Understanding Overlay Topologies in SD-WAN:

In Huawei's SD-WAN solution, overlay networks are created on top of the physical underlay network. These overlays can be customized based on specific services or applications.

Service Independence:

Different service topologies (e.g., voice, video, data) areindependent of each other, allowing granular control over traffic paths, QoS policies, and security settings.

Conclusion:The statement is TRUE because overlay topologies in Huawei's SD-WAN solution are service-specific and operate independently.

Overview of S5731-L Remote Units (RUs):

The S5731-L series includes remote units (RUs) designed for distributed campus networks. These RUs connect to a central switch via uplink ports.

Uplink Port Flexibility:

The RUs supportoptical, electrical, and hybrid optical-electrical ports, allowing flexible selection based on the distance between the RU and the central switch.

Optical ports are used for long-distance connections, while electrical ports are suitable for shorter distances. Hybrid ports combine both options for maximum versatility.

Conclusion:The statement is TRUE because the S5731-L RUs support multiple uplink port types for flexible deployment.

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.

Hyper-converged data center network solutions emphasize automation across the entire lifecycle, from deployment to operations. Below is an analysis of each option:

100% unleashing of computing power : While automation can optimize resource allocation, achieving 100% utilization of computing power is not directly tied to full-lifecycle automation.

TTM reduced by 90% : Full-lifecycle automation streamlines processes such as provisioning, configuration, and scaling, significantly reducing Time-to-Market (TTM). This is a direct benefit of automation.

Proactive prediction of 90% of faults : Proactive fault prediction is typically achieved through AI-driven analytics, not solely through automation.

Storage performance improved by 90% : Improvements in storage performance are more closely related to advancements in hardware (e.g., NVMe over Fabrics) and software optimizations, rather than automation.

Thus, the correct answer is B , as full-lifecycle automation primarily reduces TTM.

Overview of Huawei CloudCampus 3.0:

Huawei CloudCampus 3.0 is designed to provide a fully-wireless, intelligent, and cloud-based campus network solution. It focuses on improving efficiency, reducing costs, and enabling digital transformation.

Analyzing Each Option:

Option A:"One global network: 40% lower private line costs" is correct. Huawei CloudCampus 3.0 reduces private line costs by leveraging cloud-based technologies and SD-WAN solutions.

Option B:"L3 autonomous driving: 90% fewer complaints" is correct. The solution uses AI-driven automation to minimize network issues and improve user satisfaction.

Option C:"Low-carbon intelligence: 60% smaller energy consumption of the entire network" isnot correct. While Huawei emphasizes energy efficiency, the claim of a 60% reduction in energy consumption is exaggerated and not supported by official documentation.

Option D:"Fully-wireless experience: 40% higher productivity" is correct. The fully-wireless architecture enhances user experience and productivity.

Conclusion:The incorrect benefit description is Option C.

HuaweiiMaster NCE(Network Cloud Engine) is an intelligent network automation platform that integratesmanagement, analysis, and controlcapabilities, but it doesnot handle routing functions directly.

(A) Management – True: iMaster NCE provides centralizednetwork lifecycle management, including configuration, monitoring, and automation.

(B) Routing – False: Routing is handled by network devices like routers and switches, not by iMaster NCE itself.

(C) Analysis – True: The platform incorporatesbig data analyticsto provide network insights, fault prediction, and performance optimization.

(D) Control – True: iMaster NCE serves as anSDN controller, managing network policies, path selection, and automation.

Huawei Datacom Product Line Overview:

Huawei's datacom product line provides comprehensive solutions across multiple domains to meet diverse customer needs.

Domains Covered by Huawei Datacom:

Cyber Security:Products and solutions for network security, including firewalls and intrusion detection systems.

Network Management:Tools for managing and monitoring networks, such as iMaster NCE.

Backbone Router:High-capacity routers for core and backbone networks.

Conclusion:The statement is TRUE, as Huawei's datacom product line indeed covers these six domains.

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.

Understanding Telnet:Telnet is a protocol used for remote management of networkdevices. Unlike console port management, which requires a physical connection, Telnet operates over the network.

Address Requirement:For Telnet communication to occur, the client must have an IP address. This is because Telnet relies on the TCP/IP protocol suite, and communication is established using IP addresses.

Why Not Other Options?

VLAN:A VLAN (Virtual Local Area Network) is a logical segmentation of a network but does not directly represent an address for communication.

AS:An Autonomous System (AS) is a collection of IP networks under a single administrative domain, not an address type.

MAC:A MAC address is a hardware identifier used at Layer 2 of the OSI model. While important for local network communication, it is not sufficient for Telnet, which operates at Layer 3.

Conclusion:The correct answer is IP, as it is the fundamental addressing scheme required for Telnet communication.

The Huawei AC6805 is a high-performance wireless access controller designed for large-scale enterprise networks. It supports up to 120 Gbps of forwarding capacity, enabling it to handle high-density Wi-Fi deployments and demanding applications like video streaming and IoT.

The other options (60 Gbps, 40 Gbps, and 100 Gbps) do not match the specifications of the AC6805. While lower-end models in the AC series may have reduced forwarding rates, the AC6805 is specifically designed to deliver exceptional performance for large-scale networks.

Thus, the correct answer is A .
