H19-102_V2.0 Sample Questions Answers

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.

This statement directly reflects a well-documented pain point in DCI scenarios as per HCSA-Sales-Transmission & Access materials. The rapid growth of DCI traffic (over 50% annually) is driven by increasing data demands from cloud services, video streaming, and enterprise applications. Meanwhile, bandwidth costs doubling every two years exacerbate the financial burden on customers, pushing them toward cost-efficient solutions like Huawei’s DC908, which offers a payback period within 1 year for self-built networks. The statement accurately captures this dynamic, making it TRUE.

Campus OptiX (IP+POL) saves investment, per HCSA-Sales-Transmission & Access:

Capex: Reduces costs for active equipment (fewer switches), cabling (fiber vs. copper), and construction (simplified architecture).

Opex: Lowers power, maintenance, and operational costs due to passive design.

Option C fully captures these savings, making it correct.

eSight is Huawei’s Network Management System (NMS) for Campus OptiX, managing IP and POL equipment, per HCSA-Sales-Transmission & Access. It provides converged O&M, making the statement TRUE (YES).

The All-Optical PON Architecture, as part of Huawei’s POL and Campus OptiX solutions, replaces traditional active Ethernet LANs with passive optical components, yielding significant engineering savings. According to HCSA-Sales-Transmission & Access documentation:

Cabling Space (A): Fiber optic cables are thinner and lighter than copper, reducing cabling space requirements.

IT Room Space (B): Passive architecture eliminates the need for intermediate active equipment (e.g., switches), freeing up IT room space.

Power Consumption (C): Passive components (e.g., splitters) require no power, significantly lowering energy use compared to active Ethernet setups.

Since all these aspects (A, B, C) are documented benefits, "All above" (D) is the correct answer.

POL in Campus OptiX supports Wi-Fi roaming, Network Access Control (NAC), free mobility, and Software-Defined Networking (SDN) via ONUs with Wi-Fi 6 and eSight management, per HCSA-Sales-Transmission & Access. This versatility suits various office scenarios, making the statement TRUE.

Campus networks today face several key challenges:

✅Hard to expand/upgrade cabling system – Traditional Ethernet-based campus networks require extensive copper cabling, which is difficult to expand and upgrade, leading to higher costs and complexity.

✅Chimney networks hard to maintain – Many legacy campus networks operate in a chimney-style architecture (vertical silos of network systems), making it difficult to manage and integrate different services.

❌Restriction of 100m makes network complex – While Ethernet has a 100m distance limit, modern fiber-based Passive Optical LAN (POL) solutions overcome this restriction, making this less of a challenge today.

❌Devices are too large – Modern networking equipment is compact and modular, making device size less of a concern in today’s campus networks.

Thus, the correct answers are A and D.

Huawei’s strengths in the transmission and access domain are well-documented in HCSA-Sales-Transmission & Access materials:

Leadership in the industry (A): GlobalData’s analysis positions Huawei as a DCI leader, reflecting its market dominance and innovation, a key strength highlighted in sales training.

R&D investment (B): Huawei’s extensive R&D infrastructure, with over 7,000 employees, 17 R&D centers, and global support networks, drives its technological edge, as per official figures.

Standards and patents (C): Huawei’s significant contributions to optical standards (60%) and patents (42%) underscore its technical leadership, though exact percentages may vary slightly in documentation.

All options (A, B, C) are verified strengths.

Huawei’s Campus OptiX, based on POL, is versatile for enterprise scenarios. HCSA-Sales-Transmission & Access documents confirm its deployment in:

Education (University): Supports high-bandwidth, long-distance (40km) campus networks.

Hotel: Offers fiber-to-room and cost-efficient solutions.

The statement is accurate, making it TRUE.

Campus OptiX supports GPON (2.5Gbps) and evolves to 10GPON (10Gbps) using the same OLT and ODN, per HCSA-Sales-Transmission & Access, ensuring future-proofing, making the statement 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.

Technical-level customers (e.g., engineers) in DCI scenarios face high costs (bandwidth, equipment) and difficult O&M (complex planning, maintenance), as per HCSA-Sales-Transmission& Access. DC908 addresses these with low per-bit costs and simplified deployment, making the statement TRUE.

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.

Huawei’s Campus OptiX solution is a multi-service network capable of delivering all major digital services over a single optical fiber infrastructure:

✅Internet – High-speed broadband access via fiber.✅Telephone – Supports traditional POTS and VoIP services.✅Wi-Fi – Provides fiber backhaul for wireless access points (APs).✅TV (IPTV & CATV) – Distributes video services efficiently over the same network.

Since Campus OptiX can handle all these services, the correct answer is E (All of the above).

The Huawei OptiXtrans DC908 is a high-performance Data Center Interconnect (DCI) solution designed specifically for DCI applications.

✅High-capacity transmission – Supports 800G per wavelength to handle large-scale data centertraffic.✅Simplified deployment – Uses intelligent management tools for plug-and-play operations.✅High reliability – Supports multi-layer protection and low latency for critical data center connectivity.

Dormitory in University (A): High-bandwidth campus needs.

Guest room in Hotel (C): Fiber-to-room deployments.

Wards in hospital (D): Reliable, scalable connectivity.

Apartment (B): More residential FTTH, less POL-focused.

eSight is Huawei’s network management system (NMS) designed to provide centralized management for various network elements. In the context of the Campus OptiX solution, HCSA-Sales-Transmission & Access documents confirm that eSight supports converged management of both IP-based equipment (e.g., switches, routers) and POL components (e.g., OLTs, ONUs). This capability enables unified monitoring, configuration, and fault detection across the hybrid IP+POL architecture, enhancing operational efficiency. The statement is consistent with eSight’s documented functionality, making it TRUE.

Passive Optical Networks (PON) use a Point-to-Multipoint (P2MP) topology where a single Optical Line Terminal (OLT) connects to multiple Optical Network Units (ONUs) or Optical Network Terminals (ONTs) using passive splitters.

✅Efficient Bandwidth Sharing – A single fiber from the OLT is split among multiple users, reducing fiber deployment costs.

✅Scalable and Cost-Effective – Supports higher user density with minimal fiber usage.

Since PON does not follow a Point-to-Point (P2P) model, the correct answer is P2MP.
