Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.

Reveal Solution Hide Solution

Correct Answer:

Explanation:

Step 1: Notify all the users in the int1 region and schedule a maintenance window.

Step 2: Select the subscription that was used to perform the initial registration.

Note: You need to change the int1 region to use the capacity model.

Change the billing model and registration name of the int1 region.

The int1 region runs a high number of Windows virtual machines that use pay-as-you-use images.

Change billing model, how features are offered, or re-register your instance

This section applies if you want to change the billing model, how features are offered, or you want to re-register your instance. For all of these cases, you call the registration function to set the new values. You don’t need to first remove the current registration.

# select the subscription used during the registration Select-AzSubscription -Subscription ‘<Registration subscription ID from portal>’

# rerun registration with new BillingModel (or same billing model in case of re-registration) but using other parameters values from portal

Set-AzsRegistration -PrivilegedEndpointCredential $YourCloudAdminCredential – PrivilegedEndpoint $YourPrivilegedEndpoint -BillingModel ‘<New billing model>’ – RegistrationName ‘<Registration name from portal>’ -ResourceGroupName ‘<Registration resource group from portal>’

Step 3: Run the Set-AzsRegistration cmdlet.

You can use Set-AzsRegistration to register Azure Stack Hub with Azure and enable or disable the offer of items in the marketplace and usage reporting.

To run the cmdlet, you need:

A global Azure subscription of any type.

To be signed in to Azure PowerShell with an account that’s an owner or contributor to that subscription.
