CompTIA Security+ Study Guide
CompTIA reserves the right to insert ungraded beta questions. As the name implies, CompTIA is “trying them out” to see how folks react. Most testers aren’t aware of these beta questions and it seems CompTIA puts them right at the beginning of the exam – which is a guaranteed panic-inducer.
If you see questions on the exam that cover topics that you’ve never seen, there’s a great chance they’re beta questions. Go ahead and try your best to guess an answer, but don’t let them upset you – they’re not graded.
