CompTIA A+ Core 1 (220-1001) — Question 145

After upgrading a smartphone's OS, Joe, a user, reports the smartphone no longer connects to his automobile automatically when near it. Joe restarts the smartphone, but the problem persists. Which of the following should a technician do NEXT to restore the previous functionality?

Answer options

• A. Connect the smartphone to the automobile via USB
• B. Reenable the smartphone's Bluetooth radio
• C. Perform a rollback of the smartphone's OS
• D. Enable airplane mode and then disable airplane mode

Correct answer: B

Explanation

The correct action is to reenable the smartphone's Bluetooth radio, as the OS upgrade may have disabled it. Connecting via USB does not address the Bluetooth connection issue, and rolling back the OS might not be necessary if Bluetooth can be restored. Enabling and disabling airplane mode is unlikely to resolve the Bluetooth connectivity problem.
