Currently, Microsoft has not provided specific hands-on labs tailored for the SC-100. Nonetheless, you can still prepare effectively using the following resources:
Practice Assessments: Microsoft Learn offers complimentary practice assessments for SC-100 which help you evaluate your preparation level. Such assessments reflect the style and difficulty of actual exam questions.

Study Guide: The official SC-100 study guide provides outlines of the skills measured alongside pertinent links to relevant learning paths and modules. It’s a great roadmap for your preparation.

Exam Readiness Videos: Visit the Exam Readiness Zone to get some video content focused on providing helpful pointers regarding the structure and content of the exam.
Instructor-Led Training: Even though there is no specific SC-100 course, Microsoft provides instructor-led training sessions for associated certifications such as SC-200, SC-300, and AZ-500 which do offer foundational knowledge beneficial for SC-100.
