Hello!
Passed MS-100 exam last week (09/Sep/2022).
I had 45 questions in all, got 4 Case Study questions and 1 LAB (8 tasks) and some YES/NO questions.
Got around 15-18 new questions including new HotSpot questions and New Drag and Drop questions.
And, I have collected all LABs and HotSpot questions Drag and Drop questions which may appear in the actual MS-100 test, if you need, I am glad to share those MS-100 study materials.
Good luck!
