질문 # 76
Which of the following models is a Huawei in-room chilled water horizontal air supply product?
정답：D
설명：
Huawei room-level air conditioning products are commonly identified by the series name plus a model suffix that indicates the cooling medium and airflow form factor. Anin-room chilled waterunit uses a chilled-water coil as the primary heat-exchange component and relies on the building's chilled-water system (chiller/plant) rather than an onboard refrigeration compressor for cooling generation. "Horizontal air supply" describes the discharge direction: the unit supplies conditioned air laterally into the room or into a specific airflow organization (such as cold-aisle delivery), supporting predictable airflow paths and stable return air conditions. Within the provided options,FusionCol5000-A050His the model that matches both identifiers: it belongs to Huawei's room cooling product line and the model code indicates an in-room configuration withchilled-watercapability andhorizontalair supply orientation. The other options belong to different series or represent configurations typically associated with other deployment forms (such as different placement, airflow direction, or system architecture). Therefore, the correct selection isFusionCol5000-A050H.
질문 # 77
During wizard startup, when you enter the screen for selecting commissioning items for the first time, all items are selected by default. Which item is mandatory. You can deselect other commissioning items that are not mandatory.
정답：C
설명：
In Huawei precision cooling commissioning, the wizard groups functional commissioning items so technicians can validate key subsystems efficiently. Thecooling system commissioningis mandatory because it verifies the primary control and protection loop that directly determines whether the unit can safely provide cooling capacity. This includes confirming the refrigeration or chilled-water cooling path can start and stop correctly, sensors and control logic are valid, and protection conditions (such as abnormal pressures
/temperatures, flow conditions, or interlocks) behave as expected. Without completing cooling-system commissioning, the unit's core purpose-stable temperature control for IT loads-cannot be assured, and the controller cannot reliably judge normal versus fault states during operation.
Other items (indoor fans, condensate pump, humidifier) are important butscenario-dependent: some sites do not use humidification, some drainage designs do not require an internal condensate pump, and fan checks can be handled as part of broader functional tests or may vary by redundancy configuration. Therefore, the wizard allows non-mandatory items to be deselected, but the cooling system commissioning must remain selected to complete a valid baseline commissioning workflow.
질문 # 78
Which of the following conditions will not cause the wizard startup commissioning to fail?
정답：D
설명：
Wizard startup commissioning is designed to verify that the unit'skey controllable subsystemscan be started, regulated, and protected correctly. Conditions that prevent a subsystem from operating normally will directly cause commissioning failure. If thecondensate pump is stuck, the drainage function cannot be validated and water may accumulate in the drain pan, which is treated as a functional fault during commissioning. Ifindoor fan 2 drive is faulty, the fan system cannot meet airflow requirements or redundancy expectations, so the fan commissioning item fails. If theelectronic expansion valve (EEV) is not opened, refrigerant flow and cooling control cannot be established, so the cooling system commissioning fails because the unit cannot build a stable refrigeration cycle or reach expected operating parameters.
In contrast, thewater leakage ropeis aprotective detection accessoryused for leak sensing and alarming. While it is important for site safety and recommended for operation, its absence typically does not block the unit from completing the functional commissioning steps for fans, cooling, and drainage; it mainly affects leak detection coverage and related alarms rather than the basic startup commissioning pass/fail.
질문 # 79
Which of the following can be used to start the inverter of the UPS5000-H?
정답：B,C
설명：
For the Huawei UPS5000-H, inverter startup is executed through theUPS's own control interfaces, which provide the "Running Control / Inv. ON" operation with the required confirmations and permissions. TheUPS LCD (MDU touchscreen)supports inverter startup through menu operations such as selecting inverter start functions and confirming the action after authentication. TheUPS WebUIalso provides the same operational control path, where an operator logs in and issues theInv. ONcommand under the UPS monitoring/running control pages. These two interfaces are part of the UPS monitoring and control design and are explicitly used for commissioning and routine O&M actions.
By contrast,ECC(data center controller) andNetEco(management platform) are mainly used for site-level monitoring, alarm collection, visualization, reporting, and centralized management. While they can display UPS status and alarms (and may integrate with UPS data), inverter startup is defined as aUPS running control operationperformed on the UPS's LCD or WebUI control plane to ensure proper authorization, safety checks, and command traceability.
질문 # 80
In Huawei's smart module solution, what is a typical benefit of remote commissioning via the ECC800-Pro app?
정답：B
설명：
The ECC800-Pro app enables remote access to commissioning functions such as device discovery, parameter configuration, and alarm verification, improving deployment efficiency and reducing the need for engineers to be physically present for every commissioning step -- while still requiring proper authentication.
