Huawei HCSP-Field-Data Center Facility V1.0 H20-923_V1.0 Prüfungsfragen mit Lösungen (Q68-Q73):

68. Frage
After the battery module is installed, the torque and insulation should be checked according to the specified requirements.

Antwort: A

Begründung:
This statement is true because post-installation verification is a mandatory acceptance step for battery systems in data centers. After a battery module is installed, torque verification ensures that all power terminals, interconnect bars, and grounding points meet the specified tightening requirements. If torque is too low, contact resistance increases, which can cause abnormal heating, voltage drop, nuisance alarms, and even connector damage during high current charge/discharge. If torque is too high, threads, lugs, or busbars can be damaged, creating hidden reliability risks. Insulation testing confirms that the battery circuit has no unintended leakage paths to chassis or ground and that cable routing, connector seating, and protective covers are correct. This is especially important for lithium battery cabinets where high DC voltage and large fault current capability demand strict electrical isolation. Performing torque and insulation checks after installation reduces early-life faults, improves safety, and ensures the cabinet can pass commissioning tests and enter stable service under UPS charge/discharge control.


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

Antwort: B

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.


70. Frage
In the FusionDC1000A IT scenario, how do external input power cables typically enter the Power PDB?

Antwort: C

Begründung:
External power cables enter through dedicated bottom cable inlets on the Power PDB. After termination (L1/L2/L3/N/PE), these openings are resealed with waterproof material to preserve enclosure protection.


71. Frage
What are the colors of indicators on the LCD panel of the MDU?

Antwort: B,C,D

Begründung:
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 usesthree standard colors:green,yellow, andred.Greenindicates the UPS is operating normally and the power supply path is healthy.Yellowis 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.Redindicates 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.Orangeis not used as an MDU indicator color in this context.


72. Frage
What does PUE (Power Usage Effectiveness) measure in a data center?

Antwort: D

Begründung:
PUE = Total Facility Energy / IT Equipment Energy. A PUE closer to 1.0 indicates higher efficiency, as less energy is consumed by non-IT overhead such as cooling and power distribution losses.
