Preparing for the AZ-400 Microsoft Azure DevOps Engineer Expert certification can feel overwhelming, especially given the breadth of skills it tests.

From implementing DevOps processes to managing source control, CI/CD pipelines, and infrastructure as code, the exam expects both conceptual clarity and hands-on understanding. Many candidates struggle not because the topics are unfamiliar, but because the exam format itself can be tricky.

One of the most effective ways to overcome this challenge is by using mock exams strategically. Mock exam questions help bridge the gap between theoretical learning and real exam performance.

When used correctly, they not only boost confidence but also sharpen problem-solving skills under exam-like conditions.

This guide explores practical tips and best practices to get the most value from AZ-400 mock exams and avoid common preparation mistakes.
