Are these real exam questions?

What do the paid DEA-C01 practice sets add?

How do I know if I'm ready for DEA-C01?
- Take the timed practice exam and look at your score by domain: the weakest domains show where to study next. ExamPark's readiness estimate uses your recent timed exams. It is our own estimate, not an official AWS score, and no practice exam can promise a pass.
