I have been studying MD-101 and doing the labs provided to this course. Sorry to say but out of 3 labs i done so far only one has worked as expected.
I got two tickets open @ Practice labs regarding:
Configure Windows AutoPilot
Implement Windows 10 Provisioning Package
They have confirmed there are errors in the above labs.
I went for ITPRO Premium plan for the labs but I believe the failure rate is to big. Hopefully ITPRO got a strong collaboration with Practice labs so the MD-101 labs will be checked asap.
