Free and Premium Salesforce PDI Dumps Questions Answers

The Lightning Component framework provides:

Option A: Prebuilt components that can be reused

Explanation:

The framework includes a library of base components that developers can use to build custom components and applications.

These components can be reused and combined to create complex UIs.

To allow moving existing OrderItem records to a new Order record in a master-detail relationship:

Option B: Select the Allow reparenting option on the master-detail relationship.

Explanation: Enabling "Allow reparenting" on the master-detail field allows child records (OrderItem) to be reparented to a different master record (Order).

Steps:

Go to the master-detail field on OrderItem.

Edit the field and select "Allow reparenting".

When using Lightning Data Service (LDS) in a Lightning Web Component (LWC), it's important to understand how data security is handled.

Option D: Lightning Data Service handles sharing rules and field-level security.

Correct Statement.

Explanation:

Lightning Data Service enforces all the security and sharing rules that are in place in the Salesforce org.

This includes object-level, field-level, and record-level security.

When a component uses LDS to access data, the framework ensures that the user only sees data they have access to.

Benefits:

Simplifies development by abstracting security checks.

Ensures compliance with organizational security policies.

Option A: The Apex governor limits are reset for each iteration of the execute() method.

True.

Explanation:

In Batch Apex, each execution of the execute() method is a separate transaction.

Governor limits are reset at the start of each transaction.

When a Lightning component needs to execute a complex SOQL query that joins two objects, and such queries are not supported directly in Lightning components, the solution is to use an Apex controller method.

Option C: Invoke an Apex class with the method annotated as @AuraEnabled to perform the query.

Correct Approach.

Explanation:

The Lightning component can call an Apex method annotated with @AuraEnabled.

The Apex method can perform the complex SOQL query and return the results to the component.

To ensure that specific data is available in test methods, the developer should create test data within the test context.

Option B: Use Test.loadData() and reference a CSV file in a static resource.

Correct Approach.

Explanation:

Test.loadData() is a method that allows test methods to load test data from a CSV file stored as a static resource.

This method creates the records in the test context, ensuring that the data is available during the test execution.

Using a CSV file makes it easy to define multiple records with specific field values.

Usage Example:

@isTest

private class MyTestClass {

@isTest

static void testMethod() {

List testRecords = (List) Test.loadData(MyObject__c.sObjectType, 'MyTestData');

// Proceed with testing using testRecords

}

}

Where 'MyTestData' is the name of the static resource containing the CSV file.

When deploying Apex code to a production environment, certain requirements must be met regarding test coverage and annotations.

Option B: Apex classes must have at least 75% code coverage org-wide.

Correct Requirement.

Explanation:

Salesforce requires that all Apex classes and triggers have a combined code coverage of at least 75% before deployment to production.

This means that, across all Apex code in the org, at least 75% of the code must be covered by test methods.

In an Aura component, JavaScript functions can be included in the following resources:

Controller (.js file):

Handles events triggered by user interaction or component lifecycle.

Contains action handlers defined in the component's markup.

"A client-side controller contains the handler functions that are called in response to events fired by the component or other components."— Aura Components Developer Guide: Client-Side Controller

Helper (.js file):

Contains reusable functions that can be called from the controller or renderer.

Helps to keep the controller lean by abstracting complex logic.

"A helper JavaScript resource can be added to an Aura component bundle and is used to store helper functions that can be reused in the component's client-side code."— Aura Components Developer Guide: Helper Functions

Renderer (.js file):

Allows for custom rendering behavior.

Contains methods that can override default rendering lifecycle events.

"A renderer component bundle resource allows you to customize the rendering behavior of a component."— Aura Components Developer Guide: Custom Renderers

Why Other Options Are Incorrect:

C. Style:

The .css file in an Aura component is used for styling and cannot contain JavaScript functions.

"An Aura component or application can have a style (CSS) resource to define its styles."— Aura Components Developer Guide: Style

E. Design:

The .design file is used to define metadata values for the component, especially when used in Lightning App Builder or Community Builder.

"A design resource describes the design-time behavior of an Aura component—information that visual tools need to display the component in a page or app."— Aura Components Developer Guide: Design Files

Conclusion: JavaScript functions in an Aura component can be placed in the Controller, Helper, and Renderer resources. Therefore, the correct answers are A, B, and D.

To ensure Pricing_Structure__c records are available when the test class is executed, the developer can use the following approaches:

Option A: Use a Test Data Factory class.

Valid Approach.

Explanation:

A Test Data Factory class is a utility class that creates test data for use in test methods.

It helps in generating consistent test data and promotes reusability.

The factory class can create the necessary Pricing_Structure__c records for testing.

When using the @InvocableMethod annotation in Apex, there are specific considerations to keep in mind:

Option A: Only one method using the @InvocableMethod annotation can be defined per Apex class.

True.

Explanation:

An Apex class can contain only one method annotated with @InvocableMethod.

This ensures that when the class is invoked from a flow or process, there is no ambiguity about which method to execute.

In the provided class:

public class myClass {

public void myMethod() { /* implementation */ }

}

The class myClass is declared without any sharing keyword (with sharing, without sharing, or inherited sharing).

Default Sharing Behavior:

Apex classes without an explicit sharing declaration run in system context, meaning they do not enforce sharing rules.

Option B: Sharing rules will not be enforced for the running user.

Explanation: Since myClass does not specify with sharing, methods within it execute without enforcing sharing rules, allowing access to all data irrespective of the running user's sharing rules.

To efficiently prevent users (except those with the Sales Manager profile) from changing the Opportunity Status to Closed Lost when the lost reason is blank:

Option D: An error condition formula on a validation rule on Opportunity

Validation rules are designed to enforce data integrity by preventing users from saving records that don't meet certain criteria. They are efficient and declarative.

Validation Rule Formula:

AND(

ISPICKVAL(StageName, "Closed Lost"),

ISBLANK(Lost_Reason__c),

$Profile.Name <> "Sales Manager"

)



Option C: Handle low-level events in the event handler and re-fire them as higher-level events.

True.

Explanation:

It's a best practice to encapsulate lower-level events and re-emit them as higher-level, application-specific events to decouple components and simplify event handling.

To add an additional layer of validation for email addresses on Lead records by using automation and possibly an external validation service, the best solution is to use a custom Lightning Web Component (LWC).

Option C: Use a custom Lightning Web Component to make a callout to validate the fields on a third-party system

Real-Time Validation: An LWC can perform client-side validation and make callouts to external systems to validate the email address as the user inputs data.

User Experience: Provides immediate feedback to the user, improving data quality at the point of entry.

Limitations: This solution works when data is entered through the UI using the LWC component.

To enforce that only Container__c records with a status of "Decommissioned" can be deleted, we need to prevent deletion of records unless they meet this criteria.

Possible Approaches:

Option A: Apex Trigger

Correct.

Explanation:

An Apex before delete trigger can be written to check the Status__c field of each record being deleted.

If the status is not "Decommissioned," the trigger can add an error to prevent deletion.

trigger PreventContainerDeletion on Container__c (before delete) {

for (Container__c container : Trigger.old) {

if (container.Status__c != 'Decommissioned') {

container.addError('Only decommissioned containers can be deleted.');

}

}

}

There are several ways to execute tests in a Salesforce org:

Option A: Setup Menu

Valid Method.

Explanation:

Tests can be run from the Salesforce Setup menu under Apex Test Execution.

Allows selecting and running test classes and methods.

Option A: Roll-up summary fields can cause the parent record to go through Save.

True.

When a child record changes, roll-up summary fields on the parent object are recalculated.

This causes the parent record to save, which can trigger triggers on the parent object.

The recommended process for deploying code and configurations from a Sandbox to Production is to use a change set.

Option C: Use a change set to deploy the Apex code and Lightning Components.

Explanation: Change sets are the standard mechanism provided by Salesforce for deploying customizations between connected orgs (e.g., Sandbox to Production). They support deploying Apex classes, Lightning components, and configurations.

To find the current user's default record type for Opportunity, the developer can use the DescribeSObjectResult and RecordTypeInfo classes.

Option A: Use Opportunity.SObjectType.getDescribe().getRecordTypeInfos() to get a list of record types, and iterate through them until isDefaultRecordTypeMapping() is true.

Correct Approach.

Explanation:

// Get describe result for Opportunity

Schema.DescribeSObjectResult oppDescribe = Opportunity.SObjectType.getDescribe();

// Get list of RecordTypeInfo

List recordTypeInfos = oppDescribe.getRecordTypeInfos();

// Iterate through RecordTypeInfo to find the default one

Id defaultRecordTypeId;

for (Schema.RecordTypeInfo rtInfo : recordTypeInfos) {

if (rtInfo.isAvailable() && rtInfo.isDefaultRecordTypeMapping()) {

defaultRecordTypeId = rtInfo.getRecordTypeId();

break;

}

}

To ensure that the Food_Preference__c picklist field has a value every time a record is created or updated, marking the field as Required on the field definition is the optimal solution.

Option C: Mark the field as Required on the field definition

Universal Enforcement: Setting the field as required at the field level ensures that it must have a value regardless of how the record is created or updated (UI, API, data import).

Data Integrity: Prevents records from being saved without a value in the picklist field, maintaining data consistency.

No Additional Code: Achieves the requirement declaratively without the need for Apex code.

Option A: Data Import Wizard does not support Opportunities.

Explanation: The Data Import Wizard supports importing data for certain standard objects (Accounts, Contacts, Leads, Solutions, Campaign Members, and Person Accounts) and custom objects. It does not support importing data into all standard objects like Opportunities.

To override the Account's standard Edit button in Lightning Experience:

Option A: Lightning component

Explanation: In Lightning Experience, you can override standard buttons with Lightning components by implementing the appropriate interface.

Implementation:

The Lightning component must implement lightning:actionOverride interface.

In a before insert trigger:

Trigger.old is null.

There is no existing record in the database to reference.

Why Not Other Options:

Option A: Describes Trigger.new.

Option B: The variable is defined but has a null value.

Option D: Trigger.old is not an empty list; it is null.

References:

Trigger Context Variables:

"In insert triggers, Trigger.old is null because the records are new."— Apex Developer Guide: Trigger Context Variables

To script the deployment and unit test execution as part of continuous integration (CI), developers use tools that can be automated and run from the command line or scripts.

Option D: Salesforce CLI

Correct.

Explanation:

The Salesforce CLI (Command-Line Interface) is a powerful command-line tool that allows developers to interact with Salesforce orgs.

It supports scripting of deployments using commands like sfdx force:source:deploy and running unit tests using sfdx force:apex:test:run.

The CLI can be integrated into CI/CD pipelines to automate deployments and testing.

Option B: Apex Flex Queue.

Monitors batch jobs waiting for execution.

Option C: Apex Jobs.

Shows all asynchronous Apex jobs, including batch and future methods.

Why Not Other Options:

Option A: Developer Console doesn't provide job status.

Option D: Paused Flow Interviews are unrelated to Apex jobs.

References:

Apex Jobs Monitoring:

"The Apex Jobs page displays information about all Apex jobs—batch jobs, future methods, scheduled Apex, and Apex test jobs."— Salesforce Help: Monitor Your Scheduled Jobs

Scenario:

Universal Containers (UC) wants to allow multiple Accounts to share a default pickup address.

They have created a custom object called Global Address.

Requirement:

Create an efficient model to link multiple Accounts to a single Global Address.

Solution:

To associate multiple Accounts with a single Global Address, we need to create a lookup relationship from Account to Global Address.

Option D: Add a lookup field on the Account object to the Global Address object.

Correct Approach.

Explanation:

Adding a Lookup Field on the Account object that references the Global Address object allows multiple Accounts to reference the same Global Address.

This setup models a many-to-one relationship:

Many Accounts can have the same Global Address as their pickup address.

Benefits:

Data Normalization: Reduces data redundancy by storing the address once.

Ease of Maintenance: Updating the Global Address updates it for all associated Accounts.

Understanding the Code:

for (Integer i = 0 ; i < 500; i++) {

Account a = new Account (Name='New Account ' + i);

insert a;

}

What the Code Does:

Loops from i = 0 to i = 499 (total of 500 iterations).

In each iteration:

Creates a new Account record with the name 'New Account ' + i.

Performs an insert DML operation for each account.

Salesforce Governor Limits:

DML Statements Limit:

Maximum of 150 DML statements per Apex transaction.

When a developer is alerted to an issue with a custom Apex trigger causing records to be duplicated, the most appropriate debugging approach is to add System.debug statements to the code.

Option A: Add System.debug statements to the code to track the execution flow and identify the issue

Trace Execution Flow: System.debug statements help log the values of variables and the execution path.

Identify Logic Errors: By examining the debug logs, the developer can pinpoint where the duplication is occurring.

Minimal Impact: Adding debug statements is a minimal code change and does not alter the functionality.

To prevent duplicate Order records from being created when updates come from the OMS:

Option B: Use the order number from the OMS as an external ID.

Explanation: Setting the Order Number as an External ID allows Salesforce to recognize records based on this unique identifier during upsert operations.

Option D: Ensure that the order number in the OMS is unique.

Explanation: Having a unique Order Number in the OMS ensures that each order can be accurately identified and matched in Salesforce.

Why These Actions Prevent Duplicates:

By using upsert with the External ID, the integration can update existing orders instead of creating new ones.

// Example of upsert operation using External ID

upsert orderRecord Order_Number__c;



Option A: An External ID field can be used to reference an ID from another external system.

True.

Explanation:

External IDs are custom fields that have the External ID attribute selected.

They are used to store unique identifiers from external systems, allowing Salesforce to match and integrate data based on external IDs.

The requirement is for service agents to gather many pieces of information when processing damaged or stolen credit cards.

Option A: Screen-based Flow

Correct Answer.

Explanation:

A Screen Flow allows developers to build guided, interactive forms that collect information from users.

Flows can have multiple screens, validation rules, and branching logic.

They can be created declaratively without code, making them efficient to implement.

Benefits:

Efficient Development: No need for code.

User-Friendly: Provides a step-by-step interface.

Maintainable: Easy to update as requirements change.

Option A: Create a Custom Permission for the users.

True.

Explanation:

Custom Permissions can be used to control access to specific functionality.

By assigning the custom permission to a small group of users, the form's availability is restricted.

Universal Containers (UC) wants to calculate the estimated ship date for an Order, which should be the date when all Order Line Items are available. The availability date is stored on each Order Line Item.

Given that the relationship between Order and Order Line Item is Master-Detail, we can leverage Roll-Up Summary Fields to perform calculations on the child records (Order Line Items) and summarize them on the parent record (Order).

Option A: Use a MAX Roll-Up Summary field on the latest availability date fields.

Correct Approach.

Explanation:

Create a Roll-Up Summary Field on the Order object.

Use the MAX function to calculate the latest availability date among all related Order Line Items.

The Roll-Up Summary Field will display the maximum (latest) availability date, which represents the date when all items are available.

This date can be used as the estimated ship date for the Order since the Order can only be shipped when all items are available.

Benefits:

Declarative Solution: No code required.

Real-Time Calculation: Automatically updates when Order Line Items change.

Option A: After-save record-triggered flow

True.

An after-save record-triggered flow can update records after they are saved.

If the flow updates a record that the trigger is listening to, it can cause the trigger to fire again, affecting the number of times it executes.

ISV Package Development:

The ISV is developing a managed package.

They have an Apex class BodyFat with a method calculateBodyFat().

Requirement:

Ensure calculateBodyFat() is accessible by consumers outside the package namespace.

Solution:

To allow methods in a managed package to be accessible outside the package namespace, they must be declared as global.

Option B: Declare the class and method using the global access modifier.

Correct Approach.

Explanation:

Global Classes and Methods:

In managed packages, only classes and methods declared as global are accessible outside the package namespace.

Declaration:

global class BodyFat {

global void calculateBodyFat() {

// method implementation

}

}

Important Notes:

Public classes and methods in managed packages are accessible only within the namespace.

Global is required to expose the functionality to subscribers.

To back up all data and attachments in a Salesforce org, the standard approach is to use the Data Export Service.

Option B: Define a Data Export scheduled

Correct Answer.

Explanation:

The Data Export Service allows administrators to schedule a weekly or monthly export of all data and attachments.

The exported data can be downloaded as a set of CSV files and attachments in zip format.

Since Case and Defect__c have Private organization-wide defaults (OWD), users need explicit access to the parent records to access the child records in a master-detail or junction object relationship.

The Case_Defect__c is a junction object between Case and Defect__c.

Option C: Share the parent Case and Defect__c records.

Correct Answer.

Explanation:

To access a record on a junction object (Case_Defect__c), a user must have access to both parent records.

Sharing both the Case and Defect__c records with the user will grant them access to the Case_Defect__c record.

The requirement is to model a many-to-many relationship between Account and Bug__c:

Each Account (company) can report multiple bugs.

Each Bug__c can be reported by multiple accounts.

To represent a many-to-many relationship in Salesforce, we use a junction object.

Option A: Junction object between Bug__c and Account

Correct Answer.

Explanation:

Create a custom junction object, e.g., AccountBug__c, with two master-detail relationships:

One to Account.

One to Bug__c.

This allows linking accounts and bugs in a many-to-many fashion.

Enables reporting on which companies have reported which bugs.

To update the flow to create a Contact and store the Contact’s ID on the Opportunity:

Option D: Add a new Create Records element.

Explanation: The flow needs to create a new Contact record using the Create Records element. After creating the Contact, you can store the Contact's ID in a variable and then update the Opportunity with the Contact’s ID.

Steps:

Add Create Records Element: Configure it to create a Contact and store the newly created Contact's ID in a variable.

Update Opportunity: Use the existing Update Records element or add a new one to update the Opportunity with the Contact's ID.
