Which feature creates snapshots of computer files?

• A. Shadow Copies
• B. Update Frequency
• C. Alerts
• D. Server Settings

Answer: (A)

Snapshots of computer files are created by a feature built to preserve point-in-time versions of files so you can restore them later. Shadow Copies does exactly that by capturing the state of files and folders at specific moments, even while they’re in use, so you can recover earlier versions if something gets corrupted, deleted, or affected by malware. Update frequency, alerts, and server settings don’t create or store file versions—they relate to how updates are handled, how notifications are sent, and how the system is configured. So the feature that creates file snapshots is Shadow Copies.
