Flashcard Practice AWS Certified AI Practitioner Multiple Choice

A company finds that a model training dataset has inconsistent date formats and unexpected nulls. A DataBrew profile report highlights the issues. What should happen next?

Choose the Best Answer

Build or update a recipe to standardize dates, handle nulls, and validate output quality. Train the model first and use feature importance to discover which data defects mattered. Delete rows with nulls before confirming business meaning or target impact. Standardize dates manually in the output files after each training run.
