CompTIA IT Fundamentals (FC0-U51) — Question 17

A user has downloaded an application file with the .dmg file extension. Which of the following operating systems can be used with this file by default?

Answer options

• A. iOS
• B. Windows
• C. Mac OS
• D. Chrome OS

Correct answer: C

Explanation

The correct answer is Mac OS, as .dmg files are disk image files specifically designed for macOS. iOS, Windows, and Chrome OS do not natively support .dmg files and would require additional software to access the contents.
