Huawei's CloudWAN 3.0 solution is a next-generation WAN architecture designed to address the challenges of digital transformation and cloud adoption. The key highlights of this solution include:

One-network wide connection : CloudWAN 3.0 enables seamless connectivity across multiple sites, integrating various access technologies (e.g., MPLS, SD-WAN, and PON) into a unified network. This ensures efficient resource utilization and simplifies network management.

One-fiber multipurpose transport : This feature allows a single fiber to carry multiple services, such as Internet, voice, video, and private line services. It significantly reduces infrastructure costs and improves operational efficiency.

One-hop cloud access : CloudWAN 3.0 provides direct, low-latency access to cloud services through optimized routing. This enhances user experience and supports real-time applications like video conferencing and online collaboration.

While "one-click maintenance" and "one-click fast scheduling" are valuable features in network management, they are not explicitly highlighted as part of the CloudWAN 3.0 solution in official Huawei documentation.

The Huawei CloudEngine S8700 series switches are designed for enterprise campus networks and aggregation layers, offering advanced hardware features that ensure high performance, scalability, and reliability. Below is an explanation of each option:

Cards with ultra-high-density GE optical/GE electrical/10GE optical ports : The S8700 supports high-density interfaces, including Gigabit Ethernet (GE) and 10 Gigabit Ethernet (10GE) ports, making it suitable for large-scale campus networks.

Ultra-high PoE++ output capability, supporting ultra-long-distance high-performance PoE transmission : The switch provides Power over Ethernet (PoE++) support, delivering up to 90W per port. This capability is ideal for powering devices like IP cameras, wireless access points, and IoT devices over long distances.

Service subcards are integrated on the main control board panel, separating the forwarding plane from the control plane and enriching port combinations : This design enhances modularity and flexibility, allowing users to customize port configurations based on their specific requirements.

The main control boards work in 1:1 backup mode. When a main control board is removed and then installed, no packet loss occurs and the performance does not deteriorate : The S8700 ensures high availability through redundant main control boards. This feature guarantees uninterrupted operation even during maintenance or failures.

All four options accurately describe the hardware characteristics of the S8700, making them all correct.

MACsec (Media Access Control Security) is a Layer 2 encryption protocol that ensures secure communication between devices in a network. It provides data confidentiality, integrity, and replay protection at the Ethernet layer. Below is an analysis of each option:

NetEngine 8000 MIA : This model supports MACsec, making it suitable for secure WAN and data center interconnections.

NetEngine 8000 F1A : This model also supports MACsec, enabling secure high-speed connections.

NetEngine 8000 MIC : The MIC series does not support MACsec, as it is primarily designed for modular interfaces without encryption capabilities.

NetEngine 8000 M6 : This model supports MACsec, ensuring secure communication for enterprise networks.

Thus, the correct answers are A , B , and D .

Huawei Wi-Fi 6 solutionseliminate signal blind spotsusing their"Unique Dynamic-Zoom Smart Antenna"technology.

(C) True – Dynamic-Zoom Smart Antenna:

Automatically adjustsantenna beamformingbased on terminal location.

Improves signal coverage and reduces interference in complex environments.

Ensuresseamless roamingacross APs withstronger signal stability.

Other options:

(A) DFA (False): DFA optimizesfrequency selectionbut does not eliminate signal blind spots.

(B) AI Roaming Algorithm (False): Enhanceshandover between APs, but does not directly eliminate blind spots.

(D) 6 GHz Band (False): Providesmore spectrum, but coverage depends on the AP's antenna design.

The Huawei NetEngine 8000 M6 series routers are designed for robust performance in various environmental conditions. For models with DC power supply , the normal operating temperature range is -20°C to +65°C .

Below is an explanation of the other options:

0°C to +45°C : This range is too narrow and does not reflect the router's actual capabilities.

-40°C to +65°C : This range applies to extreme environments and is typically associated with AC-powered models or specialized variants.

-20°C to +45°C : This range is incorrect for DC-powered models, as the upper limit is lower than the actual specification.

Thus, the correct answer is B , as the operating temperature for DC-powered NetEngine 8000 M6 routers is -20°C to +65°C .
