Hi Corentin Cordier,
Thank you for reaching out to us on Microsoft Q&A forum.
We see that you are facing an issue during your training on Microsoft Learn path as mentioned below:
Subject : Microsoft Certified-Azure Fundamentals
Learning Path: Microsoft Azure Fundamentals: Describe Azure architecture and services.
Module : Describe Azure compute and networking services
Unit 3 of 14 : Exercise - Create an Azure virtual machine.
To complete Unit 3 of 14, Exercise - Create an Azure virtual machine, we don't require any personal Azure subscription. We require a Sandbox to complete this module. Sandbox provides a default subscription called "Concierge Subscription". When we click on "Activate Sandbox" button, by default sandbox creates a resource group, assigns a role, creates a storage account and file share required for cloud shell under "Concierge Subscription". The Sandbox automatically cleans up all the resources along with resource groups when we finish working with a module. As mentioned in the learn path, the module specifically uses Azure CLI to complete the Task-1 and the exercise by using a sandbox.
Kindly note that you will also have the option of using the Azure portal during sandbox exercises. You need to use only the link provided in the exercise to access the Azure portal. Using the provided link in the exercise ensures that the correct subscription is used, and the exercise remains free for you to complete.
If we open the Azure portal from your personal subscription instead of Sandbox subscription (i.e., Concierge Subscription) to complete the exercise, we need to create resources like storage account and file share to get connected to the cloud shell. And this incurs a small cost. Resources that you leave running can cost you money. You can delete resources individually or delete the resource group to delete the entire set of resources after completing the exercise in the module. Kindly find the screenshots attached here for reference from Azure portal:
After creating storage account and file share in the Azure portal we can connect to the cloud-shell as shown below by clicking on cloud-shell icon:
To complete Task 1: Create a Linux virtual machine and install Nginx, we need to first activate the sandbox by clicking on the "Activate sandbox" button. After activation of sandbox, we can see the screenshot as below:
Kindly follow the steps as mentioned in the module to complete the exercise using Azure CLI.
Kindly ensure to complete the exercise with in 1 hour after Activating the Sandbox.
If you are still running into issues, kindly attach the screenshots for reference and please let us know in the comments. We are glad to help you.
