This question indeed appears to be outside of the scope of the exam - which should, in general, be based on Microsoft Learn content. You can find more at https://docs.databricks.com/api/azure/workspace/tokenmanagement/getpermissions
The following content might be helpful : https://learn.microsoft.com/en-us/azure/databricks/admin/access-control/tokens - but, my opinion, it's insufficient in this case
Btw. keep in mind that you do have access to MS Learn during the exam.
