Question 1
A GPU cluster commissioning engineer investigates this situation: A new GPU pod is powered on before rack inventory and PDU mapping are approved, and engineers cannot identify which chassis will lose power during maintenance. Which corrective deployment or operational action best addresses the stated problem?
Explanation
Correct Answer
For the stated NVIDIA AI infrastructure condition (A new GPU pod is powered on before rack inventory and PDU mapping are approved, and engineers cannot identify which chassis will lose power during maintenance.), this action addresses the concrete failure: Require a documented rack-to-power-to-network dependency map and signed preflight before first energization. The underlying mechanism is: AI server deployment depends on validating physical infrastructure dependencies before introducing operating system or cluster workloads. Verification would require: The staged bring-up record maps each GPU chassis to dual feeds and the controlled PDU outage leaves protected nodes powered.
Incorrect Answers
This option could be appropriate for a different NVIDIA infrastructure problem (1.1: Describe sequence of events for deployment and validation): A supplier delivers AI servers in two waves, but operators mix acceptance logs and cannot tell which batch received the corrective firmware update. The present issue is more specifically caused by: AI server deployment depends on validating physical infrastructure dependencies before introducing operating system or cluster workloads.
This option could be appropriate for a different NVIDIA infrastructure problem (1.1: Describe sequence of events for deployment and validation): A data center declares a 32-node training cluster ready because every power LED is green, although no node-to-node connectivity or GPU enumeration was tested. The present issue is more specifically caused by: AI server deployment depends on validating physical infrastructure dependencies before introducing operating system or cluster workloads.
This option could be appropriate for a different NVIDIA infrastructure problem (1.10: Validate hardware operation for workloads): A new host completes a quick matrix multiplication test but produces intermittent errors on a long mixed-precision training workload with high HBM utilization. The present issue is more specifically caused by: AI server deployment depends on validating physical infrastructure dependencies before introducing operating system or cluster workloads.
