DevOps is a set of practices that combines software development (Dev) and information technology (IT) operations (Ops). It aims to reduce the systems development life cycle and provide continuous delivery of high-quality software. DevOps works in tandem with Agile software development; several DevOps features stem from the Agile methodology.
Note: DevOps has no single, universal certifying body or exam. This page focuses on Microsoft's AZ-400: Designing and Implementing Microsoft DevOps Solutions exam, which leads to the Microsoft Certified: DevOps Engineer Expert credential. Other DevOps-related credentials exist too, including the DASA DevOps Fundamentals certificate, DevOps Institute/PeopleCert certifications, and the AWS Certified DevOps Engineer – Professional exam — check which one your employer or target role actually requires.
DevOps practice test questions are only for self-evaluation. By taking an online DevOps practice test, you can assess your DevOps knowledge, which is required to successfully complete a certification. After passing these practice tests, you will have mastered the skills needed to pass the final exam with flying colors and will be able to apply this knowledge in your daily work.
Prerequisites vary by which DevOps certification you pursue. Microsoft's AZ-400 exam has no strict enforced prerequisite, but Microsoft recommends candidates have hands-on experience administering and developing on Azure plus experience with GitHub and Azure DevOps. Vendor-neutral certifications (like DASA DevOps Fundamentals) have no technical prerequisites at all. The skills below will help with most DevOps exams: Practice with the free DevOps practice test on PracticeTestGeeks (150+ questions with answer explanations).

Prepare for the DevOps exam with our free practice test modules. Each quiz covers key topics to help you pass on your first try.
Exact format varies by which DevOps certification you take. For example, Microsoft's AZ-400 uses a mix of multiple-choice, case studies, and scenario-based questions with a passing score of 700/1000. Vendor-neutral foundational exams (like DASA DevOps Fundamentals) are typically shorter, around 40 multiple-choice questions in 60 minutes, sometimes with extended time available for non-native English speakers. Always check the official page of the specific certification you're registered for.
Agile Development Teams can use DevOps to implement Continuous Integration and Continuous Delivery. This enables them to bring products to market more quickly.

22. An lT organization wishes to test their new DevOps practices on an upcoming release. Which of the following does NOT constitute a good pilot?
Answer: D. Enough to demonstrate the return on investment in DevOps.
A good pilot project for new DevOps practices should be manageable, have a high chance of success, and be large enough to demonstrate the benefits and earn the right for future improvements. While demonstrating ROI is a long-term goal of DevOps, a pilot project itself might not be 'enough' to fully quantify the comprehensive ROI across the entire organization. Its primary purpose is to prove the concept, learn, and build confidence, not necessarily to provide a complete financial justification.
9. Which DevOps practice backs up The Second Way?
Answer: A. Peer review of production changes
The Second Way of DevOps, the 'Way of Feedback,' emphasizes creating and amplifying feedback loops to prevent problems from recurring and to learn from failures. Peer review of production changes directly supports this by providing a critical feedback mechanism before changes impact users. It allows for early detection of potential issues, knowledge sharing, and learning from others' perspectives, thereby shortening and improving feedback loops.
What is Prometheus primarily used for in a DevOps environment?
Answer: A. Collecting and storing time-series metrics with a pull-based model
Prometheus is an open-source monitoring system that scrapes metrics from instrumented targets at defined intervals and stores them as time-series data.
5. Which of the following is a DevOps business value?
Answer: C. Productivity
DevOps aims to improve the overall efficiency and effectiveness of software delivery, which directly translates into business value. Increased productivity is a key outcome, as streamlined processes, automation, and improved collaboration allow teams to deliver more features and value in less time. While other options are important operational metrics, productivity represents a broader, direct benefit to the business.
