Which feature of an entity object would you use to enforce that an attribute value is required?
A.
Select the attribute’s Primary Key attribute setting.
B.
Select the attribute’s Mandatory attribute setting.
C.
Set the attribute’s Updatable attribute setting to Always.
D.
Set the attribute’s Updatable attribute setting to Never.
E.
Enforcing that an attribute value is required is implemented only in a view object.
Explanation:
Make an Attribute Mandatory by selecting the Mandatory checkbox if the field is required. The mandatory
property is enforced during entity-level validation at runtime (and not when the attribute validators are run).
