- A
The user’s Time Machine backup has failed
Why wrong: Time Machine failure does not prevent booting; it only affects backups.
- B
The firmware password is enabled
Why wrong: A firmware password shows a lock icon, not a folder with a question mark.
- C
macOS cannot locate a valid boot volume or system folder
This is the classic symptom of a missing or corrupted boot volume, often fixable via Recovery Mode or Disk Utility.
- D
The user’s login keychain is corrupted
Why wrong: A corrupted keychain prevents login but does not stop the system from booting.
Question 93 of 750
Folder with Question Mark on macOS Startup for CompTIA A+ Core 2
This 220-1202 practice question tests your understanding of macos features and tools. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. 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 graphic designer reports that their MacBook Pro running macOS Monterey suddenly shows a gray screen with a folder icon containing a question mark at startup. They have important client files on the internal SSD. What is the most likely cause of this issue?

Clue:
"most likely"Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Quick Answer
The answer is that macOS cannot locate a valid boot volume or system folder, which is the most likely cause of the gray screen with a folder question mark on macOS startup. This occurs because the Mac’s firmware, during the boot process, searches for a bootable system folder on the internal SSD but fails to find one, often due to a corrupted boot loader, a damaged directory structure, or a disconnected internal drive. For the CompTIA A+ Core 2 220-1202 exam, this scenario tests your understanding of macOS startup troubleshooting and common boot failure indicators, with a common trap being to confuse this symptom with a failed backup or login issue—remember, the folder icon points to the boot volume, not user data. A helpful memory tip is to think of the question mark as the system asking, “Where is my boot volume?” which directly points to a missing or unreadable system folder.

Correct answer & explanation
✓
macOS cannot locate a valid boot volume or system folder
The gray screen with a folder icon containing a question mark indicates that the Mac's startup process cannot locate a valid boot volume or system folder. This is a classic symptom of a missing or corrupted boot loader, damaged system files, or a disconnected internal SSD, which prevents macOS from finding the required bootable system.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The user’s Time Machine backup has failed
Why it's wrong here
Time Machine failure does not prevent booting; it only affects backups.
- ✗
The firmware password is enabled
Why it's wrong here
A firmware password shows a lock icon, not a folder with a question mark.
- ✓
macOS cannot locate a valid boot volume or system folder
Why this is correct
This is the classic symptom of a missing or corrupted boot volume, often fixable via Recovery Mode or Disk Utility.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
The user’s login keychain is corrupted
Why it's wrong here
A corrupted keychain prevents login but does not stop the system from booting.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The A+ exam often tests the distinction between boot-level failures (folder icon) and post-boot authentication issues (keychain), so candidates mistakenly choose a corrupted login keychain because they associate question marks with 'missing' items without understanding the boot sequence.
Trap categories for this question
Command / output trap
A firmware password shows a lock icon, not a folder with a question mark.
Detailed technical explanation
How to think about this question
The folder-with-question-mark icon appears when the Mac's EFI firmware cannot locate a valid boot.efi file or a properly formatted HFS+/APFS container with a macOS system. This can be caused by a failed firmware update, a damaged System Integrity Protection (SIP) configuration, or a hardware failure of the internal SSD's controller. In real-world scenarios, reseating the SSD or booting to Internet Recovery (Command-Option-R) and running Disk Utility's First Aid often resolves the issue if the drive is still functional.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
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
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 220-1202 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
