AWS Certified Solutions Architect – Professional — Question 486

A company that develops consumer electronics with offices in Europe and Asia has 60 TB of software images stored on premises in Europe. The company wants to transfer the images to an Amazon S3 bucket in the ap-northeast-1 Region. New software images are created daily and must be encrypted in transit. The company needs a solution that does not require custom development to automatically transfer all existing and new software images to Amazon S3.
What is the next step in the transfer process?

Answer options

• A. Deploy an AWS DataSync agent and configure a task to transfer the images to the S3 bucket
• B. Configure Amazon Kinesis Data Firehose to transfer the images using S3 Transfer Acceleration
• C. Use an AWS Snowball device to transfer the images with the S3 bucket as the target
• D. Transfer the images over a Site-to-Site VPN connection using the S3 API with multipart upload

Correct answer: A

Explanation

AWS DataSync is the ideal service for this scenario as it automates, accelerates, and encrypts data transfers between on-premises storage and Amazon S3 without requiring custom development. While AWS Snowball is suitable for one-time large migrations, it cannot automatically sync daily new images. Using Kinesis Data Firehose or S3 API multipart uploads over a VPN would require custom scripting and integration, which violates the requirement for a no-custom-development solution.
