What additional resource is created in Azure AD when an enterprise application is registered?

• A. a service principal
• B. an X.509 certificate
• C. a managed identity
• D. a user account

Answer: (A)

When an enterprise application is registered in Azure Active Directory (Azure AD), a service principal is created as part of that process. The service principal serves as the identity of the application within the directory. It enables secure interactions between the application and Azure services by allowing users and applications to authenticate and authorize access to resources. A service principal is essential for representing the application in Azure AD, ensuring that the application can perform actions as defined by its permissions and roles. This mechanism provides a way to control access to resources in a granular way, enabling the application to operate within the scope granted to it by administrators. Creating a service principal is particularly important for scenarios where automation or managed identities need to interact with Azure resources. This allows applications to talk to Azure services securely without requiring user credentials, thereby enhancing security and simplifying management. The other options do not directly result from the registration of an enterprise application. An X.509 certificate is often used for specific authentication scenarios but is not created automatically with the registration of an enterprise application. A managed identity is a different feature tied to Azure services that provide identity for use with Azure resources, while a user account represents a person rather than an application.
