The PowerCube 500 works with the intelligent network management system NMS to report fault alarms...

The correct answer is B. FALSE . The material clearly presents the PowerCube 500 as an integrated power and site support solution , not as a video transmission platform. It states that “Huawei PowerCube 500 is widely used in Safe City and Smart City solutions to house and supply power to data transmission devices, network devices, and cameras” and that “The system adopts modular design based on the integrated platform, and supports high-performance lithium batteries and intelligent NMS”

This shows that the intelligent NMS is used for site equipment and power management , such as monitoring operating state, alarms, and module conditions. The same section lists indicators for board and service status, including hardware fault, service alarm, and power-supply conditions, which supports the fault-management role of the NMS . However, the statement becomes false because it adds “real-time video data” reporting to the upper-layer NMS. PowerCube does not function as a video analytics or live video reporting platform. It supports and powers video devices, but the video streams themselves belong to camera and network service domains, not PowerCube’s NMS reporting scope. Therefore, the statement is false.
