NEW QUESTION # 129
A developer created a Lightning web component for the Account record page that displays the five most recently contacted Contacts for an Account. The Apex method, Contacts, returns a list of Contacts and will be wired to a property in the component.
Which two lines must change in the above code to make the Apex method able to be wired?
Choose 2 answers
Answer: A,D
Explanation:
To make an Apex method callable from a Lightning Web Component, you need to annotate the method with
@AuraEnabled and mark it as cacheable if it's only retrieving data without modifying it. Additionally, the method must be public to be accessible from the component.
* Line 04: Needs @AuraEnabled(cacheable=true) to allow the method to be called from the Lightning Web Component and indicate that the method doesn't modify any data, making it suitable for caching.
* Line 09: The method getFiveMostRecent should not be private because private methods cannot be called from a Lightning Web Component. Changing it to public (or default, which is equivalent to public within the same namespace) is required.
