Question
A data engineer needs to securely transfer 5 TB of data from an on-premises data center to an Amazon S3 bucket. Approximately 5% of the data changes every day. Updates to the data need to be regularly proliferated to the S3 bucket. The data includes files that are in multiple formats. The data engineer needs to automate the transfer process and must schedule the process to run periodically.
Which AWS service should the data engineer use to transfer the data in the MOST operationally efficient way?
- A. AWS DataSync Correct
- B. AWS Glue
- C. AWS Direct Connect
- D. Amazon S3 Transfer Acceleration
Explanation
AWS DataSync is designed for efficiently transferring large amounts of data between on-premises storage and Amazon S3, supporting periodic transfers and handling multiple file formats. It automates the transfer process and can be scheduled to run regularly, making it the most operationally efficient choice for this scenario.
