A company must move 80 TB to Azure but has only 50 Mbps of internet bandwidth. Which method fits?
A.AzCopy over the internet
AzCopy is online — bandwidth-bound, same problem.
B.Azure Import/Export — ship physical disks to a datacenter
Disk shipping bypasses bandwidth entirely. Correct.
C.Azure File Sync upload
File Sync is an online sync service, not bulk migration.
D.Storage Explorer drag-and-drop
Storage Explorer is a UI over online transfer.
Why this answer
The bandwidth math is the tell: 80 TB at 50 Mbps would take ~5 months. Offline transfer options exist exactly for this: Import/Export (ship your drives) or Data Box (Microsoft ships an appliance). Online tools can't escape physics.
