Important Huawei H19-315 Exam Questions

Answer: D

Explanation:

Type B Protectionin GPON networks refers to link-layer redundancy, where two independent fiber paths are used to connect an ONU to the OLT. In the event of a fiber failure, the system automatically switches to the backup path.

Theminimum protection switching timefor Type B protection is50 ms, ensuring minimal disruption to services. This rapid switching time is critical for maintaining high availability and reliability in mission-critical applications.

Answer: B, D, E

Explanation:

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).

Answer: A

Explanation:

TheNCE-T (Network Cloud Engine - Transport)follows a licensing model that includes both apermanent licenseand anSNS (Software Support and Services)annual fee. Here's how it works:

Permanent License:Grants access to the core features and functionalities of NCE-T indefinitely. This ensures long-term usability without recurring costs for the base software.

SNS Annual Fee:Covers ongoing support, software updates, bug fixes, and technical assistance. Customers must renew this annually to stay current with the latest enhancements and receive priority support.

This hybrid model is common in enterprise-grade software solutions, balancing upfront investment with ongoing operational costs.

Answer: A, B, C, D, E

Explanation:

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

Answer: A

Explanation:

TheOptiXtrans DC908is specifically designed forData Center Interconnect (DCI)applications. Its key features align perfectly with the requirements of modern DCI scenarios:

High Capacity:Supports up to 800G per wavelength, enabling ultra-high-speed connectivity between data centers.

Compact Design:The 2U form factor makes it ideal for space-constrained environments.

Low Latency:Optimized for minimal delays, critical for applications like cloud computing and disaster recovery.

Simplified Deployment:Plug-and-play functionality reduces operational complexity.

While other Huawei products (e.g., OptiXtrans E9600) are designed for backbone or metro networks, the DC908 is tailored exclusively for DCI.
