Free and Premium Salesforce PDI Dumps Questions Answers

An External ID field is used to match data in Salesforce with data from external systems (like an on-premise SQL database). It allows for easy upserts and data integration without relying on Salesforce IDs.

Why not other options?

A: External objects are used for real-time integration with external systems but do not address data matching directly.

C: Formula fields are calculated fields and cannot be used for data matching.

D: Lookup fields are used for creating relationships between objects within Salesforce, not for matching external data.

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:

A. 75% Test Coverage: Salesforce mandates that 75% of all Apex code must be covered by tests to be deployable to production.

D. Trigger Coverage: Each Apex trigger must have at least one line of test coverage to ensure it is properly tested.

Flow Builder:

Flow Builder can evaluate record criteria using a Decision element and then send an outbound message using the "Action" element.

Allows automation without Apex.

Approval Process:

Approval Processes can evaluate criteria and trigger outbound messages as one of the associated actions.

Why Not Other Options?

C. Entitlement Process: Focuses on managing entitlements, not triggering outbound messages.

D. Next Best Action: Used for recommendations and guided actions, not for triggering outbound messages.

Developer Sandboxes are ideal for individual developers. They provide the same configuration as production and allow developers to work independently.

Full Sandbox: Used for staging or testing environments, not suitable for individual developer work.

Developer Edition: Not connected to the production org and lacks sandbox functionality.

Partner Developer Edition: Used by ISVs for AppExchange development, not suitable for internal teams.

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

Throwing Exceptions in Apex:

throw new ExceptionType(); creates a new instance and throws it.

A: No argument constructor.

B: Constructor with a custom error message.

Why Not Other Options?

C and D: These create exception instances but do not throw them, which is not valid syntax for firing an exception.

Apex Exception Handling:

References:

After running all tests, the Overall Code Coverage panel in the Developer Console shows the code coverage percentage for each class.

This is the most reliable and optimal way to view code coverage.

Based on the provided code, an exception is likely being thrown if a required field is missing or if there are validation rules that the record does not meet. Salesforce will throw an exception when an attempt to create a record violates constraints.

Why not other options?

B: Salesforce reports errors for failed DML operations unless they are handled in a try-catch block.

C: The record cannot be created successfully if constraints are violated.

D: Debug logs may provide details, but the record creation would fail.

References:

Apex DML Exception Handling

Advantages of Lightning Web Components (LWC):

A. Rich component ecosystem:

LWCs have a modern, rich component library designed for modular and reusable development.

D. Self-contained and reusable units:

LWCs are designed to be modular, reusable, and self-contained, reducing duplication and enhancing maintainability.

Why Not Other Options?

B. Log capturing via Debug Logs Setup page: This is unrelated to LWC and is a debugging feature.

C. Built-in standard and custom set controllers: Relevant to Visualforce, not LWCs.

LWC Documentation:

References:

The code provided processes all Case records in a single transaction. Since it attempts to process over 10,000 records, it exceeds the Salesforce governor limit of 50,000 DML rows per transaction, causing the transaction to fail.

Governor Limits on DML Rows (C):Salesforce enforces a governor limit of 50,000 rows for DML operations per transaction. In this case, if the SELECT query retrieves over 50,000 records, the Database.update call will hit this limit and throw a System.LimitException.

The deployment fails because the Apex trigger has 0% test coverage. Even though the helper class is covered, Salesforce requires at least 1% test coverage for the trigger itself. To resolve this, a test class and methods must specifically invoke the trigger by performing DML operations on the related object.

 Lightning Component Quick Action (C):Using a Lightning component ensures the user can trigger the HTTP REST callout via a button click on the Opportunity detail page. This provides a seamless user interface experience in Lightning Experience.

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

When a roll-up summary field on a parent object (like Account) is updated due to changes in child records (like Branch), the parent record (Account) is implicitly saved again.

This can result in the execution of the trigger on the parent object. Developers must consider this behavior to avoid unintended recursion or infinite loops.

To test Apex code that makes HTTP callouts, Salesforce provides the HTTPCalloutMock interface. Developers create a test class that implements HTTPCalloutMock to define the fake response that will be returned when the callout is executed during the test.

This ensures that tests do not depend on the availability or behavior of the external system.

Why not other options?

B and C: These are not relevant for testing HTTP callouts.

D: There is no concept of extending HTTPCalloutMock. It is implemented, not extended.

References:

Apex Testing for HTTP Callouts

In the provided code snippet, the class myClass does not specify a sharing declaration (with sharing or without sharing). In Salesforce, when a class does not explicitly declare its sharing context, it defaults to without sharing. This means sharing rules are not enforced.

A: An External ID field is designed to store an ID from another external system, which can be used to match Salesforce records with data from an external source during data imports or integrations.

D: External ID fields are automatically indexed, which can significantly improve the performance of SOQL queries when filtering based on the External ID.

Why not other options?

B: External IDs cannot be formula fields. Only text, number, email, and auto-number fields can be set as External IDs.

C: While External IDs are useful for integrations, they do not make external data visible within Salesforce Mobile.

References:

External IDs Overview

Why Test.loadData()?

Simplifies test data creation by loading data from a CSV file stored as a static resource.

Ideal for testing specific field values in bulk.

Why Not Other Options?

A: Querying data from the org violates test isolation principles.

C: Anonymous Apex cannot be used within test classes.

D: JSON files in Documents are not supported by Test.loadData().

Test.loadData():

References:

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.

The @AuraEnabled(cacheable=true) annotation makes an Apex method available to Lightning Web Components and allows it to be wired to a property while enabling client-side caching for improved performance.

To preserve the value of maxAttempts for the length of the Apex transaction and share its state between trigger executions:

Static Variable:

Static variables are initialized once per transaction and retain their value throughout the transaction.

They can be accessed without instantiating the class.

Private Scope:

Declaring it as private ensures encapsulation and prevents unintended external modification.

Helper Class:

Using a helper class ensures the separation of concerns, keeping trigger logic clean and adhering to best practices.

Example Code:public class HelperClass {

private static Integer maxAttempts = 5; // Default value

public static Integer getMaxAttempts() {

return maxAttempts;

}

public static void setMaxAttempts(Integer attempts) {

maxAttempts = attempts;

}

}

A: Constants (static + final) cannot be modified after initialization.

B: Trigger member variables cannot retain values across executions within the same transaction.

C: Declaring it as a non-static variable in a helper class would reset its value during each trigger execution.

Why Not the Other Options?

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.');

}

}

}

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.

Why Lightning Pages?

The Lightning Component framework is designed for building responsive Lightning Pages.

Allows for dynamic and modular development.

Why Not Other Options?

A: Salesforce Classic does not support Lightning Components.

C: JavaScript buttons are replaced by Quick Actions in Lightning Experience.

D: While integrations are possible, the framework is not primarily used for integrations.

Lightning Components Overview:

References:

 Why Queueable?

Queueable Apex allows asynchronous processing, which can handle bulk updates efficiently without hitting governor limits.

The trigger enqueues the Queueable class to process the asset updates.

 Avoiding Limit Failures:

Moving logic to a Queueable class offloads resource-intensive operations to asynchronous processing.

C: The Bulk API is designed for importing or exporting large volumes of data and works efficiently in development environments, but it respects storage limits.

D: Developer and Developer Pro sandboxes have different storage limits. Developer Pro has a larger storage limit compared to a Developer sandbox.

Why not other options?

A: Bulk API does not bypass storage limits.

B: The Data Import Wizard is a web-based tool, not an application installed on your computer.

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.

SOSL:

Designed for full-text searches, making it faster for unstructured or broad text searches across multiple objects.

Ideal for searching multiple fields simultaneously.

SOQL:

Optimized for structured queries where you need more control over filtering and relationships.

Can return up to 50,000 records in a single query, while SOSL returns only 2,000.

C and D are incorrect because SOSL is faster for text searches, not SOQL.

SOQL vs. SOSL:

Why Not Other Options?References:

A: The save() method in the custom controller must be tested to ensure it works as intended and redirects to the correct page.

B: Setting parameters via ApexPages.currentPage().getParameters() is crucial to test scenarios where user input or URL parameters drive logic.

D: Using Test.setCurrentPage(pageRef) is essential for simulating page context in unit tests.

Why not other options?

C: This statement does not belong to testing a custom controller.

B (second occurrence): It appears to be incorrectly formatted in the question.

The quickest way to make Visualforce pages styled like Lightning Experience is by incorporating SLDS. This provides consistent styling without rewriting the applications.

Why not other options?

A: Rewriting all Visualforce pages as Lightning components is time-consuming and not efficient.

B: There is no attribute enableLightning in Visualforce.

C: Enabling Lightning Experience compatibility does not apply styling automatically.

References:

Salesforce Lightning Design System (SLDS)

For declarative development:

A. Record-Triggered Flow: Allows building complex logic declaratively without code.

D. Validation Rules: Enforce data quality by validating record fields before saving.

Why Validation Rule?

Validation rules are efficient for enforcing field-level conditions without requiring Apex or Flow.

A formula can check if the user’s profile is not "Sales Manager" and if the Lost Reason field is blank when Status is set to "Closed Lost".

Why Not Other Options?

A: Triggers are more complex and unnecessary for this simple validation.

C: Record-triggered flows are less efficient for field validations compared to validation rules.

D: Approval processes do not handle this type of field-level restriction.

Validation Rule Documentation:

References:

@InvocableMethod Requirements:

Must be declared as public static.

Must accept and return a List to support batch operations.

Return type should be compatible with Flow Builder, in this case, a List.

Why Option C?

Fulfills all @InvocableMethod requirements:

@InvocableMethod(label='Additional Info')

public static List getInfo(List contactIds) {

// Implementation

}

Why Not Other Options?

A, B, D: Do not adhere to the public static requirement or fail to use a List as input/output.

InvocableMethod Documentation:

References:

Lightning Web Components (LWCs) are the best choice for creating custom UI components in Salesforce. They provide robust features such as event handling and server-side communication, allowing for validation of user input before saving data.

Option B: Reusing event logic in the helper ensures cleaner and reusable code.

Option D: Handling low-level events in handlers and re-firing them as higher-level events allows for better abstraction and modularity.

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:

Database.insert(records, false):

The Database.insert() method with the allOrNone parameter set to false allows for partial success.

If some records in the list fail due to validation rules, triggers, or other errors, the method will still attempt to insert the remaining valid records.

The false parameter ensures that records that fail will not roll back the transaction for the others.

Why not the other options?

A. Database.insert(records, true):

The true parameter makes the operation transactional (all or none). If any record fails, all records will roll back.

B. insert records:

The insert DML statement behaves like Database.insert(records, true) by default and rolls back all records if any error occurs.

C. insert(records, false):

This syntax is invalid in Apex.

References:

Apex DML Operations Documentation

Database Methods

Performing queries inside a loop can lead to governor limit exceptions due to too many SOQL queries in a single transaction. Instead, perform queries outside loops.

In Visualforce, to specify a standard controller for a custom object, the syntax is controller="ObjectName__c".

To add custom functionality, you can use an extensions attribute to include a controller extension.

Why not other options?

A: The correct syntax is controller, not standardController, for custom objects.

B and C: These are syntactically incorrect.

References:

Visualforce Pages Documentation

Declaring the constant as static ensures it is shared across all instances of the class.

Declaring it as final ensures its value cannot be modified after initialization.

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.

When troubleshooting batch Apex jobs:

Asynchronous Job Monitoring:

Navigate to Setup > Apex Jobs to view the status of the batch job.

Provides information such as success, errors, and total execution time.

This step is crucial to diagnose whether the issue is with system limits, batch size, or specific records.

Debug Logs:

After identifying the issue in the job monitoring page, use debug logs to pinpoint specific errors or bottlenecks.

B. Check the debug logs for the batch job: Debug logs are a secondary step after checking the job status.

C. Disable and recreate with fewer records: Premature without investigating the root cause.

D. Decrease the batch size: Adjusting batch size is a solution but only after identifying the cause of the timeout.

Asynchronous Job Monitoring: &type=1

Debugging Apex:

Why Not the Other Options?References:

Why @TestSetup?

The @TestSetup annotation creates a baseline set of test data once per test class.

Test methods reuse this data, avoiding the need to recreate it repeatedly, which improves efficiency.

Why Not Other Options?

A: HttpCalloutMock is used for mocking callouts, not for creating test data.

C: Using seeAllData=true is discouraged because it relies on org data, violating test isolation principles.

D: While creating data in Test.startTest() works, it is less efficient than @TestSetup for shared data.

Test Setup Methods:

References:

 Option B: Custom events in LWC allow data to be passed using the detail property of the CustomEvent object. This is the recommended way to pass data in a custom event.

To notify the parent component when the child component’s Next button is clicked, the child component can dispatch a custom event. The parent component listens to this event and handles navigation accordingly.

Interfaces in Java and Salesforce Apex:

In Java or Apex, interfaces define a contract that classes must fulfill. They provide method signatures that any implementing class must define.

The keyword implements is used to implement an interface.

Classes and Inheritance:

A class in Java/Apex cannot use extends to inherit from an interface. The extends keyword is reserved for inheriting from another class, while implements is used for interfaces.

Multiple Interfaces:

A class can implement multiple interfaces in both Java and Salesforce Apex. This is done by separating interface names with commas after the implements keyword.

Correct Syntax:

To create a DrawList class that implements both Sortable and Drawable interfaces, the syntax must:

Use implements for interfaces.

Provide implementations for all methods defined in the interfaces.

Analysis of Options:

Option A:

Uses implements for each interface separately, which is syntactically incorrect in Java/Apex.

Invalid due to redundancy.

Option B:

Correctly uses implements for multiple interfaces separated by a comma.

Provides implementations for both methods, sort() and draw().

Option C and D:

Use extends for interfaces, which is invalid. Interfaces cannot be extended by classes.

Final Implementation:

public class DrawList implements Sortable, Drawable {

public void sort() {

// Implementation of sort method

}

public void draw() {

// Implementation of draw method

}

}

References:

Apex Classes and Interfaces Documentation

Trailhead Module on Apex Interfaces

Option B is the correct implementation as it adheres to the rules for working with interfaces in Java/Apex.

The Lightning component cannot directly perform SOQL queries.

An Apex class annotated with @AuraEnabled provides server-side logic that can execute the SOQL query and return the data to the Lightning component.

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;

}

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).

 Option B: Escapes single quotes using String.escapeSingleQuotes, protecting against SOQL injection.

 Option C: Uses bind variables, which are inherently safe from SOQL injection.

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.

Visual Studio Code (VS Code) is the recommended tool for Salesforce development. It supports the Salesforce Extensions Pack for debugging and fixing issues in Lightning Web Components (LWCs).

Not Suitable:

Option A: The Developer Console is less effective for LWC debugging.

Option B: The Force.com IDE is deprecated.

Option C: Execute Anonymous does not provide tools to debug or fix LWC bugs.

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.

Salesforce Testing Framework

Apex Testing Best Practices

A Flow with an Assignment element is the best declarative solution to assign cases based on criteria such as Case Origin. It can automatically evaluate the value of the Case Origin and assign the support representative.

Why not other options?

A: Using a trigger is a programmatic approach and less ideal when declarative tools can solve the problem.

B: A formula field cannot assign values; it only calculates and displays results.

C: Validation rules are used to enforce constraints, not for assigning values.

References:

Salesforce Flows Overview

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.

Option D correctly defines a property that uses the getAccounts Apex method. It uses the @wire decorator with a parameterized method reference.

@wire(getAccounts, { searchTerm: '$searchTerm' }) accountList;

Why upsert?

The upsert statement inserts records that don’t exist and updates existing records based on the external ID (Order Number__c in this case).

Salesforce automatically recognizes and uses the external ID field for matching.

Why Not Other Options?

A and B: merge is for merging records, not for upserting.

C: Adding the field name after upsert is unnecessary, as Salesforce detects the external ID automatically.

Upsert Documentation:

References:

Infrastructure as a Service (IaaS) is the best model for the scenario described because it provides on-demand access to compute, storage, and networking resources that are ideal for a scalable server cluster. IaaS allows the engineering team to rent infrastructure resources without having to invest in physical hardware, making it perfect for temporary or fluctuating workloads, such as scalability testing.

Key Characteristics of IaaS:

Full control over the operating systems and applications running on the servers.

Flexible resource allocation to support high scalability.

Ideal for custom software testing where specific server configurations may be needed.

Why not the other options?

PaaS (Platform as a Service):While PaaS is excellent for application development and deployment, it abstracts the infrastructure layer, which would limit the engineering team's control over the cluster's configuration.

SaaS (Software as a Service):SaaS delivers fully managed applications, not infrastructure or testing environments. It’s irrelevant for this use case.

BaaS (Backend as a Service):BaaS is tailored to mobile or web application backend development, providing APIs and pre-built services, not infrastructure for a server cluster.

Platform Developer References:While this question is broader than Salesforce-specific concepts, understanding IaaS vs. PaaS is relevant when working with Salesforce development. For example:

Salesforce operates as a PaaS (e.g., Force.com platform), allowing developers to build and deploy applications without managing underlying servers.

Testing scalability and performance at an infrastructure level (as in the question) would fall under IaaS concepts, which Salesforce developers might encounter when integrating external services or infrastructure like AWS, Azure, or Google Cloud.

This foundational knowledge complements your understanding of cloud services in the Salesforce ecosystem.

The Test menu in the Developer Console allows the developer to run specific or all test classes, ensuring that the trigger works correctly without affecting production data. Test methods in Salesforce run in an isolated environment and do not modify the actual data.

Why not other options?

A: Deploying code does not confirm that the trigger works correctly.

B: Creating a new Contact directly modifies production data, which is not recommended.

D: Executing a DML statement in Execute Anonymous directly affects production data and is not a safe testing method.
