Free Huawei H19-102_V2.0 Practice Exam with Questions & Answers | Set: 2

Passive Optical LAN (POL) is Huawei’s all-optical solution for enterprise networks, replacing traditional copper-based LANs with fiber optics. HCSA-Sales-Transmission & Access materials confirm that POL, part of the Campus OptiX portfolio, is designed for enterprise environments and is widely applicable in scenarios such as:

Education (e.g., universities),

Healthcare (e.g., hospitals),

Airports,

Electric power, and

Smart cities.

Its benefits include simplified architecture, high bandwidth, and long-distance coverage (up to 40km), making the statement TRUE.

Customer pain points in transmission and access contexts (e.g., DCI, POL) are well-documented in HCSA-Sales-Transmission & Access:

High cost (B): Rising bandwidth and leased line costs are a universal concern across industries.

Difficult O&M (D): Complex operations and maintenance challenge customers, especially in DCI or legacy LANs.

High Availability (A): This is a requirement, not a pain point; customers seek it rather than suffer from it.

Frequent stock transactions (C): A financial sector need, not a general pain point in transmission/access.

Thus, B and D are the verified pain points.

Huawei’s Campus OptiX (IP+POL) solution integrates IP and Passive Optical LAN technologies to deliver value to enterprise customers. Per HCSA-Sales-Transmission & Access documentation:

Converged O&M (A): The solution uses eSight NMS to manage both IP and POL equipment, providing unified operations and maintenance, reducing complexity.

Green and Efficient Engineering (B): POL’s passive nature saves power, cabling, and space, while simplified deployment (e.g., fewer layers) enhances engineering efficiency.

Ultra-Broadband (C): While Campus OptiX supports high bandwidth (e.g., GPON to 10GPON evolution), this is a technical capability rather than a distinct "value" highlighted in sales materials, which focus more on O&M and engineering benefits.

Thus, A and B are the verified values.

DC908 simplifies DCI deployment with WebGUI and rapid commissioning, but it doesn’t shift from mainframes to blade servers (an IT architecture change), per HCSA-Sales-Transmission & Access. It’s designed for optical interconnect, making the statement FALSE.

A self-built Data Center Interconnect (DCI) provides several advantages:

✅High Efficient O&M – With self-built DCI, enterprises have full control over network monitoring, fault management, and performance optimization, reducing dependency on external providers.

✅Service Rollout on Time – Unlike leased lines, a self-built DCI network allows rapid service deployment without waiting for telecom operators, improving efficiency.

❌Guaranteed Quality – While a self-built network offers more control, it does not always guarantee quality compared to carrier-grade leased lines with SLAs (Service Level Agreements).

Thus, the correct answer is A and C.

POL’s passive optical design (e.g., ODN with splitters) eliminates active equipment, reducing power consumption by up to 50% vs. active Ethernet, per HCSA-Sales-Transmission & Access,making the statement TRUE.

The finance industry heavily relies on DCI solutions for data replication, high availability, and disaster recovery. Key pain points include:

✅Increased leased line prices – Financial institutions require dedicated high-bandwidth connections, and leased line costs continue to rise.

✅Financial disaster recovery – To meet compliance regulations and business continuity requirements, banks and financial firms must deploy redundant DCI networks for real-time data backup and disaster recovery.

Thus, the correct answer is TRUE.

The Huawei OptiXtrans DC908 is designed for flexible deployment and can be co-deployed with IT devices in the same rack.

✅Compact Design – Supports 2U/5U chassis, allowing easy integration with IT servers and storage devices in standard 19-inch racks.

✅Reduced Space & Power Consumption – Eliminates the need for separate optical networking racks, saving data center space and power costs.

Thus, the correct answer is TRUE.

Huawei’s Campus OptiX, based on POL technology, is tailored for various scenarios, including airports. According to HCSA-Sales-Transmission & Access documents, the key advantages in the airport scenario include:

Smart O&M (A): Campus OptiX leverages eSight NMS for intelligent operations and maintenance, simplifying network management in large-scale environments like airports.

Up to 40km Coverage (C): POL’s passive optical architecture supports long-distance coverage (up to 40km), ideal for expansive airport campuses.

Ultimate Wi-Fi Experience (B): While Campus OptiX supports high-speed connectivity, this advantage is more emphasized in scenarios like hotels or offices with Wi-Fi roaming features, not specifically highlighted for airports.

Thus, A and C are the verified advantages.

In a Passive Optical LAN (POL), the Optical Distribution Network (ODN) consists entirely of passive optical components such as splitters, connectors, and fibers. These components do not require external power, making them fully passive.

The ODN in POL follows Point-to-Multipoint (P2MP) architecture using passive splitters, ensuringsignal distribution without electrical conversion. Since no active components are present in the ODN, it remains maintenance-free and energy-efficient.
