AWS Certified Solutions Architect – Associate (SAA-C02) — Question 444

A solutions architect is tasked with transferring 750 TB of data from an on-premises network-attached file system located at a branch office Amazon S3 Glacier.
The migration must not saturate the on-premises 1 Mbps internet connection.
Which solution will meet these requirements?

Answer options

• A. Create an AWS site-to-site VPN tunnel to an Amazon S3 bucket and transfer the files directly. Transfer the files directly by using the AWS CLI.
• B. Order 10 AWS Snowball Edge Storage Optimized devices, and select an S3 Glacier vault as the destination.
• C. Mount the network-attached file system to an S3 bucket, and copy the files directly. Create a lifecycle policy to transition the S3 objects to Amazon S3 Glacier.
• D. Order 10 AWS Snowball Edge Storage Optimized devices, and select an Amazon S3 bucket as the destination. Create a lifecycle policy to transition the S3 objects to Amazon S3 Glacier.

Correct answer: D

Explanation

Transferring 750 TB of data over a 1 Mbps connection is practically impossible as it would take decades, making physical transfer via AWS Snowball Edge Storage Optimized devices the only viable option. Because Snowball Edge devices do not support direct import into Amazon S3 Glacier, the data must be copied to an Amazon S3 bucket first. An S3 Lifecycle policy is then used to transition the imported data to Amazon S3 Glacier.
