Salesforce Platform Developer II Sample Questions:

Question #1
A developer is writing code that requires making callouts to an external web service. Which scenario necessitates that the callout be made in an asynchronous method?

A. The callouts will be made using the REST API.
B. The callout could take longer than 60 seconds to complete.
C. The callouts will be made in an Apex trigger.
D. Over 10 callouts will be made in a single transaction.

Question #2
Business rules require a Contact to always be created when a new Account is created. What can be used when developing a custom screen to ensure an Account is not created if the creation of the Contact fails?

A. Use a Database Savepoint method with a try-catch block.
B. Use setSavePoint() and rollback() with a try-catch block.
C. Use the Database.Insert method with allOrNone set to false.
D. Use the Database.Delete method if the Contact insertion fails.

Question #3
An Apex trigger and Apex class increment a counter, `Edit_Count__c`, any time the Case is changed.
```java
public class CaseTriggerHandler {
public static void handle(List<Case> cases) {
for (Case c : cases) {
c.Edit_Count__c = c.Edit_Count__c + 1;
}
}
}
trigger on Case(before update) {
CaseTriggerHandler.handle(Trigger.new);
}
```
A new before-save record-triggered flow on the Case object was just created in production for when a Case is created or updated. Since the process was added, there are reports that `Edit_Count__c` is being incremented more than once for Case edits. Which Apex code fixes this problem?

A. ```java
public class CaseTriggerHandler {
public static Boolean firstRun = true;
public static void handle(List<Case> cases) {
for (Case c : cases) {
B. ```java
trigger on Case(before update) {
Boolean firstRun = true;
if (firstRun) {
CaseTriggerHandler.handle(Trigger.newMap);
}
firstRun = false;
}
```
C. ```java
public class CaseTriggerHandler {
public static Boolean firstRun = true;
public static void handle(List<Case> cases) {
for (Case c : cases) {
D. ```java
public class CaseTriggerHandler {
Boolean firstRun = true;
public static void handle(List<Case> cases) {
if (firstRun) {
for (Case c : cases) {
E. Edit_Count__c = c.Edit_Count__c + 1;
}
}
}
trigger on Case(before update) {
CaseTriggerHandler.firstRun = true;
if (CaseTriggerHandler.firstRun) {
CaseTriggerHandler.handle(Trigger.newMap);
}
CaseTriggerHandler.firstRun = false;
}
```
F. Edit_Count__c = c.Edit_Count__c + 1;
}
}
firstRun = false;
}
}
trigger on Case(before update) {
CaseTriggerHandler.handle(Trigger.new);
}
```
G. Edit_Count__c = c.Edit_Count__c + 1;
}
}
}
trigger on Case(before update) {
if (CaseTriggerHandler.firstRun) {
CaseTriggerHandler.handle(Trigger.new);
}
CaseTriggerHandler.firstRun = false;
}
```

Question #4
Given the following containment hierarchy:
HTML
<template>
<c-my-child-components></c-my-child-components>
</template>
What is the correct way to communicate the new value of a property named "passthrough" to my-parent- component if the property is defined within my-child-component?

A. let cEvent = new CustomEvent('passthrough'); this.dispatchEvent(cEvent);
B. let cEvent = new CustomEvent($passthrough); this.dispatchEvent(cEvent);
C. let cEvent = new CustomEvent('passthrough', { detail: 'this.passthrough' }); this.dispatchEvent(cEvent);
D. let cEvent = new CustomEvent('passthrough', { detail: this.passthrough }); this.dispatchEvent(cEvent);
