Where Can I find Training Material for AZ-104 Course?

In Video It is asked to Locate the nsg-prep-infra.ps1 script in the “050- Administer Virtual Networking” folder of your training materials but I don’t know where to find training material firstly.

Please check in the course repo. I think you will find the file there.

I Have already tried there not able to find the file. Can you please check course and then reply.

Thank you so much. Able to find with your given link. I believe its a bit complex structure.
