Which three Visualforce components can be used to initiate Ajax behavior to perform partial page updates?

• A. <apex:commandLink>
• B. <apex:actionStatus>
• C. <apex:form>
• D. <apex:actionSupport>
• E. <apex:commandButton>

Consider the following code snippet:
Java
01 public with sharing class AccountsController{
03 @AuraEnabled
04 public List<Account> getAllAccounts(){
05 return [Select Id, Name, Industry FROM Account];
06 }
08 }
As part of the deployment cycle, a developer creates the following test class:
Java
@isTest
private class AccountsController_Test{
@TestSetup
private static void makeData(){
User user1 = [Select Id FROM User WHERE Profile.Name = 'System Administrator' ... LIMIT 1]; User user2 = [Select Id FROM User WHERE Profile.Name = 'Standard User' ... LIMIT 1]; TestUtils.insertAccounts(10,user1.Id); TestUtils.insertAccounts(20,user2.Id);
}
@isTest
private static void testGetAllAccounts(){
// Query the Standard User into memory
List<Account> result = AccountsController.getAllAccounts();
System.assertEquals(20,result.size());
}
}
When the test class runs, the assertion fails. Which change should the developer implement in the Apex test method to ensure the test method executes successfully?

• A. Query the Standard User into memory and enclose lines 15 and 16 within the System.runAs(user) method.
• B. Query the Administrator user into memory and enclose lines 15 and 16 within the System.runAs(user) method.
• C. Add @IsTest(seeAllData=true) to line 12 and enclose lines 15 and 16 within Test.startTest() and Test.
  stopTest().
• D. Add System.runAs(User) to line 14 and enclose line 15 within Test.startTest() and Test.stopTest().

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

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?4

• A. Cast each object into an sObject and use sObject.get('Name') to compare the Name fields.1112
• B. Invo13ke a Schema.describe() function to compare the14 values of each Name field.
• C. Use the Salesforce Metadata API to extrac8t the value of each object and compare the Name fields.910
• D. Use a String.replace() method to parse the contents of each Name field and then compare the results.567

Which statement is considered a best practice for writing bulk safe Apex triggers?

• A. Perform all DML operations from within a future method.
• B. Add records to collections and perform DML operations against these collections.
• C. Add LIMIT 50000 to every SOQL statement.
• D. Use the Database methods with allOrNone set to false instead of DML statements.
