Huawei’s USG firewalls, per HCSA-Sales-IP Network V6.0, are deployed in data center networks (A) for protecting core infrastructure, campus networks (B) for enterprise security, and branch networks (D) for distributed sites. Virtual machines (VM, C) are not a deployment scenario for USG, as it is a physical or virtualized appliance, not specifically tied to VM hosting. Thus, A, B, and D are correct. References: HCSA-Sales-IP Network V6.0, USG Firewall Deployment Scenarios.

Huawei targets:

• Oil/energy – HPC for mining.

• Education – University and regional DCNs.

• Government – E-government and national DCNs.

• Large enterprise EDC – Enterprise data centers.

• Finance – Banking DCNs.

• Aviation – Less emphasized in Huawei’s primary DCN sales focus.

The HiSec SASE (Secure Access Service Edge) solution, per HCSA-Sales-IP Network V6.0, integrates SecoManager (A) for security management, HiSecEngine AI firewall (B) for advanced threat protection, and HiSec Endpoint (E) for endpoint security. QiankunOP (C) and iMaster NCE-Campus (D) are not part of SASE; QiankunOP is unrelated, and NCE-Campus is a network management tool. Thus, A, B, and E are correct.

Huawei’s Intelligent Cloud-Network Solution is a comprehensive framework designed to address modern networking challenges across data centers, wide-area networks (WANs), and campus networks. According to the HCSA-Sales-IP Network V6.0 documentation, this solution comprises three key components:

CloudFabric: Focused on data center networking, it provides intelligent, automated, and high-performance network solutions for cloud data centers.

CloudWAN: Targets wide-area network optimization, offering intelligent routing, traffic optimization, and network visualization for distributed enterprises.

CloudCampus: Designed for campus network scenarios, it delivers intelligent, reliable, and scalable Wi-Fi and wired network solutions.

HiSec: While part of Huawei’s security portfolio (e.g., HiSec firewalls), it is not categorized under the Intelligent Cloud-Network Solution; it focuses on network security rather than core networking.

• Modular series allow hardware expansion (e.g., additional ports):

o CloudEngine S12700E, S16700, S8700, S7700 – All support modular designs.

• CloudEngine S5735-L – A fixed-configuration switch, not modular, designed for simpler deployments.

Huawei’s documentation distinguishes fixed vs. modular switches, confirming S5735-L as non-modular.

Huawei’s Wi-Fi 7 introduces Wi-Fi Shield, a proprietary security feature:

• Ensures only authorized devices can decrypt and parse data signals.

• Prevents eavesdropping by making data invisible to unauthorized users through advanced encryption and signal manipulation.

This technology enhances security in wireless networks, a key selling point of Huawei’s AirEngine Wi-Fi 7 APs, as detailed in official documentation.

Huawei security products, per HCSA-Sales-IP Network V6.0, focus on network and IT security scenarios: data center network security (B), cloud security (C), and campus network security (D). Personal safety (A), such as physical security, is not a major scenario for these products, which are IT-centric. Thus, A is the correct answer.

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.

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.
