Question 680

During an industrial computer-vision rollout at a manufacturing operator, engineers report the following issue: An engineer enables MIG on a GPU model whose capability was never verified. The affected work supports factory cameras and maintenance analytics; downtime and incorrect detections can interrupt production. Which TWO responses form the best remediation-and-evidence pair? (Select TWO.)

  1. An authorized operator retrieves board-level health and remote console information over the protected management network while the host OS is unavailable.
  2. Choose supported Multi-Instance GPU profiles for multiple smaller workloads requiring hardware-partitioned compute and memory isolation, after verifying GPU and software support.
  3. Compare supported vGPU or time-sliced sharing, passthrough and MIG-backed virtualization according to VM isolation, licensing, performance and hardware support requirements.
  4. Two isolated compatible workloads run on their assigned MIG instances with bounded resource use and documented partition capacity.
  5. Interpret GPU compute utilization, device-memory occupancy, power draw and temperature together over time instead of using one metric as proof of efficient execution.

Explanation

Correct Answers

B:

Correct corrective action. Choose supported Multi-Instance GPU profiles for multiple smaller workloads requiring hardware-partitioned compute and memory isolation, after verifying GPU and software support. This fits the specific reported issue: An engineer enables MIG on a GPU model whose capability was never verified. The corresponding failure being reduced is: Without a partitioning plan, tenants can contend for full-GPU resources or receive partitions too small for their model memory needs.

D:

Correct independent evidence. Two isolated compatible workloads run on their assigned MIG instances with bounded resource use and documented partition capacity. This verifies the corrective approach for the affected factory cameras and maintenance analytics instead of treating an architecture diagram alone as success.

Incorrect Answers

A:

Not the most direct the action-and-evidence pair for these facts. An authorized operator retrieves board-level health and remote console information over the protected management network while the host OS is unavailable. This choice concerns bmc and out-of-band server health administration and may be valid in another design. But this case reports 'An engineer enables MIG on a GPU model whose capability was never verified', which calls for reasoning about nvidia mig hardware partitioning and isolation.

C:

E:

Question 681

During a security and capacity review at a financial analytics firm, engineers report the following issue: The cluster requires dedicated slices but all jobs currently compete for the same complete device. The affected work supports risk scoring and historical-data models; traceable controls and predictable throughput are required. Which action most directly addresses the described requirement?

  1. Correlate supported GPU error counters and Xid or ECC events with driver logs, diagnostics and affected workloads before deciding on remediation or hardware replacement.
  2. Use appropriate NVIDIA GPU drivers, device discovery or GPU Operator components and Kubernetes resource requests so eligible workloads receive supported accelerator devices.
  3. Choose supported Multi-Instance GPU profiles for multiple smaller workloads requiring hardware-partitioned compute and memory isolation, after verifying GPU and software support.
  4. Compare supported vGPU or time-sliced sharing, passthrough and MIG-backed virtualization according to VM isolation, licensing, performance and hardware support requirements.

Question 682

During a security and capacity review at a financial analytics firm, engineers report the following issue: The cluster requires dedicated slices but all jobs currently compete for the same complete device. The affected work supports risk scoring and historical-data models; traceable controls and predictable throughput are required. Which acceptance result is most relevant to this workload?

  1. Two isolated compatible workloads run on their assigned MIG instances with bounded resource use and documented partition capacity.
  2. A deliberately observed GPU condition appears in DCGM telemetry with node and device identity and leads to an actionable diagnostic record.
  3. An authorized VM sees the expected supported accelerator profile and passes workload and isolation tests under simultaneous tenant demand.
  4. A point-in-time inspection identifies the correct GPU and active process, memory and temperature state corresponding to the reported issue.

Question 683

During a regional deployment expansion at a media technology business, engineers report the following issue: A scheduling plan assumes MIG profiles can be changed without affecting active dependent jobs.

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.

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.

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.

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. 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.

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. 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.
