220-1101 Question 387
Single answerProprietary crash screensA technician is troubleshooting a user's MacBook that suddenly restarts and displays a multilingual message instructing the user to restart the computer. The issue occurs several times a day, often when an external Thunderbolt storage device is connected. Which of the following is the BEST interpretation of this crash screen and the most likely next troubleshooting focus?
- A
It is a macOS kernel panic, and the technician should focus on incompatible hardware, drivers, or low-level system extensions related to the Thunderbolt device.
- B
It is a Windows blue screen, and the technician should run SFC and DISM to repair system files.
- C
It is a Linux kernel warning, and the technician should rebuild the GRUB bootloader.
- D
It is an application crash notification, and the technician should reinstall the user's office productivity suite.
Show answer and explanation
Correct answer: A
Explanation
This question tests recognition of proprietary crash screens and the ability to apply that recognition in troubleshooting. In A+ Core 1, candidates should distinguish between platform-specific crash symptoms such as Windows BSODs and Apple kernel panic screens. A macOS kernel panic indicates a serious operating system or hardware-level fault rather than a normal application error. In real-world support, technicians should correlate the crash with recent changes or attached devices. Since the panic occurs when a Thunderbolt storage device is connected, best practice is to isolate that device, verify cables and ports, disconnect unnecessary peripherals, check for macOS updates, confirm device firmware and vendor compatibility, and review panic logs in macOS diagnostic reporting. Apple support documentation and standard troubleshooting practice both emphasize isolating peripherals and low-level software components when kernel panics recur.
- A. Correct.
Correct. On Apple systems, a proprietary crash screen with a message telling the user to restart in multiple languages is characteristic of a kernel panic. Kernel panics are caused by low-level failures, commonly involving hardware faults, peripheral conflicts, drivers, or kernel/system extensions. Because the problem appears when a Thunderbolt storage device is attached, the best next focus is that external hardware and its associated software components.
- B. Incorrect.
Incorrect. A Windows blue screen of death (BSOD) is a different proprietary crash screen and would not normally appear on a MacBook as a multilingual restart message. SFC and DISM are Windows repair tools used for system file integrity and image servicing, so they do not match the scenario.
- C. Incorrect.
Incorrect. Linux systems can experience kernel panics, but the described multilingual restart screen is strongly associated with macOS. Rebuilding GRUB addresses bootloader issues, not a recurring crash tied to an external Thunderbolt device after the OS has already loaded.
- D. Incorrect.
Incorrect. An application crash usually closes only the affected program and may generate an application error report. It does not typically force an immediate system restart message in multiple languages. Reinstalling an office suite would not address a system-level crash pattern linked to external hardware.
