Salesforce Platform Developer I (PDI) Sample Questions (Q71-Q76):

NEW QUESTION # 71
A developer has an integer variable called maxAttempts. The developer needs to ensure that once maxAttempts is initialized, it preserves its value for the length of the Apex transaction; while being able to share the variable's state between trigger executions.
How should the developer declare maxAttempts to meet these requirements?

Answer: C

Explanation:
To preserve the value of maxAttempts for the length of the Apex transaction and share its state between trigger executions:
* Static Variable:
* Static variables are initialized once per transaction and retain their value throughout the transaction.
* They can be accessed without instantiating the class.
* Private Scope:
* Declaring it as private ensures encapsulation and prevents unintended external modification.
* Helper Class:
* Using a helper class ensures the separation of concerns, keeping trigger logic clean and adhering to best practices.
Example Code:public class HelperClass {
private static Integer maxAttempts = 5; // Default value
public static Integer getMaxAttempts() {
return maxAttempts;
}
public static void setMaxAttempts(Integer attempts) {
maxAttempts = attempts;
}
}
* A: Constants (static + final) cannot be modified after initialization.
* B: Trigger member variables cannot retain values across executions within the same transaction.
* C: Declaring it as a non-static variable in a helper class would reset its value during each trigger execution.
Why Not the Other Options?


NEW QUESTION # 72
Which two characteristics are true for Lightning Web Component custom events? Choose 2 answers

Answer: C,D

Explanation:
In Lightning Web Components (LWC), custom events are used for communication between components. The two characteristics that are true for LWC custom events are:
Option A: Data may be passed in the payload of a custom event using a property called detail.
// Child component JavaScript
const myEvent = new CustomEvent('myevent', {
detail: { data: 'Some data' }
});
this.dispatchEvent(myEvent);
// To enable bubbling and composition
const myEvent = new CustomEvent('myevent', {
bubbles: true,
composed: true
});
this.dispatchEvent(myEvent);
Reference:
"The CustomEvent interface represents events initialized by an application for any purpose. You can pass data to the event handler using the detail property."
- Lightning Web Components Developer Guide: Communicate with Events
Option D: By default, a custom event only propagates to its immediate container.
"Custom events don't bubble or compose by default. To make an event bubble up through the DOM tree, set the bubbles parameter to true when creating the event."
- Lightning Web Components Developer Guide: Event Propagation
Incorrect Options:
Option B: Incorrect because by default, custom events do not propagate to child components or beyond the immediate container without setting bubbles and composed to true.
Option C: Incorrect because @wire is used for data binding and cannot be used to pass data in the payload of a custom event.
