Module Graded Quiz (Linux Fundamentals) Answers 2025

Question 1

What is an advantage of RHEL?

  • ✅ The versions of software are controlled so only patches are added

  • ❌ Everything is free

🔹 Explanation:
RHEL (Red Hat Enterprise Linux) provides stability and reliability by using well-tested, controlled versions of software and only adding security patches or bug fixes—not constant new features.

Question 2

Why does Fedora have so many releases?

  • ✅ It is designed to test new innovative features

  • ❌ It is designed to get new version so software is more stable

🔹 Explanation:
Fedora is a community-driven, cutting-edge distribution used to test and develop new features that may later appear in RHEL.

Question 3

Can you use Ubuntu on Internet of Things (IoT)?

  • ✅ Yes

  • ❌ No

🔹 Explanation:
Ubuntu Core is a lightweight version of Ubuntu specifically designed for IoT devices, so Ubuntu can indeed be used for IoT applications.

Question 4

Why does Linux not have a GUI?

  • ✅ It has a GUI

  • ❌ It is too hard to code

🔹 Explanation:
Linux does have a GUI, such as GNOME, KDE, XFCE, and others — it’s just that the GUI is optional, as Linux can also run purely from the command line for flexibility.

Question 5

Which command allows you to change the current directory?

  • ❌ cat

  • ✅ cd

  • ❌ ls

  • ❌ cp

🔹 Explanation:
The cd (change directory) command is used in Linux to move between directories within the file system.

Question 6

Which command deletes a file?

  • ❌ delete

  • ❌ del

  • ✅ rm

🔹 Explanation:
The rm command (remove) is used to delete files in Linux. For example, rm file.txt permanently removes that file.

Question 7

Where was UNIX invented?

  • ✅ Bell Labs

  • ❌ Microsoft Labs

  • ❌ Google

🔹 Explanation:
UNIX was created in the 1960s at Bell Labs by Ken Thompson and Dennis Ritchie — it later inspired Linux and other operating systems.

Question 8

Which license does Linux use?

  • ✅ GPL

  • ❌ BSD

  • ❌ Mozilla

  • ❌ Proprietary

🔹 Explanation:
Linux uses the GNU General Public License (GPL), which allows anyone to freely use, modify, and distribute the software — as long as they share their changes under the same license.

Question 9

If you modify Linux source code you cannot charge anyone for that change.

  • ✅ False

  • ❌ True

🔹 Explanation:
Under the GPL, you can charge for distributing or supporting Linux modifications — but you must still make the source code available under the same license.

Question 10

You need to be a Linux partner to change the source code.

  • ✅ False

  • ❌ True

🔹 Explanation:
Linux is open-source, meaning anyone can modify its source code without needing to be an official partner or organization.

🧩 Summary:

  • RHEL focuses on stability, while Fedora tests innovation.

  • Ubuntu supports IoT via Ubuntu Core.

  • Linux does have GUIs (like GNOME, KDE).

  • Key commands: cd to change directories, rm to delete files.

  • UNIX was invented at Bell Labs.

  • Linux uses the GPL license, allowing open modification and redistribution.

  • Anyone can modify Linux code and even charge for their version — as long as they follow GPL rules.

✅ Key takeaway:
Linux’s strength lies in its open-source nature, flexibility, and collaboration — enabling innovation from community testing (Fedora) to enterprise stability (RHEL).
