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 DataSync
For large-scale data transfer (10 TB) to AWS, AWS DataSync (Option B) efficiently transfers data over the network with automation and optimization. AWS Snowball (Option D) is a physical device for offline transfer, ideal for large datasets when network transfer is impractical. Option A is incorrect because Amazon S3 Transfer Acceleration only speeds up S3 uploads over the internet, not a full migration service. Option C is incorrect because AWS CloudFormation is for infrastructure as code, not data transfer. Option E is incorrect because AWS DMS is for database migration, not general file transfer.
