9. Question 59 · 712 in bank

   A company is moving an on-premises data center to the AWS Cloud. The company must migrate 50 petabytes of file storage data to AWS with the least possible operational overhead. Which AWS service or resource should the company use to meet these requirements?

   • AAWS Snowmobile
   • BAWS Snowball Edge
   • CAWS Data Exchange
   • DAWS Database Migration Service (AWS DMS)

   Show answer

   Answer: A

   Explanation

   A. AWS Snowmobile is specifically designed for transferring large-scale data (up to 100 petabytes) from on-premises data centers to AWS. It is a physical data transport solution where a secure truck (essentially a data center on wheels) is used to transport massive amounts of data. This method minimizes operational overhead and is highly efficient for very large data migrations like the 50 petabytes mentioned. Other Options: B. AWS Snowball Edge: While AWS Snowball Edge is suitable for transferring large amounts of data (up to tens of terabytes per device), it would require hundreds of devices to transfer 50 petabytes, resulting in significantly more operational overhead compared to Snowmobile.
