AZ-220 Study Guide: Microsoft Azure IoT Developer

If you are a Developer focusing on Internet of Things (IoT) solutions on Microsoft Azure, then the AZ-220 Microsoft Azure IoT Developer is for you. I am currently preparing for that exam, so I want to share my AZ-220 Microsoft Azure IoT Developer Certification Exam Study Guide with you. If you are passing the AZ-220 exam, you will earn the Microsoft Certified: Azure IoT Developer Specialty certification, that you understand how to implement the Azure services that form an IoT solution, including data analysis, data processing, data storage options, and platform-as-a-service options. IoT Developers must be able to recognize Azure IoT service configuration settings within the code portion of an IoT solution.

To learn and prepare for the exam, I usually use a couple of online resources, mainly Microsoft Docs and Microsoft Learn, which I am going to share with you. You can find more information about how I prepare for a Microsoft Certification exam on my blog post: How to prepare and pass Microsoft Certification Exam.

AZ-203 Microsoft Certified Azure Developer Associate

Passed AZ-203 Microsoft Certified Azure Developer

I am happy to share that I just passed another Microsoft Azure Exam. This time I took exam AZ-203, which gives you the Microsoft Certified Azure Developer Associate. This exam is focused on Azure Developers building solutions using different Azure services. There are several various Azure exams and certifications depending on different job roles like the Microsoft Certified Azure Administrator Associate or the Azure Architect Expert. However, even as an architect, engineer, or administrator, it helps how to understand different Azure services and how you can implement, design, and use them. These exams are not focused on writing the perfect code; they are designed to understand how you can design and build solutions and applications on top of the Azure platform. As you can see on the exam page, the AZ-203 has different focus areas like Azure IaaS, containers, app services, serverless, databases, storage, security, and much more. If you want to prepare for the exam, I highly recommend that you check out Microsoft Learn, but more on that later.

AZ-203 Microsoft Certified Azure Developer Associate

Candidates for this exam are Azure Developers who design and build cloud solutions such as applications and services. They participate in all phases of development, from solution design, to development and deployment, to testing and maintenance. They partner with cloud solution architects, cloud DBAs, cloud administrators, and clients to implement the solution.

You can find more about the exam and more details on the Microsoft Learning platform. The AZ-203 exam will be replaced by the new AZ-204 exam, you can check out my AZ-204 Developing Azure Solutions Exam Study Guide.

Azure Certifications

As mentioned, Microsoft offers different certifications depending on various job roles. If you are just getting started with Azure, I also highly recommend that you are doing AZ-900, which is the Azure Fundamentals exam.

How to prepare for the AZ-203 Microsoft Certified Azure Developer Associate exam

Microsoft Learn Azure Modules

For every modern Microsoft exam, I recommend that you first carefully read the skills measured on the exam page. Knowing the technologies and topics which are tested in the exam is already half of the work. Next, I recommend that you have a look at Microsoft Learn. Microsoft Learn is a great learning platform with a lot of different modules on different topics and technologies, which you can search but also filter based on your role. These are not just text-based learning modules; in some cases, you have a hands-on experience using a sandbox environment. You need to work with these technologies, try out these services on Azure, read the documentation on Microsoft Docs to the specific topics and go and try out the services with the different quick starting guides and tutorials. This will not only help you learn for the exam but also provide you a lot of knowledge on Azure.

I wish you happy learning and good luck taking the AZ-302 Microsoft Certified Azure Developer Associate exam!



Microsoft Azure Certifications

New Microsoft Azure Certifications announced

This week Microsoft Inspire takes place in Las Vegas. Unfortunately, I couldn’t make it this year. However, some of my colleagues from itnetX Switzerland and itnetX are there, don’t miss them and visit our booth! During the first day keynote at Microsoft Inspire, Microsoft quickly announced three new Azure Certifications for Administrators, Developers, and Architects. You can already take the beta exams for the Azure Certified Administrator with more information on the Microsoft Learning Blog.

New Microsoft Azure Certifications

The three new Microsoft Azure Certifications are:

  • Microsoft Certified Azure Developer
  • Microsoft Certified Azure Administrator
  • Microsoft Certified Azure Architect


MCSD Azure Solution Architect

Passed MCSD: Azure Solutions Architect

Today I just passed the last Microsoft Azure exam for the MCSD: Azure Solutions Architect. Since I focus on Microsoft technology, I always try to be certified in the specific areas where I am focused on. With Public and Hybrid Cloud scenarios becoming more and more important, I started to work with Microsoft Azure and other Microsoft Cloud Services such as Office 365, so it made sense to learn more about the solutions and earn the certifications. For the Azure part, Microsoft has a certification called MCSD: Azure Solutions Architect, which includes three different exams:

  • 70-532 (Developing Microsoft Azure Solutions)
  • 70-533 (Implementing Microsoft Azure Infrastructure Solutions)
  • 70-534 (Architecting Microsoft Azure Solutions)

I already go 70-533 at the beginning of this year, since this was the topic I was working with for quite some time. With Developer and DevOps scenarios becoming more and more important, I decided to prepare also for 70-532, which is focused on the Developer site of Azure, and the 70-534, which is an overall architecture exam. Bringing IT Pro and Developer skills together in this Cloud-focused world makes sense. IT Pros will have to learn some necessary developer skills to make sure they can keep up with the fast-moving cloud world. I am proud the be the second certified MCSD: Azure Solutions Architect within itnetX, after Marcel Zehner. This shows our strong focus, knowledge, and commitment to the Microsoft Cloud Strategy. If you want to do the exams as well, here are some recommendations:

  • Get a Microsoft Azure Subscription and start playing and testing. Btw, this is something you should have done a while ago.
  • Learn PowerShell, well I have been saying this for years now, learn PowerShell and get some knowledge on that topic, even if it’s not Azure related.
  • Install Visual Studio. Yes, you will need this in the future, not just for the exams.
  • Check out the Microsoft Certification page and learn about the exams and which skills are measured. Login to Azure and start working with these topics. To be honest, it doesn’t take a lot of time to build some demos.
  • Check out the Microsoft Virtual Academy (MVA) courses. Microsoft offers some great exam preparations and courses with several hours of video content, examples, and preparation questions.
  • Check out the current Azure Portal and the new Preview Azure Portal.
  • Look out for some great blog posts with study guides, for example, from Keith Mayer, Anders Eide, and Marius Sandbu.

With that you will not only pass the exams, you will also learn a lot about how things are going to work in the future.
