질문 # 90
Why is early smoke detection (e.g., VESDA-type aspirating smoke detection) preferred in high- value data center environments over standard point smoke detectors?
정답：B
설명：
Aspirating smoke detection systems actively draw air samples through a network of pipes to sensitive detection chambers, identifying smoke particles at very low concentrations far earlier than standard point detectors, allowing intervention before a fire fully develops.
질문 # 91
What does a red SPD (Surge Protective Device) indicator signify?
정답：C
설명：
A red indicator means the internal protection component has degraded or disconnected after absorbing surge energy, and the SPD can no longer provide rated protection, leaving downstream loads exposed to surge risk. Immediate replacement following safe isolation procedures is required.
질문 # 92
The maintenance bypass switch cannot be turned on when the UPS5000-H works in normal mode.
정답：A
설명：
In UPS5000-H operation, normal mode means the load is supplied by the inverter, and the rectifier/charger maintains the DC link and batteries. The maintenance bypass switch (maintenance bypass breaker) is a mechanical isolation path intended to keep the load powered while the UPS is taken out of service for inspection or repair. Because it changes the power path and can create unsafe or unintended parallel paths if operated incorrectly, it is not permitted to simply close the maintenance bypass switch while the UPS is in normal mode. The correct O&M logic is to perform a controlled transfer first (typically transferring the load to static bypass with proper synchronization and confirmation that bypass power is healthy), and only then close the maintenance bypass switch so the UPS can be safely isolated. This prevents disturbance to the load, avoids synchronization/transfer hazards, and protects personnel from incorrect switching operations. Therefore, the statement is true in the sense of standard UPS5000-H operating procedure and safety interlock intent.
질문 # 93
After installing the FusionCol8000-C (110-440 kW), inject water to preserve the pressure for the chilled water pipes to how many MPa. After 30 minutes, check that no leakage occurs. Preserve the pressure for 24 hours. If the pressure drop is less than 0.01 MPa and no leakage occurs, the pipes do not leak.
정답：A
설명：
For FusionCol8000-C chilled-water systems, Huawei commissioning requires a water leakage/pressure-holding test on the chilled-water piping after installation to verify joint sealing, valve interfaces, and connection integrity before long-term operation. The specified method is to raise the water pressure in the chilled-water pipe to 0.8 MPa, then observe for 30 minutes to confirm there is no visible leakage. If the system remains dry, the same pressure is retained for
24 hours as a stability verification step. The acceptance criterion is that the pressure drop is less than 0.01 MPa over the 24-hour period and no leakage is found, which demonstrates that the piping and fittings meet tightness requirements under the prescribed test pressure. This procedure helps prevent future failures such as slow seepage, corrosion around joints, insulation waterlogging, and unexpected shutdowns caused by water loss or low differential pressure alarms. It also ensures that subsequent flushing, venting, and operational commissioning can be performed safely and reliably.
질문 # 94
The rated output capability of a single power module for the UPS5000-H is how many kVA.
정답：B
설명：
Huawei UPS5000-H is a modular UPS platform built by paralleling standardized power modules inside the power cabinet to form different system capacities. In this architecture, the "single power module" is the basic building block that contributes a fixed rated apparent power to the total UPS capacity. For the UPS5000-H series, each power module is rated at100 kVA, and the system capacity is achieved by installing multiple 100 kVA modules and configuring redundancy (such as N+1). This modular approach improves availability and O&M efficiency because a failed module can be isolated and replaced without shutting down the entire UPS, while the remaining modules continue carrying the load within their capacity limits. Using 100 kVA as the module rating also simplifies planning: technicians can quickly estimate remaining headroom by counting active modules and comparing total available kVA/kW against the real-time load, ensuring the UPS stays within recommended loading and redundancy margins during maintenance or fault conditions.
