The product documentation also falls under this section. But, using the Microsoft AZ-220 study guide is one of the least structured methods to follow when studying.

Online Reference Courses

There are many online, on-demand video services and courses that can be viewed. Obviously, the cost can vary depending on the source. These offer a great self-paced learning path to follow using audio and video rather instead of written books. These sources can be more natural to consume while multi-tasking.

Books are your Best Friends

Books are always a good learning resource to gain knowledge. Moreover, Microsoft has its own press store. So, never try to limit your knowledge. Therefore, we suggest going through the following AZ-220 books-

Internet of Things for Architects: Architecting IoT solutions
