AWS Certified Data Engineer Associate DEA-C01 Practice Question

An analytics company stores time-series data in an Amazon S3 bucket in us-east-1 using SSE-S3 encryption. Compliance requires that data remain accessible even if an entire AWS Region becomes unavailable, and the team must be able to recover objects that are accidentally deleted or overwritten. They want the simplest AWS-managed solution with minimal operational overhead. Which approach meets these resiliency and availability requirements?

  • Add an S3 Lifecycle rule that transitions objects to the S3 Glacier Instant Retrieval storage class after 30 days and enables Intelligent-Tiering for newer data.

  • Enable versioning on the source bucket and configure Amazon S3 Cross-Region Replication to copy objects to a versioned destination bucket in another Region.

  • Create a Multi-Region Access Point and move the data to the S3 One Zone-IA storage class in the same Region.

  • Configure Same-Region Replication with versioning to a second bucket in a different Availability Zone within us-east-1.
