Salesforce PDII Online Questions & Answers

• Question 191:

  A developer is responsible for formulating the deployment process for a Salesforce project. The project follows a source-driven development approach, and the developer wants to ensure efficient deployment and version control of the metadata changes.

  Which tool or mechanism should be utilized for managing the source- driven deployment process?

  A. Data Loader
  B. Change Sets
  C. Salesforce CLI with Salesforce DX
  D. Unmanaged Packages
  C. Salesforce CLI with Salesforce DX

  ---

  Explanation

  Source-driven development shifts the "source of truth" from the Salesforce Org to a Version Control System (like Git). To bridge the gap between local source code and the Salesforce platform, Salesforce CLI with Salesforce DX (Option C) is the required mechanism.

  Salesforce DX (Developer Experience) introduced a source-centric metadata format that is more granular and easier to track in version control than the traditional Metadata API. The Salesforce CLI provides the command-line tools necessary to automate the deployment process, create scratch orgs for isolated testing, and perform "source tracking" to identify exactly which files have changed. This is the foundation of modern CI/CD (Continuous Integration/Continuous Delivery) pipelines in the Salesforce ecosystem.

  In contrast, Change Sets (Option B) are org-centric and manual, making them incompatible with automated version control. Data Loader (Option A) is for record data, not metadata. Unmanaged Packages (Option D) are used for distribution but do not support the iterative, source-controlled deployment workflow required for professional project management.

• Question 192:

  A company wants to build a custom Aura Component that will display a specified Account Field Set and that can only be added to the Account record page.

  Which design resource configuration should be used?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  B. Option B

• Question 193:

  A developer is tasked with creating an application-centric feature on which end-users can access and update information. This feature must be available in Lightning Experience while working seamlessly in multiple device form factors, such as desktops, phones, and tables. Additionally, the feature must support Addressable URL Tabs and interact with the Salesforce Console APIs.

  What are two approaches a developer can take to build the application and support the business requirements? (Choose two.)

  A. Create the application using Aura Components wrapped in Lightning Web Components.
  B. Create the application using Lightning Web Components wrapped in Aura Components.
  C. Create the application using Aura Components.
  D. Create the application using Lightning Experience Builder.
  B. Create the application using Lightning Web Components wrapped in Aura Components.
  C. Create the application using Aura Components.

• Question 194:

  A developer created an Apex class that updates an Account based on input from a Lightning web component that is used to register an Account. The update to the Account should only be made if it has not already been registered.

  account = [SELECT Id, Is_Registered__c FROM Account WHERE Id = :accountId];

  if (!account.Is_Registered__c) {

  account.Is_Registered__c = true;

  // ...set other account fields...

  update account;

  }

  What should the developer do to ensure that users do not overwrite each other's updates to the same Account if they make updates at the same time?

  A. Include LastModifiedDate in the query to make sure it wasn't recently updated.
  B. Add a try/catch block around the update.
  C. Use upsert instead of update.
  D. Use FOR UPDATE in a SOQL query.
  D. Use FOR UPDATE in a SOQL query.

  ---

  Explanation

  In a multi-user environment, a "Race Condition" occurs when two users query the same record at the same time, see that Is_Registered__c is false, and both proceed to update it. To prevent this, developers must implement Row-Level Locking .

  In Salesforce SOQL, the FOR UPDATE (Option D) keyword is used for this exact purpose. When a query includes FOR UPDATE, the platform places an exclusive lock on the records returned. If a second transaction attempts to query the same records using FOR UPDATE, it will be forced to wait until the first transaction is completed (either committed or rolled back). If the lock isn't released within 10 seconds, the second transaction throws a QueryException.

  By using FOR UPDATE, the first user who executes the query "reserves" the Account. The second user's request will wait, and by the time their query actually executes and retrieves the data, Is_Registered__c will have been updated to true by the first user, thus failing the if (!account.Is_Registered__c) check and preventing a duplicate registration. Option A is a manual "optimistic locking" approach that is less reliable than the platform's native locking mechanism. Options B and C do not address the timing issue of the initial check.

• Question 195:

  As part of a custom development, a developer creates a Lightning Component to show how a particular Opportunity progresses over time. The component must display the date stamp when any of the following fields change:

  Amount, Probability, Stage, or Close Date.

  What is the most efficient way to query such information?

  A. SELECT Amount, CloseDate, StageName, ProbabilityFROM OpportunityHistoryWHERE OpportunityId = :oppId
  B. SELECT NewValue, OldValueFROM OpportunityField_HistoryWHERE Opportunity = :oppIdAND Field IN
  C. SELECT NewValue, OldValueFROM OpportunityFieldHistoryWHERE OpportunityId = :oppIdAND Field IN ('StageName', 'Probability', 'Amount', 'CloseDate')
  D. ('StageName', 'Probability', 'Amount', 'CloseDate')
  E. SELECT Amount, CloseDate, StageName, ProbabilityFROM Opportunity_HistoryWHERE OpportunityId = :oppId
  C. SELECT NewValue, OldValueFROM OpportunityFieldHistoryWHERE OpportunityId = :oppIdAND Field IN ('StageName', 'Probability', 'Amount', 'CloseDate')

• Question 196:

  A company processes Orders within their Salesforce instance. When an Order's status changes to 'Paid' it must notify the company's order management system (OMS). The OMS exposes SOAP web service endpoints to listen for when to retrieve the data from Salesforce.

  What is the optimal method to implement this?

  A. Create an Apex trigger and make a callout to the OMS from the trigger.
  B. Generate the Partner WSDL and use it to make a callout to the OMS.
  C. Create an Outbound Message that contains the session ID and send it to the OMS.
  D. Generate the Enterprise WSDL and use it to make a callout to the OMS.
  D. Generate the Enterprise WSDL and use it to make a callout to the OMS.

• Question 197:

  Which scenario requires a developer to use an Apex callout instead of Outbound Messaging?

  A. The callout needs to be asynchronous.
  B. The callout needs to be invoked from a Workflow Rule.
  C. The Target system uses a REST API.
  D. The Target system uses a SOAP API.
  D. The Target system uses a SOAP API.

• Question 198:

  The following code segment is railed from a Trigger handler class from the Opportunity trigger:

  

  Which two changes should improve this code and make it more efficient? (Choose Two)

  A. Move the DML outside of the for loop.
  B. Move the SOQL to fetch the account record outside of the for loop.
  C. Move business logic inside the Opportunity trigger.
  D. Use Triginstead.old instead of Trigger.new.
  A. Move the DML outside of the for loop.
  B. Move the SOQL to fetch the account record outside of the for loop.

• Question 199:

  A developer created a new trigger that inserts a Task when a new Lead is created. After deploying to production, an outside integration is periodically reporting errors.

  Which change should the developer make to ensure the integration is not affected with minimal impact to business logic?

  A. Use a Try/Catch block after the insert statement.
  B. Remove the Apex Class from the Integration User's Profile.
  C. Deactivate the Trigger before the Integration runs.
  D. Use the Database method with allOrNone set to False.
  A. Use a Try/Catch block after the insert statement.

• Question 200:

  The Salesforce instance at Universal Containers currently integrates with a third-party company to validate mailing addresses via REST services. The third-party address verification system recently changed endpoint URLs for all their services from https://th-address-service.3pc.com to https://plc1-mailservice.3pc.com. Everything else remained the same. The developer updated code to reflect this endpoint change, but the mailing address validation service stopped working after the change.

  What else should be done to complete this web service endpoint change?

  A. Create a new Remote Site for the new endpoint URL.
  B. Use a Custom Setting with the new endpoint instead of hard coding the URL.
  C. Test the callout properly using HttpCalloutMock.
  D. Add web service IP addresses to Trusted IP Ranges in the Network Access security controls settings.
  D. Add web service IP addresses to Trusted IP Ranges in the Network Access security controls settings.
