Which two are phases in the Aura application event propagation framework? Choose 2 answers
Correct Answer: A,C
In the Aura framework, application events propagate through the component hierarchy in specific phases. The two main phases are: Option A: Bubble Correct Phase. In the bubble phase, the event propagates upward from the source component to the root component. Components can handle the event during this phase by registering an event handler with phase="bubble". The default phase occurs after the capture and bubble phases. It's used for default processing that occurs unless the event is stopped during the earlier phases. Handlers registered without specifying a phase default to this phase. There is no 'Control' phase in the Aura event propagation framework. Option D: Emit Not a Phase. 'Emit' refers to the action of firing or dispatching an event. It is not a phase in the event propagation process. Conclusion: The two phases in the Aura application event propagation framework are Bubble (Option A) and Default (Option C). Understanding these phases is essential for managing event handling in Aura components. Reference: Event Propagation Phases Option C: Default Correct Phase. Event Propagation Phases Options Not Accurate: Option B: Control Incorrect.
