Question 50

During an industrial computer-vision rollout at a manufacturing operator, engineers report the following issue: Engineers confuse fine-tuning a model with serving it for predictions. 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. Distinguish training with repeated forward and backward passes and model updates from inference that applies a trained model to new inputs, and size compute for the actual phase.
  2. Identify whether a task uses explicit programmed rules, learns statistical patterns from data or belongs to a broader artificial intelligence application before selecting an ML approach.
  3. Evaluate request latency, concurrency, batching and model size together when selecting inference resources, with measurements under a representative service-level target.
  4. A controlled customization workflow records training configuration, model artifacts and evaluation outcomes using suitable model-development tooling.
  5. The plan separately estimates training memory and duration and measures inference latency or throughput using the same model family.

Explanation

Correct Answers

A:

Correct corrective action. Distinguish training with repeated forward and backward passes and model updates from inference that applies a trained model to new inputs, and size compute for the actual phase. This fits the specific reported issue: Engineers confuse fine-tuning a model with serving it for predictions. The corresponding failure being reduced is: Sizing only from an inference benchmark understates training memory and compute demands, while training-only designs can waste resources in serving.

E:

Correct independent evidence. The plan separately estimates training memory and duration and measures inference latency or throughput using the same model family. This verifies the corrective approach for the affected factory cameras and maintenance analytics instead of treating an architecture diagram alone as success.

Incorrect Answers

B:

Not the most direct the action-and-evidence pair for these facts. Identify whether a task uses explicit programmed rules, learns statistical patterns from data or belongs to a broader artificial intelligence application before selecting an ML approach. This choice concerns ai machine learning and rules-based automation and may be valid in another design. But this case reports 'Engineers confuse fine-tuning a model with serving it for predictions', which calls for reasoning about training versus inference compute requirements. The targeted response is: Distinguish training with repeated forward and backward passes and model updates from inference that applies a trained model to new inputs, and size compute for the actual phase.

C:

  2. Distinguish training with repeated forward and backward passes and model updates from inference that applies a trained model to new inputs, and size compute for the actual phase.
  3. Evaluate request latency, concurrency, batching and model size together when selecting inference resources, with measurements under a representative service-level target.
  4. Use language models and retrieval from an authorized document index when answers require natural-language interpretation plus current enterprise facts, with groundedness checks.

Explanation

Correct Answers

B:

Correct corrective action. Evaluate request latency, concurrency, batching and model size together when selecting inference resources, with measurements under a representative service-level target.

C:

Not the most direct the action-and-evidence pair for these facts. Distinguish training with repeated forward and backward passes and model updates from inference that applies a trained model to new inputs, and size compute for the actual phase. This choice concerns training versus inference compute requirements and may be valid in another design. But this case reports 'The inference server queues requests to build huge batches during low traffic', which calls for reasoning about inference latency throughput and batching tradeoffs. The targeted response is: Evaluate request latency, concurrency, batching and model size together when selecting inference resources, with measurements under a representative service-level target.

D:

Not the most direct the action-and-evidence pair for these facts. Recognize multilayer neural representation learning as deep learning within machine learning and choose it when the data and task justify the added training complexity. This choice concerns deep learning neural networks versus classical ml and may be valid in another design. But this case reports 'The inference server queues requests to build huge batches during low traffic', which calls for reasoning about inference latency throughput and batching tradeoffs. The targeted response is: Evaluate request latency, concurrency, batching and model size together when selecting inference resources, with measurements under a representative service-level target.
