A company must keep a copy of all S3 objects in a second AWS region for disaster recovery and compliance. New objects must be copied automatically. What should they enable?
A) S3 Versioning only.
B) S3 Cross-Region Replication (CRR).
C) S3 Transfer Acceleration.
D) A daily manual copy via the AWS CLI.
Correct Answer: B
Explanation: S3 Cross-Region Replication automatically and asynchronously copies new objects to a bucket in another region (versioning required on both) — meeting DR and compliance needs without manual effort. (A) keeps copies in the same region. (C) speeds uploads, doesn’t replicate. (D) is manual and error-prone.
