Huawei Ocean Protect Appliance adopts the key technology of CPU core grouping and intelligent scheduling,...

The Huawei Ocean Protect Appliance leverages CPU core grouping and intelligent scheduling to optimize performance, as described in the *HCIP-Storage V5.5 Training Material (Module 2: Flash Storage Technologies)*. The material states: “CPU core grouping and intelligent scheduling in Ocean Protect appliances enable physical and logical isolation of resources, ensuring that specific cores are dedicated to specific tasks. This isolation reduces contention and minimizes latency for critical operations.” This directly supports option C, as the technology’s primary advantage is reducing latency through resource isolation.

- Option A: Incorrect. While load balancing is a feature of some Huawei storage systems, the training material does not specify that CPU core grouping and intelligent scheduling in Ocean Protect appliances focus on distributing jobs for load balancing. Instead, it emphasizes resource isolation.

- Option B: Incorrect. The material indicates that this technology prevents core overload by isolating tasks, avoiding high latency, making this statement false.

- Option D: Incorrect. Prefetching data and metadata to improve cache hit ratios is unrelated to CPU core grouping and scheduling, which focus on processor resource management, not cache operations.

Thus, option C is the correct advantage of this technology.
