A Plus Certification Quizzes & Trivia

EnShort A+ progress test exam covering study guide chapters 1 & 2 (Domain 1). Please note that this is not a 'brain dump' or any such thing. I have written these questions based on the Sybex study guide for the A+ exam, and so a good mark here is not any kind of formal prep for the exam although I would trust it to adequatly test for a level of preparednessand show a sufficient level of revision effort and learning. The pass mark (60%) is also entirely arbitrary but one I would say gives at least good odds that, if achieved in all Domains, could be converted to a real exam pass with a little extra effort. [NB: Editied Q18 to eliminate ambiguity]
