220-1102 Operating Systems Practice Question

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✗

  Boot from Windows installation media and run 'chkdsk /f' on the C: drive

  Why it's wrong here

  Running chkdsk /f from installation media scans for and repairs NTFS file system corruption, such as bad sectors or metadata errors. However, the automatic repair loop is typically triggered by a failed Windows Update, corrupted boot-critical files, or incompatible drivers, none of which are filesystem issues that chkdsk can correct. Even if the volume is clean, Windows will continue to fail during normal boot because the repair loop is initiated by the Boot Configuration Data or recovery environment, not by disk integrity.

• ✓

  From the Advanced Options, go to Troubleshoot > Advanced Options > Startup Settings > Restart > select Safe Mode

  Why this is correct

  Booting into Safe Mode from the Advanced Options loads only the essential drivers and services, bypassing most startup programs and kernel-mode components. This often allows Windows to start successfully despite a failing update or problematic driver, after which you can uninstall the offending update, disable the service, or run System Restore. Because Safe Mode is non-destructive and preserves all user data, it is the appropriate first step to break the repair loop and diagnose the root cause.

• ✗

  Select 'Disable automatic restart on system failure' from the Advanced Options and then restart normally

  Why it's wrong here

  The 'Disable automatic restart on system failure' setting alters how Windows responds to a bugcheck (BSOD) by preventing an immediate reboot, allowing you to read the stop code. In an automatic repair loop, the system does not necessarily crash with a BSOD; instead, the boot manager repeatedly detects a failed startup and restarts into the recovery environment. Even with automatic restart disabled, you'll still see the recovery/repair screen each cycle, so the loop continues and the actual startup failure remains unaddressed.

• ✗

  Reinstall Windows 10 using the 'Reset this PC' option from the recovery environment

  Why it's wrong here

  The 'Reset this PC' option reinstalls Windows and, depending on whether you choose 'Keep my files' or 'Remove everything', can preserve only personal files or wipe the entire drive, but it always removes installed applications and changes system settings. This is a highly destructive, time-consuming procedure that should be reserved for cases where no other recovery method works. In this scenario, Safe Mode offers a faster, non-destructive path to resolve the update problem, so Reset is not the correct first-line action.
