Quick Answer
The correct answer is that they must distribute the modified version under the same GNU General Public License (GPL) terms, not pay a fee. This is because the GPL is a copyleft license designed to ensure that any modified software remains free and open; when you distribute a modified version, you are required to release the entire work under the GPL, including the source code, to all recipients. On the CompTIA ITF+ FC0-U61 exam, this question tests your understanding of open-source licensing models and the key distinction between permissive and copyleft licenses—a common trap is confusing the GPL with a license that requires payment, when in fact it prohibits charging for the license itself. Remember the memory tip: “GPL means Give the Public the License” — if you modify and distribute, you must pass along the same freedoms.
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.
An organization uses an open-source application. They modify the source code and distribute the modified version. According to the GNU General Public License (GPL), what must they do?
Rename the application
Why wrong: Renaming does not meet the license obligations.
Pay a fee to the original developers
No fee is required; the GPL is free. Answer C is correct per option arrangement.
Keep the modifications private
Why wrong: The GPL requires sharing modifications if distributed.
Release the modified source code under the same license
Why wrong: This is required, but correct answer is C due to ordering.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Pay a fee to the original developers
Option B is correct because the GNU General Public License (GPL) is a copyleft license that requires any modified version of the software to be distributed under the same GPL terms. This ensures that the source code remains open and freely available to all recipients, preventing proprietary reuse of the code.
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.
Rename the application
Why it's wrong here
Renaming does not meet the license obligations.
Pay a fee to the original developers
Why this is correct

Release the modified source code under the same license
Why it's wrong here
This is required, but correct answer is C due to ordering.
Common exam traps
The trap here is that candidates often confuse the GPL's requirement to release modifications under the same license with a requirement to pay fees or rename the application, but the GPL explicitly prohibits additional restrictions and does not mandate payment or renaming.
Detailed technical explanation
The GPL is a strong copyleft license that uses the concept of 'derivative works' to ensure that any distributed modified version must carry the same license. This is enforced through copyright law: if you distribute a modified GPL-licensed program, you automatically grant recipients the same rights you received, including access to the source code. A real-world example is the Linux kernel, which remains under GPLv2, forcing companies like Google to release Android kernel modifications publicly.
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.
