In some cases, your Azure tenant has multiple Azure subscriptions. Every time, when you sign-in into Microsoft Azure using PowerShell, you would get this warning: WARNING: TenantId '615dc844-35d3-40c2-9db4-0439991ec82e' contains more than one active subscription. First one will be selected for further use. To select another subscription, use Set-AzContext. To override which subscription Connect-AzAccount selects by default, use `Update-AzConfig -DefaultSubscriptionForLogin 00000000-0000-0000-0000-000000000000`.
