Prerequisites for Azure DevOps Engineer Expert (AZ‑400)
Officially, you must hold either Azure Administrator Associate (AZ‑104) or Azure Developer Associate (AZ‑204) to earn the DevOps Engineer Expert certification. This ensures you already understand core Azure services and how applications run on the platform. Beyond formal prerequisites, it is important to have practical experience with Git, CI/CD concepts, and at least one real project using Azure. Familiarity with Agile or Scrum processes will also make many exam scenarios easier to understand.
Certification Path Table (Azure + DevOps Focus)
You can keep the table as is and support it in text like this:
Start with Azure Fundamentals (AZ‑900) if you are new to cloud or need a structured introduction to Azure concepts. Then move to AZ‑104 if you come from a sysadmin or infrastructure background, or AZ‑204 if you are more of an application developer. Once you earn one associate‑level certification, target AZ‑400 to build expert‑level DevOps skills on top. This sequence gives you a solid foundation in Azure and then layers DevOps practice on top of it.
Preparation Plan for AZ‑400
7–14 days (intensive)
This plan is best if you already design pipelines and work daily with Azure DevOps or GitHub. In the first few days, focus on understanding the current skills outline and mapping it to what you already know. Then spend several days doing targeted deep dives and hands‑on labs in your weaker areas. In the final days, revise using scenario‑style questions and practice exams, and refine your exam strategy and timing.
30 days (balanced plan)
A 30‑day plan is practical for working professionals who can study 1–2 hours per day. Each week, focus on a theme: first get comfortable with the tools and exam objectives, then go deeper into CI/CD and source control, followed by IaC and security, and finally monitoring and practice questions. Mix reading, videos, and documentation with real labs in Azure DevOps to make the concepts stick. By the end of the month, you should be comfortable with both theory and practical tasks.
60 days (paced for beginners to DevOps)
If you are newer to DevOps or Azure, a 60‑day plan gives you enough time to build the right foundations. Use the first month to strengthen your Azure basics and complete an associate‑level certification if needed. In parallel, learn Git, branches, pull requests, and simple CI concepts. In the second month, move into more advanced pipelines, infrastructure as code, security integration, and full scenarios. Finish with multiple practice exams and revisiting any weak topics you identify.
Common Mistakes Aspirants Make
Many candidates focus only on clicking through the Azure DevOps portal and ignore the bigger design and process questions. Others attempt AZ‑400 without real Azure project experience, which makes scenario questions hard to interpret. A common trap is ignoring YAML and relying only on classic pipelines, even though YAML is heavily used in real projects. Some people also overlook observability, feedback loops, and collaboration topics, which are a core part of DevOps and do appear in the exam. Avoid cramming; aim for understanding patterns and trade‑offs.
