NCA-AIIO Question #32: Real Exam Question with Answer & Explanation

The correct answer is D: GPUDirect Storage. NVIDIA GPUDirect Storage enables direct data paths between GPU memory and local or remote storage (e.g., NVMe over fabrics), bypassing the CPU and host memory. This maximizes throughput and minimizes latency in AI data pipelines. NVLink connects GPUs, GPUDirect P2P facilitates GP

Question

What enables moving data between GPU memory and local or remote storage without using the CPU?

Options

ANVLink
BGPUDirect P2P
CInfiniBand
DGPUDirect Storage

Explanation

NVIDIA GPUDirect Storage enables direct data paths between GPU memory and local or remote storage (e.g., NVMe over fabrics), bypassing the CPU and host memory. This maximizes throughput and minimizes latency in AI data pipelines. NVLink connects GPUs, GPUDirect P2P facilitates GPU-to- GPU transfers, and InfiniBand is a network fabric, but only GPUDirect Storage targets storage access.
