Which of the following statements is true about Auto-Populate?

The statement that auto-populate automatically returns values for all properties on a page or page list when the ID property is provided is accurate. This feature is designed to streamline data retrieval processes. When an ID property is specified, auto-populate can efficiently pull in related data for all corresponding properties on a given page or within a page list without the need for additional specification of each individual property. This capability is particularly useful in scenarios involving database interactions where referencing an ID can facilitate the retrieval of comprehensive data seamlessly.

Other statements do not convey the same level of accuracy or scope of functionality inherent to the auto-populate feature. For instance, while auto-populate has data-handling capabilities, it is not universally enabled for all data scenarios by default or requires any property value to be set in order to populate all properties, which can lead to confusion. Thus, the correct choice emphasizes the automated retrieval efficiency when an ID is provided, showcasing the practical utility of this feature in the Pega system.
