What option should be configured to trigger birthright rules during user import?

The correct choice to trigger birthright rules during user import is Zero Day Provisioning. This concept refers to the provisioning processes that take place on the same day a user is added to the system, ensuring that the user receives all the entitlements and access rights required from the moment they are onboarded.

When targets are imported into the identity governance system, Zero Day Provisioning facilitates the immediate application of birthright rules, which are predefined access rights granted based on specific attributes of a user, such as their role, department, or location. This mechanism ensures that users have the necessary access right away, enhancing security and compliance by preventing delays in access provisioning.

Other options, while they may appear relevant, do not specifically denote the immediate application of birthright rules in response to a user import event. Therefore, Zero Day Provisioning is the most appropriate choice for this context.
