Hello !

I am currently preparing the DP-600 certifcation though https://learn.microsoft.com/en-us/training/modules/get-started-data-warehouse/

But I am facing a problem. when trying to launch the exercice part of the : https://learn.microsoft.com/fr-fr/training/modules/get-started-data-warehouse/7-exercise

I get this page error when I clik on the "Launche Exercise" button.

Any idea of if I can access the same exercise any where else?
