Huawei H19-315 Exam Questions

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.

The correct answer isThe management capacity is less than 1000 equivalent NEs. TheNCE-T Liteis a lightweight version of Huawei'sNCE-Tplatform, designed for small to medium-sized optical transport networks with limited management needs.

Key characteristics of NCE-T Lite include:

Scalability:Supports up to1000 equivalent NEs (Network Elements), making it suitable for smaller networks like enterprise campuses, regional ISPs, or edge locations.

Cost Efficiency:Offers a simplified feature set compared to the full NCE-T, reducing costs for organizations with limited budgets.

Ease of Deployment:Simplifies network operations with centralized monitoring, configuration, and troubleshooting capabilities.

Use Cases:Ideal for scenarios where high-end features like advanced analytics or large-scale orchestration are not required.

Other options:

More than 5000, 4000, or 3000 NEs:These refer to larger-scale deployments that exceed the capacity of NCE-T Lite. For such scenarios, the full version of NCE-T or other advanced management platforms would be required.

NCE-T Lite strikes a balance between functionality and affordability, making it accessible for organizations with modest network requirements.

The statement isTrue. TheNCE-T Litedoesnot support virtualization deployment. Instead, it is designed as aphysical applianceorstandalone softwarefor small to medium-sized optical transport networks.

Here's why NCE-T Lite lacks virtualization support:

Target Audience:NCE-T Lite is aimed at organizations with limited network management needs, such as small enterprises or regional ISPs. These users typically do not require the complexity of virtualized environments.

Simplified Architecture:By avoiding virtualization, NCE-T Lite reduces deployment complexity and hardware requirements, making it easier to set up and maintain.

Cost Efficiency:Virtualization often requires additional infrastructure (e.g., hypervisors, servers), which can increase costs. NCE-T Lite avoids these expenses by focusing on a lightweight, non-virtualized design.

In contrast, the full version ofNCE-Tsupports virtualization, enabling it to run on cloud platformsor virtualized environments for large-scale deployments.
