AWS Certified Solutions Architect – Associate (SAA-C03) — Question 1005

A company will migrate 10 PB of data to Amazon S3 in 6 weeks. The current data center has a 500 Mbps uplink to the internet. Other on-premises applications share the uplink. The company can use 80% of the internet bandwidth for this one-time migration task.

Which solution will meet these requirements?

Answer options

• A. Configure AWS DataSync to migrate the data to Amazon S3 and to automatically verify the data.
• B. Use rsync to transfer the data directly to Amazon S3.
• C. Use the AWS CLI and multiple copy processes to send the data directly to Amazon S3.
• D. Order multiple AWS Snowball devices. Copy the data to the devices. Send the devices to AWS to copy the data to Amazon S3.

Correct answer: D

Explanation

Migrating 10 PB over an active 400 Mbps connection (80% of 500 Mbps) would take more than 6 years, making online transfer methods like AWS DataSync, rsync, or AWS CLI copy commands (Options A, B, and C) mathematically impossible to complete within the 6-week window. Using physical AWS Snowball devices (Option D) bypasses the network constraints entirely, allowing the massive dataset to be shipped and imported into Amazon S3 well within the required timeframe.
