AWS Certified Data Engineer Associate DEA-C01 Practice Question

A company stores raw CSV files in an Amazon S3 bucket. Every time a new file is uploaded, the company must

  1. run an AWS Glue crawler to update the Data Catalog and
  2. start an AWS Glue ETL job only after the crawler finishes successfully. The solution must require the least custom code and automatically handle every new object. Which approach meets these requirements?

  • Create an Amazon EventBridge rule for the s3:ObjectCreated event that starts an AWS Glue workflow. In the workflow, add a conditional trigger so the ETL job runs only after the crawler succeeds.

  • Use Amazon S3 Batch Operations to invoke an AWS Glue ETL job that calls the crawler at the start of its script.

  • Configure an Amazon S3 event to invoke an AWS Lambda function that starts the crawler, waits 60 seconds, and then starts the ETL job.

  • Set up two EventBridge schedule rules: one that runs the crawler every hour and another that starts the ETL job five minutes later.
