Huawei HCSP-Field-Data Center Facility V1.0 H20-923_V1.0 Prüfungsfragen mit Lösungen (Q73-Q78):

73. 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.


74. Frage
If a component runtime overdue alarm is generated for an air conditioner, you can clear the device running time on the "Maint > Performance Maintenance" screen.

Antwort: B

Begründung:
Huawei smart cooling/precision air-conditioning controllers manage preventive maintenance by trackingaccumulated runtimefor wear components such as indoor fans, compressors (where applicable), humidifiers, and pumps. When a component reaches its configured maintenance interval, the controller generates aruntime overdue alarmto remind O&M staff to inspect, service, or replace the component. After the required maintenance action is completed (for example, fan replacement, bearing inspection, cleaning, or pump servicing), the accumulated runtime record must becleared/resetso the next maintenance cycle can be measured correctly from zero. The controller provides this function under the maintenance feature set because it is part of lifecycle management and performance tracking rather than an alarm acknowledgement. The navigation pathMaint > Performance Maintenanceis used to access runtime statistics and to clear the corresponding device/component running time after maintenance. This avoids repeated overdue alarms for a component that has already been serviced and ensures future alarms accurately reflect the operating hours of the newly serviced or replaced parts, improving reliability and maintenance planning accuracy.


75. Frage
Operators can view parameters and set parameters on the "User Settings" and "Comm Settings" menus.

Antwort: B

Begründung:
On Huawei data center cooling/monitoring controllers, menu permissions are typically organized so that routine O&M staff (operator role) can perform day-to-day adjustments that are required for normal running and integration, without accessing factory-only commissioning items. TheUser Settingsmenu is designed for operational configuration such as target temperature/humidity setpoints, control preferences, and other user- level parameters that need to be tuned to match the data hall environment and load changes. TheComm Settingsmenu is intended for communication configuration used in site integration, such as setting communication addresses, baud rates, protocol-related parameters, or enabling interfaces needed for upper- layer systems (for example, monitoring platforms). These settings are considered part of normal operation management and must be accessible so operators can maintain monitoring connectivity, replace controllers, or restore communication after changes. Higher-risk parameters (for example, factory calibration, protected control logic, or deep commissioning values) are normally restricted to higher privilege roles, but viewing and setting parameters withinUser SettingsandComm Settingsis an operator-allowed function.


76. Frage
What is the upstream input voltage range of the UPS5000-H?

Antwort: D

Begründung:
For the Huawei UPS5000-H (380/400/415 V class), "upstream input voltage range" refers to the acceptable AC mains (rectifier) line-to-line input voltage window that the UPS can tolerate while maintaining operation. Huawei specifies a wide mains input voltage range of 138?85 Vac (line voltage) to improve adaptability to weak or fluctuating power grids and to reduce unnecessary battery usage when the utility voltage sags or rises within allowable limits. Within this overall window, the UPS may apply derating rules at lower voltages (for example, full-load operation is typically guaranteed only above a higher threshold), but the upstream input can still remain connected and the UPS continues supplying the load according to its control strategy and available capacity. The other options do not match the upstream AC input range: 360?00 V is commonly associated with battery DC voltage ranges, 220?40 V is single-phase class, and
380?15 V represents rated voltage, not the full acceptable upstream range.


77. Frage
Which of the following statements are true about the routine maintenance of a UPS?

Antwort: A,B,D

Begründung:
Routine UPS maintenance is preventive by design, so it must cover bothenvironmental conditionsandequipment operating status, not only alarms. The equipment room environment directly affects UPS reliability: high temperature accelerates capacitor aging, reduces battery/rectifier reliability, and may trigger derating; improper humidity increases the risk of condensation or electrostatic discharge; dust and poor housekeeping raise the risk of blocked airflow and overheating. Therefore, theenvironment checkin option A is a standard routine item. Option B is also essential because O&M personnel must confirm the UPS is innormal operating mode, verify no hidden alarms exist in the event log, and ensure the load level is within the recommended range to maintain redundancy and efficiency. Option C is true because fans are typical
"wear-out" components; abnormal noise or speed changes often appear before a failure and can be detected early through inspection. Option D is false: absence of a front-panel alarm never replaces onsite environmental inspection and basic preventive checks.
