NEW QUESTION # 120
Consider the controller code below that is called from an Aura component and returns data wrapped in a class.
The developer verified that the queries return a single record each and there is error handling in the Aura component, but the component is not getting anything back when calling the controller getSemeData. 'What is wrong?
Answer: B
Explanation:
For the data to be passed back to the Aura component, all properties of the Apex class that are intended to be accessed from the component need to be annotated with @AuraEnabled. Without this annotation, the Aura framework cannot serialize the properties to send them to the front end.
NEW QUESTION # 121
A developer wants to write a generic Apex method that will compare the Salesforce Name field between any two object records. For example, to compare the Name field of an Account and an Opportunity; or the Name of an Account and a Contact.
Assuming the Name field exists, how should the developer do this?
Answer: D
Explanation:
Casting each object to an sObject and using the get method to compare the Name fields is the correct approach. This is because sObjects are generic object representations that can be used to access the fields of any Salesforce object dynamically. Reference:
sObject Class
NEW QUESTION # 122
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,B
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.

Universal Containers ne=ds to integrate with several external systems. The process Is Initiated when a record Is created in Salesforce, The remote systems do not require Salesforce to wait for a response before continuing.
What is the recommended best solution to accomplish this?
Answer: D
Explanation:
Platform events provide a robust and scalable way to communicate changes and events from Salesforce to external systems, especially when there is no requirement for Salesforce to wait for a response. They are designed to support event-driven architectures and can handle high volumes of events that can be published and consumed by external systems. Outbound messages, on the other hand, are limited by the need for an acknowledgment response from the target system, which can introduce latency.
