Hi,
Microsoft Learning is currently not supported in the Q&A forums, the supported products are listed over here https://learn.microsoft.com/en-us/answers/products (more to be added later on).
You can ask the experts in the dedicated Microsoft Learning forum over here:

Basically the Micrsoft Learn modules can be found on GitHub, for the DA-100 you'll find it over here:
