How does the behavior of committing a permission set differ from that of a profile?

The behavior of committing a permission set and a profile is indeed similar, particularly in that both focus on permissions related to user access within Salesforce. When a permission set is committed, it retrieves only the active permissions that have been assigned to users, which allows for a more tailored and efficient management of access rights. This selective retrieval contrasts with the idea that it retrieves all permissions indiscriminately.

Profiles, which serve as a more general set of permissions for users in Salesforce, can encompass broader access settings, including default permissions and those that apply universally across users with that profile. However, when it comes to permission sets, they are designed to extend the capabilities of profiles, enabling administrators to grant specific permissions without modifying the profile itself.

This distinction underscores the flexibility that permission sets offer; while profiles apply to all users assigned to them, permission sets can provide granularity by applying to individual users or groups on an as-needed basis. Thus, in this context, the correct answer highlights that committing a permission set behaves in a way that focuses on active, specific permissions, aligning with the needs of dynamic user roles in Salesforce.
