H19-102_V2.0 Exam Dumps and Practice Questions

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.

HCSA-Sales-Transmission & Access Official Documentation -- PON Architecture

ITU-T G.984 Standard for GPON

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.

In education (e.g., universities), Campus OptiX advantages, per HCSA-Sales-Transmission & Access, include:

1 Day Service Ready (A): Rapid deployment via POL.

100Mbps @ Everywhere (C): High bandwidth across campus.

1 Terminal @ 1 Room (B): More hotel-specific; education focuses on coverage.

Thus, A and C are correct.

The Huawei OptiXtrans DC908 is a Data Center Interconnect (DCI) solution tailored for high-performance, low-latency, and simplified deployment in data center scenarios. While Huawei's optical solutions, including the DC908, are widely deployed globally, the specific claim of '620,000+ optical devices commercially used worldwide' is not explicitly documented as a key feature of the DC908 in official HCSA-Sales-Transmission & Access materials. The DC908's key features focus on aspects like high capacity (e.g., 88T per fiber), low power consumption (35% lower than the industry average), rapid commissioning (within 8 minutes), and cost-effective payback (within 1 year for self-built networks). The figure of 620,000+ devices might pertain to Huawei's broader optical portfolio, but it is not a verified key feature specific to the DC908. Thus, the statement is FALSE in this context.

Huawei's OLT family (SmartAX series) includes models like EA5800-X17, X7, X2, and others, totaling at least 4 variants, per HCSA-Sales-Transmission & Access, making A correct.
