Microsoft 365: Fundamentals (MS-900) Exam Prep Guide

This blog is part of a series. For more exam prep guides check back in the future

LAST UPDATED: 26/08/2019 (v.3.0)

I’ve always liked and recommended Microsoft Fundamentals exams. Last year, before this new generation was created, I went back to gap fill my Office 365 MCSA with the Cloud, Mobility and Security Fundamental MTA’s (98-367, 368, 369). And even though these new generation MCF’s – like MTA’s – are optional (they don’t count towards the associate workloads) I don’t personally believe in bypassing them. No shortcuts. But Others may disagree. I respect that.

Microsoft 365 Fundamentals is the natural successor to the Cloud Fundamentals (98-369) MTA. It’s about understanding the components of Microsoft 365 and the concepts which underpin it. It’s about what those components are designed to do and how they can be deployed and managed. It’s also about SKU’s and Support offerings. Now – even with this last element – it would be a mistake to assume that this exam isn’t technical. Yes, it won’t go into the nuts and bolts of the workloads, but there is a lot of value of understanding broad concepts at a high level.

If you have never taken a fundamentals exam in the past, it’s typically around 60 minutes once past the regulations and usually has between 45 and 55 questions so you must think on your feet. Sometime during 2019 there should be an official practice test and MOC courses are available (I know this as I teach them). The short form course has surfaced on Microsoft Learn here and I have since found an effective Open EDX course to supplement learning here. Bear in mind that the MCF’s are also about broader concepts as opposed to very defined subject matter so it’s more than simply using for definitive articles. A combination of docs, Learn, the MOC course, the Microsoft product, licencing and trust websites, the Microsoft 365 Blog and the Microsoft 365 Partner site should be enough.

Important Note: this exam prep guide should be used to supplement your own resources and should not be used for the whole of your learning. Some of the resources may be not completely cover the requirements especially if the requirement is vague. If you find better articles than the ones below, please feel free to reach out and I’ll amend.
