AWS Certified SysOps Administrator – Associate (SOA-C03) — Question 65

A financial services company stores customer images in an Amazon S3 bucket in the us-east-1 Region. To comply with regulations, the company must ensure that all existing objects are replicated to an S3 bucket in a second AWS Region. If an object replication fails, the company must be able to retry replication for the object.

Which solution will meet these requirements?

Answer options

• A. Configure Amazon S3 Cross-Region Replication (CRR). Use Amazon S3 live replication to replicate existing objects.
• B. Configure Amazon S3 Cross-Region Replication (CRR). Use S3 Batch Replication to replicate existing objects.
• C. Configure Amazon S3 Cross-Region Replication (CRR). Use S3 Replication Time Control (S3 RTC) to replicate existing objects.
• D. Use S3 Lifecycle rules to move objects to the destination bucket in a second Region.

Correct answer: B

Explanation

The correct answer is B because S3 Batch Replication allows for the replication of existing objects in addition to handling replication failures, which meets the company's requirements. Option A is incorrect as live replication only works for new objects, not existing ones. Options C and D do not provide the necessary retry functionality for replication failures and thus do not satisfy the requirement.
