Profiles, permission sets, groups and muting

How to grant object, field and system permissions with the least effort and least privilege: what only a profile can do, why permission sets and permission set groups are the recommended model, how permissions combine, and how a muting permission set removes a permission from one group without touching the others.

Official exam objective
Given a scenario, determine the appropriate use of a custom profile or permission set (using the various profile settings, permission set group, and muting).

What the exam expects

  • Decide whether a requirement belongs on a profile or in a permission set, knowing which settings only profiles hold.
  • Grant a one-off permission to a single user without cloning a profile.
  • Predict a user's effective permissions when a profile and several permission sets grant different levels on the same object.
  • Remove a permission that a profile grants, and explain why a permission set can't do it.
  • Bundle permission sets into permission set groups by job function, and use a muting permission set to withhold one permission from one group.
