• Question 52:

  A developer needs to allow users to complete a form on an Account record that will create a record for a custom object.

  The form needs to display different fields depending on the user's job role, The functionality should only be available to a small group of users.

  Which three things should the developer do to satisfy these requirements? Choose 3 answers

  A. Create a Dynamic Form.
  B. Create a Custom Permission for the users.
  C. Add a Dynamic Action to the Users' assigned Page Layouts.
  D. Create a Lightning wed component.
  E. Add a Dynamic Action to the Account Record Page.
  B. Create a Custom Permission for the users.
  C. Add a Dynamic Action to the Users' assigned Page Layouts.
  D. Create a Lightning wed component.

  ---

  Explanation

  Custom Permission:

  Ensures that only the small group of users has access to this functionality.

  Dynamic Action:

  Allows displaying different fields depending on the user's role directly on the Account Record Page.

  Why Not A or C:

  Dynamic Forms are not used to create records for custom objects in this context.

  A Lightning Web Component is unnecessary when Dynamic Actions can be used.

• Question 53:

  Universal Containers has developed custom Apex code and Lightning Components in a Sandbox environment. They need to deploy the code and associated configurations to the Production environment.

  What is the recommended process for deploying the code and configurations to Production?

  A. Use the Force.com IDE to deploy the Apex code and Lightning Components.
  B. Use the Ant Migration Tool to deploy the Apex cade and Lightning Components.
  C. Use a change set to deploy the Apex code and Lightning Components.
  D. Use Salesforce CLI to deploy the Apex code and Lightning Components.
  C. Use a change set to deploy the Apex code and Lightning Components.

  ---

  Explanation

  Why Change Sets?

  Change Sets are the recommended and simplest way to deploy metadata, including Apex code and Lightning Components, from Sandbox to Production.

  Why Not Other Options?

  A: The Force.com IDE is deprecated.

  B: The Ant Migration Tool is more suitable for complex deployments but not necessary for standard Sandbox-to-Production migration.

  D: Salesforce CLI is effective for deployment but requires scripting expertise, making Change Sets easier for most users.

• Question 54:

  A developer is migrating a Visualforce page into a Lightning web component.

  The Visualforce page shows information about a single record. The developer decides to use Lightning Data Service to access record data.

  Which security consideration should the developer be aware of?

  A. Lightning Data Service ignores field-level security.
  B. The with sharing keyword must be used to enforce sharing rules.
  C. Lightning Data Service handles sharing rules and field-level security.
  D. The isAccessible () method must be used for field-level access checks.
  C. Lightning Data Service handles sharing rules and field-level security.

  ---

  Explanation

  Why Lightning Data Service?

  Enforces Salesforce's security model, including:

  Sharing rules.

  Field-level security (FLS).

  This eliminates the need for additional manual security checks.

  Why Not Other Options?

  A: Incorrect, LDS enforces FLS.

  B: with sharing applies to Apex, not Lightning Data Service.

  D: isAccessible() is unnecessary for LDS because it already enforces FLS.

• Question 55:

  How does the Lightning Component framework help developers implement solutions faster?

  A. By providing device-awareness for mobile and desktops
  B. By providing an Agile process with default steps
  C. By providing change history and version control
  D. By providing code review standards and processes
  A. By providing device-awareness for mobile and desktops

  ---

  Explanation

  The Lightning Component Framework simplifies development by providing built-in device awareness, enabling components to adapt automatically for different devices such as mobile phones, tablets, and desktops.

• Question 56:

  A developer identifies the following triggers on the Expense _c object:

  1. deleteExpense;

  2. applyDefaultsToExpense;

  3. validateExpenseUpdate;

  The triggers process before delete, before insert, and before update events respectively.

  Which two techniques should the developer implement to ensure trigger best practices are followed? Choose 2 answers

  A. Unity all three triggers In a single trigger on the Expense__c object that Includes all events.
  B. Unify the before insert and before update triggers and use Flow for the delete action.
  C. Create helper classes to execute the appropriate logic when a record is saved.
  D. Maintain all three triggers on the Expense __c object, but move the Apex logic out of the trigger definition.
  A. Unity all three triggers In a single trigger on the Expense__c object that Includes all events.
  C. Create helper classes to execute the appropriate logic when a record is saved.

  ---

  Explanation

  A. Unify all three triggers in a single trigger on the Expense__c object that includes all events:

  Salesforce best practices recommend having only one trigger per object to avoid redundancy and conflicts.

  By combining all the events (before delete, before insert, and before update) into a single trigger, the developer can manage the logic in an organized and maintainable manner.

  This also simplifies debugging and ensures that the trigger logic executes in a predictable order.

  C. Create helper classes to execute the appropriate logic when a record is saved:

  Using helper classes allows for a clean separation of concerns. The trigger becomes a dispatcher that delegates logic to dedicated classes.

  For example, you can create methods like applyDefaultsToExpense(), validateExpenseUpdate(), and deleteExpense() in a helper class and invoke them from the trigger.

  This improves reusability, readability, and testability of the code.

  Why not the other options?

  B. Unify the before insert and before update triggers and use Flow for the delete action:

  While Flow is a powerful tool, it is not ideal for deleting records or replacing Apex trigger functionality, especially when triggers already exist for other events.

  D. Maintain all three triggers on the Expense__c object but move the Apex logic out of the trigger definition:

  Maintaining multiple triggers on the same object can lead to conflicts and execution order issues, even if the logic is moved to helper classes.

• Question 57:

  A software company uses the following objects and relationships:

  1. Case: to handle customer support issues 2. Defect__c: a custom object to represent known issues with the company's software 3. Case Defect__c a junction object between Case and Defect __c to represent that a defect is a cause of a customer issue 4. Case and Defect__c have Private organization-wide defaults.

  What should be done to share a specific Case_Defect__c record with a user?

  A. Share the parent Cast record Defect_c records.
  B. Share the parent Case and Defect__c records
  C. Share the parent Defect__c record.
  D. Share the case_Defect_c record.
  D. Share the case_Defect_c record.

  ---

  Explanation

  Because Case and Defect__c both have Private organization-wide defaults, access to a junction object record is not automatically granted by sharing only one parent. To give a user access to a specific Case_Defect__c record, that junction object record itself must be explicitly shared. Sharing only the parent Case or Defect__c does not guarantee access to the junction record.

• Question 58:

  Universal Containers (UC) wants to lower its shipping cost while making the shipping process more efficient.

  The Distribution Officer advises UC to implement global addresses to allow multiple Accounts to share a default pickup address.

  The developer is tasked to create the supporting object and relationship for this business requirement and uses the Setup Menu to create a custom object called "Global Address".

  Which field should the developer add to create the most efficient model that supports the business need?

  A. Add a master-detail field on the Global Address object to the Account object.
  B. Add a lookup field on the Global Address object to the Account object.
  C. Add a lookup field on the Account object to the Global Address object.
  D. Add a master-detail field on the Account object to the Global Address object.
  C. Add a lookup field on the Account object to the Global Address object.

  ---

  Explanation

  Why Lookup on Account to Global Address?

  An Account can reference a single default Global Address via a lookup field, allowing multiple Accounts to share the same address.

  This is more efficient than the reverse (lookup on Global Address to Account), as Global Address is the parent in this relationship.

  Avoiding Master-Detail:

  Lookup relationships provide flexibility in this use case since Accounts and Global Addresses have independent lifecycles.

  Example:Create a custom lookup field on Account referencing the Global Address object.

• Question 59:

  A developer needs to determine the default record type for the current user when creating a new record in Apex.

  Which approach should be used?

  A. Query the RecordType object directly
  B. Use getDefaultRecordTypeId from Describe information
  C. Hardcode the record type ID
  D. Use a validation rule
  B. Use getDefaultRecordTypeId from Describe information

  ---

  Explanation

  Salesforce provides describe information that allows developers to programmatically determine metadata details, including the default record type for a specific user and object. By calling SObjectType.getDescribe().getRecordTypeInfos() and identifying the record type where isDefaultRecordTypeMapping is true, the developer can reliably retrieve the correct default record type. Hardcoding record type IDs is not recommended because IDs differ between environments. Validation rules do not provide record type information, and querying RecordType directly does not automatically account for user-specific defaults.

• Question 60:

  As part of a data cleanup strategy, AW Computing wants to proactively delete associated opportunity records when the related Account is deleted.

  Which automation tool should be used to meet this business requirement?

  A. Workflow Rules
  B. Scheduled job
  C. Record-Triggered Flow
  D. Process Builder
  C. Record-Triggered Flow
