Question 750
The acceptance reviewer at Beacon Health Network needs independent proof of the correction to this reported ML problem: A deployment pipeline grants its Cloud Build runner unrestricted storage and IAM administrator rights for convenience. Which independently observable result best verifies that the remediation works?
Explanation
Correct Answer
An unauthorized role-change simulation is denied while an approved signed release completes. This controlled observation specifically validates the proposed remedy: Give the build identity the minimum build, artifact, and deployment roles required and separate release privileges. It addresses the documented failure at Beacon Health Network: A deployment pipeline grants its Cloud Build runner unrestricted storage and IAM administrator rights for convenience.
Incorrect Answers
Historical alert replay stays within the compute budget while materially degraded cases still trigger review. This is evidence for a different corrective change: Apply drift severity, expected value, and budget thresholds with cooldowns before scheduling retraining. That other change addresses: A continuous training system retrains after every minor drift alert and costs far more than the model's economic benefit. It does not validate the specific Beacon Health Network remediation for: A deployment pipeline grants its Cloud Build runner unrestricted storage and IAM administrator rights for convenience. The necessary check instead is: An unauthorized role-change simulation is denied while an approved signed release completes.
An injected subgroup quality regression pauses the traffic ramp despite healthy endpoint error counts. This is evidence for a different corrective change: Gate canary ramp-up on multiple quality, safety, fairness, and performance thresholds with automatic halt. That other change addresses: A canary deployment gradually degrades fairness and latency but traffic expansion continues because promotion checks only error rate. It does not validate the specific Beacon Health Network remediation for: A deployment pipeline grants its Cloud Build runner unrestricted storage and IAM administrator rights for convenience. The necessary check instead is: An unauthorized role-change simulation is denied while an approved signed release completes.
A replay shows scheduled retraining only when adequate fresh labeled data exists and quality gates pass. This is evidence for a different corrective change: Choose a retraining cadence based on outcome-label availability, drift evidence, and justified business update frequency. That other change addresses: A relatively stable demand model is retrained every hour despite labels arriving monthly, wasting compute and propagating noise. It does not validate the specific Beacon Health Network remediation for: A deployment pipeline grants its Cloud Build runner unrestricted storage and IAM administrator rights for convenience. The necessary check instead is: An unauthorized role-change simulation is denied while an approved signed release completes.
