Hi!
I have passed the SC-100 exam around 10 days ago.
Got around 50 questions in all, including few YES/NO questions and few Hotspot questions and few D&D questions and 2 Case Studies, no LAB questions.
2 Case Studies are: Fabrikam, Inc. and Litware, Inc. Each item has around 10 questions.
The SC-100 exam measures your ability to design, integrate and develop a security strategy for your organization based on the topics from the official study guide.
By the way, I am glad to share my SC-100 exam study materials, if you need them, PM me ASAP.
Good luck!
