Which trigger executes an action only once when a record exits a state for the first time?

The exit trigger in a state transition context is designed to execute an action when a record transitions out of a specific state for the first time. This trigger is particularly important in workflows where the movement of a record through various states requires specific actions to occur when leaving a particular state, such as sending notifications, updating fields, or initiating processes.

When a record exits a state, the exit trigger allows for a one-time action to occur rather than recurring actions that might happen during subsequent exits. This ensures that the workflow is efficient and only performs necessary actions at the appropriate times, particularly when a record is transitioning to a new state.

The other options do not fit this specific criterion: the entry trigger would act upon entering a state, the transition trigger would execute actions every time a record changes between specified states, and the scheduled trigger relies on timed events rather than state transitions. Therefore, the exit trigger aligns perfectly with the requirement of executing an action just once when a record exits a state for the first time, making it the accurate choice in this context.
