AWS Certified Data Engineer Associate DEA-C01 Practice Question

A company ingests 5 TB of raw sensor data into an Amazon S3 bucket each day. The data must be retained for seven years, protected against accidental deletion, and remain available even if an Availability Zone fails. After the first 30 days, the data is rarely accessed. Which solution meets these requirements in the most cost-effective way?

  • Disable S3 Versioning and use S3 Batch Operations to move objects into S3 Glacier Deep Archive immediately after ingestion.

  • Enable S3 Versioning on the bucket and add a Lifecycle rule that transitions objects to S3 Glacier Instant Retrieval 30 days after creation.

  • Enable S3 Cross-Region Replication to a second bucket and transition replicated objects to S3 One Zone-IA after 30 days.

  • Move objects to S3 One Zone-IA 30 days after creation and enable S3 Object Lock in compliance mode.
