CV0-004 Deployment Practice Question
A company must migrate 50 TB of data from an on-premises NFS server to Amazon S3 within one week. The network bandwidth averages 50 Mbps. The administrator is evaluating AWS DataSync and AWS Snowball. Which service should the administrator choose?
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
At 50 Mbps, transferring 50 TB would take about 95 days, exceeding the one-week deadline. Snowball provides offline physical transfer, making it feasible within a week.
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 this is correct
Snowball is an offline physical device that can handle large datasets quickly.
- ✗
AWS DataSync
Why it's wrong here
DataSync is network-based and would be too slow given bandwidth and data size.
- ✗
S3 Transfer Acceleration
Why it's wrong here
Acceleration improves speed but still network-dependent; insufficient for 50 TB in a week over 50 Mbps.
- ✗
AWS Database Migration Service
Why it's wrong here
DMS is for database migration, not file storage.
