AWS Certified Solutions Architect – Associate (SAA-C03) — Question 273

A company must migrate 20 TB of data from a data center to the AWS Cloud within 30 days. The company’s network bandwidth is limited to 15 Mbps and cannot exceed 70% utilization.

What should a solutions architect do to meet these requirements?

Answer options

• A. Use AWS Snowball.
• B. Use AWS DataSync.
• C. Use a secure VPN connection.
• D. Use Amazon S3 Transfer Acceleration.

Correct answer: A

Explanation

With a maximum network utilization of 10.5 Mbps (70% of 15 Mbps), transferring 20 TB of data over the internet would take approximately 176 days, which fails to meet the 30-day deadline. AWS Snowball provides a physical appliance to securely transport large volumes of data offline, easily fitting within the required timeframe. Online transfer methods like AWS DataSync, VPN, or Amazon S3 Transfer Acceleration are constrained by the limited network bandwidth and cannot meet the objective.
