The NetEco service program backend can be accessed through the iBMC port.
Correct Answer: B
In Huawei data center facility management,NetEcois the management software platform (server/application) used to centrally monitor and manage sites, whileiBMCis the out-of-band hardware management interface used forserver remote maintenance(such as power control, hardware health, BIOS settings, and remote console) on the specific server where iBMC exists. TheiBMC port is not a service access interface for NetEco. NetEco's backend services are accessed through theserver 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.
Question 12
The NetEco supports manual backup and automatic backup.
Correct Answer: A
NetEco is a management platform that stores critical operational data, including site configuration, device models, user/role information, historical alarms, trend data, reports, and northbound integration settings. To protect these assets and ensure service continuity, NetEco provides a built-in backup mechanism that supports bothmanualandautomaticbackup modes.Manual backupis typically used before major operations such as version upgrades, configuration changes, northbound interface adjustments, or large-scale device onboarding, so engineers can create a restore point on demand.Automatic backupis used for routine risk control and is normally implemented through scheduled tasks, allowing backups to be generated at defined intervals to reduce data-loss exposure in case of hardware failure, system corruption, or accidental misconfiguration. In standard O&M practice, automatic backups are combined with retention policies (for example, keeping a rolling set of backup files), storage capacity checks, and periodic restore verification to confirm backup integrity. This dual-mode backup capability is a foundational requirement for stable long-term operation of management systems like NetEco.
Question 13
When the outdoor unit is installed at a position higher than the indoor unit, install an oil trap every five to six meters in the vertical direction along the gas pipe to ensure system reliability.
Correct Answer: A
This statement is true. In split DX/precision cooling refrigerant systems, the "gas pipe" typically refers to thesuction linereturning refrigerant vapor (and entrained compressor oil) from the indoor evaporator to the outdoor unit/compressor. When theoutdoor unit is higher than the indoor unit, the suction line includes avertical riser. Oil naturally tends to settle and flow downward under gravity, so without proper piping measures, oil may accumulate in low points or fail to be carried upward consistently, leading topoor oil return. Insufficient oil return can cause compressor lubrication issues, abnormal noise, overheating, reduced efficiency, and long-term reliability risks. Installingoil trapsat the bottom of the riser and thenevery 5-6 metersof vertical lift helps collect oil and allows it to be periodically swept upward by refrigerant velocity, maintaining stable oil circulation. This requirement is especially important in data center cooling because continuous operation and high availability demand reliable compressor lubrication and stable refrigerant flow under varying load conditions.
Question 14
What are the colors of indicators on the LCD panel of the MDU?
Correct Answer: A,B,C
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.
Question 15
Which of the following is not a scenario-based solution for Huawei data center products?
Correct Answer: A
Huawei's scenario-based data center facility portfolio is organized around clearly defined solution families that map to typical deployment scenarios and site sizes. FusionModule500 and FusionModule2000 are smart modular data center solutions designed for standardized, fast deployment in equipment rooms and enterprise edge/branch scenarios.They integrate key subsystems such as power supply and distribution, cooling, monitoring, and optional fire protection into a modular architecture that reduces footprint and accelerates on- site delivery. Likewise, FusionDC1000 is Huawei's prefabricated modular data center series, delivered as complete, factory-integrated modules that combine civil engineering elements with electromechanical infrastructure for rapid construction, predictable quality, and scalable expansion across different capacity tiers. In contrast, FusionDC800 is not used as a defined scenario-based solution name within Huawei's mainstream data center facility solution lineup (where "FusionDC" offerings are represented by the FusionDC1000 series and "FusionModule" offerings by numbered FusionModule solutions). Therefore, FusionDC800 is the option that does not match Huawei's scenario-based solution naming.
