Welcome to Wikipedia. Although everyone is welcome to contribute constructively to the encyclopedia, one or more of the external links you added such as to the page Project Management Professional do not comply with our guidelines for external links and have been removed. Wikipedia is not a collection of links; nor should it be used for advertising or promotion, and doing so is contrary to the goals of this project. Since Wikipedia uses nofollow tags, external links do not alter search engine rankings. If you feel the link should be added to the article, please discuss it on the article's talk page before reinserting it.

Sorry.
I added further links to providers I am not related with in order to make sure that the link to my page with the free sample questions is not regarded as advertisment. Obviously, the impression you got was the direct opposite of my intention.
I hope that my current solution (a footnote with a reference from the text body) is acceptable to you. People interested in the exam need some examples that help them understanding how the exam is built and what it requires from them.
My prep questions are free and do not require registration or anything else. Everyone may simply use them. I got feedback from self-learning groups, Universities and commercial training providers that they are using these questions for their education.
I feel very near to the Wikipedia vision with this approach.
PS: I spent many hours on the page. I hope that it is no more to be regarded as stub and sufficiently quotes references by now.
