Huawei H19-315 Exam Questions

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.

All the options are correct. TheNCE-T (Network Cloud Engine for Transport)offers a comprehensive suite of features to enhance optical transport network management and service delivery. Here's a breakdown of each highlight:

Visualized Bandwidth Resources:

Provides a graphical representation of bandwidth utilization across the network.

Enables operators to identify bottlenecks, optimize resource allocation, and plan capacity upgrades.

Optical VPN (OVPN):

Creates dedicated virtual paths (hard pipes) for specific services or customers, ensuring isolation and security.

Ideal for applications like financial trading, government communications, and enterprise connectivity.

Optical Service Provisioning:

Automates the provisioning of optical services, reducing manual intervention and speeding up service delivery.

Supports diverse services like OTN, Ethernet, and SDH.

CPE Plug and Play:

Simplifies the deployment of customer premises equipment (CPE) by automating configuration and activation.

Reduces installation time and operational costs, especially for large-scale rollouts.

Optical Latency Map:

Provides real-time visualization of latency across the network.

Helps operators optimize routing for low-latency applications like cloud computing, AI, and 5G backhaul.

These features collectively enhance the efficiency, reliability, and profitability of optical transport networks.

ITU-T G.709 Standards for OTN

The statement isFalse. TheNCE-T (Network Cloud Engine for Transport) does support virtualization deployment, making it highly flexible and scalable for modern optical transportnetworks.

Key aspects of NCE-T's virtualization support include:

Cloud-Native Design:NCE-T can be deployed on cloud platforms, leveraging virtual machines (VMs) or containers for scalability and resource optimization.

Multi-Tenancy:Supports multiple tenants within a single instance, enabling service providers to offer customized solutions to different customers.

Dynamic Scaling:Automatically adjusts resource allocation based on network demand, ensuring optimal performance during peak loads.

Integration with NFV:Works seamlessly with Network Function Virtualization (NFV) frameworks, enabling convergence with other virtualized network functions.

Virtualization enhances NCE-T's capabilities, making it suitable for large-scale, carrier-grade deployments where flexibility and scalability are critical.
