Common Questions About the Microsoft MS-100 Exam

What is the Microsoft 365 Identity and Services exam all about?

The MS-100 exam is the official Microsoft exam behind the Microsoft 365 Certified: Enterprise Administrator Expert certification, validating the skills measured by the Microsoft 365 Identity and Services credential. It sits at the Expert level of the Microsoft certification program. It also connects to MS-101 Microsoft 365 Mobility and Security, Microsoft 365 Certified: Administrator Expert, so the knowledge you build here carries over to those tracks as well.

How many questions are on the MS-100 exam, and how much time do I get?

The MS-100 exam contains 40-60 questions to be completed within 150 minutes. Before exam day, divide the available time by the question count to work out a comfortable per-question pace, and mark any item that eats into it so you can return later instead of getting stuck. Timed sessions in the Getcertkey test engines make that pacing automatic — run at least two full-length mock exams under the clock so time pressure never becomes the reason you drop points.

What score do I need to pass the MS-100 exam, and what does it cost?

The passing score for the MS-100 exam is 700 / 1000, and the official registration fee is USD 165. Retakes are not discounted — every new attempt means paying the full fee again — so it pays to measure yourself before you book. Work through the 431 practice questions on Getcertkey, sit a timed practice test, and schedule your exam only when your scores are consistently comfortable. That simple habit is the cheapest exam strategy there is.
