Exam NCP-AII Topic 1 Question 255 Discussion

Actual exam question for NVIDIA's NCP-AII exam
Question #: 255
Topic #: 1
You're monitoring the storage I/O for an AI training workload and observe high disk utilization but relatively low CPU utilization. Which of the following actions is LEAST likely to improve the performance of the training job?

Suggested Answer: E Vote an answer

High disk utilization and low CPU utilization indicate an 1/0 bottleneck. Switching to faster storage (A), prefetching data (B), increasing the batch size (C), and adding more RAM (D) can all help alleviate the I/O bottleneck. Reducing the number of parallel data loading threads (E) would likely worsen the bottleneck by underutilizing the available 1/0 bandwidth.
