Question 850
At Pinecrest Hotels, the guest-services ML team maintains demand and booking anomaly prediction under requirements for timely forecasts and protected guest attributes. Following the controlled change, the team validates: A model deployment can write arbitrary CloudWatch Logs groups because its inference IAM role includes broad administrative logging permissions. Which observed result BEST demonstrates that the correction works?
Explanation
Correct Answer
The runtime writes to the intended log stream but cannot modify an unrelated service's logging resources. This is observable proof for correction of: A model deployment can write arbitrary CloudWatch Logs groups because its inference IAM role includes broad administrative logging permissions. The approved design change is: Scope CloudWatch log actions to required resource ARNs and separate log configuration permissions from ordinary invocation needs. The Pinecrest Hotels acceptance test separates measured ML behavior from an unverified implementation claim.
Incorrect Answers
A controlled event's original prediction joins to the matching eventual label without exposing unauthorized personal identifiers. This would verify a different operation: Retain privacy-preserving stable correlation keys through prediction capture and delayed outcome ingestion. That separate action addresses: An inference monitoring workflow cannot associate captured predictions with later labels because request identifiers are stripped during processing. It cannot establish the required Pinecrest Hotels correction for: A model deployment can write arbitrary CloudWatch Logs groups because its inference IAM role includes broad administrative logging permissions. The decisive acceptance check is instead: The runtime writes to the intended log stream but cannot modify an unrelated service's logging resources.
A controlled budget threshold scenario generates the intended notice before a hard cost-cap assumption is made. This would verify a different operation: Create AWS Budgets alerts with defined cost thresholds and route notifications to the accountable ML operations owner. That separate action addresses: A budget owner discovers large GPU training overspend only after the invoice arrives because no cost threshold notification exists. It cannot establish the required Pinecrest Hotels correction for: A model deployment can write arbitrary CloudWatch Logs groups because its inference IAM role includes broad administrative logging permissions. The decisive acceptance check is instead: The runtime writes to the intended log stream but cannot modify an unrelated service's logging resources.
A tagged cost breakdown identifies the new resource responsible for the measured increase and supports an accountable remediation. This would verify a different operation: Use AWS Cost Explorer and properly applied resource tags to compare endpoint, training and storage cost changes over time. That separate action addresses: An operations team tracks aggregate monthly AWS charges but cannot isolate a sudden cost increase to new model endpoints. It cannot establish the required Pinecrest Hotels correction for: A model deployment can write arbitrary CloudWatch Logs groups because its inference IAM role includes broad administrative logging permissions. The decisive acceptance check is instead: The runtime writes to the intended log stream but cannot modify an unrelated service's logging resources.
