Question 510

An ML engineering team faces this production constraint: A production model was replaced unexpectedly, and compliance must find the principal who called the deployment API and when. Which action best addresses the actual requirement?

  1. Use AWS CloudTrail management event logs to identify the calling identity and model deployment change.
  2. Build a focused CloudWatch dashboard linking infrastructure and serving alarms with cost reports.
  3. Right-size the endpoint onto a supported lower-cost instance that meets measured service targets.
  4. Tune minimum serving capacity and scaling thresholds to observed burst requirements.

Explanation

Correct Answer

A:

This action fits the situation: A production model was replaced unexpectedly, and compliance must find the principal who called the deployment API and when. It implements the needed technical control: Use AWS CloudTrail management event logs to identify the calling identity and model deployment change. The intended outcome is that investigators can attribute API-level infrastructure changes to principal and time. The important limitation is that cloudTrail API events do not automatically contain every inference payload or prediction value.

Incorrect Answers

B:

This action is appropriate for another requirement: A platform team monitors training failures, endpoint errors, p95 latency, and per-project costs in separate consoles and cannot triage the end-to-end ML service quickly. It does not solve the presented constraint: A production model was replaced unexpectedly, and compliance must find the principal who called the deployment API and when. The matching action for this case is: Use AWS CloudTrail management event logs to identify the calling identity and model deployment change.

C:

This action is appropriate for another requirement: A real-time inference model consumes expensive GPU instances, but GPU metrics show low utilization and CPU benchmarks nearly meet the service objective. It does not solve the presented constraint: A production model was replaced unexpectedly, and compliance must find the principal who called the deployment API and when. The matching action for this case is: Use AWS CloudTrail management event logs to identify the calling identity and model deployment change.

D:

This action is appropriate for another requirement: A production predictor reaches its per-instance invocation target during a flash sale, and scale-out is too slow to prevent a transient queue buildup. It does not solve the presented constraint: A production model was replaced unexpectedly, and compliance must find the principal who called the deployment API and when. The matching action for this case is: Use AWS CloudTrail management event logs to identify the calling identity and model deployment change.
