Which event should be triggered when user facing info, warning or error messages need to be displayed on a Visualforce page?
Correct Answer: D
The event that should be triggered when user facing info, warning or error messages need to be displayed on a Visualforce page is pageMessage. This event is triggered by the displayPageMessage method of the CCRZ.util class, which is a utility class that provides various helper methods for common tasks. The event can be used to display a message on the page with a specified type, title, and text. For example,CCRZ.util.displayPageMessage('error', 'Oops!', 'Something went wrong.')will trigger the pageMessage event and display an error message on the page.
