Quick Answer
The answer is the “When a user is added to a group” trigger. This trigger is the correct choice because it specifically monitors Microsoft Entra ID for new members being assigned to a security or Microsoft 365 group, making it ideal for sending a welcome email immediately after a user is provisioned. On the Microsoft Power Platform Fundamentals PL-900 exam, this question tests your ability to distinguish between Entra ID triggers and Office 365 triggers, with a common trap being the “When a new user is added to Office 365” trigger—that one only works for users created directly in the Office 365 admin center, not for Entra ID users. Another trap is the premium “When a user is modified” trigger, which fires on profile updates, not new additions. For the exam, remember the memory tip: “Group addition equals new user welcome; Office 365 is for cloud-only, not Entra ID.”
