SAP-C02 Practice Question: Accelerate Workload Migration and Modernization
A company wants to migrate its on-premises file server to AWS. The file server contains 10 TB of data that changes infrequently. The company has a limited bandwidth internet connection and needs to complete the migration within one week. Which AWS service should the company use for the initial data transfer?
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. This is the best option for migrating 10 TB of data over a limited bandwidth connection within a week, as it physically transfers the data via a portable storage device, bypassing the need for network bandwidth. Option A (Amazon S3 Transfer Acceleration) is incorrect because it still relies on internet bandwidth, which is insufficient for the given timeline. Option C (AWS DMS) is for database migrations, not file servers. Option D (AWS DataSync) also requires network connectivity and bandwidth, making it unsuitable for the large initial transfer over a slow connection.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Amazon S3 Transfer Acceleration
Why it's wrong here
Transfer Acceleration still requires network bandwidth and may not meet the one-week deadline.
- ✓
AWS Snowball Edge
Why this is correct
Snowball Edge is a physical device that can be shipped, bypassing bandwidth limitations.
- ✗
AWS Database Migration Service (DMS)
Why it's wrong here
DMS is designed for database migration, not file servers.
- ✗
AWS DataSync
Why it's wrong here
DataSync uses the network and would take too long with limited bandwidth.
Quick reference
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 |

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A company plans to migrate 50 on-premises virtual machines (VMs) to AWS. The migration must be completed within 2 weeks. The VMs run various operating systems and have a total data size of 10 TB. The company has a low-bandwidth internet connection (50 Mbps). Which migration approach minimizes the time to transfer the data?
easy- A.Set up an AWS Direct Connect connection to increase bandwidth
- B.Create a VPN tunnel to AWS and use rsync to copy the data
- C.Use AWS Application Migration Service to replicate the VMs continuously
- ✓ D.Use AWS Snowball Edge to transfer the VM images physically
Why D: AWS Snowball Edge is a physical device that can handle large data transfers over low-bandwidth connections. AWS Application Migration Service relies on network replication, which would be too slow. Direct Connect would require longer setup time. VPN is also network-based and slow.
