There are no sources that give the answers to the actual questions on the EPA 608 certification exam. To do so would be immoral and possibly illegal. Your best bet is to obtain a study guide, which is found for free on many websites.

The NVAC EPA test would be almost impossible to cheat on, but you can study for it and learn what you need to know to pass it. There are resources and sites online to help you prepare for the test.
Passing the EPA section 608 certification exam depends on whether you are taking the "open book" version (which is what most, if not all, online websites offer) or a proctored version (a class given in an actual classroom). Each section of the exam (Core, Type I, Type II, and Type III) has 25 questions. Everyone that takes the exam is required to take the Core plus at least one other section (Type I, Type II, or Type III). If you take, and pass, the Core plus all of the three remaining sections, you will receive Universal certification. For an "open book" exam, you must answer correctly 21 of 25 (84%) questions per section in order to pass that section. For a proctored exam, you must answer correctly 18 of 25 (72%) questions per section in order to pass that section.
