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
The correct answers are D (AWS DataSync) and E (Amazon S3 Transfer Acceleration). AWS DataSync is an online data transfer service that simplifies, automates, and accelerates moving data between on-premises storage and Amazon S3. Amazon S3 Transfer Acceleration enables fast, secure transfers of data over long distances by using AWS edge locations. Option A (AWS Direct Connect) provides a dedicated network connection but is not a data transfer service itself. Option B (Amazon Kinesis Data Firehose) is for streaming data ingestion, not for large-scale batch transfers. Option C (AWS Snowball Edge) is an offline physical device, not for network-based transfer.
