Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use AWS Snowball Edge for the initial data transfer
The correct combination involves Snowball Edge for the initial large data transfer (A), DMS with ongoing change data capture (D), and SAP HANA system replication for zero-downtime cutover (E). Snowball Edge handles the initial bulk load efficiently. DMS captures ongoing changes during migration. SAP HANA system replication provides continuous data synchronization for a seamless switch. Option B (DataSync) is redundant as DMS already handles ongoing replication. Option C (SMS) is designed for server-level migration, not for SAP HANA data. Thus, A, D, and E are the three approaches to combine.
