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

Answer : C

TheeSightoffering includes both the software and hardware components required for network management. Specifically, when quoting eSight, the package typically includes:

TheeSight software, which provides comprehensive network management capabilities.

Thehardware server(e.g., Huawei FusionServer or TaiShan Server) on which the software is deployed.

Options like 'Network Cloud Engine-FAN' and 'NCE_FusionCompute' are unrelated to eSight, while 'eSight Outsourcing' refers to managed services rather than a hardware-inclusive package.

TheOptiXtrans E9624is a high-end optical transport platform designed for core networks. Itsmaximum cross-connect capacity is 24 Tbps per subrack, not 2.4 Tbps as stated in the question. This makes it one of the most powerful systems in Huawei's optical transport portfolio, capable of handling massive traffic volumes in backbone and metro-core networks.

The confusion may arise from other models in the series, such as the OptiXtrans E9605, which has a lower capacity. However, the E9624 is specifically engineered for ultra-high-capacity scenarios.

TheOSN 1800 Vis a compact device designed for outdoor and edge deployments. Unlike other models in the OSN 1800 series, itcannot be mounted in a standard 19-inch cabinetdue to its unique form factor and intended use case.

Here's an analysis of the other options:

OSN 1800 I:Can be mounted in a 19-inch cabinet and is commonly used in small-scale deployments.

OSN 9800 U32:A high-end platform designed for core networks, typically deployed in data centers or telecom rooms with 19-inch racks.

OSN 1800 II:Supports 19-inch cabinet mounting and is used in metro and regional networks.

Thus, theOSN 1800 Vis the correct answer.

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.

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.

TheNCE-T (Network Cloud Engine - Transport)is a comprehensive platform for managing optical transport networks. Its key highlights include:

Visualized Bandwidth Resources:Provides real-time visibility into network bandwidth usage, enabling efficient resource allocation.

Optical VPN (OVPN):Supports virtual private networks over optical transport networks, ensuring secure and isolated connectivity for different tenants.

Optical Latency Map:Displays end-to-end latency across the network, helping optimize performance for latency-sensitive applications.

Optical Service Provisioning:Automates the provisioning of optical services, reducing manual intervention and speeding up deployment.

CPE Plug and Play:Simplifies the deployment of customer premises equipment (CPE) by enabling zero-touch provisioning.

These features make the NCE-T a powerful tool for managing modern optical networks.
