Question 690

During a high-traffic model-service launch at an online commerce company, engineers report the following issue: A tenant expects exclusive GPU performance from a best-effort time-sliced configuration. The affected work supports product search, recommendations and fraud screening; peak request demand makes degraded predictions visible to customers. Select TWO: the most appropriate action and the strongest verification of that action. (Select TWO.)

  1. Use NVIDIA Data Center GPU Manager to collect supported accelerator telemetry, health and diagnostic information across datacenter GPU nodes.
  2. Compare supported vGPU or time-sliced sharing, passthrough and MIG-backed virtualization according to VM isolation, licensing, performance and hardware support requirements.
  3. An authorized VM sees the expected supported accelerator profile and passes workload and isolation tests under simultaneous tenant demand.
  4. Choose supported Multi-Instance GPU profiles for multiple smaller workloads requiring hardware-partitioned compute and memory isolation, after verifying GPU and software support.
  5. A sampled node's actual firmware, GPU, driver and fabric settings match the approved inventory or show a tracked exception.

Explanation

Correct Answers

B:

Correct corrective action. Compare supported vGPU or time-sliced sharing, passthrough and MIG-backed virtualization according to VM isolation, licensing, performance and hardware support requirements. This fits the specific reported issue: A tenant expects exclusive GPU performance from a best-effort time-sliced configuration. The corresponding failure being reduced is: A sharing approach that does not meet required isolation or host compatibility can create unpredictable performance or fail to provision guest acceleration.

C:

Correct independent evidence. An authorized VM sees the expected supported accelerator profile and passes workload and isolation tests under simultaneous tenant demand. This verifies the corrective approach for the affected product search, recommendations and fraud screening instead of treating an architecture diagram alone as success.

Incorrect Answers

A:

Not the most direct the action-and-evidence pair for these facts. Use NVIDIA Data Center GPU Manager to collect supported accelerator telemetry, health and diagnostic information across datacenter GPU nodes. This choice concerns nvidia dcgm gpu fleet diagnostics and health and may be valid in another design. But this case reports 'A tenant expects exclusive GPU performance from a best-effort time-sliced configuration', which calls for reasoning about virtual gpus and gpu sharing approaches. The targeted response is: Compare supported vGPU or time-sliced sharing, passthrough and MIG-backed virtualization according to VM isolation, licensing, performance and hardware support requirements.

D:

Not the most direct the action-and-evidence pair for these facts. Choose supported Multi-Instance GPU profiles for multiple smaller workloads requiring hardware-partitioned compute and memory isolation, after verifying GPU and software support. This choice concerns nvidia mig hardware partitioning and isolation and may be valid in another design.

The targeted response is: Compare supported vGPU or time-sliced sharing, passthrough and MIG-backed virtualization according to VM isolation, licensing, performance and hardware support requirements.

E:

Not the most direct the action-and-evidence pair for these facts. A sampled node's actual firmware, GPU, driver and fabric settings match the approved inventory or show a tracked exception. This choice concerns cluster inventory firmware and configuration baseline and may be valid in another design. But this case reports 'A tenant expects exclusive GPU performance from a best-effort time-sliced configuration', which calls for reasoning about virtual gpus and gpu sharing approaches.

Question 691

During a regulated deployment assessment at a healthcare imaging provider, engineers report the following issue: A virtualization proposal ignores NVIDIA software licensing and hypervisor support.

Which action most directly addresses the described requirement?

  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. Compare supported vGPU or time-sliced sharing, passthrough and MIG-backed virtualization according to VM isolation, licensing, performance and hardware support requirements.

D:

Correct independent evidence. An authorized VM sees the expected supported accelerator profile and passes workload and isolation tests under simultaneous tenant demand. This verifies the corrective approach for the affected research training and scheduled compute allocations instead of treating an architecture diagram alone as success.

Incorrect Answers

B:

Not the most direct the action-and-evidence pair for these facts. Choose supported Multi-Instance GPU profiles for multiple smaller workloads requiring hardware-partitioned compute and memory isolation, after verifying GPU and software support. This choice concerns nvidia mig hardware partitioning and isolation and may be valid in another design. But this case reports 'A customer wants several graphics or compute VMs on one accelerator and needs a documented sharing design', which calls for reasoning about virtual gpus and gpu sharing approaches. The targeted response is: Compare supported vGPU or time-sliced sharing, passthrough and MIG-backed virtualization according to VM isolation, licensing, performance and hardware support requirements.

C:

Not the most direct the action-and-evidence pair for these facts. A point-in-time inspection identifies the correct GPU and active process, memory and temperature state corresponding to the reported issue. This choice concerns nvidia-smi point-in-time gpu operational checks and may be valid in another design. But this case reports 'A customer wants several graphics or compute VMs on one accelerator and needs a documented sharing design', which calls for reasoning about virtual gpus and gpu sharing approaches. The targeted response is: Compare supported vGPU or time-sliced sharing, passthrough and MIG-backed virtualization according to VM isolation, licensing, performance and hardware support requirements.

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 customer wants several graphics or compute VMs on one accelerator and needs a documented sharing design', which calls for reasoning about virtual gpus and gpu sharing approaches. The targeted response is: Compare supported vGPU or time-sliced sharing, passthrough and MIG-backed virtualization according to VM isolation, licensing, performance and hardware support requirements.
