The answer is to use AWS Snowball Edge devices. This is correct because transferring 50 TB to S3 over a 100 Mbps internet connection would take roughly 48 days, far exceeding the 30-day deadline, while Snowball Edge bypasses the slow internet bottleneck by physically shipping the data. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this scenario tests your understanding of when to choose offline data transfer over network-based options; a common trap is assuming S3 Transfer Acceleration or DataSync can solve bandwidth limitations, but both still rely on the same constrained internet pipe. Remember the key threshold: if your transfer time calculation exceeds your business timeline, Snowball is the answer. A useful memory tip is “Snowball for slow pipes, acceleration for long distances”—when bandwidth is the blocker, ship it.
SAP-C02 Practice Question: Accelerate Workload Migration and Modernization
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 migrating 50 TB of data from on-premises to Amazon S3 over a 100 Mbps internet connection. The migration must complete within 30 days. What should they do?
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
At 100 Mbps, transferring 50 TB would take approximately 48 days (50 TB * 1024 GB/TB * 1024 MB/GB * 8 bits/byte / (100 Mbps) / 86400 sec/day ≈ 48 days), exceeding the 30-day window. AWS Snowball Edge can transfer data faster via physical shipment. Option A (increase bandwidth) may not be feasible. Option C (S3 Transfer Acceleration) still uses internet. Option D (AWS DataSync) also uses network.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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 Snowball Edge devices
Why this is correct
Snowball Edge provides physical data transfer, overcoming bandwidth limitations.
Related concept
Read the scenario before looking for a memorised answer.
✗
Use AWS DataSync to transfer data
Why it's wrong here
DataSync still uses network and would be too slow given bandwidth constraints.
✗
Use AWS Direct Connect to increase bandwidth
Why it's wrong here
Direct Connect would require weeks to set up and still may not meet the timeline.
✗
Use S3 Transfer Acceleration
Why it's wrong here
Transfer Acceleration optimizes internet path but does not change bandwidth limit.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.

Variation 1. 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?
easy
A.Use AWS DataSync over the existing internet connection.
B.Enable S3 Transfer Acceleration on the destination bucket.
✓ C.Use AWS Snowball Edge devices to transfer the data.
D.Provision a 1 Gbps AWS Direct Connect connection.
Why C: 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.
