CompTIA A+ Core 2 (220-1102) — Question 391

A user is unable to start a computer following a failed Windows 10 update. When trying to start the computer, the user sees a blue screen of death. Which of the following steps should a technician take to diagnose the issue?

Answer options

• A. Perform a safe mode boot.
• B. Run the System Restore wizard.
• C. Start the computer in the last known-good configuration.
• D. Reset the BIOS settings.

Correct answer: A

Explanation

Performing a safe mode boot allows the technician to start the computer with minimal drivers and can help identify the cause of the issue. The other options, while potentially helpful in different contexts, do not provide the immediate diagnostic capability that safe mode offers for a blue screen error following an update.
