Huawei Huawei Certified Pre - sales Associate–Transmission&Access(HCPA-ATR) H19-315 Exam Dumps: Updated Questions & Answers (October 2025)

The statement isFalse. While theOptiXtrans E9600andOSN 1800are part of Huawei’s optical transmission portfolio, the1X908andE5800are not included under the OptiXtrans product line.

Here’s a clarification:

OptiXtrans E9600:A series of optical transmission devices designed for backbone, metro, and access networks.

OSN 1800:A compact optical transport platform for enterprise and carrier-grade applications.

1X908:This is not a recognized product in Huawei’s optical transmission portfolio.

E5800:Refers to a different product line, typically associated with access networks rather than optical transmission.

The confusion may arise from overlapping product names, but the OptiXtrans series specifically focuses on optical transmission solutions.

TheNetwork Doctorfeature is designed to providereal-time network quality monitoring,pre-warning, andoptimization of link deterioration. It uses AI-driven analytics to:

Continuously monitor network performance metrics such as latency, jitter, and packet loss.

Identify potential issues before they impact services, enabling proactive maintenance.

Optimize link performance by recommending adjustments to routing, bandwidth allocation, or other parameters.

Other options like "Service Doctor" focus on service-level diagnostics, while "Optical Doctor" and"Fiber Doctor" are specific to optical and fiber-level monitoring, respectively.

The correct answer isSlot 8. In theHuawei EA5800-X15 OLT, thecontrol boardis designed to be installed inSlot 8. The control board serves as the central processing unit of the OLT, managing system operations, traffic forwarding, and communication with other components.

Here’s why Slot 8 is designated for the control board:

Centralized Location:Slot 8 is strategically positioned to ensure balanced power distribution and efficient heat dissipation, which are critical for maintaining system stability.

Redundancy Support:The EA5800-X15 supports dual control boards for high availability, with the second control board typically installed in Slot 7. This redundancy ensuresuninterrupted operation in case of a failure.

Compatibility:Only specific slots are compatible with control boards due to their unique hardware and connectivity requirements.

Slots 9 and 10 are typically reserved for service boards or uplink modules, while Slot 7 may house a secondary control board.

The correct answer isThe management capacity is less than 1000 equivalent NEs.NCE-FAN Liteis a lightweight version of Huawei's Network Cloud Engine for Fixed Access Networks (NCE-FAN), designed for small to medium-sized deployments.

Key characteristics of NCE-FAN Lite include:

Scalability:Suitable for managing up to1000 equivalent NEs (Network Elements), making it ideal for smaller networks like enterprise campuses or regional ISPs.

Cost Efficiency:Offers a simplified feature set compared to the full NCE-FAN, reducing costs for organizations with limited management needs.

Ease of Deployment:Simplifies network operations with centralized monitoring, configuration, and troubleshooting capabilities.

Options A, C, and D refer to larger-scale deployments that exceed the capacity of NCE-FAN Lite. For such scenarios, the full version of NCE-FAN or other advanced management platforms would be required.

TheOptiXtrans E9600 seriesis a robust optical transport solution that supports a wide range of industries and applications, including:

Grid:Ensures reliable communication for smart grid operations, including power distribution and automation.

Traffic:Provides high-bandwidth connectivity for intelligent transportation systems (ITS) and road monitoring.

ISP:Delivers backbone connectivity for internet service providers and data centers.

Safe City:Supports video surveillance, emergency response, and public safety applications.

The versatility of the OptiXtrans E9600 series makes it suitable for diverse use cases, from critical infrastructure to enterprise networks.

POL (Passive Optical LAN)refers to the application of Passive Optical Network (PON) technology in enterprise campus environments. It is a modern networking solution that replaces traditional copper-based Ethernet networks with fiber optics, offering higher bandwidth, longer reach, and lower maintenance costs. POL is widely used in scenarios such as education, healthcare, hospitality, and smart cities.

The other options—Procurement on Line, Port of Loading, and Point of Load—are unrelated to optical networking and refer to entirely different concepts.

The correct answer isOSN 1800 I. TheOSN 1800 Idoes not supportAC power supply; it is designed to operate exclusively onDC power.

Here’s an overview of the options:

OSN 9800:Supports both AC and DC power supplies, making it suitable for diverse deployment scenarios.

OSN 1800 II:Supports both AC and DC power supplies, providing flexibility for different environments.

OSN 1800 I:Designed for compact, cost-effective deployments, it supports onlyDC power, which may limit its use in certain scenarios.

OSN 1800 V:Supports both AC and DC power supplies, catering to high-capacity metro and access networks.

The lack of AC power support in the OSN 1800 I makes it less versatile compared to other models in the series.

TheNCE-T (Network Cloud Engine - Transport)fully supportsvirtualization deployment. It can be deployed as a virtualized application on cloud platforms, leveraging technologies like VMware, OpenStack, or Kubernetes.

Key benefits of virtualization:

Scalability:Virtualized deployment allows NCE-T to scale dynamically based on network demands.

Flexibility:Enables integration with cloud-native environments and multi-vendor ecosystems.

Cost Efficiency:Reduces hardware dependency by running on shared infrastructure.

The statement that NCE-T does not support virtualization is therefore incorrect.

The statement isTrue. TheOSN 1800series is renowned for being theindustry’s highest-integrated 200G transmission solution, capable of supporting services ranging from64Kbps to 100GE.

Key features of the OSN 1800 include:

High Integration:The OSN 1800 combines multiple technologies (e.g., OTN, SDH, Ethernet) into a compact form factor, maximizing space efficiency.

Scalable Capacity:Supports up to200G per wavelength, enabling high-capacity transport for metro and access networks.

Service Flexibility:Can handle a wide range of services, from low-speed TDM (Time Division Multiplexing) circuits (e.g., 64Kbps) to high-speed Ethernet (e.g., 100GE).

Converged Architecture:Integrates OTN, SDH, and packet switching into a single platform, simplifying network operations and reducing costs.

These capabilities make the OSN 1800 ideal for applications like enterprise connectivity, mobile backhaul, and data center interconnects.

TheOSN 9800series is a high-end optical transport platform designed for core and metro-core networks. While it supportsDC power supply, itdoes not natively support AC power supplydue to its high power requirements and deployment in data centers or telecom rooms with dedicated DC infrastructure.

Here’s an analysis of the other options:

OSN 1800 II:Supports both AC and DC power supplies, making it versatile for various deployment scenarios.

OSN 1800 I:Also supports AC power supply, suitable for small-scale and edge deployments.

OSN 1800 V:Designed for outdoor use, it supports AC power with 1+1 redundancy for reliability.

Thus, theOSN 9800is the correct answer.
