A company seeks a serverless solution to analyze data stored in an Amazon S3 bucket, requiring encryption and cross-region replication with minimal operational overhead. Which approach best meets these criteria?
Explanation:
The correct answer is A. This option meets all requirements of the company with the least operational overhead. Creating a new S3 bucket and using S3 Cross-Region Replication (CRR) ensures the data is replicated to another region. Using server-side encryption with AWS KMS multi-Region keys (SSE-KMS) provides the required encryption. Additionally, Amazon Athena allows for serverless querying of the data, making it an efficient choice for analyzing existing and new data in a serverless environment.
