質問 # 50
For hourly statistics reports, data of up to how many days can be queried? For monthly statistics reports, data of up to how many years can be queried?
正解：A
解説：
In Huawei NetEco statistical reporting, the query range is constrained by the report data retention policy and how summary data is stored. Forhourly statistics, the platform keeps a limited window of high-granularity data to balance storage consumption and performance. The hourly report retention is120 hours, which equals5 days. That is why hourly statistics queries are limited to5 days-beyond that window, hourly granularity is no longer retained in the report database for direct querying. For longer time horizons, NetEco relies on lower- granularity summaries (daily/weekly/monthly/yearly). Formonthly statistics, the platform supports long-term trend analysis and KPI tracking, and the maximum historical horizon aligns with the long-term statistics retention boundary used by NetEco reporting, which isup to 5 years. This design ensures fast query response, manageable database growth, and clear separation between short-term operational detail (hourly) and long- term management analysis (monthly/yearly).
質問 # 51
Which O&M practice is most effective for identifying cooling inefficiency caused by airflow problems in an operating data center?
正解：C
解説：
Huawei facility O&M methods emphasize using monitored operating data to locate inefficiencies before they become faults. Airflow-related cooling inefficiency commonly appears as hot spots at rack inlets, elevated return air temperature fluctuations, abnormal fan speed increases, or uneven temperature distribution across aisles. By trending rack inlet temperature sensors alongside cooling unit supply/return temperatures and fan speed or airflow commands, operations teams can distinguish between insufficient cooling capacity and poor airflow organization. Recirculation (hot air returning to rack inlets) often raises localized inlet temperatures without a proportional rise in room average temperature, while bypass (cold air short-circuiting back to returns) reduces cooling effectiveness and can drive fans to higher speeds unnecessarily. Data-driven checks support targeted corrective actions such as sealing cable openings, adjusting floor tile placement, restoring containment integrity, balancing airflow, or optimizing setpoints. This approach improves thermal stability, prevents overcooling, reduces energy waste, and aligns with Huawei's emphasis on integrated monitoring and closed-loop optimization for reliable, efficient operation.
質問 # 52
Which of the following interfaces is used to connect the controller and the main control module of the unit?
正解：C
解説：
In Huawei precision cooling units, the LCD controller (human-machine interface) must exchange real-time operating data and commands with the unit's main control module while also receiving a stable low-voltage power supply. This connection is typically implemented as a low-voltage communication bus plus DC power, which is why the interface is identified as I2C/12V. The I2C portion provides the data channel used for status display, parameter viewing/setting (within permission scope), alarm presentation, and command delivery (such as mute, reset, or control enable actions). The 12 V portion supplies power to the controller so it can operate independently of high-voltage power circuits and remain safe to access during routine O&M. Interfaces like DP and USB are not used as the internal control link between the HMI and the main control board in this type of unit, and "SW" is not the designated controller-to-main-board interface in the standard wiring definition. Therefore, I2C/12V is the correct selection.
質問 # 53
Video management can connect to the third-party video surveillance subsystem and play historical videos.
正解：A
解説：
In Huawei's data center O&M architecture, video is treated as an important auxiliary capability for security and remote operation. The Video Management function is designed not only to view live camera feeds, but also to integrate video resources into the same O&M workflow as alarms, access control events, and environmental monitoring. In typical deployments, the actual video storage and recording are handled by a third-party video surveillance subsystem (for example, an NVR/VMS platform). Huawei's video management function can connect to that third-party subsystem so that camera resources can be accessed in a unified interface, allowing operators to perform linkage operations such as "view video on alarm" and routine security inspection without switching platforms. Because historical recordings are stored by the surveillance subsystem, once the integration is established and permissions are correctly configured, operators can retrieve and play back historical video for event tracing, audit, and incident investigation. This supports closed-loop O&M: alarm/event occurs -> video verification -> root-cause confirmation -> maintenance action -> evidence retention.
質問 # 54
Which of the following statements are true about the routine maintenance of a UPS?
正解：B、C、D
解説：
Routine UPS maintenance is preventive by design, so it must cover both environmental conditions and equipment 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, the environment check in option A is a standard routine item.
Option B is also essential because O&M personnel must confirm the UPS is in normal 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.
