AWS Certified DevOps Engineer – Professional (DOP-C02) — Question 256

A company runs an application that uses an Amazon S3 bucket to store images. A DevOps engineer needs to implement a multi-Region strategy for the objects that are stored in the S3 bucket. The company needs to be able to fail over to an S3 bucket in another AWS Region. When an image is added to either S3 bucket, the image must be replicated to the other S3 bucket within 15 minutes.

The DevOps engineer enables two-way replication between the S3 buckets.

Which combination of steps should the DevOps engineer take next to meet the requirements? (Choose three.)

Answer options

• A. Enable S3 Replication Time Control (S3 RTC) on each replication rule.
• B. Create an S3 Multi-Region Access Point in an active-passive configuration.
• C. Call the SubmitMultiRegionAccessPointRoutes operation in the AWS API when the company needs to fail over to the S3 bucket in the other Region.
• D. Enable S3 Transfer Acceleration on both S3 buckets.
• E. Configure a routing control in Amazon Route 53 Recovery Controller. Add the S3 buckets in an active-passive configuration.
• F. Call the UpdateRoutingControlStates operation in the AWS API when the company needs to fail over to the S3 bucket in the other Region.

Correct answer: A, B, C

Explanation

The correct steps involve enabling S3 Replication Time Control (S3 RTC) to ensure timely replication, setting up a Multi-Region Access Point for seamless access, and using the SubmitMultiRegionAccessPointRoutes operation for failover. Options D and E, while beneficial in other contexts, do not directly address the replication and failover needs outlined in the scenario.
