Flashcard Practice AWS Certified Machine Learning Engineer - Associate Multiple Choice

A company finds that validation metrics were excellent because the training set included account status updated after prediction time. What is the fix?

Choose the Best Answer

Add post-deployment monitoring and keep the current model until production drift appears. Reassign account status as a label and leave the feature-generation process unchanged. Drop account status from future models before checking whether a leakage-safe version is useful. Rebuild features with point-in-time rules, rerun validation, and retrain with leakage-safe data.
