AWS Certified Data Engineer Associate DEA-C01 Practice Question

A company ingests daily CSV files into Amazon S3 from several external partners. A data engineer must confirm that the order_date field uses the YYYY-MM-DD format and that the order_id column contains only unique values before the data is loaded into downstream pipelines. The engineer wants an automated, no-code solution that produces a concise report of any violations. Which AWS Glue DataBrew approach should the engineer use?

  • Define a ruleset with pattern and uniqueness rules and run a DataBrew ruleset evaluation job

  • Add deduplication and type-cast steps to a DataBrew recipe, then run a recipe job

  • Run a DataBrew data profile job against the dataset

  • Open the dataset in a DataBrew project and inspect the column statistics panel manually
