Passed my DP-600 exam yesterday, 58 questions in total with 50 standard questions and 8 questions related to case study. Standard questions mostly related to Microsoft practise exam, some of them are more complex but if you can pass Microsoft practise exam, there shouldnt be a big problem. Also a huge thanks to Will's exam prep videos, very practical and well structured which has helped me a lot to lay a good foundation of Fabric and boost my confidence in taking the exam.
