The Huawei CloudEngine 6881 is a high-performance data center switch that supports both stacking and M-LAG (Multichassis Link Aggregation Group) technologies. M-LAG is a key feature for increasing redundancy and reliability in leaf-spine architectures by enabling two switches to act as a single logical device for link aggregation.

The claim that the CE6881 does not support M-LAG is FALSE , as this model fully supports M-LAG to enhance network availability and fault tolerance.

Comprehensive and Detailed in Depth Explanation:Huawei IoT APs support multiple methods for integrating IoT modules or functionalities:

Option A: The USB interface allows external IoT modules to be connected to the AP, enabling flexible expansion.

Option B: Some Huawei IoT APs come with built-in IoT chips, providing native support for IoT protocols like RFID and Bluetooth.

Option C: The PCIe interface is another method for integrating IoT modules, offering high-speed connectivity for advanced IoT applications.

Option D: The PoE out port is used to power external devices but does not directly integrate IoT functionality.

These integration methods ensure that Huawei IoT APs can adapt to various IoT use cases, such as asset tracking, environmental monitoring, and smart building management.

Huawei's Expertise in Datacom Technologies:

Huawei has been a leader in data communication technologies for over two decades, investing heavily in research and development.

Research Centers Worldwide:

As of the latest documentation, Huawei operates 14 research centers globally. These centers focus on innovation in areas such as 5G, AI, cloud computing, and networking technologies.

Conclusion:The statement is TRUE, as Huawei has indeed established 14 research centers worldwide and has over 26 years of expertise in datacom technologies.

TheAR1000Vis a virtual router designed for deployment in public and private cloud environments. It supports integration with major cloud platforms, including:

Amazon Web Services (AWS):Fully supported for hybrid cloud and SD-WAN deployments.

Alibaba Cloud:Supported for seamless connectivity in Alibaba's cloud ecosystem.

Tencent Cloud:Supported for enterprise-grade cloud networking.

However,Baidu Cloudis not officially supported by the AR1000V, making it the correct answer. This limitation may be due to compatibility or strategic partnerships with other cloud providers.

Factors Affecting Wireless Rate:

The wireless rate (throughput) of a Wi-Fi AP depends on multiple factors, including hardware capabilities, environmental conditions, and configuration settings.

Explanation of Each Factor:

CPU performance:The AP's CPU processes data packets and performs tasks like encryption/decryption. Higher CPU performance enables better throughput.

SNR (Signal-to-Noise Ratio):A higher SNR indicates a stronger signal relative to noise, resulting in better data rates.

Spatial stream:Wi-Fi 6 supports multiple spatial streams (MIMO), increasing throughput by transmitting multiple data streams simultaneously.

Frequency bandwidth:Wider channels (e.g., 20 MHz, 40 MHz, 80 MHz, or 160 MHz) allow higher data rates but may increase interference in crowded environments.

Conclusion:All four options are factors that affect the wireless rate of a Wi-Fi AP.

Understanding Wi-Fi 6 AP Radios:

Wi-Fi 6 APs typically have two or three radios. Three-radio APs provide additional capacity and performance, making them ideal for high-density environments.

Analysis of Each Model:

AirEngine 5762-12:This model supportstwo radios(2.4 GHz and 5 GHz).

AirEngine 6761-21T:This model supportsthree radios, including an additional IoT radio for Internet of Things (IoT) applications.

AirEngine 5761-21:This model supportstwo radios.

AirEngine 5761-11:This model supportstwo radios.

Conclusion:The correct answer is Option B, as the AirEngine 6761-21T supports three radios.

Comprehensive and Detailed in Depth Explanation:Huawei's wireless backhaul solution for rail transportation is designed to provide high reliability and low latency for mission-critical applications such as train control systems.

Option A: The handover delay in Huawei's solution can indeed be as low as 30 ms. This ensures seamless connectivity during transitions between base stations, which is crucial for real-time applications like train control signaling.

Option B: The solution supports carrying train control signal systems, ensuring safe and efficient operations.

Option C: This statement is incorrect. Huawei's wireless backhaul solution supports high-speed mobility, including trains traveling at speeds up to 160 km/h or higher, without losing connectivity.

Option D: Active-active links are a key feature of the solution, providing redundancy and ensuring high reliability even in challenging environments.

Redundancy Technologies for Leaf Switches:

To enhance redundancy in data center networks, technologies like stacking and M-LAG (Multi-Chassis Link Aggregation Group) are commonly used.

Huawei CloudEngine 6881 Capabilities:

TheCloudEngine 6881series switchesdo support M-LAG, enabling active-active redundancy between two switches. This ensures high availability and load balancing.

Conclusion:The statement is FALSE because the CloudEngine 6881 supports M-LAG.
