Which two settings are exclusive to profiles and not available in permission sets?

The correct answer identifies settings that are exclusive to profiles, highlighting that these settings are not available in permission sets. The first important setting here is Login Hours, which are defined at the profile level to restrict user login times. This setting is vital for ensuring security and controlling access to the Salesforce environment during specified hours. Since login hours are a fundamental part of a user's profile configuration and directly related to their access management, they cannot be assigned through permission sets, which are designed to add permissions on top of existing profile settings rather than replace them.

Tab Settings, Page Layout Assignments, and Record Types can be configured within both profiles and permission sets, allowing for more flexibility in assigning access and functionality to users. This flexibility helps organizations customize roles and responsibilities without the need for creating multiple profiles for various access needs. Therefore, the exclusivity of Login Hours to profiles is what makes this choice correct in the context of Salesforce's data sharing and visibility settings.
