- A
Use S3 Transfer Acceleration to speed up the transfer
Why wrong: Transfer Acceleration optimizes internet path but is still limited by the 100 Mbps bandwidth.
- B
Use S3 Multipart Upload to upload files in parallel
Why wrong: Multipart Upload is for large files but still limited by bandwidth; cannot achieve 10 TB in 5 days over 100 Mbps.
- C
Use AWS Snowball Edge device to ship the data
Snowball Edge is ideal for large data volumes over slow networks; physical shipping is faster.
- D
Use AWS DataSync over the existing internet connection
Why wrong: DataSync can transfer data over the internet, but at 100 Mbps, it would take more than 5 days.
- E
Use AWS Direct Connect to establish a dedicated network connection
Why wrong: Direct Connect requires setup and may not be provisioned in time; also bandwidth can be increased but cost may be high.
MLS-C01 Data Engineering Practice Question
This MLS-C01 practice question tests your understanding of data engineering. 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 needs to transfer 10 TB of data from an on-premises data center to Amazon S3. The network bandwidth is limited to 100 Mbps, and the transfer must complete within 5 days. Which TWO options are viable? (Choose TWO.)
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 to ship the data
AWS Snowball Edge is a physical device for large data transfers over slow networks. AWS DataSync can be used if there is some bandwidth, but with 100 Mbps, it would take ~10 days, exceeding the 5-day window. Option B (S3 Transfer Acceleration) uses existing internet, which is still limited. Option C (Direct Connect) would require setup time and may not meet the window. Option E (S3 Multipart Upload) is for uploading files, not for bulk transfer over slow link.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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.
