Adobe Exam AD0-E312 Topic 4 Question 30 Discussion

A Campaign developer receives a request to attach a file to each email in a campaign.

There are three variations of the attachment. The filename to be attached must be based on a recipient-level derived field: attachmentSegment. The derived field is created in an enrichment activity and carried through as additional data with the target population.

The developer will select File Name is Computed during delivery for each message and use a computed filename.

How should the developer set the attachment computed filename for the three attachments located in the C: \tosend directory?
