Exam Certified Advanced Administrator topic 1 question 193 discussion

A. Permission Set and C. Profiles are the features that the administrator should use to fulfill this request. Explanation: To make the Profit field available to sales reps and hidden from partners, the administrator can create a permission set that grants access to the Profit field on the Opportunity object and assign it to the sales reps. The administrator can then create a profile for the partner consultants that restricts their access to the Profit field on the Opportunity object. By default, profiles control field-level security for standard and custom objects, and permission sets allow additional access to records and data that aren't granted by profiles. Therefore, using a permission set and a profile is the best way to fulfill this request.
