Preparing for the MS-100 Microsoft 365 Identity and Services Exam (BETA)

Check out the updated version of this prep guide here!

Capture With the retirements of Microsoft’s 70-346 and 70-347 Office 365 exams next year, it’s time to start looking at the new exams that are currently in beta. MS-100 Microsoft 365 Identity and Services is very heavily focused on technologies in the 70-346 exam, but also adds some elements from 70-347, as well as bringing in elements of the Enterprise Mobility + Security suite, primarily in the shape of Azure Active Directory Premium questions.

One of the things that is getting easier as far as content preparation sources go is that docs.microsoft.com is going to feature more prominently in your study for this exam. Instead of providing lots of links per item, I’ll start with just one or two if the articles provides enough of a launchpad to get you moving in the right direction. I’ll update it over time, so if you’ve got any suggestions let me know. I’d rather point to official documentation rather than blog posts that may not be updated, and now that large portions of the Office 365 content has moved to docs.microsoft.com we can see the latest update details for the page.

If you don’t have a test environment to help you prepare, you could set up a free Azure subscription if you need an environment to build virtual machines, and add the trials for Office 365 E5 and EMS E5 trial subscriptions. The number of virtual machines you need will be determined heavily by how you want to test out the different Azure Active Directory Connect and Active Directory Federation Services. If you are you also planning on doing MS-101 Microsoft 365 Mobility and Security exam, you might be better off downloading the Modern Desktop Deployment and Management Lab Kit from the Microsoft Evaluation Center. It’s a big download (26.5GB at time of writing) but will help with some of the additional scenarios you will need to prepare for and save a huge amount of setup time.
