The AZ-400: Designing and Implementing Microsoft DevOps Solutions exam itself doesn’t have any specific technical prerequisites. However, to earn the Microsoft Certified: DevOps Engineer Expert certification associated with the exam, you need to fulfill one of the following requirements:

• Pass either the Microsoft Certified: Azure Administrator Associate (AZ-900) or Microsoft Certified: Azure Developer Associate (AZ-204) exam. These exams demonstrate a foundational understanding of Azure services and concepts, which are relevant to DevOps practices.
• Hold an existing Microsoft certification that validates your expertise in cloud technologies and aligns with the DevOps Engineer Expert role. This could include certifications like Azure Solutions Architect Expert (AZ-305) or Microsoft Certified: Azure Security Engineer Associate (AZ-500).

While there are no formal prerequisites for taking the AZ-400 exam, Microsoft recommends that you have:

• Experience with administering and developing in Azure: Familiarity with Azure services like Azure DevOps, Azure Active Directory, Azure Resource Manager, and others is beneficial.
• Strong skills in at least one of these areas: Azure DevOps, GitHub, continuous integration and continuous delivery (CI/CD) pipelines, infrastructure as code (IaC), and DevOps security practices.
