AWS Certified Solutions Architect – Associate (SAA-C02) — Question 58

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?

Answer options

• A. Create an additional S3 bucket in another Region and configure cross-Region replication.
• B. Create an additional S3 bucket in another Region and configure cross-origin resource sharing (CORS).
• C. Create an additional S3 bucket with versioning in another Region and configure cross-Region replication.
• D. Create an additional S3 bucket with versioning in another Region and configure cross-origin resource (CORS).

Correct answer: C

Explanation

Option C is correct because it includes creating another S3 bucket in a different Region with versioning and implementing cross-Region replication, which complies with the disaster recovery policy. Option A lacks versioning in the new bucket, which is necessary for data recovery. Options B and D focus on cross-origin resource sharing, which is not relevant for data replication and disaster recovery needs.
