Prerequisites for Taking the Exam

Experience with Microsoft Azure

The AZ-400 exam is for people pursuing the Microsoft Certified: Azure DevOps Engineer Expert certification. To take this exam, individuals need to have passed the Microsoft Certified Azure Administrator Associate or Microsoft Certified Azure Developer Associate certifications.

The exam format includes multiple-choice questions, multiple-response questions, case studies, and other question types. Topics covered in the exam include design secure development and compliance, implementation of continuous delivery, infrastructure as code, version control, configuration management, and the implementation of continuous feedback.

Having a practical understanding of these topics is important to succeed in the exam and show a comprehensive knowledge of Microsoft Azure DevOps Solutions.

Familiarity with DevOps Solutions

DevOps solutions are important for the AZ-400 exam. Candidates must understand how to integrate, build, and release code using DevOps tools. This includes CI/CD pipelines, release strategies, and compliance and security. Knowing best practices for version control, compliance, infrastructure as code, configuration management, and application infrastructure is also necessary.

Practical experience with DevOps principles and hands-on experience with tools like Azure DevOps, GitHub, Jenkins, Azure App Services, and Azure Kubernetes Service is crucial. The exam requires candidates to show their ability to design and implement DevOps practices. A solid grasp of these concepts and tools is essential for success.

Format of the Exam

Types of Questions

The AZ-400 exam has different types of questions. These include multiple-choice, drag-and-drop, and case study questions. Each type requires different problem-solving skills.

Multiple-choice questions require choosing the best answer from a list. Drag-and-drop questions test the ability to arrange components in the correct sequence.

The time given for answering each type of question varies. Multiple-choice questions take less time, while case study questions need in-depth analysis and take more time.

Candidates need fundamental knowledge of Azure administration, software development, security, compliance, and flow design. Hands-on experience with Azure services, DevOps, and development processes is also recommended.

Understanding these concepts and question types will help candidates prepare for the exam confidently and successfully.

Time Allotted

The AZ-400 exam lasts three hours. Candidates should manage their time carefully during the exam to complete each section within the allocated time. Not following the time limit could lead to unfinished sections, missing important questions, and a lower score. Effective time management enables candidates to review their answers, ensuring accuracy and completeness for the best possible result. It's also important to regularly check the remaining time to plan the completion of each section.

Before the exam, candidates should practice time management strategies to get used to the time restrictions and be fully prepared.

Course Outline and Topics Covered

Configuring Processes

Configuring processes is important for improving efficiency and productivity within a team. When configuring processes for Microsoft Azure DevOps solutions, it's important to consider the team's specific needs, the project's goals and objectives, and the available resources.

Strategies to effectively configure processes for source control, build and release pipelines, and security and compliance planning include identifying bottlenecks and areas for improvement, establishing clear and concise workflows, and implementing automated testing and validation processes. By carefully configuring processes, teams can streamline their development and deployment workflows, enhance collaboration, and ensure the security and compliance of their projects.


To take the AZ-400 exam, candidates need to know Azure, DevOps, and software development. It's helpful to also have practical experience with these technologies, a strong understanding of programming concepts, and Agile practices.

The exam has multiple-choice questions and case studies. It tests candidates on their ability to design secure, scalable, and reliable solutions that meet business objectives. It also evaluates proficiency in building, testing, and maintaining cloud applications and services, implementing and automating CI/CD pipelines, and monitoring and optimizing solution performance.

A comprehensive understanding of these topics and hands-on experience using Azure DevOps and other relevant tools are important for successfully passing the AZ-400 exam.

Source Control

Source control is important in development. It helps track and manage code changes, allows collaboration, and maintains revision history. This ensures code integrity and consistency. Source control tools, like Git and Subversion, enable parallel development and provide a single code truth. They offer features such as branching, merging, and conflict resolution. These tools are easy to use and integrate with other development tools.

Source control is vital for efficient collaboration and code management in modern software development.

Build and Release Pipelines

Build and release pipelines play a big role in DevOps solutions. They help with the software development and deployment process by automating the building, testing, and deployment of software. This makes sure that the code is consistently delivered to the production environment.

Best practices for effective build and release pipelines include setting up automated testing, reliable version control, and implementing continuous integration and continuous deployment (CI/CD) processes.

This allows organisations to maintain a streamlined and efficient development workflow, ensuring that the software is consistently tested and deployed without any manual intervention.

Following these best practices helps organisations ensure a smooth and efficient software development and deployment process, resulting in better quality software and faster time to market.

Security and Compliance Plan

Azure DevOps Solutions ensures security and compliance through various measures. This includes user authentication, data encryption, and role-based access control. These measures protect sensitive information and prevent unauthorized access. Regular security audits and compliance checks are also conducted to address potential vulnerabilities.

The security and compliance plan is seamlessly integrated into the AZ-400 course outline. This involves specific modules and practical exercises focusing on security best practices, compliance requirements, and the implementation of secure development processes within Azure DevOps. This equips candidates with the knowledge and skills to address security and compliance throughout the software development lifecycle.

Instrumentation Strategy

The goal of the instrumentation strategy is to make the AZ-400 exam more efficient and effective. It aims to understand the exam process and user behaviors to find areas for improvement.

The strategy will be integrated into the development and deployment process by adding monitoring and performance analysis tools to the exam environment. This allows for real-time data collection and analysis without affecting the candidates' exam experience.

Implementing the strategy will involve using tools like logging frameworks, performance analytics platforms, and user behaviour tracking tools. These tools will give a complete view of the exam, from user navigation to system resource usage.

This data will be used to continuously enhance and optimize the exam experience, ensuring it meets high standards of reliability, security, and performance.


The Microsoft AZ-400 exam is known for its wide range and the requirement to show advanced skills in DevOps practices and principles. Candidates need to be skilled in areas like designing and implementing strategies for collaboration, code, infrastructure, and compliance. They also need to implement continuous integration and continuous delivery, and monitor and optimize a DevOps pipeline.

To pass the exam successfully, thorough preparation and practical experience are required.
