A company is planning to migrate a business-critical dataset to Amazon S3.The current solution design uses a single S3 bucket in the us-east-1 Region with versioning enabled to store the dataset.The company’s disaster recovery policy states that all data multiple AWS Regions.

How should a solutions architect design the S3 solution?

Create an additional S3 bucket in another Region and configure cross-Region replication.

Create an additional S3 bucket in another Region and configure cross-origin resource sharing (CORS).

Create an additional S3 bucket with versioning in another Region and configure cross-Region replication.

Create an additional S3 bucket with versioning in another Region and configure cross-origin resource (CORS).

Explanations:

While cross-Region replication is important for disaster recovery, it does not mention versioning, which is required to meet the company’s data retention policy.

Cross-origin resource sharing (CORS) is not relevant to disaster recovery; it is used for allowing web applications to make requests to different domains.

This option correctly incorporates both versioning and cross-Region replication, ensuring data is stored with version control in another region for disaster recovery.

Although this option includes versioning, CORS is not necessary for the disaster recovery policy, making it an irrelevant choice for this scenario.

    I conclude that the answer is:
    Create an additional S3 bucket with versioning in another Region and configure cross-Region replication.
