질문 # 55
What is the material type of the heat exchanger used in Huawei's indirect evaporative cooling solution EHU?
정답：A
설명：
Huawei's Indirect Evaporative Cooling (EHU) solution incorporates a polymer heat exchanger as a principal technology for improving heat transfer efficiency, reducing water consumption, and simplifying maintenance.
Option B is correct because Huawei specifically identifies its IceCube polymer heat exchanger as a core component of the EHU cooling architecture.
Compared with conventional metal heat exchangers, the polymer design provides advantages in resistance to scaling, chemical stability, mechanical recoverability, and water quality requirements.
Traditional metal heat exchangers may experience deteriorating heat transfer performance as scale accumulates on their surfaces. They can also require more demanding water treatment and aggressive cleaning procedures that may damage metallic heat exchange fins.
Huawei's polymer heat exchanger is designed to maintain heat transfer performance while simplifying scale removal. Its material properties also allow more complex internal flow structures, including airfoil and enhanced turbulence designs.
These improvements increase convective heat transfer efficiency while reducing airflow resistance.
Huawei identifies approximately 30% water savings compared with traditional heat exchanger arrangements, supporting more sustainable cooling system operation.
Options A, C, and D do not correspond to the specified Huawei EHU heat exchanger material. Therefore, B is the correct selection.
Huawei Training Material - Supporting Extract
Core technology: polymer heat exchanger, long-lasting and efficient heat exchange, saving water by 30%.
The heat exchange efficiency is not attenuated. Not easy to scale, simple to remove scale.
Low water quality requirements. Only demineralized water is required, and the waste water rate is generally less than 10%.
High chemical stability, easy cleaning after scaling.
Improves convective heat transfer efficiency by about 5%. Reduce wind resistance by 13%.

질문 # 56
fire/accident at Data Center A caused widespread disruption to network services, including a widely used chat application and a major e-commerce platform, with outages lasting more than 24 hours. About 32,000 servers went down, affecting the services of tens of millions of users. In response, the country's president issued a public apology for the disruption to the online platforms.
Is this statement true or false?
정답：B
설명：
Option A is correct because the incident accurately reflects the major data center fire documented in Huawei's safety accident case study dated October 15, 2022.
The incident originated near lithium battery racks located in an electrical equipment room on the third basement floor of Data Center A. The facility supported major digital platforms, including communication and e-commerce services, and relied on lithium batteries for backup power.
The fire caused extensive damage to the battery installation and disrupted network services for more than 24 hours. Approximately 32,000 servers were affected, resulting in service interruptions for tens of millions of users.
The scale of the incident generated significant public and governmental concern. The country's president apologized for the disruption, while a senior official from the Ministry of Science and ICT also issued public apologies. The affected communication platform experienced additional organizational consequences.
The case illustrates the critical relationship between data center energy infrastructure and service availability.
Battery reliability, electrical protection, thermal management, monitoring systems, and emergency response procedures are essential to preventing infrastructure incidents from escalating into widespread digital service outages.
Although the investigation considered battery, rack, and electrical wiring problems, a definitive ignition cause was not established in the case study.

Consequences: Many network services, including a mainstream e-commerce platform and popular chat software, were interrupted for more than 24 hours, and 32,000 servers broke down, affecting services for tens of millions of users.
Impact: The country's president apologized to the public for the disruption to services on online platforms such as the chat software and e-commerce platform.

질문 # 57
The hardware clamping patent is one of the core technologies that enables the PowerPOD 3.0 S-ECO mode to achieve 0 ms switching from normal mode to battery mode. This technology is also referred to as the "3 zero" technology.
Which of the following descriptions are correct?
Select all that apply
정답：A,C,D
설명：
Huawei PowerPOD 3.0 uses an innovative hardware architecture incorporating patented clamping technology, an independently deployed hot-backup unit, and dedicated filtering functions to achieve uninterrupted output during transitions between operating modes.
The three-zero design addresses the timing and electrical conditions that could otherwise introduce interruptions during power transfer.
Option A represents Zero Delay. The architecture eliminates inverter startup delay and communication delay, allowing rapid transition from bypass operation to double-conversion or battery operation.
Option B represents the no-waiting characteristic. The patented hardware clamping mechanism removes the requirement to wait for abnormal mains detection or for the mains waveform to cross zero before performing the transfer. The course labels this characteristic Zero Watt, while its explanatory text describes the absence of waiting.
Option C represents Zero Current, referring to the zero-current hot-backup architecture. The independently deployed hot-backup unit maintains transfer readiness while supporting the system's high-efficiency operating mode.
Option D is incorrect because zero-voltage hot backup is not identified as one of the three-zero technologies.
The intended design ensures uninterrupted output voltage rather than requiring the backup unit to operate under a zero-voltage principle.
Together, these technologies support the specified 0 ms transfer capability while maintaining S-ECO efficiency of up to 99.1%.

Hot backup unit independently deployed to ensure transfer reliability.
Zero Watt: The system does not need to wait for the abnormal detection or the mains crosses zero.
Zero Delay: There is no inverter startup delay. No communication delay.
Zero Current: Zero current hot backup.

Verification assessment: 'Zero Watt' source heading describes no waiting; option B uses a different label.
질문 # 58
When an Energy Storage System (ESS) fire alarm activates but only smoke - not flame - is being emitted, which of the following is the correct response action?
정답：A
설명：
Smoke emission from an Energy Storage System (ESS) indicates a potentially hazardous battery condition involving overheating, internal electrical faults, or the initial development of thermal runaway. Immediate response must prioritize personnel safety, remote observation, and controlled emergency procedures.
Option B is the closest answer because it emphasizes maintaining remote observation and avoiding the immediate introduction of water into an ESS emitting smoke without visible flames.
However, personnel must not interpret this option as authorization to approach a smoking cabinet to apply water externally. Huawei's fire safety requirements explicitly prohibit approaching a smoking ESS to spray water because electrical faults and sparks may ignite combustible gases accumulated inside the enclosure.
The appropriate initial response involves evacuating personnel, raising emergency alarms, maintaining a safe distance, and remotely isolating the equipment where possible.
If visible fire develops, appropriately equipped emergency responders should implement the approved fire- extinguishing and cooling procedures in accordance with local fire authority requirements and site conditions.
Option A is unsafe because opening the enclosure may introduce oxygen and increase explosion risk. Option C describes an intervention that is not appropriate as an automatic initial response to smoke alone. Option D exposes personnel directly to thermal, electrical, and explosion hazards.
Huawei Training Material - Supporting Extract
Fire Handling Process: Quickly evacuate personnel. Call the fire department. Try to remotely shut down the equipment. Continuously monitor the equipment in a safe area. Take personal protection measures.
Precautions for Handling Fire: Do not approach an ESS that emits smoke and spray water on it; combustible gas accumulation and electrical sparks may cause explosion. The specific fire handling process must be formulated according to local fire department requirements and onsite conditions.
