NVIDIA NCA-AIIO Exam With Confidence Using Practice Dumps

Training is the deep learning phase that benefits most from a multi-node architecture. It involves compute-intensive operations—forward and backward passes, gradient computation, and synchronization—across large datasets and complex models. Distributing these tasks across multiple nodes with GPUs accelerates processing, reduces time to convergence, and enables handling models too large for a single node. While data augmentation and inference can leverage multiple nodes, their gains are less pronounced, as they typically involve lighter or more localized computation.

GPU utilization is defined as the percentage of time the GPU’s compute engines are actively processing data, reflecting its workload intensity over a period (e.g., via nvidia-smi). It’s distinct from memory usage (a separate metric), core counts, or maximum runtime, providing a direct measure of compute activity.

The correct answer is A because memory-transfer bottlenecks are addressed by GPU memory-system features such as high-bandwidth memory, shared memory, cache, and high-bandwidth interconnects or buses. NVIDIA’s Blackwell tuning guide describes the GPU memory system and states that the NVIDIA B200 GPU supports HBM3 and HBM3e high-bandwidth memory with capacity up to 180 GB. NVIDIA’s CUDA tuning documentation also describes shared memory as an important architectural resource available per streaming multiprocessor, which helps reduce slower memory traffic when used effectively.

Why the other options are incorrect: GPUs are not normally wired as main disk controllers. Increasing generic PCIe I/O ports does not directly solve simulation memory-transfer bottlenecks inside GPU execution. Dedicated inference ASICs are not the general NVIDIA GPU architectural feature used to address memory-transfer performance in simulation workloads.
