Exam AB-410 Topic 1 Question 23 Discussion

The business rule should use Set requirement level to make the target column Business Required when the stated condition is true. In a model-driven form, this prevents the record from being saved until a value is entered, and the requirement can be returned to Optional when the condition no longer applies. Show recommendation presents advisory guidance that a user may ignore, so it cannot enforce completion. Set field visibility only controls whether a control is displayed. Set default value supplies an initial value but does not guarantee that a valid value remains or that the user cannot clear it. The rule should be scoped to the intended table or form and should include both the true and false paths so requirement level does not remain incorrectly set after values change. If the rule must govern updates through APIs as well as forms, the designer must confirm that the selected scope and action provide server-side enforcement for the scenario. The Study Guide explicitly lists "configure business rules." Option D is the declarative, no-code action that implements conditional mandatory data entry and blocks the form save until the requirement is satisfied.
