Question 1

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

Question 2

A : ngc config get

B : ngc init

C : ngc config set

D : ngc config update

Answer: C

Question 3

After NCCL burn-in reports "transport retry count exceeded," which corrective action addresses theunderlying fabric issue?

A : Switch from Ring to Tree algorithms via NCCL_ALGO=TREE

B : Reduce message size to decrease network utilization

C : Increase NCCL_IB_TIMEOUT to tolerate longer latencies

D : Inspect InfiniBand link quality metrics (BER, symbol errors) and replace faulty cables

Answer: D

Question 4
