A brand wants to do an ad-hoc export of new user-defined attributes, what option would they choose?

When performing an ad-hoc export of a segment, Marketing Cloud Personalization provides an option to include user-defined attributes. These are referred to as "custom fields" in the export configuration. Selecting this option ensures that all custom profile attributes captured for the users within the segment are included in the resulting CSV file, allowing for detailed analysis or use in other systems. This is the direct method for exporting newly created attributes.

A. Excluding anonymous fields is a data filtering option, not a method for including specific new attributes for known users.

C. Including built-in fields exports standard Personalization attributes, not the "new user-defined" ones specified in the question.

D. Sending segment data to Marketing Cloud is about the destination of the data, not configuring the content of an ad-hoc file export.
