SAP-C02 Practice Question: Accelerate Workload Migration and Modernization
A company is planning to migrate 50 TB of data from an on-premises data center to Amazon S3. The on-premises network bandwidth is 100 Mbps. The migration must be completed within 30 days. What is the most cost-effective solution?
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
✓
Use AWS Snowball Edge device.
At 100 Mbps, transferring 50 TB over the internet would take approximately 50 days (50*8*1024*1024 / (100*86400) ≈ 48.5 days), exceeding the 30-day window. AWS Snowball Edge is a physical device that can transfer data offline faster and is cost-effective for large data volumes. AWS DMS is for databases; Direct Connect requires setup time; S3 Transfer Acceleration improves speed but still limited by bandwidth.
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 Direct Connect to increase bandwidth.
Why it's wrong here
Direct Connect can take weeks to provision and adds monthly costs, not the most cost-effective for a one-time migration.
- ✓
Use AWS Snowball Edge device.
Why this is correct
Snowball Edge can transfer 50 TB in a few days, meeting the deadline cost-effectively.
- ✗
Use AWS DataSync over the internet.
Why it's wrong here
DataSync would still be limited by the 100 Mbps bandwidth, taking too long.
- ✗
Use AWS Database Migration Service (AWS DMS).
Why it's wrong here
DMS is for database migration, not file data.

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 |

Variation 1. A company wants to migrate 500 TB of data from an on-premises data center to Amazon S3. The company has a 1 Gbps dedicated network connection to AWS. What is the most cost-effective and time-efficient migration method?
easy- ✓ A.Use AWS Snowball Edge to physically ship the data to AWS.
- B.Use S3 Transfer Acceleration to upload data over the existing internet connection.
- C.Use AWS DataSync to transfer data over the dedicated network.
- D.Establish an AWS Direct Connect connection and use S3 multipart upload.
Why A: AWS Snowball Edge is the most cost-effective and time-efficient method for migrating 500 TB of data over a 1 Gbps dedicated connection. At 1 Gbps, the theoretical maximum transfer time for 500 TB is over 46 days, not accounting for overhead and network issues. Snowball Edge physically ships the data, avoiding network transfer delays. Option B is wrong because S3 Transfer Acceleration still uses the network and does not reduce the transfer time sufficiently for 500 TB. Option C is wrong because AWS DataSync is optimized for smaller, ongoing transfers and would still be limited by the 1 Gbps link. Option D is wrong because Direct Connect provides a dedicated network connection but still requires transferring data over the network, which would take many days.
