NEW QUESTION # 36
Which of the following are the core modules of the FusionDC1000C?
Select all that apply
Answer: A,B,C,D
Explanation:
Huawei FusionDC1000C is a prefabricated modular data center solution based on engineering productization and modular infrastructure integration. Its architecture converts major data center subsystems into standardized modules that can be manufactured, integrated, tested, and delivered according to project requirements.
Option A, the IT module, provides the infrastructure for housing computing and network equipment. Different configurations support medium- and large-scale IT deployments, with cabinet arrangements and cooling integration adapted to the required IT capacity.
Option B, the Battery module, provides energy storage infrastructure for backup power availability. Battery modules are offered in configurations supporting different installation and cooling requirements.
Option C, the Power Supply module, incorporates the electrical infrastructure necessary for distributing power to the data center. Huawei provides power modules with different capacities and transformer configurations depending on the deployment location.
Option D, the Cooling module, maintains environmental conditions for reliable IT operation. Cooling configurations include DX-based cooling and fan-wall technologies appropriate for different data center designs.
All four modules form the core FusionDC1000C architecture. Their standardized construction enables factory pre-integration, parallel onsite construction, reduced installation complexity, and faster service deployment.

NEW QUESTION # 37
Which functions are integrated into the built-in UPS unit of the FusionModule2000?
Select all that apply
Answer: A,B,D
Explanation:
Huawei FusionModule2000 incorporates an integrated UPS architecture designed to consolidate power supply and distribution functions within a compact modular data center infrastructure. The objective is to reduce equipment footprint, simplify electrical installation, and improve the efficiency of power delivery to IT and supporting cooling equipment.
Option A is correct because the integrated solution incorporates modular UPS technology, providing flexible capacity expansion and maintainable power modules. The architecture supports a high-density UPS configuration with a rated capacity of up to 180 kW per cabinet in the course's product comparison.
Option C is correct because power distribution for cooling equipment is integrated into the solution. This removes the need for a separate cooling power distribution cabinet and supports coordinated power supply to the cooling infrastructure.
Option D is correct because IT power distribution is also consolidated within the integrated UPS architecture, enabling electrical power to be supplied to server cabinets through the integrated distribution system.
Option B is incorrect because equipment room monitoring is performed by the facility monitoring and management systems rather than being one of the three principal integrated UPS power functions.
Compared with traditional arrangements requiring separate UPS, IT power distribution, and cooling distribution cabinets, the integrated design can save one to two cabinets and reduce deployment workload.

NEW QUESTION # 38
What is the general air supply mode used by a fanwall solution?
Answer: C
Explanation:
Huawei's high-temperature chilled water fan-wall solution uses horizontal air supply to deliver cooled air across IT equipment areas without requiring the underfloor air distribution infrastructure associated with conventional downflow cooling systems.
Option B is correct because the fan-wall architecture directs air horizontally through the equipment room, supporting efficient airflow distribution between cold and hot areas.
Conventional chilled water Computer Room Air Handling (CRAH) systems frequently use downward airflow into a raised-floor plenum. This arrangement requires additional construction, maintenance access, and floor- space planning.
Huawei's fan-wall solution eliminates the raised-floor requirement by providing horizontal, diffusing airflow directly into the equipment environment.
This design simplifies installation and reduces construction costs. Huawei identifies approximately 10% capital expenditure savings associated with the elimination of raised-floor infrastructure in the relevant comparison.
Horizontal airflow also supports high-temperature chilled water operation, allowing the cooling system to use higher inlet water temperatures and improving overall energy efficiency.
The architecture incorporates modular serviceable components and supports simplified maintenance from the return-air side of the equipment.
Option A does not describe the general fan-wall supply direction, while option C indicates an upward airflow arrangement not identified as the applicable solution architecture.
Therefore, B is the correct answer.

No Raised Floor, Faster and Saving Deployment, Capex reduced by 10%.
Traditional In-room CW: Under floor air flow.
Huawei Fan Wall: Fan wall: no raised floor, diffusing air flow.

NEW QUESTION # 39
Which of the following statements correctly describe the efficiency of the UPS5000-H when operating in S- ECO mode?
Select all that apply
Answer: C,D
Explanation:
Huawei UPS5000-H is a high-efficiency modular uninterruptible power supply designed for critical power applications requiring high reliability, maintainability, and reduced energy consumption.
Its Smart Economy Control Operation (S-ECO) mode improves electrical conversion efficiency while preserving uninterrupted power delivery through rapid transfer between operating modes.
Option B is correct because Huawei specifies maximum S-ECO efficiency of up to 99.1%. This performance reduces energy losses and lowers the operating expenditure associated with UPS power conversion.
Option A represents the intended high-efficiency operating range. Huawei identifies an efficiency threshold of at least 98.5% at 20% load and illustrates a high-efficiency profile across the wider operating range. However, the precise course statement uses #98.5% at 20% load, rather than establishing a strict greater-than threshold at every point between 20% and 100%.
Option C is incorrect as a maximum efficiency specification because the UPS5000-H can achieve approximately 99.1%, exceeding 98.5%.
Option D is incorrect because an efficiency exceeding 99.1% throughout the stated load range would contradict the specified maximum of 99.1%.
Accordingly, A and B are the intended examination selections, with A requiring corrected inequality wording for complete technical accuracy.

UPS5000-H Green: 96% # 99.1%. S-ECO mode, 0 ms switching. The efficiency #98.5%@20% load.

Verification assessment: 99.1% maximum and #98.5% at 20% load; the stated > threshold is imprecise.
NEW QUESTION # 40
In the fan wall solution, which of the following components support hot-swap maintenance?
Select all that apply
Answer: B,C
Explanation:
Huawei's high-temperature chilled water fan-wall solution incorporates modular serviceable electronic components to minimize cooling interruptions and reduce maintenance effort.
Option B is correct because the main control module forms part of Huawei's modular controller architecture.
It supports replacement through a plug-in design, simplifying maintenance compared with traditional fixed electrical control arrangements.
Option C is correct because the fan drive module supports hot-swappable maintenance. Separating the drive from the fan enables technicians to replace faulty drive electronics without shutting down the complete cooling unit under the supported maintenance procedure.
This capability is particularly important in high-density data centers, where cooling interruption may quickly increase IT equipment temperatures and compromise service availability.
Option A refers to the EC fan assembly itself. Although the fan is maintainable, the course distinguishes fan maintenance from the explicitly identified hot-swappable electronic modules. It does not establish that the entire EC fan assembly supports the same one-minute hot-swap operation.
Option D is ambiguously worded. The modular architecture includes a low-voltage power supply, but the question says power module. Without identifying that component as the low-voltage power supply unit, the terminology is insufficiently precise.
The intended two selections are B and C, corresponding to the named main control and fan drive modules.
The wording of D should be clarified before the question is treated as fully unambiguous.

Verification assessment: Main control and fan drive explicitly in hot-swap group; generic 'power module' is ambiguous.
