PAS-C01 Migration Practice Question
A company is migrating an on-premises data center to AWS. The company needs to transfer 50 TB of data to Amazon S3. Which TWO AWS services can be used for this data transfer?
⚠ Common exam trap
Candidates often confuse AWS DataSync with AWS DMS or think that AWS Application Migration Service can handle bulk file transfers, but DataSync is specifically optimized for large-scale file and object transfers to S3, while Snowball Edge is the offline alternative for very large datasets.

Correct answer & explanation
✓
AWS Snowball Edge
AWS Snowball Edge is a petabyte-scale data transport solution that uses secure physical devices to transfer large amounts of data into and out of AWS. For a 50 TB migration, Snowball Edge provides a faster and more reliable option than internet-based transfers, as it avoids bandwidth limitations and long transfer times. The device is shipped to the customer, data is copied locally, and then returned to AWS for ingestion into Amazon S3.
