AWS Snowball is a physical device for offline data transfer. For large datasets with limited bandwidth, Snowball can transfer data faster by shipping the device, bypassing network constraints.
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 DataSync
Why it's wrong here
DataSync is online and still limited by network bandwidth.
- ✓
AWS Snowball
Why this is correct
Correct. Snowball accelerates transfer by shipping storage devices, bypassing network limitations.
- ✗
S3 Transfer Acceleration
Why it's wrong here
Transfer Acceleration speeds up uploads but still relies on the network; at 100 Mbps, it would still take a long time for 200 TB.
- ✗
AWS Direct Connect
Why it's wrong here
Direct Connect provides dedicated network connection but does not accelerate beyond bandwidth limits.
