Last week I passed (result) the new MB-400 exam: Microsoft Power Apps + Dynamics 365 Developer. I really wanted to take this technical exam because in the past all exams were based on configuration, customization and functional modules. For those like me who have a focus on the technical aspects, this exam is really interesting for its contents and it is beautiful to prepare and study it. I anticipate that it is hard as there are many aspects and above all it is based on all the innovations of dynamics 365 and power platform.

To prepare it, in addition to the experience, I invested about 2 weeks. In addition to following the official Microsoft paths MB400 and PCF, I found many links (thanks to Joe Griffin) on the web that I used to study in addition to my blog where I have many articles on PCF. Having also passed the MB-200 Core exam in the past, with this new MB-400 exam I obtained the new certification Power Apps + Dynamics 365 Developer Associate.

Finally, if you plan to study and take this new exam MB-400, I prepared for you this study guide following the official certification outline.
