The HCSA-Presales-IP Network V4.0 (H19-301_V4.0)

Huawei’s CloudEngine S6780-H is a high-performance fixed switch that:

Offers up to 128 × 25GE ports or 64 × 50GE ports in a compact 1U form factor.

Is recognized as the industry's highest-density fixed campus switch.

Supports powerful features such as VXLAN, telemetry, and flexible NetStream.

Other switches listed:

CloudEngine S8700 is a modular chassis-based switch.

CloudEngine S16700 does not exist (appears to be a typographical error).

CloudEngine S6750-S is high-performance but lower in density than the S6780-H.

NetEngine 8000 series access routers , particularly those designed for edge and access scenarios , support:

Wide temperature operation from -40°C to +65°C

Fanless or rugged designs for harsh environments

Deployment in outdoor cabinets and remote edge locations

This ruggedization supports reliable operation in extreme field conditions.

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.

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 Wi-Fi Shield technology is designed to enhance WLAN security and includes features such as:

Unauthorized terminal detection and suppression

Data encryption and integrity protection

Air interface behavior analysis to block rogue APs or attackers

Contrary to the statement, Wi-Fi Shield prevents unauthorized terminals from accessing or parsing any data , making the correct answer 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’s intelligent cloud-network solution involves the convergence of multiple product lines to build Net5.5G-ready infrastructure :

A. CloudEngine : Core for data center and campus switching

B. NetEngine : High-performance routing platform for WAN and core network scenarios

C. HiSecEngine : Security product line for integrated and intelligent security services

D. AirEngine : Wireless access product line, including Wi-Fi 6/7

All four products are pillars in Huawei’s strategy to evolve toward ubiquitous, intelligent, high-speed IP connectivity under Net5.5G .

An AI computing network focuses on interconnecting large numbers of servers and AI accelerators to:

Scale the cluster size efficiently ( A )

Ensure cluster-wide efficiency in data exchange and training convergence ( B )

Maintain high availability of the overall AI computing system ( C )

D. Single-card computing power refers to individual GPU/AI chip capabilities , which is a hardware-level concern , not a network-level performance factor .

Huawei Hybrid Cable 2.0 integrates power lines and optical fibers into a single cable. It supports PoE+ (IEEE 802.3at) and extends the PoE+ power supply distance up to 600 meters without using additional power modules.

This feature is especially valuable for outdoor AP deployments where conventional Ethernet cabling distances are limited (typically up to 100 m). Hybrid Cable 2.0 simplifies cabling and reduces infrastructure costs in remote deployment scenarios.
