A company stores images in an S3 bucket and needs a multi-Region strategy so it can fail over to a bucket in another Region. When an image is added to either bucket it must replicate to the other bucket within 15 minutes. Two-way replication between the buckets is enabled. Which additional steps should be taken? (Choose three.)

Correct answer: Enable S3 Replication Time Control (S3 RTC) on each replication rule., Create an S3 Multi-Region Access Point configured as active-passive., When failing over to the other Region, call the SubmitMultiRegionAccessPointRoutes operation in the AWS API..
Why this is the answer
To ensure images replicate within 15 minutes, S3 Replication Time Control (S3 RTC) must be enabled. S3 RTC provides a 15-minute replication SLA for most objects and monitors replication metrics. A Multi-Region Access Point (MRAP) is essential for a multi-Region strategy, providing a single global endpoint for accessing data across multiple buckets in different Regions. Configuring it as active-passive allows for controlled failover. When failing over, the SubmitMultiRegionAccessPointRoutes operation is used to update the routing configuration of the MRAP, directing traffic to the active bucket in the desired Region. S3 Transfer Acceleration speeds up transfers but doesn't guarantee replication time or facilitate failover. Route 53 Recovery Controller and UpdateRoutingControlStates are used for managing application routing through Route 53 health checks, which is not the primary mechanism for S3 Multi-Region Access Point failover.
