FC0-U71 Applications and Software Practice Question
A user wants to install a software package on a Linux system using a package that ends in .deb. Which Linux distribution family is most likely being used?
⚠ Common exam trap
FC0-U71 often tests the mapping between package extensions and distro families — candidates confuse .deb (Debian/Ubuntu) with .rpm (RHEL/SUSE) or forget that Arch uses pacman with its own 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
✓
Debian-based (e.g., Ubuntu)
The .deb package format is native to Debian and its derivatives, including Ubuntu, Linux Mint, and Kali Linux. These distributions use the dpkg low-level package manager and APT (Advanced Package Tool) as the high-level front end for dependency resolution and repository management. Installing a .deb file is typically done with 'dpkg -i' or 'apt install ./package.deb'.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
openSUSE
Why it's wrong here
openSUSE uses the RPM package format managed by Zypper, so a .deb file cannot be installed natively. The .deb format is tempting because it is widely encountered on Debian-derived systems, where dpkg and APT handle it correctly; openSUSE would instead require conversion or an RPM build.
- ✗
Arch Linux
Why it's wrong here
Arch Linux uses pacman with .pkg.tar.zst packages, not the Debian .deb format, so it cannot install this package natively. It is tempting because Arch is a well-known Linux distribution family, and would be correct if the package ended in .pkg.tar.zst or the user built from the AUR.
- ✓
Debian-based (e.g., Ubuntu)
Why this is correct
The .deb extension is the native package format for Debian-based distributions, including Ubuntu, which use dpkg and APT for installation. This directly satisfies the stem's constraint of a package ending in .deb, unlike RPM-based families such as Red Hat or SUSE, which cannot natively install .deb files.
- ✗
Red Hat Enterprise Linux
Why it's wrong here
Red Hat Enterprise Linux uses RPM packages managed by DNF or YUM, so .deb files are not natively installable. The .deb extension is tempting because Debian and Ubuntu dominate desktop Linux, but RHEL's package management expects RPM; installing .deb there needs alien or a rebuild.
