(Media files are stored in an S3 bucket in region A. Demand for the files from region B has increased. Region B is suffering from some latency issues…

Comprehensive and Detailed Explanation From Exact Extract:

To reduce latency in region B due to increased demand for media files stored in region A, cross-

region replication (CRR) should be used. CRR replicates objects to an S3 bucket in another region

(e.g., region B), allowing users to access files from a closer location, thus minimizing latency. The

WGU Cloud Deployment and Operations Study Guide (Section 2.2, S3 Replication) states, "Cross-

Region Replication in S3 copies objects to a destination bucket in a different region, reducing latency

by enabling access to data from the nearest region, such as region B in this case." S3 Batch, S3

Versioning, and Same-Region replication do not address cross-region latency.
