Huawei H19-315 Exam Questions

A Passive Optical Network (PON) system consists of three primary components:

OLT (Optical Line Terminal):The central device located at the service provider's premises. It connects to the core network and manages communication with multiple ONUs.

ONU (Optical Network Unit):The customer-side device located at the user's premises. It converts optical signals into electrical signals for end-user devices.

ODN (Optical Distribution Network):The passive infrastructure that includes optical fibers, splitters, and connectors to distribute signals between the OLT and ONUs.

WDM (Wavelength Division Multiplexing) is a technology used in optical networks but is not a basic component of a PON system. It is often used in advanced PON systems like XG-PON or NG-PON2 to separate upstream and downstream wavelengths.

TheOptiXtrans DC908supports multiple management systems to ensure efficient operation and monitoring. Here's an analysis of each option:

NCE-T Lite:The DC908 does not supportNCE-T Lite, as this is a simplified version of the Network Cloud Engine (NCE) designed for smaller-scale deployments.

CLI (Command-Line Interface):The DC908 supports CLI for advanced configuration and troubleshooting tasks.

eSight:While eSight is a powerful network management system, it is not typically used for managing the DC908. Instead, the DC908 relies on NCE or WebGUI.

WebGUI:The DC908 provides aWeb-based Graphical User Interface (WebGUI)for intuitive and user-friendly management.

NCE (Network Cloud Engine):The DC908 integrates withNCEfor centralized control, automation, and intelligent O&M capabilities.

Thus, the correct answers areB (CLI), D (WebGUI), and E (NCE).

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.

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.

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.
