Q1141. A company stores critical data in a single Amazon S3 bucket in the us-east-1 Region. Versioning is enabled on the bucket. The company needs to make the data accessible in a second AWS Region.Which solution will meet this requirement?

• A. Create a second S3 bucket in a second Region. Enable versioning on the new bucket. Enable cross- Region replication between the buckets. Use a Network Load Balancer with health checks to fail over to the secondary Region if necessary.
• B. Create an Amazon CloudFront distribution that uses the S3 bucket as an origin. Create a second S3 bucket in a second Region. Enable versioning on the new bucket. Enable cross-Region replication between the buckets. Set a high TTL on the objects.
• C. Create a second S3 bucket in a second Region.Enable versioning on the new bucket. Associate an S3 Multi-Region Access Point with both buckets.Set both buckets to active.Create a two-way replication rule between the buckets. ✓
• D. Create a second S3 bucket in a second Region. Enable versioning on the new bucket.Enable cross- Region replication between the buckets.Create an Amazon Route 53 health check based on an Amazon CloudWatch alarm for Amazon S3 latency. Fail over to the secondary Region if necessary.

Correct Answer: C. Create a second S3 bucket in a second Region.Enable versioning on the new bucket. Associate an S3 Multi-Region Access Point with both buckets.Set both buckets to active.Create a two-way replication rule between the buckets.

Explanation

The solution that will meet the requirement of making data accessible in a second AWS Region while ensuring versioning is enabled is:C. Create a second S3 bucket in a second Region. Enable versioning on the new bucket. Associate an S3 Multi-Region Access Point with both buckets. Set both buckets to active. Create a two-way replication rule between the buckets.Explanation:S3 Multi-Region Access Point: This feature allows you to simplify the management of data across multiple S3 buckets in different AWS Regions. By associating both buckets with a Multi-Region Access Point, you can seamlessly access and manage data.Two-Way Replication: Configuring a two-way replication rule enables changes made in either bucket to be replicated to the other, ensuring that both buckets stay in sync and maintain their versions.Why Other Options Are Not Suitable:A: While cross-Region replication is mentioned, the use of a Network Load Balancer for failover is unnecessary for S3, which doesn't operate in the same way as traditional servers or applications.B: Using Amazon CloudFront does provide a way to distribute content, but it does not directly address the requirement for making the data accessible in a second Region while maintaining versioning and synchronization.D: Similar to A, while cross-Region replication is useful, the addition of a Route 53 health check for failover adds complexity that is not needed for S3, which is designed for high availability and durability.Thus, option C is the most effective solution for ensuring the critical data is accessible in a second AWS Region while keeping versioning intact.
