SAP-C02 Practice Question: Accelerate Workload Migration and Modernization
A company is planning to migrate 50 TB of data from on-premises to Amazon S3 over a 100 Mbps internet connection. The data is not time-sensitive and can tolerate some latency. Which migration method is MOST cost-effective and suitable?
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 devices to transfer the data.
AWS Snowball Edge is designed for large-scale data transfer when network bandwidth is limited, making it cost-effective for 50 TB over a 100 Mbps link. Option A is wrong because AWS DataSync over the internet would take very long (approximately 46 days) and is not optimal for such a large volume. Option B is wrong because S3 Transfer Acceleration improves speed via optimized routing but cannot overcome the 100 Mbps bandwidth cap; the transfer would still be slow. Option D is wrong because a 1 Gbps Direct Connect connection would be significantly more expensive than Snowball Edge, and since the data is not time-sensitive, physical shipment is more suitable.
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 DataSync over the existing internet connection.
Why it's wrong here
Slow due to bandwidth limit.
- ✗
Enable S3 Transfer Acceleration on the destination bucket.
Why it's wrong here
Does not overcome the 100 Mbps bottleneck.
- ✓
Use AWS Snowball Edge devices to transfer the data.
Why this is correct
Cost-effective for large data volumes over slow network.
- ✗
Provision a 1 Gbps AWS Direct Connect connection.
Why it's wrong here
High cost and over-provisioned for one-time transfer.
