In Huawei's SD-WAN solution, the Route Reflector (RR) plays a critical role in distributing routing information across the network. However, the RR does not directly participate in service traffic forwarding. Its primary function is to facilitate efficient route exchange between SD-WAN nodes.

If the RR fails, it may temporarily disrupt the distribution of routing updates, but it will not interrupt service traffic on the entire network. Service traffic continues to flow through established paths until the RR is restored or redundancy mechanisms take effect.

To ensure high availability, the RR is often deployed in redundancy mode, but the claim that its failure will interrupt all service traffic is FALSE .

Overview of the S8700 Switch:

The S8700 series is part of Huawei's high-end campus core switches, designed for large-scale enterprise networks. It offers advanced hardware features to meet demanding requirements.

Analysis of Each Option:

Option A:The S8700 supports ultra-high PoE++ output capability, enabling long-distance power delivery for devices such as Wi-Fi access points and IP cameras.

Option B:The main control boards in the S8700 operate in 1:1 backup mode, ensuring seamless failover without packet loss or performance degradation.

Option C:This statement is incorrect. Service subcards arenot integratedon the main control board panel; they are separate components that enhance flexibility.

Option D:The S8700 supports ultra-high-density cards with GE optical, GE electrical, and 10GE optical ports, providing versatile connectivity options.

Conclusion:The correct hardware characteristics are Options A, B, and D.

SecoManager supports multiple deployment modes to meet the needs of different security scenarios. Below is an analysis of each option:

Independent deployment : SecoManager can be deployed as a standalone solution for managing security devices across the network.

Integrated deployment with iMaster NCE-IP : SecoManager can integrate with iMaster NCE-IP to provide unified management of IP/MPLS networks and security policies.

Integrated deployment with iMaster NCE-Campus : This is not a supported deployment mode for SecoManager. SecoManager focuses on security management, while iMaster NCE-Campus is tailored for campus network management.

Integrated deployment with iMaster NCE-Fabric : SecoManager can integrate with iMaster NCE-Fabric to manage security policies in cloud data centers and intent-driven networks.

Thus, the correct answer is C , as SecoManager does not support integration with iMaster NCE-Campus.

Comparison of Uplink Ports and Reliability:

Non-Huawei switches often rely on subcards to expand uplink ports, which can introduce complexity and potential points of failure.

Huawei S6730-H24X6CI and S6730-H48X6C switches come withbuilt-in six 100GE uplink ports, eliminating the need for additional subcards. This design simplifies deployment and enhances reliability.

Advantages in Project Response:

Built-in uplink ports reduce configuration time and improve operational efficiency.

Higher reliability ensures consistent performance, which is crucial for mission-critical applications.

Conclusion:The statement is TRUE because the S6730-H series switches offer built-in 100GE uplink ports and superior reliability compared to non-Huawei switches.

Huawei'sAI roaming technologyenhances wireless network performance by optimizing roamingbehavior for client devices (STAs). Key features include:

Optimal roaming experience:Ensures seamless roaming for different types of STAs, improving wireless speeds by up to30%.

Flexible steering policies:Supports dynamic and differentiated steering based on STA profiles, making option BFALSE.

802.11V support:Requires STAs to support the 802.11V standard for efficient roaming.

The claim that roaming steering policies are inflexible is incorrect, as AI roaming leverages intelligent algorithms to adapt policies dynamically based on network conditions and device characteristics.

iStack (Intelligent Stacking)andCSS (Cluster Switching System)are twohigh-availability networking technologiesused to logically combine multiple switches for better redundancy and scalability.

(A) True – CSS (Cluster Switching System)allowstwo or more modular switchesto function as one logical switch. CSS-capable switches connect usingCSS cables.

(B) True – iStackallows multiplefixed switchesto be stacked together into a single logical unit usingiStack cables.

(C) True – CSS is supported by modular switches, whileiStack is supported by fixed switches. Onlytwoswitches can form a CSS cluster.

(D) False – iStack supports more than two switches, making this statement incorrect.

SD-WAN (Software-Defined Wide Area Network)is a transformative technology that enhances traditional WAN architectures. Its key characteristics include:

Automatic and intelligent O&M:Centralized management and real-time visibility simplify operations and improve troubleshooting.

Zero Touch Provisioning (ZTP):Enables rapid deployment of branch offices without manual configuration, reducing time and effort.

Dynamic traffic steering:Adjusts traffic paths based on application priorities, ensuring optimal performance for critical applications.

Value-added services:Integrates WAN optimization, security, and other services to enhance network capabilities and streamline service delivery.

These features make SD-WAN a preferred solution for modern enterprises seeking agility, scalability, and cost efficiency.

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.

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.
