Correct answer & explanation
✓
Use AWS Snowball Edge to transfer data offline
AWS Snowball Edge is a physical appliance designed for offline data transfer, making it the optimal choice for transferring a 4 TB SAP HANA database with minimal network usage. It eliminates network bandwidth consumption and avoids impacting production systems. Option A (AWS CLI with multipart upload over AWS Direct Connect) still consumes network bandwidth. Option B (AWS DataSync over the internet) also uses network bandwidth and may be slower for large datasets. Option C (AWS DMS for continuous replication) is intended for ongoing replication and would use network resources and potentially impact production.
