AWS Certified Data Engineer Associate DEA-C01 Practice Question

A company uses a multi-Region DynamoDB global table to store customer records that include personally identifiable information (PII). Privacy regulations mandate that each record must be permanently removed exactly 5 years after its creation, and the deletion must automatically propagate to every replica table without adding new compute resources. Which approach satisfies these legal requirements while keeping operational overhead and cost low?

  • Turn on DynamoDB point-in-time recovery (PITR) and set the recovery window to 5 years.

  • Periodically export the table to Amazon S3 and apply an S3 Lifecycle expiration rule that deletes objects after 5 years.

  • Schedule an EventBridge rule to invoke an AWS Lambda function daily that scans the table for items older than 5 years and deletes them.

  • Enable DynamoDB TTL and store a Unix epoch timestamp set to 5 years after each item's creation in a dedicated TTL attribute.
