Hi Kynan Schwarz,
Thank you for reaching out to us on Microsoft Q&A forum.
Whenever we activate a sandbox in the exercise by clicking on "Activate sandbox" button, we can see a default resource group name starting with learn......(for example: learn-e58d2b0d-5e77-4b91-b751-c67e776463e0) next to --resource-group name as shown in the screenshot below:
If we are unable to see the default resource group name starting with learn...., kindly follow the below options to see the default resource group name for Concierge subscription.
1.Login into the Azure portal with your same credentials used for accessing the learn path. In the Azure portal go to Resource groups and under Resource groups we can see our default resource group name starting with learn...... for Concierge subscription as shown in the screenshot below:
Copy the resource group name and replace [sandbox resource group name] with the copied name by removing the brackets [] and continue the exercise.
2.Even after activation of sandbox, if we are unbale to see the default resource group name starting with learn......, as a workaround kindly go to one unit previous to unit 3: Exercise - Create an Azure virtual machine and come back again to unit 3 to see the default resource group name starting with learn.
