Not sure which category to post or if this is a good place for this at all BUT,

I am looking for question databases for A+, Net+, Linux+ and Server+ for my Moodle server. I teach HS and Adult alike. I have several questions that I have put on but not enough. It is a practice for general purposes and practice for the certifications. It is also a good way to keep from having to lecture all the time.
Love to have it in the format of question: right answer(s) and then wrong so I can copy and paste in but really, any help would be really apprec.

I am concerned about copywrite.
