Answer : A, B, C, D

TheFTTx (Fiber-to-the-x)solution is a versatile technology that enables the delivery of multiple services over a single fiber-optic infrastructure. The key services provided by FTTx include:

High-Speed Internet:Delivers broadband connectivity to homes, businesses, and institutions.

Home-WiFi:Supports wireless networking within premises using Wi-Fi-enabled ONTs or routers.

Telephone:Provides Voice over IP (VoIP) services for telephony applications.

IPTV:Enables high-quality video streaming for entertainment and educational purposes.

FTTx solutions are widely used in Fiber-to-the-Home (FTTH), Fiber-to-the-Building (FTTB), and Fiber-to-the-Curb (FTTC) deployments, offering converged services to meet diverse customer needs.

When deployingNCE-FAN Liteon aBare Metalinfrastructure, Huawei recommends using theTaiShan Server, which is part of its ARM-based server portfolio. In this scenario, the correct offering to select isNetwork Cloud Engine-FAN Lite HW.

The 'HW' suffix indicates that the solution includes hardware components (e.g., the TaiShan Server) in addition to the software. This is ideal for customers who prefer an integrated hardware and software package rather than deploying the software on their own servers.

Other options like 'Network Cloud Engine-FAN Lite' or 'NCE_FusionCompute' are software-only solutions and do not include the TaiShan Server.

Answer : A

The correct answer isRoom-like scenarios, including education, hotel, medical, apartment. Campus OptiX (POL) is primarily designed for enterprise campus environments where high bandwidth, low latency, and simplified network architecture are required. Common scenarios include:

Education:Connecting classrooms, dormitories, and administrative offices.

Hotels:Providing high-speed internet and IPTV services to guests.

Medical:Supporting hospital networks for patient care, imaging, and telemedicine.

Apartments:Delivering triple-play services (data, voice, video) to residents.

While options like video backhaul and Wi-Fi backhaul are valid use cases for optical networks, they are typically associated with carrier-grade solutions rather than enterprise-focused Campus OptiX deployments.

Answer : C

The correct answer isFiber Doctor. TheFiber Doctorfeature is specifically designed to monitor the status of optical fibers and quickly identify fault points in the network.

Here's how Fiber Doctor works and why it's essential:

Real-Time Monitoring:Continuously monitors fiber health, detecting issues like attenuation, breaks, or degradation.

Fault Localization:Uses advanced algorithms to pinpoint the exact location of faults, reducing the time and effort required for troubleshooting.

Proactive Maintenance:Identifies potential issues before they impact service, enabling preventive maintenance and minimizing downtime.

Visualization:Provides a graphical representation of the fiber network, making it easier for operators to understand and address problems.

Other options:

Optical Doctor:Focuses on optimizing optical signal quality but does not specialize in faultlocalization.

Service Doctor:Monitors service performance (e.g., latency, packet loss) rather than physical fiber status.

Wavelength Doctor:Ensures proper wavelength allocation in WDM systems but does not monitor fiber health.

TheCampus OptiX solutionis a comprehensive offering that integrates multiple components to deliver a complete Passive Optical LAN (POL) solution. The main sale products include:

OLT (Optical Line Terminal):Central device for managing the network.

ODN (Optical Distribution Network):Passive infrastructure for signal distribution.

ONU/ONT (Optical Network Unit/Terminal):Customer-side devices for connecting end-users.

eSight:Huawei's network management system (NMS) for centralized monitoring and management of the entire network.

While options like 'OLT + ODN + ONU' or 'OLT + ONT' represent subsets of the solution, the inclusion ofeSightis critical for effective network management and operation, making option A the most complete and accurate choice.

TheNCE-FAN (Network Cloud Engine - Fiber Access Network)is a comprehensive platform for managing fiber access networks. It consists of three core modules:

Management Module:Handles device configuration, fault monitoring, and performance management.

Control Module:Provides centralized control over network resources, enabling features like automatic service provisioning and policy enforcement.

Analysis Module:Uses AI and big data analytics to provide insights into network performance, user behavior, and potential issues.

These modules work together to deliver intelligent, efficient, and scalable management of fiber access networks.

TheCampus OptiX (POL)solution is primarily deployed in scenarios where fiber-to-the-premises (FTTP) is required for high-speed connectivity. The main sale scenarios include:

Room-like Scenarios:POL is widely used in education (classrooms, dormitories), hotels (guest rooms), hospitals (patient rooms), and apartments, where individual units require dedicated connectivity.

Video Backhaul Scenarios:POL supports video surveillance and backhaul applications in safe city projects, parks, and industrial zones, ensuring reliable and high-quality video transmission.

While POL can technically support office and Wi-Fi backhaul scenarios, these are not its primary focus. Instead, these scenarios are better addressed by other Huawei solutions like Wi-Fi 6 or enterprise switches.
