Full Detailed In-Depth Explanation:

In Oracle Global Human Resources Cloud, the Person Name Format configuration within the "Manage Workforce Information" task allows customization of how names are displayed across the application. This is distinct from defining name fields or their required status, which is handled elsewhere (e.g., via flexfields or page composer).

Option A: You can configure the display format of a worker’s name (e.g., "First Last" or "Last, First") at the top of employee-level pages, such as the Employment Info page. This is a key feature of the Person Name Format task, making it correct.

Option B: The name fields shown in the Person Details section during hiring are predefinedby the system or customized via page composer/flexfields, not directly through the Person Name Format task, which focuses on display format rather than field visibility.

Option C: The format of a worker’s name in search results (e.g., Directory or Person Search) can be configured here, allowing consistency in name presentation across the application. This is a supported feature, making it correct.

Option D: Defining required name fields (e.g., First Name as mandatory) is managed through the Person Details setup or flexfield configuration, not the Person Name Format task, which is about display rather than data entry rules.

The correct answers areAandC, as confirmed in "Implementing Global Human Resources" under Workforce Information setup.
