What are the major impacts of not understanding software distribution licenses while developing software?

A.

Financial Implications
B.

Credibility
C.

Resources
D.

All of the above

Correct Answer
D. All of the above

Explanation
Not understanding software distribution licenses while developing software can have major impacts in terms of financial implications, credibility, and resources. Financially, it can lead to potential legal issues and costly penalties for non-compliance with licensing agreements. In terms of credibility, not understanding licenses can damage the reputation of the software developer and their ability to attract clients or users. Additionally, not understanding licenses can result in wasted resources, such as time and effort spent on developing software that cannot be legally distributed or used. Therefore, all of the above impacts can occur if software distribution licenses are not understood.

Which below is not a classification of open source licenses?

A.

Protective
B.

Permissive
C.

Freeware

Correct Answer
C. Freeware

Explanation
Freeware is not a classification of open source licenses because freeware refers to software that is available for use at no cost but does not necessarily provide the freedom to modify or distribute the source code. Open source licenses, on the other hand, allow users to access, modify, and distribute the source code of the software. The classifications of open source licenses are protective, which include copyleft licenses that require derivative works to be released under the same license, and permissive licenses that have fewer restrictions on how the software can be used and distributed.

You cannot use open-source software under a protective license (Like GPL) for commercial purposes.

A.

Correct. GPL is allowed only for non commercial purposes
B.

Incorrect. GPL can be used for commercial purposes as long as you dont distribute it under your software package, or you distribute your software package under GPL

Correct Answer
B. Incorrect. GPL can be used for commercial purposes as long as you dont distribute it under your software package, or you distribute your software package under GPL

Explanation
The correct answer is incorrect because it states that GPL can be used for commercial purposes as long as you don't distribute it under your software package or distribute your software package under GPL. However, this is not true. GPL, or General Public License, is a protective license that requires any derivative works or software packages that include GPL-licensed code to also be distributed under GPL. This means that if you use GPL-licensed software in your commercial project, you must also distribute your project under GPL, which may not align with your commercial goals.

You can embed an open-source library under a permissive license (Like BSD) into a commercial software product and distribute it without the end-user knowing about it.

A.

True
B.

False. You have to attribute the usage of open source software to its original author

Correct Answer
B. False. You have to attribute the usage of open source software to its original author

Explanation
The explanation for the given correct answer is that when using an open-source library under a permissive license like BSD in a commercial software product, it is not sufficient to distribute it without the end-user knowing about it. The open-source license typically requires attribution to the original author or contributors of the library. Therefore, it is necessary to give credit to the original author when using open-source software in a commercial product.

Which one of the below licenses is an Open Source license but not a protective license?

A.

GNU LGPL
B.

BSD
C.

MPL

Correct Answer
B. BSD

Explanation
The BSD license is an Open Source license but not a protective license. This means that it allows for the free use, modification, and distribution of the software without imposing many restrictions on the users. Unlike protective licenses such as GNU LGPL, the BSD license does not require derivative works to be licensed under the same terms, allowing for greater flexibility in how the software is used and integrated into other projects.

What is a weakly protective open source license?

A.

You can distribute it inside a commercial software product as long as you attribute it.
B.

You can distribute it inside a commercial software product as long as you attribute it and distribute the source code of the changes you made to the protective part of it
C.

You can only distribute it inside an open source software product

Correct Answer
B. You can distribute it inside a commercial software product as long as you attribute it and distribute the source code of the changes you made to the protective part of it

Explanation
A weakly protective open source license allows the distribution of the open source software within a commercial software product, but with the condition that the software is attributed and the source code of any modifications made to the protective part of the software is also distributed. This means that while the software can be used in a commercial product, the modifications made to the protective part must be made available to others as well.

Is it possible to use GPL Licensed library for a software product developed in Soliton?

A.

No
B.

Yes, though I will have to consult the License Review Board to ensure that I can use it for the way I use it.

Correct Answer
B. Yes, though I will have to consult the License Review Board to ensure that I can use it for the way I use it.

Explanation
The correct answer is "Yes, though I will have to consult the License Review Board to ensure that I can use it for the way I use it." This answer suggests that it is possible to use a GPL Licensed library for a software product developed in Soliton, but it is important to consult the License Review Board to ensure that the usage complies with the licensing terms and conditions.

Which organization manages the most used free license for content?

A.

Free Software Foundation
B.

World Wide Web Consortium (W3C)
C.

Creative Commons

Correct Answer
C. Creative Commons

Explanation
Creative Commons is the correct answer because it is the organization that manages the most used free license for content. Creative Commons provides a range of copyright licenses that allow creators to choose the permissions they want to grant to others regarding their work. These licenses have become widely adopted and are used by individuals, organizations, and institutions to share and distribute content freely while still retaining certain rights.

I need a blip sound for one of my button clicks. Is it okay if I search in Google for a small wav file, download it and embed it into my software product?

A.

Yes
B.

No, Audio (music or not) should also be treated as content

Correct Answer
B. No, Audio (music or not) should also be treated as content

Explanation
Embedding audio files, whether they are music or not, into a software product should be treated as content. This means that proper permissions and licensing should be obtained to use the audio file, just like any other type of content. Simply searching and downloading a small WAV file from Google may not ensure that you have the necessary rights to use that audio file in your software product.

I need a regular expression to validate a string to be an email id. Is it okay if I search in Google, find a StackOverflow answer, and copy-paste that regular expression into my code?

A.

Yes
B.

No, Stack overflow should be used only for learning and understanding

Correct Answer
B. No, Stack overflow should be used only for learning and understanding

Explanation
The correct answer is No because while Stack Overflow can be a helpful resource for learning and understanding concepts, it is not advisable to directly copy and paste code from it without fully understanding it. It is important to review and modify the code to fit the specific requirements and context of your project. Additionally, blindly copying code can lead to potential security vulnerabilities or compatibility issues. It is always recommended to have a good understanding of the code you are implementing.
