Question 24

Question

DRAG DROP You are developing a Power Platform app for a school. The school plans to use the app to gather information about classes and students. You must design a plug-in for the app. You must store data about students in the Contacts table and store data about classes in a custom table. You need to select the stage in the event pipeline for each function. Which stages should you use? To answer, drag the appropriate plug-in stages to the correct functions. Each plug-in stage may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content. NOTE: Each correct selection is worth one point. https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/PL-400/page_258_img_1.jpg

Not totally sure here but I think it goes like this: Cancel a class if the student is over 15 years old -> PreValidation, Update the record and rollback if error -> PreOperation, Add a student to class -> PostOperation. Does this look right to anyone else?

Ivy L. · Answer

PreValidation maps to cancel (age check before logic runs), PreOperation is for updating and rollback since it's still in transaction, PostOperation for adding the student to class after save. That's basically how Dataverse plugin stages line up, unless I'm missing a rare edge case.

OliviaG · Answer

PreValidation for cancel (early validation before process starts), PreOperation for update and rollback (since you can modify record and it rolls back on error), PostOperation to add student to class (after main op, good spot for side effects). Pretty sure that's how Power Platform plug-in stages work, but open if anyone disagrees.
