Salesforce Certified Platform Developer II — Question 200

A developer built a Component to be used at the front desk for quests to self-register upon arrival at a kiosk. The developer is now asked to create a Component for the Utility Tray to alert Users whenever a guest has arrived at the front desk.
What should be used?

Answer options

• A. Application Event
• B. DML Operation
• C. Component Event
• D. ChangeLog

Correct answer: A

Explanation

Using an Application Event is the ideal method for notifying Users about guest arrivals since it allows for broadcasting messages to multiple components. DML Operations and Component Events do not specifically serve the purpose of alerting Users in this context, while ChangeLog is used for tracking changes rather than real-time notifications.
