My colleague found the question and I was wondering what was the answer
A user leaves, and you notice that the user was the last person in a group. You decide to delete the group as well. Deleting groups can cause error messages to be displayed to your users. Identify the two areas where groups are frequently used, where such unwanted behavior is most likely to occur. (Choose two) ⦁ Permission schemes ⦁ Saved filters ⦁ Email subscriptions ⦁ Issue security levels ⦁ Workflow post functions ⦁ Email notification schemes
