Microsoft Certified - Azure Developer Associate (AZ-204) Study Guide

This study guide is aligned with the latest exam changes done on March 26, 2021.

The Microsoft Certified: Azure Developer Associate certification enables you to implement solutions on Azure while leveraging the tools and services available. This is an intermediate level certification, so I would recommend you to set aside some time to study for the exam and practice using some of the services related to this exam - ‘Practice makes perfect’ In this study guide, I will share with you some of the useful resources you can use to guide you during your learning path to get this certification.

Exam AZ-204: Developing Solutions for Microsoft Azure

The AZ-204 has a length of two hours. There are 45+ questions and you need a minimum of 700 of 1000 points to pass the exam.

The first place to go is the Microsoft Learn platform where a dedicated learning path is available, for free. Also, you should have a look at the Resources section in this study guide where you have useful resources to help you consolidate the knowledge that will help you get the exam and certification. If you prefer to watch videos, instead of reading, explaining these core concepts, and showing how to get prepared for the exam, then I invite you to have a look at the Developing Solutions for Microsoft Azure (AZ-204) path, available on Pluralsight.
