Question 19/90

A developer built an Aura component for guests to self-register upon arrival at a front desk kiosk. Now the developer needs to create a component for the utility tray to alert users whenever a guest arrives at the front desk.
What should be used?

A. DML Operation

B. Changelog

C. Application Event

D. Component Event

Correct Answer: C

Application Events in Aura components are used for communication between components that are not in the same containment hierarchy. An application event to alert users about the arrival of a guest at the front desk is appropriate because it allows any component within the app to listen and respond to the event, regardless of where it is located in the component hierarchy.References: Aura Components Developer Guide - Application Event
