Salesforce Platform Developer II Sample Questions (Q116-Q121):

NEW QUESTION # 116
An org has an existing process, built using Process Builder, on Opportunity that sets a custom field, CommissionBaseAmount__c, when an Opportunity is edited and the Opportunity's Amount changes.
A developer recently deployed an Opportunity before update trigger that uses the CommissionBaseAmount__c and complex logic to calculate a value for a custom field, CommissionAmount__c, when an Opportunity stage changes to Closed/Won.
Users report that when they change the Opportunity to Closed/Won and also change the Amount during the same save, the CommissionAmount__c is incorrect.
Which action should the developer take to correct this problem?

A. Call the trigger from the process.
B. Call the process from the trigger.
C. A Replace the process with a Fast Field Update record-trigger flow.

Answer: C

Explanation:
The issue described is likely due to the order of execution in Salesforce, where processes in Process Builder run after all before triggers. If the Opportunity's Amount is changed and the CommissionBaseAmount__c is set by Process Builder, the trigger that calculates CommissionAmount__c may not see the updated value if it operates before the process.
Replacing the process with a before-save record-triggered flow (formerly known as Fast Field Update) would ensure that CommissionBaseAmount__c is updated before the trigger runs. In a before-save flow, field updates occur before any Apex before update triggers fire, which means the trigger would have the updated value of CommissionBaseAmount__c to use in its calculation.

NEW QUESTION # 118
Consider the Apex controller below, that is called from an Aura component.

What is wrong with this code?

A. Line 1: class must be global
8. Lines 1 and 6: class and method must be global
B. Line 8: method must first serialize the list to JSON before returning
C. Line 6: method must be static

Answer: B

Explanation:
The method defined in the Apex class must be static to be used as an Aura-enabled method. Aura-enabled methods need to be static because they are called by the Lightning framework without instantiating the class.References: Apex Developer Guide - Exposing Apex Methods to Lightning

NEW QUESTION # 119
A company manages information about their product offerings in custom objects named Catalog and Catalog Item. Catalog Item has a master-detail field to Catalog, and each Catalog may have as many as 100,000 Catalog Items.
Both custom objects have a CurrencylsoCode text field that contains the currency code they should use. If a Catalog's CurrencylsoCode changes, all of its Catalog Items' CurrencylsoCodes should be changed as well.
What should a developer use to update the CurrencylsoCodes on the Catalog Items when the Catalog's CurrencylsoCode changes?

A. A Database. schedulable and Dazabase.Bazchacle class that queries the Catalog object and updates the Catalog Items if the Catalog CurrencylSoCode is different
B. A Database.Schedulable and Database.Batchacle class that queries the Catalog Item object and updates the Catalog Items if the Catalog CurrencylSoCode is different
C. An after insert trigger on Catalog Item that updates the Catalog Items if the Catalog's CurrencylsoCode is different
D. An after insert trigger on Catalog that updates the Catalog Items if the Catalogs CurrencylsoCode is different

Answer: B

Explanation:
Use Database.Batchable for handling large data sets. It can efficiently process 100,000 Catalog Items asynchronously and update CurrencylsoCodes.References: Using Batch Apex

NEW QUESTION # 120
A developer is inserting, updating, and deleting multiple lists of records in a single transaction and wants to ensure that any error prevents all execution.
How should the developer implement error exception handling in their code to handle this?

A. Use Database methods to obtain lists of Database.SaveResults.
B. Use Database.setSavepoint {} and Database.rollBack with a try-catch statement.
C. Use a try-catch statement and handle DML cleanup in the catch statement,
D. Use a try-catch and use sObject.addError() on any failures.

Answer: B

Explanation:
Using Database.setSavepoint() and Database.rollback() within a try-catch statement is the recommended approach for handling transactions that involve multiple DML operations. This allows the developer to roll back all changes if an error occurs, ensuring that partial changes are not committed to the database.
