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
✓
AWS Snowball Edge
AWS Snowball Edge is a physical device designed for large-scale data transfer, allowing the 2 TB SAP HANA database to be shipped to AWS, bypassing network limitations and minimizing downtime. Option B is incorrect because AWS DMS with ongoing replication is intended for continuous synchronization after initial load, not for the initial bulk transfer, and still relies on network speed. Option C is incorrect because AWS Direct Connect provides a dedicated network connection but does not eliminate transfer time for large datasets like 2 TB. Option D is incorrect because Amazon S3 Transfer Acceleration speeds up uploads over the public internet, but for 2 TB, network transfer would still be slower and less predictable than a physical device.
