Question #2

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