Question 1150

During an NVIDIA AI factory acceptance test, engineers discover: Engineers enable maximum CPU turbo without validating sustained power and temperature under multi-GPU stress. Which TWO complementary elements are needed: the correct technical action and the strongest independent diagnostic evidence? Select TWO answers.

  1. Inspect CPU socket and PCIe mapping, negotiated lane width, NUMA bindings, BIOS changes and measured throughput.
  2. Assume a faster listed CPU clock automatically removes PCIe and NUMA locality bottlenecks from distributed training.
  3. Inspect fan tachometer and BMC sensors, GPU temperature, throttle reasons, inlet mapping and workload timing.
  4. Quarantine and diagnose affected GPUs using ECC, row-remap and diagnostic evidence before authorized repair or return.
  5. Validate Intel CPU, PCIe and NUMA placement with supported BIOS and stable sustained-power settings.
