Huawei defines thecore technical fields of campus networksas:

WLAN (Wireless LAN)

Wired LAN (Switching Network)

SD-WAN, when used forbranch interconnectionwithin enterprise campuses

WAN, on the other hand, is a broadercarrier-class infrastructureandnot specifically categorized as a campus network technology. It refers to long-distance, backbone, or ISP-level connectivity beyond the scope of typical enterprise campus deployments.

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.

Enablescross-cloud, multi-vendor interoperability

Supportsminute-level deployment of cross-cloud services

Works withAscend AI chips and platformsto supportAI-native networking, includingplug-and-play and same-day delivery

These capabilities are officially highlighted in Huawei’s DCN solution documentation.

Huawei SD-WAN providesflexible Internet access optionsbased on enterprise architecture and policies:

A. Centralized Internet access: Internet traffic from branches is sent to HQ or data center before being forwarded to the Internet

C. Local Internet access: Internet traffic is directly forwarded at the branch (also called DIA — Direct Internet Access)

D. Hybrid Internet access: Combines centralized and local Internet access based on application type or policy

B. Remote Internet accessisnot a standard Huawei-defined modein this context.

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'santi-DDoS solutionconsists ofthree core components:

B. Management Center– Handles centralized policy configuration, resource scheduling, and coordination across devices.

C. Detection Center– Performs real-time traffic analysis, identifies abnormal patterns, and triggers alarms.

D. Cleaning Center– Executes traffic scrubbing to remove malicious packets and forward clean traffic to the intended destination.

A. Maintenance centeris not a defined component in Huawei’s anti-DDoS architecture.

Huawei’s Data Center Network Solution, part of the CloudFabric architecture, highlights four core capabilities:

A. Ultra-stable reliability — Ensures 99.999% availability, delivering sustainable computing and fault-tolerant network infrastructure across various failure scenarios.

B. One network for diverse computing — Seamlessly supports diverse workloads (e.g., HPC, AI, traditional computing) with non-blocking fabric and intelligent forwarding, ensuring zero interruptions.

C. One map for intelligent O&M — Uses Huawei’s iMaster NCE to provide full-network visibility, proactive alarms, and AI-driven assurance, addressing O&M concerns.

D. One platform for simplified deployment — Enables centralized automation with zero-touch provisioning, minimizing configuration errors.

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 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.

Segment Routing (SR) introduces a source routing model where the source node defines the path that packets take through the network by imposing a list of segments (instructions).

SR is aligned with SDN principles — the network is programmable and flexible.

SR does NOT depend on LDP or RSVP. Instead, SR uses extensions to IGP (OSPF or IS-IS) or BGP to distribute segment information.

SR simplifies the control plane by reducing the number of protocols needed for label distribution.

SR can work with or without a controller — the controller enhances path computation but is not mandatory for basic SR operation.

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’s WAN solution for thefinancial industryis tailored to meet requirements such aslow latency, high reliability, security, and fast deployment. It is used in:

A. Integrated information bearer network: Connects multiple financial systems and services.

C. Interconnection and load balancing between backbone clouds: Supportsmulti-cloud hybrid deployments.

D. Agile cloud migration of bank branches: Enables secure, automated SD-WAN-based migration to cloud services.

B. Vehicle-ground communication networkisspecific to the transportation or railway industry, not financial services.

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'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.

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

Unified managementof bothLAN and WAN devices

Real-time traffic monitoringwith visibility down to application and user levels

AI-basedfault diagnosis and O&M automation

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