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.

Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
AWS Snowball
Why it's wrong here
Snowball is an offline device, not over the internet.
- ✓
AWS DataSync
Why this is correct
DataSync accelerates online transfers with parallel operations.

Why it's wrong here
S3TA uses edge locations but may not achieve the required speed for 200 TB in 5 days at 1 Gbps (max ~54 TB).
- ✗
AWS Direct Connect
Why it's wrong here
Direct Connect is a dedicated network connection, not a data transfer service.
