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 Transfer Appliance
Transfer Appliance is a physical device for shipping large amounts of data when bandwidth is low. At 100 Mbps, 500 TB would take over 500 days; Transfer Appliance bypasses 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.
- ✓
Use Transfer Appliance
Why this is correct
Transfer Appliance is a physical device shipped to the data center, loaded, and returned — ideal for large, low-bandwidth migrations.
- ✗
Use gsutil rsync with parallel composite uploads
Why it's wrong here
gsutil also uses the network and would be similarly slow.
- ✗
Use Migrate for Compute Engine
Why it's wrong here
That service migrates VMs, not bulk data.
- ✗
Use Storage Transfer Service over the internet
Why it's wrong here
Storage Transfer Service uses the network, which would be too slow at 100 Mbps for 500 TB.
