Exam Plat-Admn-202 Topic 4 Question 58 Discussion

The correct answers are B. Set organization-wide default to Private, D. Disable Grant Access Using Hierarchies, and E . Create a criteria-based Sharing Rule for the HR Department.
Set the Review object's OWD to Private so review records are not visible to all employees by default. Organization-wide defaults define the baseline record access users have to records they do not own.
Disable Grant Access Using Hierarchies because this is a custom object and the requirement says only HR and the submitting employee should see the review. Salesforce allows this setting to be disabled for custom objects so managers higher in the role hierarchy do not automatically inherit access.
Create a criteria-based sharing rule for the HR department so HR can see the Review records even though the default access is private. Salesforce sharing rules are used to grant wider access beyond OWD.
Why others are incorrect:
A is not needed and a Master-Detail relationship to User is not the right access-control design.
C is incorrect because removing Review Read permission from non-HR users would also prevent the submitting employee from viewing their own submitted review.
