                                      The Account object has a field, Audit_Code_c, that is used to specify what type of auditing the Account needs and a Lookup to User, zudizar_c, that is the assigned auditor. When an Account is initially created, the user specifies the Audit_Code c. Each User in the org has a unique text field, Audit_Code _e, that is used to automatically assign the correct user to the Account's Auditor_c field.

                                      Question #2

                                      A business requires that every parent record must have a child record. A developer writes an Apex method with two DML statements to insert a parent record and a child record.
                                      A validation rule blocks child records from being created. The method uses a try/catch block to handle the DML exception.
                                      What should the developer do to ensure the parent always has a child record?

                                      • A. Use addExror() on the parent record if an error occurs on the child record.
                                      • B. Set a database savepoint to rollback if there are errors.
                                      • C. Use Catabase.inserc() and set the all = parameter to true,
                                      • D. Delete the parent record in the catch statement when an error occurs on the child record DML operation.
                                      Answer: B

                                      Consider the controller code below that is called from an Aura component and returns data wrapped in a class.

                                      The developer verified that the queries return a single record each and there is error handling in the Aura component, but the component is not getting anything back when calling the controller getSemeData. 'What is wrong?

                                      • A. The member's Name and option should not be declared public.
                                      • B. The member's Name and option should not have getter and setter.
                                      • C. The member's Kame and option of the class MyDataWrapper should be annotated with @AuraEnabled also.
