They cover all 5 domains of the AZ-400 exam: Design and implement build and release pipelines (43%), Design and implement source control (18%), Configure processes and communications (13%), Develop a security and compliance plan (13%), Implement an instrumentation strategy (13%). Each section is weighted in the same proportion as the real exam, so nothing high-value is buried.
The AZ-400 exam has approximately 60 questions in 150 minutes, with a passing score of 700. Use the practice questions to confirm you are consistently above that line before booking the real exam.
Read a domain, then immediately answer practice questions on it — recall is what moves knowledge into long-term memory. Start with Design and implement build and release pipelines, and finish with a mixed set so you practise switching between topics.
They cover the content, but reading alone is not enough. Answer practice questions for every domain and take a timed practice exam; the notes are most useful when you return to them after a wrong answer.
