The correct answer is C because the Kunpeng processor is characterized by ARM-based RISC design, multi-core capability, low power consumption, and high integration, but not by a closed architecture . The material describes Kunpeng’s strengths by stating that “The ARM architecture is used so that the same function performance occupies a smaller area of the chip, consumes less power, and are highly integrated. More hardware CPU cores are provided for better concurrent processing” and further notes that “The RISC instruction set is used. The instruction length is fixed, the addressing mode is flexible and simple, and the execution efficiency is high” . These statements directly support options A, B, and D .

From an engineering perspective, ARM-based processors are known for compact instruction design, strong concurrency through many CPU cores, and high performance per watt. Those are exactly the attributes highlighted here. By contrast, “closed architecture” is not presented as a Kunpeng feature in the training material and does not align with Huawei’s ecosystem positioning, which emphasizes compatibility across multiple operating systems and application scenarios from IoT to cloud. Therefore, C is the only option that does not describe the Kunpeng processor.
