You must deploy an application across two AWS Regions simultaneously and keep the objects in the two S3 buckets synchronized. Choose the combination of steps that meets the requirement with the LEAST operational overhead. (Choose three.)

To minimize operational overhead while synchronizing S3 buckets across two regions, you need to leverage native S3 features. Enabling S3 Versioning on both buckets is a prerequisite for Cross-Region Replication (CRR), ensuring object versions are maintained. Configuring two-way CRR automatically replicates objects and their metadata between the specified buckets, handling new objects, updates, and deletes with minimal manual intervention. Finally, creating an S3 Multi-Region Access Point provides a single global endpoint for your application to access the S3 buckets in both regions, automatically routing requests to the closest healthy bucket, simplifying application logic and improving performance. Modifying the application to store objects separately increases complexity. S3 Lifecycle rules are for object transitions or expirations, not real-time replication. S3 event notifications with Lambda introduce custom code and additional operational overhead compared to native CRR.
