PAS-C01 Migration Practice Question
A company is migrating an SAP HANA database from on-premises to AWS. The database is 5 TB and the network link is 500 Mbps. The company has a tight window of 24 hours for the migration. Which TWO methods can be used to transfer the initial data load within the time constraint?

Correct answer & explanation
✓
Use AWS Snowball Edge to transfer the database backup files to AWS.
The correct answers are Option C (AWS Snowball Edge) and Option D (AWS DataSync over Direct Connect with compression). Snowball Edge allows physical shipment of the 5 TB database, bypassing the 500 Mbps network bottleneck entirely. DataSync with compression over Direct Connect can accelerate the transfer, potentially completing within 24 hours. Option A (AWS DMS) over 500 Mbps for 5 TB would take approximately 23 hours theoretically, but with overhead and potential retries, it may exceed the 24-hour window. Option B (AWS Site-to-Site VPN) is slower than Direct Connect and also limited by the 500 Mbps link. Option E (Amazon S3 multipart upload) faces the same network speed limitation as DMS and would likely exceed the time constraint.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use AWS DMS to perform a full load directly over the network.
Why it's wrong here
5 TB at 500 Mbps takes ~23 hours; risk of exceeding window.
- ✗
Use AWS Site-to-Site VPN with jumbo frames enabled.
Why it's wrong here
VPN adds overhead, slower than Direct Connect.
- ✓
Use AWS Snowball Edge to transfer the database backup files to AWS.
Why this is correct
Physical transfer bypasses network limitations.
- ✓
Use AWS DataSync with compression enabled over a Direct Connect link.
Why this is correct
DataSync can compress and accelerate transfer.
- ✗
Use Amazon S3 multipart upload to upload backup files directly from on-premises.
Why it's wrong here
Similar to DMS, network limited.

AWS S3 Storage Class Comparison
| Storage Class | Min Duration | Retrieval | Use Case |
|---|---|---|---|
| S3 Standard | None | Immediate | Frequently accessed data |
| S3 Standard-IA | 30 days | Immediate | Infrequent access, rapid retrieval |
| S3 One Zone-IA | 30 days | Immediate | Non-critical infrequent data |
| S3 Intelligent-Tiering | None | Immediate–hours | Unknown or changing access patterns |
| S3 Glacier Instant | 90 days | Milliseconds | Archive with instant retrieval |
| S3 Glacier Flexible | 90 days | Minutes–hours | Archive, flexible retrieval |
| S3 Glacier Deep Archive | 180 days | Hours | Long-term compliance archive |
