Huawei HCSP-Field-Data Center Facility V1.0 H20-923_V1.0 Prüfungsfragen mit Lösungen (Q89-Q94):

89. Frage
When the mains supply is stable, the UPS5000-H mainly works in which mode after ECO is configured?

Antwort: D

Begründung:
After ECO mode is enabled on the UPS5000-H, the system's control objective changes from "always supply the load through the inverter" to "maximize efficiency while keeping protection mechanisms ready." When themains input is within the configured ECO acceptance window(voltage, frequency, THD, and other quality thresholds), the UPS supplies the critical load primarily through thestatic bypass path, which has lower conversion losses than continuous double-conversion. The inverter remains synchronized and on standby, so if the mains quality deteriorates or an abnormal condition is detected, the UPS canrapidly transferthe load back to inverter operation to maintain output stability. Battery mode is only used when the rectifier/bypass source is unavailable or out of range, and maintenance bypass is a manual service path used for isolation during maintenance, not for normal energy-saving operation. Therefore, with stable utility power and ECO configured, the UPS5000-H mainly operates instatic bypass mode.


90. Frage
The NetEco service program backend can be accessed through the iBMC port.

Antwort: A

Begründung:
In Huawei data center facility management, NetEco is the management software platform (server/application) used to centrally monitor and manage sites, while iBMC is the out-of-band hardware management interface used for server remote maintenance (such as power control, hardware health, BIOS settings, and remote console) on the specific server where iBMC exists.
The iBMC port is not a service access interface for NetEco. NetEco's backend services are accessed through the server operating system network interfaces (management/service network) and corresponding application ports after the server is properly networked and configured. Even if NetEco is deployed on a Huawei server that has iBMC, iBMC only provides a channel to manage the server hardware and does not expose NetEco application access as an official commissioning/O&M path. Therefore, NetEco backend access should be planned via the site's management network (IP addressing, routing, security policy), not via iBMC.


91. Frage
After replacing the fan, choose "Menu > _____ > Performance Maintenance" on the main screen to enter the
"Performance Maintenance" screen and clear the accumulated runtime of the indoor fan.

Antwort: B

Begründung:
In Huawei room air conditioner and precision cooling unit O&M, fan replacement is treated as a maintenance activity that must be recorded in the controller so lifecycle management remains accurate. The controller tracksaccumulated runtimefor wear components such as indoor fans to support preventive maintenance planning, alarm thresholds, and performance analysis. After a fan is replaced, the old runtime value must be cleared so the system can correctly measure the new fan's service hours, avoiding premature "maintenance due" prompts or misleading reliability assessments. This function belongs to themaintenancefunction set rather than alarm viewing, parameter settings, or basic running status. Therefore, the correct navigation is throughMenu > Maint > Performance Maintenance, where the technician can locate the indoor fan runtime item and reset/clear it after confirming the replacement. Performing this step ensures consistent O&M records, supports correct maintenance intervals, and helps troubleshooting by aligning future fan-related alarms with the actual operating hours of the newly installed component.


92. Frage
What is the main function of an ATS (Automatic Transfer Switch) in a data center power architecture?

Antwort: A

Begründung:
An ATS automatically transfers the electrical load from a primary source (e.g., utility) to a secondary source (e.g., generator or backup feed) upon detecting a failure, helping maintain continuous power to critical loads.


93. Frage
ECO mode is not recommended when the load is less than

Antwort: C

Begründung:
ECO mode is designed to improve UPS efficiency by supplying the load mainly through the static bypass path when the mains is within the acceptable quality window, while keeping the inverter synchronized and ready to take over quickly if power quality degrades. However, when the load istoo light, the overall operating characteristics of the UPS system are less favorable for ECO operation. At low load levels, the benefits of ECO in reducing conversion losses are smaller, and the system becomes more sensitive to frequent transfers caused by minor mains fluctuations, which can increase transfer##and operational risk. In addition, very light loads can reduce the effectiveness of system self-check behaviors and may lead to less stable operating margins for parallel systems, power modules, and downstream distribution, depending on site conditions.
Therefore, Huawei O&M guidance sets a practical threshold and states thatECO mode is not recommended when the load is lower than 20%, helping ensure stable operation, fewer unnecessary transfers, and better overall power supply reliability for critical loads.
