220-1102 Practice Question: A technician is troubleshooting a Windows 10…
This 220-1102 practice question tests your understanding of a technician is troubleshooting a windows 10…. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. A key principle to apply: bootrec is a tool used for repairing boot-related issues.. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A technician is troubleshooting a Windows 10 workstation that fails to boot, displaying the error 'Boot selection failed because a required device is inaccessible.' The technician suspects the Boot Configuration Data (BCD) is corrupted. The technician boots from a Windows 10 installation media and opens Command Prompt from the Repair options. Which command should the technician run to rebuild the BCD?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
bootrec /rebuildbcd
This command scans for Windows installations and allows rebuilding the BCD store, directly addressing BCD corruption.
B
Distractor review
bcdedit /export
This exports the current BCD to a file; it does not repair a corrupted BCD.
C
Distractor review
sfc /scannow
This checks for corrupted system files but does not repair boot configuration data.
D
Distractor review
chkdsk /f
This checks the file system for errors and fixes them, but does not address BCD corruption.
Answer analysis
Why the other options are wrong
Understanding why incorrect options are tempting is as important as knowing the correct answer.
- ✗
bcdedit /export
This exports the current BCD to a file; it does not repair a corrupted BCD.
- ✗
sfc /scannow
This checks for corrupted system files but does not repair boot configuration data.
- ✗
chkdsk /f
This checks the file system for errors and fixes them, but does not address BCD corruption.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Candidates might confuse `bootrec /rebuildbcd` with `bcdedit /export`, mistaking export for repair functionality.
Technical deep dive
How to think about this question
The 'Boot selection failed because a required device is inaccessible' error strongly indicates an issue with the Boot Configuration Data (BCD) store, which contains critical boot parameters for Windows. The `bootrec /rebuildbcd` command is specifically designed to address this problem. When executed from the Windows Recovery Environment (WinRE) Command Prompt, it scans all disks for compatible Windows installations. Upon finding them, it prompts the user to add the detected installations to the BCD store, effectively rebuilding a potentially corrupted or missing BCD from scratch. This process ensures that the system has valid entries to locate and load the operating system, directly resolving the 'inaccessible device' error related to boot selection. This command is distinct from the other options because it targets the boot configuration itself. `bcdedit /export` merely saves the current BCD state, which is unhelpful if the BCD is already corrupted. `sfc /scannow` focuses on verifying and repairing core Windows system files, not the boot configuration data that precedes the OS load. Similarly, `chkdsk /f` checks and repairs file system integrity on a volume, which might be a secondary issue but doesn't directly rebuild the BCD entries responsible for initiating the boot process. The scenario's error message precisely points to a BCD issue, making `bootrec /rebuildbcd` the most direct and effective solution.
KKey Concepts to Remember
- bootrec is a tool used for repairing boot-related issues.
- /rebuildbcd specifically scans for Windows installations and rebuilds the BCD.
- The BCD stores boot options and parameters for Windows.
- This command is typically run from the Windows Recovery Environment (WinRE).
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
bootrec is a tool used for repairing boot-related issues.
