A consumer survey company has collected years of regional data in an Amazon S3 bucket in one AWS Region. The company has granted a marketing firm in a different region access to the S3 bucket. The company wants to minimize data transfer costs when the firm requests data. Which solution meets these requirements?

Correct answer: Configure the Requester Pays feature on the company’s S3 bucket..
Why this is the answer
Requester Pays buckets ensure that the requester (the marketing firm) pays for the data transfer costs, directly minimizing costs for the company. When the marketing firm accesses data from the company's S3 bucket, they will incur the data transfer out charges, not the company. Cross-Region Replication would duplicate all data, incurring storage and replication costs for the company, and the marketing firm would still pay for data transfer out from their replicated bucket. AWS Resource Access Manager shares resources but doesn't change who pays for data transfer. S3 Intelligent-Tiering optimizes storage costs, but "syncing" to another bucket implies the company would still pay for the initial data transfer out.
