Huawei H19-315 HCSA-Presales-Transmission & Access Exam Practice Test

Answer : B

The correct answer isMore complex. Enterprise production networks prioritize simplicity, intelligence, and security in optical transmission, rather than unnecessary complexity.

Here's an analysis of each option:

A . More intelligent:Enterprises increasingly demand intelligent networks that leverage AI and automation for tasks like fault detection, performance optimization, and service provisioning.

B . More complex:Complexity is generally undesirable in enterprise networks, as it increases operational overhead, raises costs, and introduces potential points of failure. Modern solutions aim to simplify network architecture while enhancing functionality.

C . Simpler:Simplicity is a key requirement for enterprise networks, enabling easier deployment, management, and troubleshooting. Solutions like converged platforms (e.g., MS-OTN) and automated tools (e.g., NCE-T) help achieve this goal.

D . More secure:Security is critical for protecting sensitive data and ensuring compliance with regulations. Features like hard pipe isolation, encryption, and access control are essential for enterprise networks.

By focusing on intelligence, simplicity, and security, optical transmission solutions can better meet the evolving needs of enterprise production networks.

Huawei Enterprise Optical Networking White Paper

ITU-T G.709 Standards for OTN

Answer : B

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.

Answer : A, B, C, D, E

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

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.

Answer : A

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.
