Question 650

During a regulated deployment assessment at a healthcare imaging provider, engineers report the following issue: A training service shows high GPU activity but throughput falls when power limiting begins. The affected work supports clinical imaging and model-assisted workflows; patient data constraints and reliable model performance are important. Which TWO responses form the best remediation-and-evidence pair? (Select TWO.)

  1. Interpret GPU compute utilization, device-memory occupancy, power draw and temperature together over time instead of using one metric as proof of efficient execution.
  2. Two isolated compatible workloads run on their assigned MIG instances with bounded resource use and documented partition capacity.
  3. Use a workload scheduler such as Slurm with explicit job GPU resource requests, queue policies and fair-share controls for shared training clusters.
  4. Correlate supported GPU error counters and Xid or ECC events with driver logs, diagnostics and affected workloads before deciding on remediation or hardware replacement.
  5. A time-series review connects kernel activity and memory use to actual completed training or inference work while checking limit events.

Explanation

Correct Answers

A:

Correct corrective action. Interpret GPU compute utilization, device-memory occupancy, power draw and temperature together over time instead of using one metric as proof of efficient execution. This fits the specific reported issue: A training service shows high GPU activity but throughput falls when power limiting begins. The corresponding failure being reduced is: High memory allocation does not necessarily mean high compute throughput, and thermal or power limits can constrain performance.

E:

Correct independent evidence. A time-series review connects kernel activity and memory use to actual completed training or inference work while checking limit events. This verifies the corrective approach for the affected clinical imaging and model-assisted workflows instead of treating an architecture diagram alone as success.

Incorrect Answers

B:

Not the most direct the action-and-evidence pair for these facts. Two isolated compatible workloads run on their assigned MIG instances with bounded resource use and documented partition capacity. This choice concerns nvidia mig hardware partitioning and isolation and may be valid in another design. But this case reports 'A training service shows high GPU activity but throughput falls when power limiting begins', which calls for reasoning about gpu utilization memory and power telemetry interpretation.

C:

Not the most direct the action-and-evidence pair for these facts. Use a workload scheduler such as Slurm with explicit job GPU resource requests, queue policies and fair-share controls for shared training clusters.

Question 651

During an industrial computer-vision rollout at a manufacturing operator, engineers report the following issue: A team treats reserved GPU memory as direct evidence of completed inference work.

  1. Use a workload scheduler such as Slurm with explicit job GPU resource requests, queue policies and fair-share controls for shared training clusters.
  2. Maintain an inventory of GPU systems, drivers, firmware, network devices and approved configuration versions with controlled rollout and reconciliation.
  3. Use nvidia-smi or supported NVIDIA management interfaces to inspect GPU identification, utilization, memory, temperatures and running processes as an initial node-level diagnostic.

Not the most direct the action-and-evidence pair for these facts. Maintain an inventory of GPU systems, drivers, firmware, network devices and approved configuration versions with controlled rollout and reconciliation. This choice concerns cluster inventory firmware and configuration baseline and may be valid in another design. But this case reports 'A training job fails sporadically and system logs include GPU Xid events', which calls for reasoning about gpu reliability events and diagnostic triage. The targeted response is: Correlate supported GPU error counters and Xid or ECC events with driver logs, diagnostics and affected workloads before deciding on remediation or hardware replacement.

D:

Not the most direct the action-and-evidence pair for these facts. An authorized VM sees the expected supported accelerator profile and passes workload and isolation tests under simultaneous tenant demand. This choice concerns virtual gpus and gpu sharing approaches and may be valid in another design. But this case reports 'A training job fails sporadically and system logs include GPU Xid events', which calls for reasoning about gpu reliability events and diagnostic triage. The targeted response is: Correlate supported GPU error counters and Xid or ECC events with driver logs, diagnostics and affected workloads before deciding on remediation or hardware replacement.

E:

Not the most direct the action-and-evidence pair for these facts. Interpret GPU compute utilization, device-memory occupancy, power draw and temperature together over time instead of using one metric as proof of efficient execution. This choice concerns gpu utilization memory and power telemetry interpretation and may be valid in another design. But this case reports 'A training job fails sporadically and system logs include GPU Xid events', which calls for reasoning about gpu reliability events and diagnostic triage. The targeted response is: Correlate supported GPU error counters and Xid or ECC events with driver logs, diagnostics and affected workloads before deciding on remediation or hardware replacement.
