220-1102 Question 204
Single answerBackupsA small accounting office stores client spreadsheets on a Windows 11 workstation. The user accidentally overwrote a workbook with incorrect data this morning and did not notice until the afternoon. The PC is configured with File History to back up the Documents library to an external drive every hour, and the drive is currently connected. The user needs the fastest way to recover yesterday's correct version of only that workbook without affecting any other files. What should the technician do?
- A
Open File History and restore the previous version of the workbook from the Documents library
- B
Run System Restore to roll the workstation back to yesterday's restore point
- C
Reinstall Microsoft Excel and then open the AutoRecover folder
- D
Use Disk Cleanup to remove temporary files and recover the workbook from free space
Show answer and explanation
Correct answer: A
Explanation
The best answer is to restore the previous version of the workbook using File History. In Windows, File History is a user-data backup feature intended for versioned recovery of files in libraries and other configured folders. This makes it ideal when a user needs a prior copy of one file after accidental overwrite or deletion. By contrast, System Restore targets operating system configuration, not routine recovery of user documents. Reinstalling an application does not restore document versions, and cleanup tools are unrelated to backup recovery. This aligns with Microsoft guidance that File History is used to restore personal files or earlier versions, while System Restore is used to recover system settings and protected system files.
- A. Correct.
Correct. File History is designed to restore earlier versions of user files in protected locations such as Documents, Desktop, Pictures, and other selected folders. Because the issue is a single overwritten workbook and hourly backups exist, restoring the prior version of that specific file is the fastest and least disruptive method.
- B. Incorrect.
Incorrect. System Restore is intended to revert system files, drivers, installed applications, and registry settings. It does not function as a primary tool for recovering a previous version of a user document such as an Excel workbook. Using it would also introduce unnecessary risk by changing system state.
- C. Incorrect.
Incorrect. Reinstalling Excel would not restore the previous contents of an overwritten workbook. AutoRecover can help with unsaved or unexpectedly closed files in some situations, but it is not a reliable backup method for a file that was saved with bad data and later needs a prior version from yesterday.
- D. Incorrect.
Incorrect. Disk Cleanup removes unneeded files to free storage space; it does not recover prior versions of user documents. Attempting recovery from free space is not an appropriate first step when a valid File History backup already exists.
