Okta Administrator Certification Practice Exam

Okta Workflows cannot be used to modify the Workday username for provisioning because the integration with Workday has specific requirements and limitations when it comes to provisioning attributes. In general, username modifications are often subject to the underlying system's constraints and can only be managed directly through the Workday system or via supported APIs that Workday provides.

Provisioning typically involves creating and managing user accounts and their attributes based on the source of truth within the identity management layer. Workday has strict policies around usernames that dictate how they can be created, modified, or deleted. As such, altering the Workday username through Okta Workflows is not permitted, making the assertion that it can be done incorrect.

The other choices imply possibilities that may not align with the core functionality of the Workday integration with Okta. The limitations of workflows and their interaction with attributes managed by external systems like Workday clarify that username modification is not a viable operation in this context.
