Correct Answer: A, BWhen you configure an Azure subscription to use a different Azure Active Directory (Azure AD) tenant, it results in the loss of specific configurations related to the original tenant. Firstly, role assignments at the subscription level, which are associated with the Azure AD users, will be lost as these assignments are based on the identities in the original Azure AD tenant. Secondly, virtual machine managed identities are tied to the specific Azure AD tenant, thus changing the tenant will invalidate these managed identities, necessitating their reconfiguration. Existing resources like virtual machine disk snapshots and Azure resources themselves will not be deleted as they are not directly related to the Azure AD tenant.
