A company deploys an application in two AWS Regions. The application currently uses an Amazon S3 bucket in the primary Region to store data.
A DevOps engineer needs to ensure that the application is highly available in both Regions. The DevOps engineer has created a new S3 bucket in the secondary Region. All existing and new objects must be in both S3 buckets. The application must fail over between the Regions with no data loss.
Which combination of steps will meet these requirements with the MOST operational efficiency? (Choose three.)

// explanation
A creates the necessary IAM role for S3 service principals. D establishes two-way (bidirectional) replication between buckets, ensuring both regions stay synchronized for failover capability. F uses S3 Batch Operations to replicate existing objects to the secondary bucket, complementing the CRR rule which only handles new objects.
