AWS Certified Solutions Architect – Associate (SAA-C02) — Question 730

A company needs to migrate a large amount of data from an on-premises storage area network (SAN) to Amazon S3. The SAN currently has 200 TB of data and is receiving an additional 20 TB of data each month. The company has a 500 Mbps connection to the internet.
What should the company do to migrate the data to Amazon S3 in the LEAST amount of time?

Answer options

• A. Use a file syncing application to sync the data to Amazon S3 over the internet through a public S3 endpoint. Sync any changed data the same way until the SAN is decommissioned.
• B. Use an AWS Snowball Edge Storage Optimized device to migrate the initial 200 TB of data to Amazon S3. Sync any changes data by using AWS DataSync until the SAN is decommissioned.
• C. Set up an AWS Site-to-Site VPN connection. Use a file syncing application to sync the data to Amazon S3 through a private S3 endpoint. Sync any changed data the same way until the SAN is decommissioned.
• D. Set up a 10 Gbps AWS Direct Connection connection. Migrate the initial 200 TB of data to Amazon S3 by using a file syncing application. Sync any changed data the same way until the SAN is decommissioned.

Correct answer: D

Explanation

Establishing a 10 Gbps AWS Direct Connection is the fastest method because it allows the 200 TB baseline transfer to complete in less than 2 days, which is quicker than the logistics, shipping, and ingestion times required for an AWS Snowball Edge device. Options A and C are limited by the slow 500 Mbps internet connection, which would take over 37 days just for the initial transfer. Therefore, provisioning the high-speed Direct Connection minimizes the overall migration time.
