Zorluk: KolayApp Registrations and Service Principals

When implementing authentication and authorization in Microsoft Entra ID, developers must understand the relationships between different identity objects. Which two of the following statements correctly describe the characteristics or roles of application objects and service principals?

  1. The application object serves as the global definition of the application and remains in the tenant where the application was registered.Cevap
  2. A service principal is the local representation of the application object in a specific tenant and is used to define access policies and permissions.Cevap
  3. C
    A system-assigned managed identity is automatically created as part of the standard application registration process to act as the service principal.
  4. D
    To enable programmatic access for an application running on an on-premises server, you must assign a user-assigned managed identity to the application registration.

Cevap

The correct statements are that the application object serves as the global definition of the application and remains in the tenant where the application was registered, and a service principal is the local representation of the application object in a specific tenant used to define access policies and permissions.
The statement about the application object serving as the global definition in the home tenant is correct because the application object defines the application's configuration globally. The statement about the service principal being the local instance is correct because the service principal acts as the security identity (instance) in each tenant to enforce access policies.

Adım Adım Çözüm

1
Analyze the relationship between application objects and service principals.
Identify that the application object is the global definition of the app, while the service principal is the concrete local instance (identity) created in a tenant to manage access.
This establishes the fundamental distinction between application objects and service principals in Microsoft Entra ID.
2
Evaluate the statements regarding managed identities.
Determine that managed identities (system-assigned or user-assigned) are restricted to Azure resources and cannot be assigned to on-premises applications, nor are they automatically created during standard application registration.
This rules out incorrect options that confuse service principals with managed identities.
