I’ve already posted preparation resources for SC-200, SC-300 and SC-900, and now it’s time for SC-400 which is different in a few ways to the other exams. The first major difference is that it really is much more focused on protecting Office 365 workloads, rather than the mix of Microsoft 365 and Azure workloads that the other exams cover. It is also different in that this falls into the compliance side of the compliance and security conversation, so it expects you to have an understanding of the Microsoft technologies that focus on content classification, data loss prevention, governance, and protection.

What these differences potentially mean for those of you who want to do this exam is that if you already have a solid understanding of the compliance related Office 365 Enterprise E5 workloads, and have worked with Azure Information Protection, you are probably at a good starting point. Where does that leave you if that’s not where your skills currently are?

Thankfully these gaps will be pretty easy for you to fill, especially when they are workload related. Make sure that you understand the terms that are used for protection inside of Teams, Exchange, and SharePoint, for example, so that you aren’t getting caught out on feature terminology. You don’t need to be an expert in the individual products just mentioned, instead just make sure you’ve been through some introductory concepts that introduce features and terminology. My suggestion is that use Microsoft Learn modules for this, rather than trying to finding the relevant Microsoft Docs pages.
