Universal Containers (UC) rollingout a new Customer Identity and Access Management Solution will be built...

 To limit user access to only a subset of service providers per customer type, the identity architect should use Profiles and Permission Sets to assign user access to Admin Pre-Approved Connected Apps. Connected apps are frameworks that enable external applications to integrate with Salesforce using APIs and standard protocols, such as OpenID Connect. By setting each of the Connected App access settings to Admin Pre-Approved, the identity architect can control which users can access which connected apps by assigning profiles or permission sets to the connected apps. The other options are not relevant for this scenario. References: Connected Apps, Manage Connected Apps
