This SAP-C02 practice question tests your understanding of accelerate workload migration and modernization. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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?
Use AWS DataSync over the existing internet connection.
Why wrong: Slow due to bandwidth limit.
Enable S3 Transfer Acceleration on the destination bucket.
Why wrong: Does not overcome the 100 Mbps bottleneck.
Use AWS Snowball Edge devices to transfer the data.
Cost-effective for large data volumes over slow network.
Provision a 1 Gbps AWS Direct Connect connection.
Why wrong: High cost and over-provisioned for one-time transfer.
Answer choices
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.
Option C is correct because AWS Snowball Edge is cost-effective for large data volumes over slow connections. Option A is wrong because AWS Direct Connect is expensive and not justified. Option B is wrong because AWS DataSync over the internet would be slow. Option D is wrong because S3 Transfer Acceleration is for accelerating transfers, but the slow link still limits speed.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
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.
Related concept
Static NAT maps one inside address to one outside address.
Provision a 1 Gbps AWS Direct Connect connection.
Why it's wrong here
High cost and over-provisioned for one-time transfer.
Common exam traps
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
What to study next
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related SAP-C02 NAT questions on configuration and troubleshooting.
