FC0-U71 Applications and Software Practice Question
A user wants to install a free text editor on their Windows computer. Which file extension is most likely used for the installer?
⚠ Common exam trap
FC0-U71 often tests OS-to-extension mapping — candidates may pick .dmg or .pkg because they sound like generic installers, but the exam expects recognition that .exe is the Windows-native installer format.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
.exe
On Windows, executable installers most commonly use the .exe extension (and .msi for Windows Installer packages). A free text editor for Windows would therefore be distributed as an .exe installer. The other extensions belong to different operating systems.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
.deb
Why it's wrong here
Debian packages install on Linux distributions via dpkg or apt, so Windows cannot execute them natively. It is tempting because .deb is a genuine installer format, and it would be the right answer if the target machine were running Debian or Ubuntu rather than Windows.
- ✓
.exe
Why this is correct
Windows installer packages are typically compiled executables, so a .exe file runs the setup routine directly. This satisfies the requirement of installing a free text editor on Windows, unlike .txt, .jpg or .csv, which are data formats Windows cannot execute.
- ✗
.dmg
Why it's wrong here
Disk image files mount on macOS to deliver applications, not Windows installers. It is tempting because .dmg is a legitimate packaged installer format, and it would be correct if the user were installing the text editor on an Apple Mac instead of a Windows PC.
- ✗
.pkg
Why it's wrong here
Package files are used by macOS Installer and some Unix systems, not Windows. It is tempting because .pkg is a real installer extension, and it would be the correct choice if the software were being deployed to macOS rather than to a Windows computer.
