When competing with friends, which of the following statements is correct? ( )

• A.Compared with other competitors in the same industry, Huawei's network security and AI energy saving are advantages.
• B.Schneider uses CFD simulation to monitor the temperature, but the CFD software simulation technology used by Schneider is used to predict incompressible fluids. It is more accurate only when the pressure difference is less than 5%. It is not suitable for data centers. The temperature provided by Huawei Cloud map is more accurate and real-time
• C.The digital operation and maintenance of Schneider and Vertiv are both advantages. Huawei NetEco applies intelligent operation to defend against competition.
• D.Schneider can implement CPU-level energy consumption monitoring, but CPU energy consumption does not represent the energy consumption of the entire device, and monitoring is of little significance. Huawei can monitor the energy consumption of each device through rPDU, but does not monitor the CPU energy consumption.
