AWS Certified Solutions Architect – Associate (SAA-C02) — Question 684

A survey company has gathered data for several years from areas in the United States. The company hosts the data in an Amazon S3 bucket that is 3 TB in size and growing. The company has started to share the data with a European marketing firm that has S3 buckets. The company wants to ensure that its data transfer costs remain as low as possible.
Which solution will meet these requirements?

Answer options

• A. Configure the Requester Pays feature on the company's S3 bucket.
• B. Configure S3 Cross-Region Replication from the company's S3 bucket to one of the marketing firm's S3 buckets.
• C. Configure cross-account access for the marketing firm so that the marketing firm has access to the company's S3 bucket.
• D. Configure the company's S3 bucket to use S3 Intelligent-Tiering. Sync the S3 bucket to one of the marketing firm's S3 buckets.

Correct answer: A

Explanation

Enabling the Requester Pays feature on the Amazon S3 bucket ensures that the requester (the European marketing firm) covers the data transfer and retrieval costs associated with downloading the data. Other options like Cross-Region Replication (B) or syncing buckets (D) would cause the survey company to incur substantial data transfer and storage fees. Simply granting cross-account access (C) without configuring Requester Pays would still leave the host company responsible for all data egress charges.
