• Question 351:

  A company uses an external system to manage its custom account territory assignments. Every quarter, millions of Accounts may be updated in Salesforce with new Owners when the territory assignments are completed in the external system.

  What is the optimal way to update the Accounts from the external system?

  A. Apex REST Web Service
  B. Composite REST API
  C. SOAP API
  D. Bulk API
  A. Apex REST Web Service

  Explanation

  When dealing with Large Data Volumes (LDV) --specifically in the range of hundreds of thousands to millions of records--the Bulk API (Option D) is the only optimal choice.

  The Bulk API is based on REST principles but is optimized for processing large sets of data asynchronously. Instead of processing records one by one or in small synchronous chunks (which would hit time limits and consume many API calls), the Bulk API allows you to upload a CSV file or JSON batch. Salesforce then processes these records in the background using parallel processing.

  Options B and C (REST/SOAP) are designed for real-time, synchronous interactions with a limited number of records and would hit rate limits or timeout for millions of records. Option A is for custom logic and is subject to the same synchronous execution limits as standard REST.

• Question 352:

  A developer wrote a trigger on Opportunity that will update a custom Last Sold Date field on the Opportunity's Account whenever an Opportunity is closed. In the test class for the trigger, the assertion to validate the Last Sold Date field fails.

  What might be causing the failed assertion?

  A. The test class has not defined an Account owner when inserting the test data.
  B. The test class has not re-queried the Account record after updating the Opportunity.
  C. The test class has not implemented seeAIIData-truwh the test method.
  D. The test class is not using System.runAs() to run tests as a Salesforce administrator.
  B. The test class has not re-queried the Account record after updating the Opportunity.

• Question 353:

  What is the correct syntax for calling a controller action from a Visualforce page and updating part of the page once the action is completed? (Choose two.)

  B. <apex:actionFunction action="{!Save}" name="Save" rerender="thePageBlock"/>
  C. <apex:commandButton action="{!Save}" value="Save" redraw="thePageBlock"/>
  D. <apex:actionSupport action="{!Save} " event="onchange" rerender="thePageBlock"/>
  B. <apex:actionFunction action="{!Save}" name="Save" rerender="thePageBlock"/>

• Question 355:

  A company has many different unit test methods that create Account records as part of their data setup. A new required field was added to the Account and now all of the unit tests fail.

  What is the optimal way for a developer to fix the issue?

  A. Add the required field to the data setup for all of the unit tests.
  B. Add a before insert trigger on Account to set the value of the required field.
  C. Create a TestDataFactory class that serves as the single place to create Accounts for unit tests and set the required field there.
  D. Change the required field to be a validation rule that excludes the System Administrator profile.
  C. Create a TestDataFactory class that serves as the single place to create Accounts for unit tests and set the required field there.

• Question 356:

  A developer is asked to update data in an org based on new business rules. The new rules state that Accounts with the type set to 'Customer' should have a status of 'Active,' and Accounts with the type set to 'Prospect' should have a status of 'Pending.' No other changes to data should be made.

  D. Security token
  B. Session ID

• Question 358:

  As part of their quoting and ordering process, a company needs to send PDFs to their document storage system's REST endpoint that supports OAuth 2.0. Each Salesforce user must be individually authenticated with the document storage system to send the PDF.

  A. Named Credential with an OAuth Authentication Provider
  B. Hierarchy Custom Setting with a password custom field
  C. Named Credential with Password Authentication
  D. Hierarchy Custom Setting with an OAuth token custom field
  A. Named Credential with an OAuth Authentication Provider

• Question 359:

  Which technique can run custom logic when an Aura Component is loaded?

  A. Use an aura:handler "init" event to call a function.
  B. Use the connectedCallback() method.
  C. Use the standard doInit function in the controller.
  D. Call $A.enqueueAction passing in the method to call.
  A. Use an aura:handler "init" event to call a function.

• Question 360:

  Which code snippet represents the optimal Apex trigger logic for assigning a Lead's Region based on its PostalCode, using a custom Region__c object?

  A. Set<String> zips = new Set<String>();for (Lead l : Trigger.new) {if (l.PostalCode != null) {zips.add(l.PostalCode);}}List<Region__c> regions = [SELECT Zip_Code__c, Region_Name__cFROM Region__cWHERE Zip_Code__c IN :zips];Map<String, String> zipMap = new Map<String, String>();for (Region__c r : regions) {zipMap.put(r.Zip_Code__c, r.Region_Name__c);}for (Lead l : Trigger.new) {if (l.PostalCode != null) {Region__c = zipMap.get(l.PostalCode);}}
  B. Set<String> zips = new Set<String>();for (Lead l : Trigger.new) {if (l.PostalCode != null) {zips.add(l.PostalCode);}}for (Lead l : Trigger.new) {List<Region__c> regions = [SELECT Zip_Code__c, Region_Name__cFROM Region__cWHERE Zip_Code__c IN :zips];for (Region__c r : regions) {if (l.PostalCode == r.Zip_Code__c) {Region__c = r.Region_Name__c;}}
  C. for (Lead l : Trigger.new) {Region__c reg = [SELECT Region_Name__cFROM Region__cWHERE Zip_Code__c = :l.PostalCode];Region__c = reg.Region_Name__c;}
  D. Set<String> zips = new Set<String>();for (Lead l : Trigger.new) {if (l.PostalCode != null) {zips.add(l.PostalCode);}}for (Lead l : Trigger.new) {List<Region__c> regions = [SELECT Zip_Code__c, Region_Name__cFROM Region__cWHERE Zip_Code__c IN :zips];for (Region__c r : regions) {if (l.PostalCode == r.Zip_Code__c) {Region__c = r.Region_Name__c;}}}

  Explanation

  The optimal Apex trigger logic is defined by its bulkification and strict adherence to Salesforce governor limits. In Apex, a trigger can process up to 200 records in a single batch. If a developer places a SOQL query inside a loop, the transaction will fail with a System.LimitException if more than 100 records are processed, as the limit is 100 synchronous SOQL queries.

  Option A follows the industry-standard "bulkify, query, and map" design pattern. It iterates through the input records once to gather all relevant search criteria (ZIP codes) into a Set. It then performs a single SOQL query outside of any loop to fetch all matching Region__c records for the entire batch. The results are organized into a Map<String, String> that provides constant-time lookup performance. Finally, it iterates through the Leads again and assigns the Region using the Map.

  Options B, C, and D are anti-patterns. Option C is the most dangerous because it executes a SOQL query for every single record. Options B and D are slightly better but still inefficient, as they execute a query inside a loop that retrieves data repeatedly. Only Option A ensures the code is efficient, bulk-safe, and remains within governor limits even under heavy data loads.
