AWS Certified Solutions Architect – Associate (SAA-C03) — Question 718

A company has 150 TB of archived image data stored on-premises that needs to be moved to the AWS Cloud within the next month. The company’s current network connection allows up to 100 Mbps uploads for this purpose during the night only.

What is the MOST cost-effective mechanism to move this data and meet the migration deadline?

Answer options

• A. Use AWS Snowmobile to ship the data to AWS.
• B. Order multiple AWS Snowball devices to ship the data to AWS.
• C. Enable Amazon S3 Transfer Acceleration and securely upload the data.
• D. Create an Amazon S3 VPC endpoint and establish a VPN to upload the data.

Correct answer: B

Explanation

With a 100 Mbps connection limited to nighttime use, uploading 150 TB over the internet would take several months, failing to meet the one-month deadline. AWS Snowball is the most cost-effective offline transfer method for this volume of data, whereas AWS Snowmobile is designed for petabyte-scale migrations and would be excessively expensive and impractical for 150 TB. Network-based solutions like Amazon S3 Transfer Acceleration or a VPN over the existing limited connection are too slow to complete the migration within the specified timeframe.
