Question 13 of 100 | ← Chapter 1

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 ✓
• B. AWS Glue
• C. AWS Direct Connect
• D. Amazon S3 Transfer Acceleration

Correct Answer: A. AWS DataSync

Explanation

考虑到数据工程师需要将5TB的数据从本地数据中心安全传输到AmazonS3存储桶，并且每天有大约5%的数据发生变化，需要定期更新到S3存储桶，同时要求自动化传输过程并定期运行，选择AWSDataSync是最合适的服务。AWSDataSync是一个在线数据传输服务，可以简化、加速在AWS存储服务和本地存储系统之间移动大量数据的过程，同时保持数据的完整性和安全性。因此，选项A是最符合操作效率要求的选择。
