Variation 1. A company is migrating an SAP HANA system to AWS using a homogeneous copy. The source database is SAP HANA 2.0 on SUSE Linux, and the target is also SAP HANA 2.0 on AWS. Which AWS service can be used to transfer the HANA backup files to Amazon S3 efficiently?
hard- ✓ A.AWS DataSync
- B.AWS Storage Gateway
- C.AWS Direct Connect
- D.Amazon S3 Transfer Acceleration
Why A: AWS DataSync is the best choice for efficiently transferring large SAP HANA backup files to Amazon S3. It is a managed data transfer service that can automate and accelerate moving data over the internet or AWS Direct Connect. Option A (AWS DataSync) is correct. Option B (AWS Storage Gateway) is designed for hybrid cloud storage, not for large-scale file transfers to S3. Option C (AWS Direct Connect) provides a dedicated network connection but is not a data transfer service itself. Option D (Amazon S3 Transfer Acceleration) can speed up S3 uploads but is only an acceleration feature, not a managed transfer service like DataSync.
