The statement is FALSE because it attributes guarantees for CPU, memory, and I/O resources collectively to CPU QoS.

CPU QoS applies to the allocation and scheduling of CPU computing resources. Memory and I/O are distinct resource classes and are controlled through their own resource-management mechanisms. A CPU QoS policy cannot by itself guarantee the VM ' s minimum memory allocation and storage/network I/O resources.

Huawei ' s FusionCompute architecture explicitly separates compute virtualization management, storage virtualization management, and network virtualization management, reflecting the fact that these resource domains are managed independently. The Lab Guide likewise demonstrates separate resource reservation parameters for CPU and memory, configuring “Reserved CPU (%)” and “Reserved Memory (%)” independently rather than treating memory as part of CPU QoS.

FusionCube combines compute, virtualization, networking, and scale-out storage into a unified platform, but convergence does not eliminate the distinction between their QoS controls.

Therefore, CPU QoS can protect or regulate CPU computing capability, but it does not independently guarantee CPU, memory, and I/O resources together. The overall statement is consequently FALSE.
