AZ-220 Microsoft Azure IoT Developer Exam Prep

So the next Microsoft exam in your sights is AZ-220? Me to! I was fortunate enough to sit this exam in April 2021 just before the skills measured changed, so this article is based on the exam I sat. You may want to have a look at the exam skills measured to see what has changed if you are sitting this exam post 23/04/21…. https://query.prod.cms.rt.microsoft.com/cms/api/am/binary/RE4nBeC

This is a wonderful Speciality exam covering all things Azure IoT focussed.

I made this blog post as I was studying toward the exam to contain links to all the resources I utilised during this time. I hope you find this useful to aid your studies!

I spent a fair amount of time working with an Nvidia Jetson Nano device and working through Paul DeCarlo’s amazing Git Repo….. I can highly recommend this as an option to really get hands on:

toolboc/Intelligent-Video-Analytics-with-NVIDIA-Jetson-and-Microsoft-Azure: A repository demonstrating an end-to-end architecture for Intelligent Video Analytics using NVIDIA hardware with Microsoft Azure (github.com)

I also invested in an Azure Dev Kit – MXCHIP that helped cement some ideas. Of course you don’t need to use a hardware sensor, you can use the simulated devices if you like.

Summary

This exam offer a rich a varied set of skills and processes that you can learn, don’t be afraid to roll up your sleeves and work through the MS Learn Modules as well as trying to develop your own little solutions. I have immense fun with a Raspberry Pi and some IoT Sensors and 3d Printed devices as part of this journey. Inspired by the amazing Peter Gallagher, Cliff Agius and Paul DeCarlo to call out some amazing people who are always willing to help.

You can catch both Pete and Cliff on their IoTeaLive Twitch live stream every week on the AzureishLive Channel www.twitch.tv/azureishlive where they regularly have chats around the latest endeavours in the wonderful world of IoT or they invite amazing guests on and work through solutions! Either way I would encourage you to follow the channel and get involved as the guys are immense and always willing to help!

Now I have passed this exam I have no trouble in offering any support I can to anyone wishing to jump on this incredible learning Journey. Feel free to reach out!

This isn’t the end of the journey for me, its just the beginning!!! Enjoy and Good Luck!!!!
