In this scenario, Contoso Ltd. must designate a new user named Admin1 as the service administrator of the Azure subscription and ensure that Admin1 receives email alerts about service outages.
In Azure, there are three classic administrative roles associated with subscriptions:
Account Administrator – The individual who created the subscription and manages billing.
Service Administrator – The primary contact responsible for managing services and resources in the subscription.
Co-Administrator – Has the same management privileges as the Service Administrator but cannot change subscription associations.
According to Microsoft Azure Administrator documentation, to change the Service Administrator, you must perform the following steps:
In the Azure portal, navigate to Subscriptions.
Select the specific subscription.
Under Settings, choose Properties.
In the Service Administrator field, update the name and email address to that of the new administrator (in this case, Admin1).
This modification ensures that Admin1 becomes the Service Administrator, and Azure will automatically send service-related notifications and outage alerts to that user’s registered email address, as defined by Microsoft’s subscription notification process.
Option B (IAM settings) is used for Role-Based Access Control (RBAC) and assigning Azure Resource Manager roles such as Owner, Contributor, or Reader. However, RBAC roles do not change the Service Administrator at the subscription level — that’s only done through the Properties blade.
Options C (AAD Properties) and D (AAD Groups) are unrelated to subscription-level administrative settings.
Therefore, the verified and Microsoft-documented answer is:
✅ A. From the Subscriptions blade, select the subscription, and then modify the Properties.
Final Verified Answer: ✅ A. From the Subscriptions blade, select the subscription, and then modify the Properties.
