- A
Amazon S3 multipart upload
Why wrong: Multipart upload helps with large files but does not accelerate overall transfer speed.
- B
AWS Direct Connect
Why wrong: Direct Connect is a dedicated network, but may not be feasible quickly.
- C
AWS DataSync
Why wrong: DataSync uses the network, not ideal for slow connections.
- D
AWS Snowball
Snowball physically ships data, bypassing the slow internet.
- E

CV0-004 Deployment Practice Question
This CV0-004 practice question tests your understanding of deployment. 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 an on-premises file server to Amazon S3. The migration must be completed within two weeks and the internet connection is slow. Which TWO AWS services can accelerate the transfer?
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
✓
AWS Snowball
AWS Snowball (Option D) is a petabyte-scale data transport solution that uses secure physical devices to transfer large amounts of data to AWS, bypassing the internet entirely. For a 50 TB migration over a slow connection within a two-week window, Snowball is ideal because it avoids network bandwidth constraints and can transfer data at the speed of shipping, not the internet.
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
The trap here is that candidates may confuse S3 Transfer Acceleration (Option E) as a solution for all slow connections, but it only optimizes internet routing and does not overcome severe bandwidth limitations for multi-terabyte transfers within a strict deadline.
Detailed technical explanation
How to think about this question
AWS Snowball uses a ruggedized device with built-in storage and compute capabilities, supporting encryption at rest with AWS KMS and tamper-resistant hardware. The device is shipped to the customer, data is copied locally via the Snowball client (which uses a 10GbE interface), and then shipped back to AWS for ingestion into S3. This physical transport method effectively bypasses network latency and bandwidth limitations, making it ideal for large-scale migrations where time and slow connectivity are constraints.
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.
TExam Day Tips
- 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 practitioner preparing for the CV0-004 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
