Free NVIDIA NCP-AII Exam Questions

Question 1

After running a 24-hour stress test on a DGX node, the administrator should verify which two keymetrics to ensure system stability?

A : Average CPU usage >80% and Docker container uptime.

B : No thermal throttling events and consistent GPU utilization >95% throughout the test.

C : SSD write endurance and RAM capacity.

D : Total energy consumption and NVLink bandwidth.

Answer: B

Question 2

During East-West fabric validation on a 64-GPU cluster, an engineer runs all_reduce_perf andobserves an algorithm bandwidth of 350 GB/s and bus bandwidth of 656 GB/s. What does thisindicate about the fabric performance?

A : Inconclusive; rerun with point-to-point tests.

B : Optimal performance; bus bandwidth near theoretical peak for NDR InfiniBand.

C : Critical failure; bus bandwidth exceeds hardware capabilities.

D : Suboptimal performance; algorithm bandwidth should match bus bandwidth.

Answer: B
