Which feature allows restoring previous versions of files by taking snapshots?

• A. Activity Log Export
• B. Shadow Copies
• C. Update Frequency
• D. Alerts

Answer: (B)

Shadow Copies provide point-in-time copies of files and folders, so you can restore previous versions when something goes wrong. This feature works by taking snapshots of the file system at specific moments, capturing the state of files as they existed then. With these snapshots, you can recover earlier versions of a file if you’ve edited it unintentionally, corrupted it, or been hit by ransomware, without needing a separate full backup fall-back. In practice, Windows users can use the Previous Versions option to access these shadow copies and restore the exact version they need. The other options don’t offer this versioning capability: exporting an activity log is about recording what happened, not preserving file states; update frequency concerns how often software is updated, not file versions; alerts are notifications, not mechanisms for restoring prior file states.
