The MS-100 exam, officially titled Microsoft 365 Identity and Services, is the qualifying exam for the Microsoft 365 Certified: Enterprise Administrator Expert certification, which sits at the Expert level. Earning it shows employers that you have the skills the credential stands for, and it is a solid step forward on a Microsoft career path. It also connects to MS-101: Microsoft 365 Mobility and Security, so the effort you put in now keeps paying off as you advance.

The MS-100 exam gives you 40-60 questions to complete within 180 minutes. Do the math before exam day: divide the total time by the question count to set a steady per-question pace, and flag any item that stalls you so you can return to it after securing the easier points. The most reliable way to build that rhythm is a full timed practice test under the same limit, which is exactly what TestSimulate's test engines are designed for.

The passing score for Microsoft 365 Identity and Services is 700, and the official registration fee is USD 165 (varies by region). Keep in mind that a retake means paying that fee again in full, which makes an honest self-check worthwhile: before you book, sit a timed practice test and make sure you are consistently scoring above the passing line with some margin to spare.

According to the official requirements: No formal prerequisites, but MS-100 and MS-101 are both required to earn the Microsoft 365 Certified: Enterprise Administrator Expert certification.. Eligibility rules do change from time to time, so confirm the current details on the official exam page before you register.
