I have enrolled in Databricks Platform Administration Fundamentals and on the Demo: "Using Databricks Utilities and CLI" it require"  you  to " open this Notebook in your workspace: 1- Using Databricks Utilities and CLi" 

Where does one obtain this Notebook? No information is provided. 

I.e. did I miss a module with content to download or credentials to use in a test environment? Or is this provided with a corporate Databricks account?
