gradually migrate VMs and workloads using scheduling tools without downtime.

All steps are necessary to ensure smooth migration without service disruption.

High throughput and carrier-grade reliability

This device is optimized for enterprise WAN edge deployments requiring performance and integration.

The Huawei NetEngine AR8700-8 is a high-performance, high-reliability converged gateway designed for complex WAN edge scenarios such as:

Enterprise headquarters

Financial institutions or headquarters

Large campuses

It provides high forwarding performance, integrated SD-WAN capabilities, intelligent traffic steering, application identification, and security features (e.g., built-in firewall, IPS, etc.).

Refueling and retail headquarters typically require smaller, more compact edge devices (such as AR600 or AR6100 series), rather than a full-scale high-performance router like the AR8700.

Huawei SecoManager is the centralized management platform for Huawei security devices, including anti-DDoS appliances. It is used for:

Defense policy configuration

Dynamic scheduling of scrubbing resources

Device management

Report and log visualization for threat analysis

The other options serve different roles:

Qiankun-OP : Huawei's cloud-based SOC platform

HiSec Insight : Used for security situation awareness

DireHunter : Threat hunting and deep analysis tool

As per Huawei’s official security management product specifications, SecoManager supports centralized management of up to 8000 security devices , including firewalls, anti-DDoS, IPS, and other security appliances. This scalability makes it suitable for large enterprises and carriers.

WPA3 (Wi-Fi Protected Access 3) is the latest Wi-Fi security standard defined by the Wi-Fi Alliance. It enhances security compared to WPA2 by offering:

Mandatory use of SAE (Simultaneous Authentication of Equals), which replaces the less secure PSK (Pre-Shared Key).

Protection against dictionary attacks.

Enhanced encryption methods.

WPA3-Enterprise uses a 192-bit minimum-strength security suite, including 256-bit GCM encryption and 384-bit ECC key exchange, but the base definition references a minimum of 192-bit equivalent security strength.

This significantly enhances the robustness of wireless encryption and aligns with government and enterprise-grade security requirements.

Huawei CloudEngine S16700 is a next-gen modular core switch for large campus networks. Its key features include:

Ultra-large capacity: Each slot supports up to 4.8 Tbps throughput and can be scaled up to 14.4 Tbps (Option A — True)

Backplane-free orthogonal architecture: Significantly enhances switching efficiency and simplifies cooling (Option B — True)

M-LAG support: Enables in-service software upgrades and link-level redundancy (Option D — True)

However, while dual-input power supplies are standard, this alone is not highlighted as an "ultra-high reliability" feature in Huawei documentation (Option C — Not a core highlight).

Huawei AirEngine APs with the leader AP feature are capable of managing Fit APs in small-scale or branch networks . The supported forwarding modes include:

A. Tunnel forwarding : Traffic is encapsulated and sent to the gateway (leader AP or AC)

B. Direct forwarding : Traffic exits directly at the AP to reduce latency

Bridge forwarding and route forwarding are not standard forwarding modes in this context. Bridge mode generally applies to Layer 2 switching, and route forwarding pertains to Layer 3 routers, not WLAN forwarding at the AP level.

The CloudEngine S8700 is a modular switch designed for high-performance, high-visibility campus networks.

Huawei equips this series with an “Experience Assurance Card,” which enables:

Real-time traffic identification

Application-level statistics collection

In-path traffic analysis for performance bottlenecks

This hardware is central to the centralized experience assurance solution offered in the High-Quality 10 Gbps Campus Network.

In a WAC (Wireless Access Controller) + Fit AP architecture:

A, B, and C are accurate descriptions.

D is false : The AC (WAC) and Fit APs do not use SNMP for communication . Instead, they communicate using CAPWAP (Control And Provisioning of Wireless Access Points) protocol, which supports control, management, and data encapsulation between ACs and APs.

SNMP is used for network management and monitoring but is not the protocol for AC-to-AP communication in WLAN scenarios.

Huawei's Xinghe Multi-DC Network Solution provides three levels of ultra-high reliability :

A. Device-level high reliability : Achieves zero data loss through component redundancy

C. Network-level high reliability : Ensures no service disruption even during faults or upgrades

D. Link-level high reliability : Uses intelligent rerouting to prevent traffic interruption

B. High O & M reliability with hour-level fault locating is not listed as a core reliability tier; Huawei emphasizes minute-level AI-driven fault detection instead.

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.

M-LAG (Multi-Chassis Link Aggregation Group) is a technology that allows link aggregation across two physical devices , enabling:

Active-active system deployment

Traffic load balancing

Backup protection without relying on stacking

Unlike Eth-Trunk , which aggregates links on the same device, M-LAG extends this functionality across multiple devices.

LLDP is a discovery protocol and Stack refers to virtual device technology, not specifically inter-device link aggregation.

Huawei’s anti-DDoS solution supports multiple deployment scenarios depending on the network design and customer needs:

A. Flow inspection and dynamic traffic diversion : Monitors traffic flows and dynamically redirects suspicious traffic to the cleaning center.

B. In-line deployment : Anti-DDoS device sits directly in the data path, filtering traffic in real time.

C. Off-path deployment and static traffic diversion : Traffic is redirected to scrubbing centers using fixed rules.

D. Per-packet inspection and dynamic traffic diversion is not a standard Huawei anti-DDoS deployment term , and Huawei’s solution focuses on flow-level inspection , not deep per-packet analysis in this context.

Among the options:

B. SecoManager is the controller responsible for centralized management, orchestration, and policy control .

The following are not controllers :

A. HiSec Insight : Provides security visibility, analysis, and AI-based threat detection .

C. Qiankun-OP : A cloud-based security operations platform (SOC) , focused on situational awareness.

D. FireHunter : A sandbox-based APT detection engine , part of the threat detection infrastructure.

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.

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.

Huawei’s Xinghe Intelligent Ultra-Resilient Multi-DC Network Solution offers the following four key benefits :

A. Three-level reliability : Ensures network-level, device-level, and link-level fault tolerance with 99.999% availability .

B. Intelligent O & M : Provides always-online services with proactive health monitoring and fault prediction.

C. Network fault locating in minutes : Uses AI and telemetry to pinpoint faults in real time.

D. Unified deployment : Reduces provisioning time from days to minutes through automation.

These features make the solution ideal for large-scale and critical DC environments.

The Huawei CloudEngine S6750-S is a high-performance all-optical switch in the fixed switch series, suitable for 10 Gbps campus networks.

It includes advanced features such as:

VXLAN and network slicing (Option B — Correct)

Real-time telemetry and intelligent O & M via iMaster NCE (Option C — Correct)

Native WAC capabilities for wireless and wired convergence (Option E — Correct)

However, MACsec (IEEE 802.1AE) is not supported on all ports by default — support is partial or dependent on model/sub-model. Hence, Option D is false.

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.

Huawei defines the WLAN network lifecycle using a comprehensive 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 the WLAN planning and deployment methodology using tools like SCT and iMaster NCE-Campus .

The Huawei CloudEngine S8700 series supports cluster-based active-active architecture , offering:

50 ms-level failover

Hot patching and ISSU (In-Service Software Upgrade)

Service continuity during upgrade and fault scenarios

Unlike VRRP , which is used for gateway redundancy, or M-LAG and stack , which are link or port-level mechanisms, the cluster solution provides full-device-level failover and operational continuity .
