Huawei H20-923_V1.0-ENU 問題集 練習問題・模擬試験｜日本語版＆英語版対応

Explanation: Huawei’s scenario-based data center facility portfolio is organized around clearly defined solution families that map to typical deployment scenarios and site sizes. FusionModule500 and FusionModule2000 are smart modular data center solutions designed for standardized, fast deployment in equipment rooms and enterprise edge/branch scenarios. They integrate key subsystems such as power supply and distribution, cooling, monitoring, and optional fire protection into a modular architecture that reduces footprint and accelerates on-site delivery. Likewise, FusionDC1000 is Huawei’s prefabricated modular data center series, delivered as complete, factory-integrated modules that combine civil engineering elements with electromechanical infrastructure for rapid construction, predictable quality, and scalable expansion across different capacity tiers. In contrast, FusionDC800 is not used as a defined scenario-based solution name within Huawei’s mainstream data center facility solution lineup (where “FusionDC” offerings are represented by the FusionDC1000 series and “FusionModule” offerings by numbered FusionModule solutions). Therefore, FusionDC800 is the option that does not match Huawei’s scenario-based solution naming

Explanation: In the FusionDC1000A IT scenario, the external input power cables are designed to enter the power distribution system through dedicated cable inlets at the bottom of the Power PDB. During installation, the procedure requires opening the Power PDB, removing the plugs from the bottom cable holes, and routing the external input power cables into the cabinet through these bottom entries before arranging them along the nearby cable support/bridge inside the Power PDB area. After the cables are terminated (for example, L1/L2/L3/N and PE), the bottom cable entries are resealed using waterproof sealing materials to maintain enclosure protection performance. This bottom-entry method supports reliable mechanical routing for thick/armored power cables, reduces bending stress, helps maintain orderly segregation from signal cabling, and improves on-site safety by guiding high-current cables through a controlled inlet path. Therefore, the correct cabling mode for external power cables in FusionDC1000A IT scenarios is bottom cabling.

Explanation: In the FusionDC1000A IT scenario, the power chain is built around an AC input, conditioned backup power, energy storage, and final distribution to the IT racks. Integrated UPS is the core power-conditioning component, providing voltage and frequency stabilization and uninterrupted supply during mains disturbances. The UPS works together with SmartLi, Huawei’s lithium battery system, which serves as the energy storage unit to sustain the load during outages and to support controlled shutdown or generator switchover. After UPS output, power is delivered to the IT loads through the Power PDB, which performs downstream distribution, branch protection, and organized cable termination toward rack PDUs or IT equipment feeders. By contrast, an AC/DC power system is typically associated with DC bus supply used in telecom-oriented or dedicated DC load scenarios, not the standard IT scenario architecture of FusionDC1000A that is centered on UPS plus battery plus AC distribution. Therefore, the correct components for IT scenarios are SmartLi, Power PDB, and Integrated UPS.
