AWS Certified Cloud Practitioner (CLF-C02) — Question 368

A company needs to move 75 petabytes of data from its on-premises data centers to AWS.

Which AWS service should the company use to meet these requirements MOST cost-effectively?

Answer options

• A. AWS Snowball Edge Storage Optimized
• B. AWS Snowmobile
• C. AWS Direct Connect
• D. AWS Storage Gateway

Correct answer: B

Explanation

AWS Snowmobile is designed specifically for multi-petabyte to exabyte-scale data migrations, supporting up to 100 PB per vehicle, making it the most cost-effective and efficient choice for a 75 PB transfer. AWS Snowball Edge Storage Optimized would require close to a thousand individual devices, which is logistically and financially impractical. AWS Direct Connect and AWS Storage Gateway are not suitable for a rapid, cost-effective one-time offline migration of this massive scale.
