About the AZ-400 practice exams

These 14 practice exams prepare you for the Azure DevOps Engineer Expert (AZ-400) certification. Each one is a full-length, timed mock test of 55 questions in 100 minutes, so the set gives you 770 questions in all, and no question repeats from one exam to the next. Questions are drawn to match the weight of each AZ-400 exam domain, so the Design and implement build and release pipelines domain (52.7%) gets the most questions, as it does on the real exam.
