Just passed the AZ-400 exam, and one thing stood out immediately: this test is about decision-making, not memorizing definitions. The questions are built around real DevOps scenarios, so you need to understand the context behind each solution, not just the theory.
ITExamsTopics.com was one of the most useful resources I used. The practice questions are scenario-driven and very similar to the actual exam style, which helped me think through problems the way the exam expects. Happy to answer questions for anyone preparing for AZ-400.
