AWS Certified Solutions Architect – Associate (SAA-C02) — Question 693

A company hosts an application in its own data center. The application uses Amazon S3 for data storage. The application transfers several hundred terabytes of data each month to and from Amazon S3. The company wants to minimize the cost of this data transfer.
Which solution will meet these requirements?

Answer options

• A. Create an FTPS server by using AWS Transfer Family. Configure the application to use the FTPS server to store and retrieve files.
• B. Enable S3 Transfer Acceleration on the S3 bucket. Configure the application to use the S3 Transfer Acceleration endpoint to upload and download the data.
• C. Set up an AWS Direct Connect connection between the AWS Region in use and the company's data center. Configure the application to use the Direct Connect connection to upload and download the data.
• D. Create an Amazon S3 File Gateway. Deploy the software appliance in the company's data center. Configure the application to use the S3 File Gateway to store and retrieve files.

Correct answer: A

Explanation

Using AWS Transfer Family with FTPS allows the application to securely and efficiently transfer large volumes of data directly to and from Amazon S3. This serverless transfer service streamlines ingestion and retrieval costs compared to other solutions. Alternative methods like S3 Transfer Acceleration or Direct Connect introduce additional infrastructure and per-gigabyte transfer fees that would increase overall expenses.
