H19-102_V2.0 Exam Questions & Answers

DCI stands for Data Center Interconnect, a term widely used in the industry and explicitly defined in HCSA-Sales-Transmission & Access materials. It refers to technologies (e.g., Huawei OptiXtrans DC908) that link multiple data centers for high-speed, low-latency data transfer. The statement is accurate, making it TRUE.

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 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.

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.

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.
