Universal Containers has built a recruiting application with two custom objects, Job Applications
and Reviews that have a master-detail relationship. Users should NOT be allowed to delete review
records after job application records have been approved.
How would a developer meet this requirement?
Change the interviewer’s profile to Read-only for the review object
Use workflow to change the page layout to Read-only
Remove the Delete button from the job application page layout
Use a validation rule in conjunction with a roll-up summary field
