Salesforce PDI Dumps

Public Method (A):The parent component can call a public method defined in the child component to pass data directly.

Why Quick Actions?

Quick Actions allow developers to create prepopulated forms for creating or updating records.

They are a modern alternative to JavaScript buttons in Lightning Experience.

Why Not Other Options?

A: Validation rules enforce data integrity but do not create records.

B: Apex triggers automate processes but are not used for user-initiated actions.

C: Record-triggered flows execute automatically when records are created or updated, but they do not replace JavaScript buttons for user-initiated actions.

Quick Actions:

References:

A: Formula fields are calculated at runtime based on the formula definition and are not stored in the database.

C: Formula fields can reference fields from related objects, allowing cross-object calculations.

Why not other options?

B: Formulas cannot reference themselves; doing so would result in a circular reference error.

D: If a field used in a formula field is deleted, the formula field will break, and Salesforce will prevent deletion until the formula field is updated.

Formula Fields Documentation

SFDX CLI (A):Salesforce CLI allows the automation of deployment scripts to sandboxes. Using commands like sfdx force:source:deploy, developers can deploy metadata directly from source control.

Correct Apex Method for Enhance Element:

The method invoked by an Enhance element in a Next Best Action strategy must return a value that can be used in decision-making (e.g., discount level).

The method signature must match the required inputs and outputs for the strategy.

Next Best Action Apex Integration:

Before-save Apex Trigger:

This is the best solution because a before-save trigger runs before the record is saved to the database, providing an opportunity to validate or modify the data.

In this case, the Apex trigger can validate the email address using a regular expression or a third-party API call to ensure the email address is valid. If the email is invalid, an error message can be displayed using addError().

Why not the other options?

A. Submit a REST API Callout with a JSON payload:

REST callouts are more complex and generally not recommended for simple validation tasks like email format validation. Additionally, callouts cannot be performed directly in a before-save trigger.

C. Use a custom Lightning Web Component (LWC):

LWCs are primarily for UI interactions and should not be used to enforce data validations that are server-side requirements.

D. Use an Approval Process:

Approval Processes are for managing the approval flow of records, not for real-time validations. They cannot enforce email validation directly.

References:

Apex Triggers Documentation

Trigger Context Variables

The Lightning Out library allows a Lightning Web Component to be embedded in a Visualforce page. This approach is the most suitable to make the LWC accessible in Salesforce Classic.

Option A correctly uses a nested SOQL query to retrieve Contact records along with their related Job_Application__c records, filtering by Account.Industry. This approach is efficient and leverages Salesforce's relationship model.

Option C implements a before insert trigger to prevent the creation of Request__c records when specific conditions exist. It uses the addError method to display an error to users.

Example of correct logic:

trigger RequestTrigger on Request__c (before insert) {

for (Request__c req : Trigger.new) {

if (!RequestLogic.isValid(req)) {

req.addError('Your request cannot be created at this time.');

}

}

}

To make an LWC available for use on a record page:

Target Configuration:

Add lightning__RecordPage in the component's .js-meta.xml file to specify where the component can be used.

Expose the Component:

Set isExposed to true in the .js-meta.xml file to make the component available for use.

Example .js-meta.xml File:

Why Not the Other Options?References:

A: A Flow can guide sales reps through a set of scripted steps and call an Apex action to interact with an external REST endpoint.

B: An Invocable method is used to make an Apex method callable from a Flow. This method can call the REST endpoint and return the data for display.

Why not other options?

C: Future methods are asynchronous and cannot return data to the user in real time.

D: Triggers are used for database events, not for guiding users through scripted processes or making REST calls.

References:

Invocable Methods in Flows

Why Re-Parentable Master-Detail Field?

A master-detail relationship allows Line Items to roll up totals (e.g., calculate total amount) to the Order.

Setting the relationship as re-parentable supports moving Line Items between different Orders.

Why Not Other Options?

B. Lookup field: Does not support roll-up summary fields for calculations.

C and D: Relationships in the opposite direction (Order to Line Item) do not support the required logic.

Master-Detail Relationships:

References:

B: Using partial DML statements (e.g., Database.insert(list, false)) allows only valid records to be committed while identifying invalid ones, avoiding runtime errors.

D: The Database.Savepoint method ensures transactional control by allowing rollback to a specific savepoint if an error occurs.

Why not other options?

A: The @ReadOnly annotation is for read-only operations and would not allow DML operations.

C: The System.Limit class helps monitor limits but does not directly control transaction behavior.

Best Practices for Apex Transactions

When writing test classes, accessing the Standard Price Book is essential for creating OpportunityLineItem records.

The method Test.getStandardPricebookId() is specifically designed to retrieve the Standard Price Book ID in a test class context. This ensures you can work with the price book without requiring @isTest(SeeAllData=true).

Why not other options?

B: @isTest(SeeAllData=true) is not recommended because it violates Salesforce best practices by accessing actual org data.

C: @TestVisible is used for visibility between classes but does not relate to retrieving Standard Price Book.

D: Test.loadData() loads test data from static resources but is unnecessary for accessing the Standard Price Book.

References:

Salesforce Testing Framework

Apex Testing Best Practices

A: Using the order number as an external ID ensures Salesforce can identify and update existing records instead of creating duplicates during updates.

B: Ensuring the order number is unique in the OMS guarantees that there will not be multiple records in Salesforce corresponding to a single order.

Option A: Only one method annotated with @InvocableMethod can exist per class.

Option C: The method must be static.

Option E: The method can be declared as Public or Global for broader accessibility.

Tooling API:

The Tooling API provides programmatic access to manage tests and other metadata in the org.

It can execute test classes or methods remotely.

Developer Console:

The Developer Console is a built-in Salesforce tool to execute Apex tests, debug logs, and more.

Allows developers to execute tests interactively.

B. Metadata API: Used for managing metadata, not for running tests.

C. Bulk API: Used for data operations, not related to testing.

Tooling API Overview:

Testing with Developer Console:

B: Salesforce requires that all Apex code have at least 75% test coverage in production before deployment. This ensures that the system remains reliable.

C: All triggers must have some test coverage as part of the overall 75% requirement for Apex code.

Why not other options?

A: Object visibility settings are not a deployment requirement.

D: Visual Flows do not require test coverage for deployment to production.

Rendering as PDF:

The renderAs="pdf" attribute in the

References:

Using a formula field is the most efficient solution to calculate the ratio between rejected and approved timesheets. It minimizes maintenance overhead by dynamically calculating the value based on the existing roll-up summary fields.

Example Formula:

Total_Rejected_Timesheets__c / Total_Approved_Timesheets__c

B: @testSetup inserts data once and shares it across all test methods in the class, saving system resources.

D: @isTest(SeeAllData=true) is incompatible with @testSetup due to their differing purposes for managing test data.

Unit Test Scenarios:

Option B is valid because getContentAsPDF() can generate PDF content for testing purposes.

Why Not Other Options?

A: Unit tests cannot execute anonymous Apex as a different user.

C: Unit tests cannot perform callouts unless mock responses are provided.

D: The System.createdDate field cannot be set manually in unit tests.

Testing Best Practices:

References:

To override the Edit button in both Salesforce Classic and Lightning Experience:

Use a Visualforce page for Salesforce Classic.

Use a Lightning component for Lightning Experience by configuring the Lightning override.

In Option B, the webservice keyword is used to declare the class and the specific method updateRecords. This is correct because:

The helper method helperMethod is private and not exposed to the external application.

The webservice method updateRecords is declared global static, making it accessible externally.

In Aura components:

B. Renderer: Contains custom rendering logic.

C. Controller: Manages user interaction and component events.

E. Helper: Contains reusable JavaScript functions for logic.

Apex Trigger (Option B):

An Apex trigger can be written on the Container__c object to prevent deletion unless the Status__c field value is "Decommissioned".

This allows custom logic to be executed during the deletion process.

Execution Flow:

The loop runs 500 times (i ranges from 0 to 499).

In each iteration, a new Account record is created and inserted.

Governor Limits:

This code violates the governor limit of 150 DML statements per transaction because each insert is executed individually.

However, the code logically attempts to insert 500 accounts.

Key Consideration:

The code demonstrates inefficient handling of DML operations and would fail in a real-world scenario.

Governor Limits:

References:

The requirement specifies that the Salary__c field should function as a currency input and honor field-level security.

The lightning-input-field component (Option C) automatically respects field-level permissions set in Salesforce and ensures the Salary__c field is editable and viewable only by authorized users.

Other options do not guarantee compliance with field-level security:

Option A: does not enforce field-level security.

Option B: is read-only and cannot be used for editing.

Option D: requires custom logic for enforcing security.

Field-Level Security Best Practices

Why Data Loader?

Data Loader supports all standard and custom objects, including Opportunities.

It is suitable for importing large data volumes like 500 records.

Why Not Data Import Wizard?

The Data Import Wizard does not support all objects, such as Opportunities.

Why Not Other Options?

A: Data Loader does not automatically relate Opportunities to Accounts unless provided external IDs.

B: Data Loader is a desktop application, not browser-based.

D: The Data Import Wizard can handle more than 500 records for supported objects, but it doesn't support Opportunities.

Data Loader Documentation:

References:

Why Salesforce CLI?

The Salesforce CLI supports scripting for Continuous Integration (CI) pipelines, allowing automatic testing and deployment as part of the CI process.

Why Not Other Options?

B: Visual Studio Code is a development IDE, not a CI tool.

C: Force.com Toolkit is outdated and does not support CI processes.

D: Developer Console is for debugging and manual testing, not automation.

Salesforce CLI Documentation:

References:

sObject: SOQL queries can return single or multiple records as sObject instances.

List: SOQL queries often return results as a List of sObject.

Double: SOQL aggregate queries can return numeric data types like Double (e.g., COUNT, SUM).

Record-triggered flows allow automation to create tasks when an Opportunity is created. It is declarative, easy to maintain, and does not require custom code.

Steps:

Create a record-triggered flow for the Opportunity object.

Set it to run on record creation.

Use the "Create Records" element to create a task for the Opportunity owner.

Option A: A screen-based flow is ideal for gathering multiple pieces of information from the user interactively. It provides a declarative way to guide the service agent through the process step-by-step.

Not Suitable:

Option B: An approval process is for routing records for approval, not for gathering user input.

Option C: Apex triggers are for automation, not for interactive user input.

Option D: A Lightning Component could work but requires custom development, which is less efficient than using flows.

To embed a Flow in an Aura component, the lightning:flow tag is used. It allows developers to interact with flows declaratively in Aura components.

A before trigger fires when records are inserted, updated, or deleted. Using the Data Loader or Bulk API to import data updates records, which triggers the before insert or before update events.

Not Suitable:

Option A: Renaming or replacing picklists does not trigger a record-level operation.

Option B: The Mass Address Update tool is not a record operation that triggers before triggers.

Option D: Converting leads to contacts triggers lead conversion events, not directly related to Account triggers.

Option B: The component renders all messages added to the ApexPages messages collection on a Visualforce page, including those added by the ApexPages.addMessage() method.

Not Suitable:

Option A: is for specific fields, not for the general messages collection.

Option C: is used for displaying a single, static message, not the dynamic collection of messages.

Option D: does not display messages.

To use an Apex interface within a class, the class must implement the interface using the implements keyword. This is the correct way to inherit behavior defined in an interface.

Example:

public class SilverLaptop implements Laptop {

// Implementation of the methods defined in the Laptop interface

}

Why not other options?

B: The extends keyword is used for inheriting from a class, not implementing an interface.

C: This syntax is incorrect and not supported in Apex.

D: This syntax is also incorrect as interfaces are not referenced with an @Interface annotation in Apex.

References:

Apex Interfaces Documentation

Master-detail relationships allow roll-up summary fields to aggregate data from child records. If a roll-up summary field exists on the Account object, the relationship cannot be changed to a lookup because lookup relationships do not support roll-up fields.

Why not other options?

A: Null values in the Vendor records do not prevent the change.

C: Custom fields can have their types changed as long as dependencies like roll-up fields are not present.

D: Organization-wide defaults do not affect the ability to change relationships.

References:

Salesforce Master-Detail Relationships and Roll-Up Summary Fields

Why Use Static Resources and Test.loadData?

C: Static resources allow you to define reusable test data (e.g., in a CSV file).

D: Test.loadData simplifies loading bulk test data into test classes from static resources.

Why Not Other Options?

A: Using @isTest(seeAllData=true) violates test isolation principles and is discouraged.

B: @isTest(isParallel=true) is used for parallel execution, not for creating test data.

Test.loadData:

References:

An Apex REST class can be used to retrieve real-time data from an external order management system. The flow can then call the REST class to display the retrieved data on the screen dynamically.

To meet the requirements:

For mobile devices, the content should display in three rows.

For desktops and tablets, the content should display in a single row.

Explanation of Correct Option (B):The code uses lightning:layoutItem with appropriate sizing for mediumDeviceSize="4", which ensures:

Mobile devices: Each layout item will occupy the full width (size="12"), resulting in three rows.

Tablets and desktops: Each layout item will occupy one-third of the row (mediumDeviceSize="4"), displaying in a single row.

Example Code from Option B:

{!v.account.Name}

{!v.account.AccountNumber}

{!v.account.Industry}

Option A: Does not account for mediumDeviceSize and will not adjust for tablets/desktops.

Option C: Uses incorrect sizing for mediumDeviceSize, which may not display correctly for tablets/desktops.

The provided code attempts to update all Lead records in an environment with more than 2,000 records. This will likely exceed the governor limit for the total number of records processed in DML statements, which is 10,000 per transaction. To avoid this, the developer can use Database.update with batching logic.

The Data Import Wizard allows importing data while adhering to Salesforce's sharing and security model. By setting field-level security, sensitive fields can be hidden from unauthorized users.

Other Options:

Option A: Encrypting data externally is unnecessary since Salesforce has built-in security features.

Option B: Using the Data Loader with Apex adds unnecessary complexity.

Option D: The Salesforce CLI does not provide direct data import capabilities with security settings.

Validation Rule Violations:

Salesforce automatically throws exceptions for validation rule violations during DML operations.

References:

Option C: Roll-up summary fields can cause triggers to fire again as they recalculate parent records.

Option D: After-save record-triggered flows can update records, which may fire triggers on those records.

Apex Jobs Page:

Provides a user-friendly interface to view the status and details of enqueued jobs, including those implementing the Queueable interface.

AsyncApexJob Object:

The AsyncApexJob object stores information about queued Apex jobs.

Developers can query this object for job details like Status, JobType, etc.

Example SOQL Query:SELECT Id, Status, JobType, CreatedDate

FROM AsyncApexJob

WHERE JobType = 'Queueable'

Why Not Other Options?

A. Apex Status page: Not a relevant Salesforce feature.

D. Apex Flex Queue: Only applicable to Batch Apex jobs, not Queueable jobs.

AsyncApexJob:

References:

The variable isOK is declared but not initialized, so its value is null. The if-else conditions check for specific values of isOK (true or false), but since it is null, none of those conditions are satisfied. The program defaults to the else block, assigning 4 to x.

Best practices in Apex development for triggers and service layers include:

Avoiding DML operations and queries in loops.

Handling bulk processing efficiently.

Option A ensures compliance by performing all updates at the end, reducing the risk of hitting governor limits.

Scratch orgs are created using the Salesforce CLI (sfdx force:org:create) as part of Salesforce DX. It is specifically designed for development and testing purposes.

Why not other options?

B: Sandbox refresh is used for creating sandboxes, not scratch orgs.

C: Developer Console is used for debugging and code development but cannot create scratch orgs.

D: Workbench is a tool for API testing and data manipulation, not for scratch org creation.

References:

Salesforce CLI and Scratch Orgs

When working with a Lightning Web Component (LWC), the correct syntax for importing an Apex method is:import methodName from "@salesforce/apex/ControllerName.methodName";.

Why not other options?

A, B, and C: These use incorrect syntax for importing Apex methods in LWCs.

References:

Lightning Web Components Documentation

Option A: The fire() method is used to publish Aura application events in the traditional publish-subscribe model.

Not Suitable:

Option B: sendEvent() is not a valid method for Aura events.

Option C: FireEvent() does not exist.

Option D: emit() is not part of the Aura event framework.

To embed a Lightning component in a Visualforce page, the following are required:

A: is necessary to include the Lightning framework on the Visualforce page.

C: $Lightning.use() initializes the Lightning app and is essential for using Lightning components.

Why not other options?

B: $Lightning.createComponent is used for creating a specific Lightning component but is not enough on its own.

D: includes SLDS (Styling) but is unrelated to embedding Lightning components.

E: This is not a valid syntax.

References:

Embedding Lightning Components in Visualforce

A: Declarative development does not require Apex test classes since it leverages built-in Salesforce features such as flows, process builders, and validation rules.

C: Declarative development can be done using the Setup menu, which includes point-and-click tools like page layouts, workflows, and Lightning App Builder.

Why not other options?

B: Declarative development has strict limits (e.g., process builders and flows have governor limits that are lower than programmatic approaches like Apex).

D: Declarative logic still requires maintenance, especially as business needs evolve.

References:

Declarative vs Programmatic Development

The Boolean isOK variable is declared but not initialized, meaning its value is null by default in Apex.

The code evaluates the if-else conditions in sequence:

Condition 1: isOK == false && theString == 'Hello'

isOK is null, so this evaluates to false.

Condition 2: isOK == true && theString == 'Hello'

Again, isOK is null, so this evaluates to false.

Condition 3: isOK != null && theString == 'Hello'

isOK is null, so isOK != null evaluates to false.

Else block: None of the above conditions are true, so the code enters the else block and sets x = 4.

Apex Boolean Data Type

Salesforce CLI allows developers to automate deployments and run unit tests as part of a continuous integration (CI) pipeline. It is the most efficient tool for scripting these processes.

A try-catch block allows the batch to continue processing even if some records cause errors. Errors can be logged for review, ensuring the integration process does not stop entirely.

A record-triggered flow is the recommended tool for this scenario because it:

Can compare the Contact.MailingState field with the Preferred_Locations__c field on the Job__c record.

Automatically updates or calculates values whenever changes are made, keeping data in sync without requiring Apex code or custom development.

A master-detail relationship from Engineering_Support__c to Opportunity allows multiple child Engineering_Support__c records to be associated with a single parent Opportunity. It also enables roll-up summary fields to aggregate data from the child records onto the parent Opportunity.

Upload the SVG file as a static resource in Salesforce.

Import it in the LWC JavaScript file and define it as a property.

Reference the property in the component’s HTML template.

Example:

import mySvg from '@salesforce/resourceUrl/mySvg';

export default class MyComponent extends LightningElement {

svgUrl = mySvg;

}
