NEW QUESTION # 25
In a large-scale water-cooled chilled water data center, how many key parameters is Huawei iCooling capable of sampling?
Answer: C
Explanation:
Option D corresponds to Huawei iCooling's specified capability of collecting operational information from more than 700 sampling points in a large-scale water-cooled chilled water data center.
Huawei iCooling is an AI-based cooling optimization system designed to reduce facility energy consumption by continuously monitoring operating conditions and dynamically adjusting cooling control strategies.
The system collects information from cooling infrastructure and analyzes 19+2 key parameters associated with system performance. This information supports intelligent coordination of cooling equipment, including chillers, pumps, cooling towers, and associated control systems.
Unlike conventional manual optimization, iCooling uses extensive data collection, data governance, dynamic model training, and real-time optimization to identify energy-efficient operating configurations.
Its algorithms can evaluate approximately 1.4 million original operating combinations within one minute to determine an appropriate cooling strategy.
Optimization is triggered by relevant operational changes, including variations in IT load or ambient temperature. For suitable water-cooled chilled water applications, Huawei identifies potential PUE improvements of approximately 8% to 15%.
The distinction between sampling points and key parameters is important. The figure of 700+ refers to sampling points, while 19+2 refers to key parameters. Therefore, D is the intended examination answer, although the question should use sampling points for technical accuracy.

NEW QUESTION # 26
An indirect evaporative cooling solution supports multiple operating modes that can switch automatically depending on cooling demand as well as the ambient temperature and humidity, in order to make the best use of natural cooling sources. Which of the following are typical operating modes?
Select all that apply
Answer: A,B,D
Explanation:
Huawei's FusionCol8000-E indirect evaporative cooling solution uses different cooling modes to adapt energy consumption to environmental conditions and the cooling requirements of the data center.
Option B, Dry mode, uses the fans and heat exchanger to transfer heat without operating the water spray system or mechanical refrigeration. It is particularly effective when outdoor conditions provide sufficient natural cooling capacity.
Option C, Spray mode, operates the fans and water spray pumps to improve heat rejection through evaporation. This mode increases cooling capacity when dry heat exchange alone cannot satisfy the cooling requirement.
Option A, Hybrid mode, combines available natural cooling with auxiliary mechanical refrigeration. The compressor supplements heat rejection when environmental conditions or IT load prevent the other modes from maintaining the required temperature.
The system selects operating modes according to cooling demand, return-air conditions, and outdoor temperature and humidity. This minimizes unnecessary compressor operation and optimizes the balance between electricity and water consumption.
Option D is not one of the three standard operating modes identified for the conventional indirect evaporative cooling configuration. Direct ventilation introduces a different airflow arrangement; Huawei also documents separate direct-ventilation configurations.
Therefore, A, B, and C are correct for the conventional solution. The instruction to Select all that apply is erroneous.

NEW QUESTION # 27
True or False: Compared with a traditional switch, the load switch used in the PowerPOD 3.0 has its width reduced by 80%.
Answer: A
Explanation:
Huawei PowerPOD 3.0 employs an innovative high-density load switch design to reduce the physical footprint of its critical power distribution architecture.
The solution uses a patented flapping-wing load switch with a compact mechanical and electrical configuration. Compared with conventional load switches, the patented design reduces switch width by approximately 80%, enabling multiple switching devices to be integrated into a smaller cabinet footprint.
This reduction is significant because traditional data center power distribution arrangements require substantial floor space for input cabinets, bypass equipment, UPS cabinets, feeder cabinets, and associated electrical components.
By integrating high-density switching technology with compact UPS power modules, PowerPOD 3.0 consolidates equipment that would otherwise occupy multiple cabinets.
Huawei's representative 2.5 MW comparison demonstrates a reduction from 21 cabinets in a conventional solution to approximately 10 cabinets in the PowerPOD 3.0 configuration. This represents a reduction of approximately 50% in the power system footprint.
The smaller switch dimensions also support a simplified physical arrangement and more efficient use of data center building space.
Option A is correct because the 80% width reduction is a specified characteristic of the patented load switch.

NEW QUESTION # 28
Which technologies does the Huawei FusionModule2000 use to lower PUE in a low-carbon environment?
Select all that apply
Answer: A,C,D
Explanation:
Huawei FusionModule2000 6.0 employs three principal energy-saving technologies to improve cooling efficiency and minimize Power Usage Effectiveness (PUE): fluorine pump refrigeration, fully adaptable compressor technology, and AI-based cooling optimization.
Option A is correct because AI optimization dynamically adjusts cooling system operation according to workload and environmental conditions. Huawei identifies approximately 8% to 15% energy savings from this optimization mechanism.
Option C is correct because fluorine pump refrigeration increases the utilization of natural cooling. When the ambient temperature falls below the specified threshold, the refrigerant pump can operate without requiring the compressor, significantly reducing refrigeration energy consumption.
Option D is correct because the fully adaptable compressor improves efficiency under partial-load conditions.
By adjusting compression characteristics, the system avoids unnecessary overcompression and reduces energy consumption.
Option B is not part of the three identified technologies. The specified natural cooling method relies on refrigerant pump operation rather than direct ventilation of outdoor air into the IT environment.
These technologies collectively contribute to FusionModule2000's low-PUE performance, particularly where outdoor conditions and variable IT loads provide opportunities for energy optimization.

NEW QUESTION # 29
Is it true or false that the standard protection rating of the FusionDC1000A is IP65?
Answer: A
Explanation:
Huawei FusionDC1000A is a prefabricated modular data center designed to operate reliably in outdoor environments. Its enclosure protection rating is a critical specification because the equipment must resist environmental exposure, including dust, rain, and other external conditions.
Option B is correct because Huawei specifies an IP55 protection rating for FusionDC1000A rather than IP65.
Ingress Protection (IP) ratings classify the level of protection provided by equipment enclosures against solid objects and water.
The first digit indicates protection against solid objects and dust. A rating of 5 indicates dust-protected construction, whereas a rating of 6 indicates a dust-tight enclosure.
The second digit describes protection against water ingress. A rating of 5 indicates protection against water jets, while a rating of 6 provides protection against more powerful water jets.
Therefore, IP65 represents a higher dust and water resistance classification than the stated IP55 rating.
Huawei combines the IP55 enclosure rating with structural and environmental design features, including Level 12 wind resistance, a stated 25-year design lifespan, and seismic performance aligned with GR-63- CORE Zone 3.
These characteristics support reliable outdoor deployment but do not change the specified enclosure rating.
Consequently, the statement that FusionDC1000A has a standard IP65 rating is false.
