Huawei HCSP-Field-Data Center Facility V1.0 認定 H20-923_V1.0 試験問題 (Q53-Q58):

質問 # 53
Which of the following best describes the function of a Power Distribution Unit (PDU) in a smart cabinet?

A. Managing door access authentication
B. Controlling the airflow temperature setpoint
C. Detecting smoke particles
D. Distributing electrical power from the upstream source to individual IT equipment while enabling monitoring

正解：D

解説：
A PDU distributes power to rack-mounted devices; an intelligent/smart rPDU additionally provides monitoring capabilities (voltage, current, load per outlet) and can integrate with the facility monitoring system.

質問 # 54
What are the colors of indicators on the LCD panel of the MDU?

A. Yellow
B. Orange
C. Red
D. Green

正解：A、C、D

解説：
On Huawei UPS systems (such as the UPS5000 series), the MDU LCD panel includes status indicators designed to provide an immediate visual understanding of the UPS operating condition and alarm severity. The indicator system uses three standard colors: green, yellow, and red.
Green indicates the UPS is operating normally and the power supply path is healthy. Yellow is used to show abnormal conditions that require attention, such as warnings or non-critical alarms, where the UPS can typically continue supplying power but O&M personnel should inspect and handle the issue within the required timeframe. Red indicates serious or critical conditions, such as major faults or alarms that may threaten continuous power supply or require urgent action according to operating procedures. These three colors align with the common Huawei alarm severity presentation logic on the UPS display and help technicians quickly judge whether the situation is normal, warning-level, or critical-level without entering deeper menus. Orange is not used as an MDU indicator color in this context.

質問 # 55
What is the purpose of a battery management system (BMS) in a lithium-ion battery-based UPS backup?

A. Detecting unauthorized cabinet door access
B. Managing rack unit space allocation
C. Monitoring cell voltage, temperature, and state of charge to ensure safe operation and prevent thermal runaway
D. Controlling the cabinet's cooling fan speed

正解：C

解説：
A BMS continuously monitors individual cell parameters (voltage, temperature, state of charge/health) in lithium-ion battery packs, balancing cells and triggering protective actions to prevent unsafe conditions such as overcharging, overheating, or thermal runaway.

質問 # 56
Which statement about gas-based fire suppression systems (e.g., FM200, Novec 1230) commonly used in data centers is correct?

A. They extinguish fires by rapidly flooding the room with water
B. They are primarily used to cool IT equipment during normal operation
C. They suppress fire by removing heat or interrupting the combustion chemical reaction without damaging electronic equipment
D. They function only as smoke detectors

正解：C

解説：
Clean agent gas suppression systems work by absorbing heat or disrupting the chemical chain reaction of combustion, extinguishing fires quickly while being electrically non-conductive and leaving no residue, making them suitable for sensitive electronic environments -- unlike water- based systems.

質問 # 57
Which of the following are main components of Huawei indirect evaporative cooling system?

A. Water pump
B. Spray system
C. Fan
D. Air filter
E. Heat exchanger
F. Compressor

正解：A、B、C、D、E

解説：
Huawei's indirect evaporative cooling system is designed to use theoutdoor air as a "free" cold sourcewhile keeping the data hall supply air isolated from outdoor contaminants and moisture. Its core is theheat exchanger, where heat from the indoor (return) air side is transferred to the outdoor working air side without mixing the two air streams. To enhance heat removal on the outdoor side, aspray systemwets the evaporation media or spray section, and awater pumpcirculates water to maintain uniform wetting and stable evaporation performance.Fansdrive airflow through the indoor and outdoor paths to ensure sufficient heat transfer and maintain the required air volume and pressure. Because outdoor air is involved on the working-air side,air filtersare required to reduce dust and protect the heat exchanger and internal airflow channels, improving reliability and reducing maintenance. Acompressoris not a main component of indirect evaporative cooling because the system primarily relies on evaporation and heat exchange rather than mechanical refrigeration.
