Quick Answer
The answer is the MIT License and the GNU General Public License (GPL). Both are examples of open source licenses because they grant users the legal right to run, study, modify, and distribute software freely, though they differ in how they handle derivative works. The GPL is a copyleft license that requires any modified version of the software to also be released under the same GPL terms, ensuring the code remains open and free for all users. On the CompTIA ITF+ FC0-U61 exam, this topic tests your understanding of software licensing models, often appearing in multiple-choice questions that ask you to distinguish open source from proprietary or public domain licenses. A common trap is confusing the GPL with permissive licenses like MIT, which allow proprietary reuse without requiring source code disclosure. To remember the difference, think of GPL as “give back” (copyleft) and MIT as “minimal restrictions” (permissive).
This FC0-U61 practice question tests your understanding of applications and software. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
Which TWO of the following are examples of open-source software licenses?
Apple App Store License
Why wrong: Apple App Store License is proprietary.
GNU GPL
The GNU General Public License is a widely used open-source license.
MIT License
The MIT License is a permissive open-source license.
Microsoft EULA
Why wrong: Microsoft EULA is a proprietary license.
Adobe EULA
Why wrong: Adobe EULA is proprietary.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
GNU GPL
The GNU General Public License (GPL) is a widely used open-source license that grants users the freedom to run, study, share, and modify the software. It requires that any distributed derivative work be licensed under the same GPL terms, ensuring the software remains free and open.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.

Common exam traps
The trap here is that candidates may confuse proprietary licenses (like EULAs) with open-source licenses, or think that any license that allows free download is open-source, ignoring the specific grant of modification and redistribution rights.
Detailed technical explanation
The GNU GPL is a copyleft license, meaning that any code derived from GPL-licensed code must also be distributed under the GPL, which prevents proprietary forks. The MIT License is a permissive open-source license that allows reuse with minimal restrictions, only requiring preservation of the copyright notice. Both are approved by the Open Source Initiative (OSI) and are commonly used in projects like the Linux kernel (GPL) and Node.js packages (MIT).
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the FC0-U61 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.
