H19-102_V2.0 HCSA-Sales-Transmission & Access V2.0 Questions and Answers

PON is Passive Optical Network, but it uses a point-to-multipoint (P2MP) topology, not P2P, per HCSA-Sales-Transmission & Access. P2P dedicates a fiber per user, while PON shares via splitters, making the statement FALSE.

DCI is Data Center Interconnect, per HCSA-Sales-Transmission & Access. The negation is incorrect, making it FALSE.

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.

DC908 features front air inlet and rear air outlet, per HCSA-Sales-Transmission & Access, for data center compatibility. The negation is incorrect, making it FALSE.

POL’s scenarios, per HCSA-Sales-Transmission & Access, include:

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.

Thus, A, C, and D are correct.

eSight NMS, used in Campus OptiX, has features per HCSA-Sales-Transmission & Access:

Installation easy (B): Quick setup for unified management.

Simple detection (C): Efficient fault identification.

Clear visualization (D): Intuitive network monitoring.

Free upgrade (A): Not a standard feature; upgrades may involve licensing.

Thus, B, C, and D are correct.

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.

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.

Fiber optic cables in POL and DCI solutions have a lifecycle of 30 years, per HCSA-Sales-Transmission & Access, due to their durability and passive nature, making B correct.

Huawei's Campus OptiX (POL) solution uses a single optical fiber to carry multiple services simultaneously, including:

✅Wi-Fi – Fiber backhaul for wireless access points.✅Internet – High-speed broadband access.✅Telephone (VoIP/POTS) – Voice services over optical fiber.✅TV (IPTV, CATV) – Video transmission over the same infrastructure.

Since optical fiber has high bandwidth and low latency, it can efficiently transmit all these services using different wavelengths or logical VLANs.

Thus, the correct answer is TRUE.

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.

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.

POL simplifies traditional multi-layer LANs (e.g., core, aggregation, access) into a 2-layer architecture (OLT to ONU via ODN), per HCSA-Sales-Transmission & Access. This reduces complexity and equipment, making the statement TRUE.

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.

High-level customers in DCI scenarios (e.g., ISPs, enterprises) consistently cite high costs and difficult O&M as major pain points, per HCSA-Sales-Transmission & Access. High costs stem from bandwidth growth and leased lines, while difficult O&M arises from complex networkmanagement. The statement negates these documented issues, making it FALSE. (Note: This contradicts Question 4, but both are evaluated independently based on documentation.)

The Huawei OptiXtrans DC908 is designed for flexible deployment in different data center environments. It supports:

✅197 ETSI rack compatibility – Ensuring industry-standard installation options.✅600mm, 800mm, 1000mm, and 1200mm depth installation – Making it adaptable to different rack sizes for seamless integration into various data centers.

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.

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.

The OptiXtrans DC908 supports WebGUI-based network management. Huawei provides an intuitive Graphical User Interface (GUI) that allows users to configure, monitor, and manage DCI networks without requiring a CLI (Command Line Interface).

Key Features of DC908 WebGUI:✅Real-time monitoring of optical links and alarms✅Plug-and-play setup without complex configurations✅Intelligent network diagnosis for fault detection

Thus, the statement is FALSE because WebGUI is supported for managing OptiXtrans DC908.
