Huawei’s financial branch case study cites:

•High private line costs – SD-WAN reduces costs (US$500 vs. US$50).

•Manual rollout delays – SD-WAN automates provisioning, cutting weeks to minutes.

•Trend and budget – Not primary drivers per the success story.

Wi-Fi 7 (802.11be) supports:

•Immersive education – VR/AR with low latency.

•Hybrid work – Multi-app concurrency with high throughput.

•4K conferencing – Stable, high-bandwidth video.

•Production automation – Real-time IoT and robotics control.

These exceed Wi-Fi 6 capabilities, as per Huawei’s Wi-Fi 7 documentation.

Comprehensive and Detailed in Depth Explanation:WAN upgrades are driven by evolving enterprise needs, as outlined in the HCSA-Sales-IP Network V6.0:

Deteriorated connection performance (A):Aging WAN infrastructure struggles with latency and packet loss, necessitating upgrades.

Complex O&M (B):Traditional WANs require manual management, driving the shift to SD-WAN for simplification.

Insufficient bandwidth (C):Cloud and application growth demand higher capacity.

NetEngine capabilities:

•100GE/400GE convergence – High-speed interfaces.

•Visualized O&M – Network Digital Map integration.

•SRv6/Slicing services – Advanced traffic engineering.

•Ultra-stable reliability – Redundancy features.

NetEngine routers (e.g., AR, 8000 series):

•Intelligent O&M – Via iMaster NCE.

•Large capacity – High forwarding rates (e.g., 19.2 Tbps).

•Full services – SD-WAN, VPN, etc.

•High reliability – Redundant designs.

The NetEngine AR series (access routers) targets multiple industries, as outlined in the HCSA-Sales-IP Network V6.0:

Large enterprise: For branch connectivity and SD-WAN.

Government: For secure e-government WANs.

Finance: For reliable, high-security branch networks.

Catering & retail: For distributed retail SD-WAN solutions.

CloudFabric highlights:

•40% lower energy consumption – Energy-efficient design.

•Ultra-stable reliability – Redundancy and fault tolerance.

•Ultra-powerful performance – High throughput (e.g., 400GE).

•Ultra-intelligent O&M – AI-driven management via iMaster NCE.

The HCSA-Sales-IP Network V6.0 outlines NetEngine routers’ sales strategies across various markets:

A: Targets digital transformation in developing regions with cloud-network integration.

B: Focuses on power/transport with specific features like 50 ms switchover and network slicing.

C: Addresses OTT needs with optimized cloud backbone solutions.

D: Emphasizes infrastructure projects like broadband and e-government.

E: Offers mini-BRAS for IAPs, enhancing subscriber capacity.

In multi-architecture computing (AI, HPC, general-purpose):

•O&M efficiency – Complex management across architectures.

•Security and reliability – Higher stakes for uptime and protection.

•Connection performance – Demands for low latency and high throughput.

•Increasing end users – Not a DCN-specific challenge; focus is on infrastructure.

Huawei outlines these challenges in campus network construction:

•Complex network architecture, difficult to integrate dedicated networks – Legacy and new systems create integration issues.

•The number of networks increases sharply, causing high security risks – More endpoints and networks elevate vulnerabilities.

•There are challenges in ensuring O&M efficiency – Manual operations struggle to keep up with scale and complexity.

•Gigabit networks cannot meet new application requirements – While a concern, Huawei emphasizes 10 Gbps upgrades (not gigabit limitations) as the solution, making this less of a highlighted challenge.

In the all-intelligence era, data communication networks face evolving demands driven by digital transformation, AI integration, and intelligent connectivity. Huawei’s HCSA-Sales-IP Network documentation highlights these new requirements:

•Network security: threat elimination at anywhere – With cyber threats becoming ubiquitous, networks must proactively eliminate risks at all points, aligning with Huawei’s HiSec security solutions.

•DCN: AI and cloud computing – Data Center Networks (DCNs) must support AI-driven workloads and cloud computing scalability, as seen in Huawei’s CloudEngine series.

•WAN: mission-critical service connectivity – Wide Area Networks (WANs) need to ensure uninterrupted connectivity for critical services, a key feature of Huawei’s NetEngine routers and SD-WAN solutions.

•Campus network: fully-wireless and video-oriented – Campus networks are shifting toward fully wireless architectures (e.g., Wi-Fi 7) and must support high-bandwidth video applications, as emphasized in Huawei’s CloudCampus solution.

These demands reflect the transition to intelligent, secure, and high-performance networks, as outlined in Huawei’s official training materials.

Huawei’s Intelligent Cloud-Network Solution is a comprehensive framework designed to address modern networking needs across various scenarios, integrating cloud and network technologies.According to HCSA-Sales-IP Network V6.0, this solution comprises three core components: CloudCampus, CloudWAN, and CloudFabric. CloudCampus focuses on campus network scenarios, delivering intelligent connectivity and management for enterprises, educational institutions, and similar environments. CloudWAN targets wide-area network optimization, providing high-performance connectivity across geographically dispersed locations. CloudFabric is tailored for data center networks, ensuring high-speed, scalable, and reliable cloud computing infrastructure. HiSec, while a critical part of Huawei’s security portfolio, is not a core component of the Intelligent Cloud-Network Solution; it is a security solution focused on threat protection rather than network connectivity. IdeaHub, an intelligent collaboration endpoint, falls under Huawei’s smart office portfolio, not the datacom network solution. Thus, the correct answers are A (CloudCampus), B (CloudWAN), and C (CloudFabric).References: HCSA-Sales-IP Network V6.0, Chapter on Intelligent Cloud-Network Solution.
