질문 # 71
After replacing the fan, choose "Menu > _____ > Performance Maintenance" on the main screen to enter the
"Performance Maintenance" screen and clear the accumulated runtime of the indoor fan.
정답：B
설명：
In Huawei room air conditioner and precision cooling unit O&M, fan replacement is treated as a maintenance activity that must be recorded in the controller so lifecycle management remains accurate. The controller tracksaccumulated runtimefor wear components such as indoor fans to support preventive maintenance planning, alarm thresholds, and performance analysis. After a fan is replaced, the old runtime value must be cleared so the system can correctly measure the new fan's service hours, avoiding premature "maintenance due" prompts or misleading reliability assessments. This function belongs to themaintenancefunction set rather than alarm viewing, parameter settings, or basic running status. Therefore, the correct navigation is throughMenu > Maint > Performance Maintenance, where the technician can locate the indoor fan runtime item and reset/clear it after confirming the replacement. Performing this step ensures consistent O&M records, supports correct maintenance intervals, and helps troubleshooting by aligning future fan-related alarms with the actual operating hours of the newly installed component.
질문 # 72
Through device management, you can view the information about
정답：A,B,C,D
설명：
In Huawei smart module management (such as on the ECC800-Pro/WebUI), Device Management is used to centrally view and maintain managed objects (UPS, SmartLi, rPDU, sensors, air conditioners, etc.). The Overview page provides a consolidated snapshot of a device's operating status, key parameters, running mode, and basic identification information so engineers can quickly judge whether the device is healthy and online. The Alarm view lists active and historical alarms related to the device, supporting rapid fault isolation and verification after recovery. The Signal view shows monitoring points and I/O status (including analog values and digital inputs/outputs where applicable), which helps engineers confirm sensor wiring, linkage logic, and real-time state changes during commissioning and troubleshooting. The Service period information is used for lifecycle and maintenance planning, such as tracking service time, maintenance intervals, or component life indicators where supported, enabling preventive maintenance and reducing unexpected downtime. Therefore, Device Management supports viewing all four categories.
질문 # 73
The NetEco can be deployed on any virtualization platform.
정답：A
설명：
NetEco is an enterprise management application with specific runtime dependencies, including supported operating system versions, database/middleware compatibility, CPU/memory/storage requirements, and network/security prerequisites. Because of these dependencies, Huawei does not treat NetEco as "hypervisor- agnostic for any virtualization platform." In practice, NetEco deployment in virtualized environments is supported only when the virtualization stack meets Huawei's compatibility requirements, such as validated hypervisors/virtualization solutions, proper virtual hardware settings, and resource reservation rules to ensure stable performance (especially for alarm processing, historical data storage, and northbound integration tasks).
If deployed on an unverified virtualization platform, issues may occur such as clock drift, I/O latency, database performance bottlenecks, unstable NIC behavior, or unsupported VM device models, which can impact data collection, event correlation, and overall system stability. Therefore, the correct interpretation is that NetEco can be deployed onsupported/verifiedvirtualization platforms, not onanyvirtualization platform.
질문 # 74
Which of the following statements is false about the advantages of the free cooling solution for data centers?
정답：A
설명：
Free cooling is a mainstream energy-saving concept in data center cooling design, used to reduce chiller compressor runtime by leveraging low outdoor temperatures (air-side) or low cooling-water temperatures (water-side) during suitable seasons. Therefore, describing the technology as "not mature enough and should be used with caution" is the false statement when discussing its advantages. In practice, free cooling has broad industry adoption and is considered a proven approach when applied with correct engineering, such as proper filtration, anti-condensation control, heat exchanger selection, and automatic control strategies. Its advantage is that it can directly utilize the outdoor "cold source" to remove heat, which significantly reduces cooling power consumption compared with full mechanical refrigeration, improving overall energy efficiency and supporting lower PUE targets. It also makes full use of seasonal and day-night temperature differences: the system dynamically switches among free cooling, partial free cooling, and mechanical cooling to balance reliability and efficiency. The key point is maturity: the benefit of free cooling comes from well-established principles and widely implemented architectures, not experimental technology.
질문 # 75
The default address of the WAN1 port on the ECC800-Pro is
정답：B
설명：
In Huawei smart module commissioning, the ECC800-Pro controller provides a dedicated management access path through its WAN ports. For on-site startup commissioning, technicians typically connect a laptop directly toWAN1and place the laptop IP address in the same subnet as the controller so they can open the WebUI and complete initial settings (time, network, device discovery, alarm checks, linkage tests, and parameter commissioning). Thefactory default IP address for WAN1 is 192.168.8.10, which is used as the initial access point before the address is planned and changed to match the customer's management network. This default design supports quick "point-to-point" commissioning without depending on upstream switches, DHCP services, or enterprise IP planning at the very beginning of deployment. After login, Huawei commissioning practice is to harden access (password/authentication completion), then update network parameters and integrate the ECC800-Pro into the site monitoring network to enable continuous O&M, remote alarm reporting, and device management.
