My Journey to Pass the AZ-400 Certification with Updated Practice Tests

I am a DevOps engineer from USA, I got Azure DevOps certification and passed with a good score. In this post, I'd like to share a bit of my experience, resources, and steps that I took that helped me as I prepared for the Azure DevOps certification exam.
The Azure DevOps Expert certification is a 3-star certification that is included in the Microsoft Expert-level certifications.
As a professional, certifications provide industry-backed proof of mastering skills in your area of expertise.
The Pearson VUE Value of IT Certification Survey states that 91% of certified IT professionals gain more professional credibility, 89% are more valuable to their employers, and 35% of surveyed candidates reported a salary increase / salary as a benefit of getting certified. The Microsoft Certified: DevOps Engineer Expert certification is no different when it comes to the benefits mentioned above.
Microsoft Certified: DevOps Engineer Expert, codenamed AZ-400, is an exam that validates the skills of subject matter experts working with people, processes, and technologies to deliver business value on an ongoing basis.


A candidate for this exam must have written one or both Microsoft certifications. I chose to write Azure Developer Associate due to my experience as a software developer.
Microsoft Certified: Azure Partner Developer
Microsoft Certified: Azure Associate Administrator

You can schedule or reserve your AZ-400 exam quite easily. You can choose to take your exam at a testing center or at your office / home, whichever is most convenient for you. The cost of the exam is different depending on the country from which you take it.

Taking your exam

It is important that you arrive at your test center between 15 and 30 minutes before your scheduled appointment time. This will give you enough time to complete the necessary login procedures. If you are more than 15 minutes late for an exam and are denied admission, exam payments and shipping fees must be made.
Be prepared to show two (2) valid forms of personal identification, a national identity card, a driver's license, or an international passport.


• Please mark the questions you are unsure of the answers to review and re-examine them when you are done with the others.
• Please do not leave any AZ-400 questions unanswered and be sure to submit them before moving on to the next section.
• The case study questions come after the first section.
