What is cloud storage synchronization and a potential pitfall?

• A. Speed improvement when online
• B. Automatic backups without conflicts
• C. Storing files on local disks only
• D. Keeping files synced across devices; pitfall: conflicts when edits occur offline

Answer: (D)

Cloud storage synchronization means your files live in the cloud and are automatically copied to all devices linked to your account so you can access the same up-to-date versions from anywhere. The key idea is that edits on one device propagate to the others, keeping everything in sync.

A common pitfall is editing files while offline on more than one device. When you reconnect, the service has to merge those different changes. If the edits conflict, you may end up with multiple versions or duplicates, or you’ll need to manually resolve which version to keep. This is a real-world reminder that syncing aims to keep things identical across devices, but conflicts can arise when changes happen without online visibility.

The other options miss this behavior: one describes speed online rather than synchronization, another assumes automatic backups without any conflicts—which isn’t guaranteed—and another suggests storing files only on local disks, which contradicts cloud syncing.
