Question 190

During an industrial computer-vision rollout at a manufacturing operator, engineers report the following issue: A design team wants to visualize and test industrial layout changes. The affected work supports factory cameras and maintenance analytics; downtime and incorrect detections can interrupt production. Choose TWO: one corrective approach and one result demonstrating it works. (Select TWO.)

  1. Plan data collection, preparation, train and validation splits, experiments and versioned artifacts before production promotion so model behavior is reproducible.
  2. Associate NVIDIA Omniverse and simulation or digital-twin workflows with designing and validating spatial industrial scenes, not with GPU health metrics or simple model-serving APIs.
  3. The trial demonstrates a relevant simulated environment and reconciles its behavior and assets with the physical process being studied.
  4. A representative run measures host-to-device transfer, allocated GPU memory and kernel execution without exceeding supported memory limits.
  5. Associate NVIDIA NeMo tooling with developing, adapting or evaluating AI models rather than with physical switch configuration or unrelated hardware maintenance.

Explanation

Correct Answers

B:

Correct corrective action. Associate NVIDIA Omniverse and simulation or digital-twin workflows with designing and validating spatial industrial scenes, not with GPU health metrics or simple model-serving APIs. This fits the specific reported issue: A design team wants to visualize and test industrial layout changes. The corresponding failure being reduced is: Choosing a text-inference runtime alone cannot replace a validated physical-world simulation workflow with scene and behavior fidelity.

C:

Correct independent evidence. The trial demonstrates a relevant simulated environment and reconciles its behavior and assets with the physical process being studied. 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:

Connect model registry versions, deployment monitoring and controlled retraining decisions in the AI lifecycle instead of assuming a one-time training job ends operations. This choice concerns production mlops deployment and feedback loop and may be valid in another design. But this case reports 'A model is evaluated against examples that also appeared in training', which calls for reasoning about ai development lifecycle data and experiment tracking. The targeted response is: Plan data collection, preparation, train and validation splits, experiments and versioned artifacts before production promotion so model behavior is reproducible.

C:

Not the most direct the action-and-evidence pair for these facts. The chosen supported model exposes the expected inference API on compatible hardware and meets the required latency and correctness smoke tests. This choice concerns nvidia nim inference microservices and may be valid in another design.
