NEW QUESTION # 65
Which of the following interfaces is used to connect the controller and the main control module of the unit?
Answer: B
Explanation:
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.
NEW QUESTION # 66
When a critical alarm is generated for the unit, the indicator on the LCD controller turns red and the buzzer beeps continuously.
Answer: B
Explanation:
In Huawei data center facility equipment (such as precision cooling units and related controllers), alarm presentation follows a clear severity-based design so technicians can recognize urgency immediately without entering detailed menus. Acritical alarmrepresents the highest severity level and is treated as a condition that may impact safe operation, cooling continuity, or equipment protection. For this reason, the LCD controller uses the most prominent visual and audible indications: theindicator turns redto show critical severity, and thebuzzer sounds continuouslyto ensure the alarm cannot be overlooked in a noisy equipment-room environment. This behavior supports rapid response: O&M personnel can quickly identify that immediate action is required, then open the alarm list to locate the root cause, confirm whether the unit has derated or stopped, and execute the prescribed troubleshooting steps (for example, checking power status, sensor readings, fan/compressor status, water flow/pressure, and protection interlocks). Therefore, the statement correctly describes the standard critical-alarm indication method on the LCD controller.
NEW QUESTION # 67
Which statement about gas-based fire suppression systems (e.g., FM200, Novec 1230) commonly used in data centers is correct?
Answer: B
Explanation:
Clean agent gas suppression systems work by absorbing heat or disrupting the chemical chain reaction of combustion, extinguishing fires quickly while being electrically non-conductive and leaving no residue, making them suitable for sensitive electronic environments -- unlike water- based systems.
NEW QUESTION # 68
Which of the following statements are true about the industry trend of the data center cooling systems?
Answer: A,B,C
Explanation:
As data center power density increases (especially driven by AI and high-performance computing), the industry trend is to adopt liquid cooling in high-density scenarios because liquid has much higher heat transfer capability than air, enabling stable cooling where rack power is very high. This makes statement A true. The combination of Cloud + AI pushes operators to reduce PUE and total energy cost through more intelligent control, higher efficiency cooling architectures, and integrated energy management, so statement B is also true. For large data centers, another clear trend is increasing chilled-water supply/return temperatures (higher inlet and outlet temperatures). Warmer water improves chiller efficiency, expands the number of hours that free cooling can be used, and reduces compressor work, so D is true. However, evaporative cooling is not universally the "main solution" for large data centers because it is climate- and water-condition dependent and is typically deployed as one option among multiple architectures rather than the dominant default everywhere. Therefore, C is the incorrect statement.
NEW QUESTION # 69
What is the primary reason Huawei recommends resealing bottom cable entry points with waterproof material after cabling in FusionDC1000A?
Answer: A
Explanation:
Resealing cable entry points preserves the cabinet/module's designed ingress protection level, preventing water, dust, or pest intrusion that could damage electrical components -- a critical requirement especially for outdoor or semi-outdoor prefabricated modules.
