- A
Disk Utility to restore the .app file to the SSD.
Why wrong: Disk Utility can erase and format drives, but it cannot create a bootable installer from an application file. It is not designed for this task.
- B
System Information to verify the SSD is bootable.
Why wrong: System Information only displays hardware and software information; it cannot create or modify bootable media.
- C
Terminal with the 'createinstallmedia' command.
This is the correct built-in tool. The command syntax is 'sudo /Applications/Install macOS Sonoma.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume'. It creates a bootable installer.
- D
Migration Assistant to copy the app to the SSD.
Why wrong: Migration Assistant transfers user data, applications, and settings from one Mac to another. It cannot create bootable installer media.
Quick Answer
The answer is Terminal with the createinstallmedia command. This built-in macOS utility is the official Apple method for creating a bootable macOS installer because it writes the installer application bundle to a target volume and automatically makes it bootable, which is essential for deploying macOS Sonoma across multiple iMacs. On the CompTIA A+ Core 2 220-1202 exam, this question tests your knowledge of macOS deployment tools and often appears as a trap where candidates mistakenly choose Disk Utility—which can only erase and format drives, not create installer media—or System Information, which lacks this capability entirely. To remember this, think of the command’s name: createinstallmedia literally means “create installer media,” and you run it in Terminal, not through a graphical interface. A helpful mnemonic is “Terminal Types the Tool,” reinforcing that the command line is the correct path for building bootable macOS installers.
220-1102 macOS Features and Tools Practice Question
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 needs to create a bootable macOS installer on an external SSD to deploy macOS Sonoma to multiple iMacs in the office. They have the 'Install macOS Sonoma.app' file. Which built-in macOS tool should they use to create the bootable drive?

Correct answer & explanation
Terminal with the 'createinstallmedia' command.
The 'createinstallmedia' command in Terminal is the official Apple tool for creating a bootable macOS installer from an application bundle. It writes the installer to the target volume and makes it bootable. Disk Utility can erase the drive but cannot create the installer media, and System Information does not have this capability.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.
