Q238. A solutions architect is creating an application that stores objects in an Amazon S3 bucket. The solutions architect must deploy the application in two AWS Regions that will be used simultaneously. The objects in the two S3 buckets must remain synchronized with each other. Which combination of steps will meet these requirements with the LEAST operational overhead?(Select THREE.)

• A. Create an S3 Multi-Region Access Point. Change the application to refer to the Multi-Region Access Point ✓
• B. Configure two-way S3 Cross-Region Replication (CRR) between the two S3 buckets ✓
• C. Modify the application to store obiects in each S3 bucket
• D. Create an S3 Lifecycle rule for each S3 bucket to copy objects from one S3 bucket to the other S3 bucket
• E. Enable S3 Versioning for each S3 bucket ✓
• F. Configure an event notification for each S3 bucket to invoke an AWS Lambda function to copy objects from one S3 bucket to the other S3 bucket.

Correct Answer: A. Create an S3 Multi-Region Access Point. Change the application to refer to the Multi-Region Access Point, B. Configure two-way S3 Cross-Region Replication (CRR) between the two S3 buckets, E. Enable S3 Versioning for each S3 bucket

Explanation

Option A: Creating an S3 Multi-Region Access Point will allow the application to refer to a single endpoint for object storage, regardless of which region the objects are stored in. This eliminates the need to modify the application to store objects in each S3 bucket separately. Option B: Configuring two-way S3 Cross-Region Replication (CRR) between the two S3 buckets will ensure that any changes made to objects in one bucket are automatically replicated to the other bucket. This eliminates the need for manual synchronization of objects between the two buckets. Option E: Enabling S3 Versioning for each S3 bucket will allow the solution architect to keep track of all changes made to objects in both buckets. This ensures that any unintended changes can be rolled back easily, without the need for manual synchronization. Option C, D, and F increase operational overhead as it requires modifying the application or implementing additional processes to manually synchronize objects between the two buckets. Therefore, they are not the optimal choice for meeting the requirement with the least operational overhead.
