  What is a possible solution?

  A. Rewrite the business logic and test classes with @TestVisible set on the callout.

• Question 134:

  <lightning:layout multipleRows="true"> <lightning:layoutItem size="12">{!v.account.Name} </lightning:layoutItem>

  Which option has the correct component changes to display correctly on desktops and tablets?

  

  A. Option A
  B. Option B

• Question 135:

  A developer is working with existing functionality that tracks how many times a stage has changed for an Opportunity. When the opportunity's stage is changed, a workflow rule is fired to increase the value of a filed by one. The developer wrote an after trigger to create a child record when the field changes from 4 to 5.

  A user changes the stage of an Opportunities and manually sets the count field to 4. The count field updates to 5, but the child record is not created.

  What is the reason this is happening?

  A. After triggers fire before workflow rules.
  B. After triggers are not fired after field updates.
  C. Trigger .new does not change after a field update.
  D. Trigger .old does not contain the updated value of the count field.
  A. After triggers fire before workflow rules.

  ---

  Explanation

  The issue described is rooted in the Salesforce Order of Execution. When a record is saved, Salesforce follows a very specific sequence of events. First, original triggers (before and after) are executed. Only after these triggers have completed does the system evaluate and execute workflow rules.

  In this scenario, the following happens:

  The user saves the Opportunity with the count set to 4.

  The After Trigger fires. At this point, the field value is still 4. Since the trigger logic only creates a child record when the value "changes from 4 to 5," and it is currently exactly 4 (not yet 5), the condition is not met.

  Next, the Workflow Rule fires and performs a field update, changing the count from 4 to 5.

  According to the platform rules, a workflow field update causes Before and After Triggers to fire one more time to account for the change. However, in this second execution of the after trigger, Trigger.old now contains the value 4 (from the start of the second execution) and Trigger.new contains 5. While the condition old == 4 and new == 5 is now technically true, many developers fail to realize that the first execution (before the workflow) already bypassed the logic because the workflow hadn't updated the value yet.

  If the trigger was written to look for the exact transition, it might fail during the first pass (where the value is 4) and potentially execute during the second pass. However, if the logic is not specifically handled to account for the re-entrant nature of workflow field updates, or if the "After triggers fire before workflow rules" (Option A) is the primary constraint being tested, it explains why the initial save logic didn't see the "5" until it was too late in the initial trigger context.

• Question 136:

  Which annotation exposes an Apex class as a RESTful neb service?

  A. @RemoteAction
  B. @RestResource
  C. @AuraEnaWed
  D. @HttpInvocabte
  B. @RestResource

• Question 137:

  A custom field Exec_Count__c of type Number is created on the Account object. An Account record with a value of 1 for Exec_Count__c is saved. A workflow field update is defined on the Exec_Count__c field to increment its value every time an Account record is created or updated. The following trigger is defined on the Account:

  trigger ExecOrderTrigger on Account (before insert, before update, after insert, after update) {

  for (Account accountInstance : Trigger.new) {

  if (Trigger.isBefore) { accountInstance.Exec_Count__c += 1;

  } System.debug(accountInstance.Exec_Count__c);

  }

  }

  A. 1, 2, 3, 3
  B. 1, 2, 3, 4
  C. 2, 2, 4, 4
  D. 2, 2, 3, 3
  C. 2, 2, 4, 4

• Question 138:

  What is a benefit of using a WSDL with Apex?

  A. Allows for web services to be tested and achieve code coverage
  B. Allows for classes to be imported into Salesforce
  C. Reduces the number of callouts to third-party web services
  D. Enables the user to not pass a Session ID where it is not necessary
  B. Allows for classes to be imported into Salesforce

• Question 139:

  A developer wrote an Apex class to make several callouts to an external system. If the URLs used in these callouts will change often, which feature should the developer use to minimize changes needed to the Apex class?

  A. Session Id
  B. Connected Apps
  C. Remote Site Settings
  D. Named Credentials
  D. Named Credentials

  ---

  Explanation

  When managing integrations where endpoints (URLs) or authentication details are subject to change, Named Credentials (Option D) provide the most maintainable and secure solution. A Named Credential specifies the URL of a callout endpoint and its required authentication parameters in one definition. By referencing a Named Credential in Apex code (e.g., callout:MyExternalSystem/path), the developer abstracts the literal URL away fro1m the code itself.

  If the URL changes, an administrator can simply update the Named Credential record in the Setup menu without requiring a code deployment or a change to the Apex class. Additionally, Named Credentials automatically handle the callout overhead for Remote Site Settings ; you do not need to maintain a separate entry in Remote Site Settings if a Named Credential is used.

  Connected Apps (Option B) are used to allow external applications to connect into Salesforce, not for making outbound callouts. Session IDs (Option A) are authentication tokens and do not manage endpoint URLs. By utilizing Named Credentials, developers ensure that their integration logic remains decoupled from environment-specific configurations, facilitating smoother transitions between sandboxes and production environments.

• Question 140:

  An org has a requirement that the Shipping Address on the Account must be validated by a third- party web service, before the Account is allowed to be inserted.

  What is the optimal way to meet this requirement?

  A. Make a callout to the web service from a custom Visualforce controller.
  B. Make a callout to the web service from a standard Visualforce controller.
  C. Make a callout to the web service from an after insert trigger.
  D. Make a callout to the web service from a before insert trigger.
  D. Make a callout to the web service from a before insert trigger.
