Huawei H19-315 Exam Questions

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.

POL Deployment Scenarios

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.

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.

All the options are correct. TheHuawei OSN 1800offers several advantages when used in theGrid industry, making it an ideal solution for smart grid communications.

Here's how each advantage applies:

High Secure Hard Pipe:Provides dedicated bandwidth for mission-critical applications like SCADA (Supervisory Control and Data Acquisition), ensuring secure and reliable communication.

Isolation Hard Pipe:Ensures complete isolation between different services, preventing interference and enhancing security.

Built-in PCM:Supports legacy analog and digital services, enabling seamless integration with existing grid infrastructure.

MS-OTN (Multi-Service Optical Transport Network):Combines OTN, SDH, and Ethernet capabilities, offering a converged platform for diverse grid applications.

The OSN 1800's flexibility, security, and support for multiple technologies make it well-suited for the demanding requirements of the Grid industry.

The correct definition ofPOL (Passive Optical LAN)is that it is the application of PON (Passive Optical Network) technology in the enterprise campus environment. POL leverages the advantages of fiber optics, such as high bandwidth, long transmission distances, and low maintenance costs, to provide a converged network solution for enterprises. It replaces traditional copper-based LANinfrastructure with an all-optical network, supporting services like data, voice, and video over a single fiber.

Procurement on Line, Purchasing Online System:This is unrelated to POL and refers to online procurement systems.

Point of Load:Refers to power electronics and is unrelated to optical networks.

Port of Loading:A logistics term referring to the location where goods are loaded onto a carrier, unrelated to POL.
