PDI Salesforce Certified Platform Developer 1 (WI25) Questions and Answers

Given that Trainer__c has a lookup field to Gym__c, to retrieve the record for the 'Viridian City Gym' and all its trainers, the correct SOQL query is:

Option A:

SELECT Id, (SELECT Id FROM Trainers__r) FROM Gym__c WHERE Name = 'Viridian City Gym'

Parent-to-Child Query (Subquery):

To retrieve child records (trainers) from the parent record (gym), you perform a subquery using the child relationship name.

Child Relationship Name:

For a lookup relationship, the child relationship name can be found in the relationship settings.

By default, if the lookup field on Trainer__c is Gym__c, the child relationship name is Trainers__r.

Query Breakdown:

SELECT Id, (SELECT Id FROM Trainers__r) FROM Gym__c WHERE Name = 'Viridian City Gym'

Selects the Gym record and all related Trainers.

Why Other Options Are Incorrect:

Option B: (SELECT Id FROM Trainer__c)

Trainer__c is an object, not a relationship name, so the subquery is incorrect.

Option C: SELECT ID FROM Trainer__c WHERE Gym__r.Name = 'Viridian City Gym'

This query retrieves Trainer records, not the Gym record and its trainers as specified.

Option D: (SELECT Id FROM Trainers__c)

Trainers__c is incorrect; the child relationship name should end with __r in subqueries.

To ensure that the Apex class is functioning according to the specified requirements, the developer should write a test class that executes the business logic and verifies that it behaves as expected.

Option A: Create a test class to execute the business logic and run the test in the Developer Console.

Correct Approach.

Explanation:

Writing a test class allows the developer to create unit tests that verify the functionality of the Apex class.

Test methods can assert that the class behaves as intended under various conditions, ensuring compliance with requirements.

Running the test in the Developer Console allows the developer to see the results and debug if necessary.

Benefits:

Automated Testing: Ensures repeatability and consistency in testing.

Code Coverage: Helps achieve required code coverage for deployment.

Regression Testing: Facilitates detection of future changes that might break existing functionality.

To efficiently generate a baseline set of data for unit tests that can be shared across multiple test methods, you should:

Option A: Use @TestSetup with a void method.

@TestSetup Annotation:

The @TestSetup method runs once before any test methods in the test class and is used to create common test data.

Data created in @TestSetup is available to all test methods within the test class.

Example:

@IsTest

private class MyTestClass {

@TestSetup

static void setupData() {

// Create Accounts, Contacts, Products, Assets

// This data is available to all test methods

}

@IsTest

static void testCase1() {

// Test logic here

}

@IsTest

static void testCase2() {

// Test logic here

}

}

Option A: Specifying loading order

True.

Explanation:

The tag allows you to specify the order in which scripts are loaded by the sequence in the scripts attribute.

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

To implement a process where every time an Opportunity is created, a follow-up Task should be created and assigned to the Opportunity Owner, the most efficient method is to use a Record-Triggered Flow on the Opportunity object.

Option B: Record-triggered flow on Opportunity

Declarative Solution: Salesforce Flows provide a powerful, declarative way to automate business processes without writing code.

Triggering Event: The flow is configured to trigger when a new Opportunity record is created.

Create Task Record: The flow includes an element to create a new Task record.

Set the Assigned To field to the Opportunity Owner.

Populate other Task fields as necessary (e.g., Subject, Due Date).

Efficiency: Flows are more efficient than Apex triggers for simple automation and are easier to maintain.

Best Practice: Salesforce recommends using Flows over Workflow Rules and Process Builders for new automations.

When using purely declarative development to build the business logic layer in Salesforce, the following options are available:

Option A: Validation Rules

Explanation: Validation rules are declarative tools that enforce business rules on record data entry, ensuring data integrity.

To check the code coverage of a class after running all tests, a developer can use the Developer Console.

Option B: View the code coverage percentage for the class using the Overall Code Coverage panel in the Developer Console Tests tab.

Correct Method.

Explanation:

In the Developer Console, navigate to the Tests tab.

After running tests, the Overall Code Coverage panel displays code coverage statistics.

You can see the coverage percentage for individual classes.

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.

Since users can see Accounts they do not own in a private sharing model, the custom Apex code is likely not enforcing sharing rules. To enforce sharing permissions, the developer should use the with sharing keyword on the class declaration.

with sharing Keyword: This enforces the sharing rules of the current user, ensuring that the Apex class respects the user's record-level access permissions.

"Use the with sharing keyword when declaring a class to enforce the sharing rules that apply to the current user."— Apex Developer Guide: Using the with sharing or without sharing Keywords

Private Sharing Model: In a private sharing model, users should only see records they own or have been shared with them.

"Private: Only the record owner and users above that role in the hierarchy can view, edit, and report on those records."— Salesforce Help: Organization-Wide Sharing Defaults

Why Not Other Options:

A. Use the schema describe calls to determine if the logged-in user has access to the Account object: Schema describe calls check for object-level access, not record-level sharing.

"Schema describe information provides metadata about object and field properties, but it doesn't enforce record-level access."— Apex Developer Guide: Schema Namespace

C. Use the without sharing keyword on the class declaration: This runs the class in system context, ignoring sharing rules, which is the opposite of what's needed.

"Classes declared as without sharing or those that do not specify a keyword default to without sharing and don't enforce the sharing rules of the current user."— Apex Developer Guide: Using the with sharing or without sharing Keywords

D. Use the UserInfo Apex class to filter all SOQL queries to return records owned by the logged-in user: Manually filtering queries is error-prone and not a best practice when with sharing can enforce sharing automatically.

"Avoid hardcoding user or profile IDs and using the UserInfo class to enforce security. Instead, use declarative security features."— Apex Developer Guide: Enforcing Security in Apex

Conclusion: By declaring the class with with sharing, the Apex code respects the user's sharing rules, ensuring that users only see Accounts they have access to.

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.

When using Salesforce DX, developers need to enable the Dev Hub in their org to create and manage scratch orgs.

Option A: Dev Hub

Correct Answer.

Explanation:

The Dev Hub is a feature that must be enabled in a Salesforce org (usually in a Developer Edition or a production org).

It allows developers to create and manage scratch orgs using Salesforce DX commands.

Dev Hub is the central point for creating and managing your scratch orgs.

The first step in the Salesforce order of execution:

Option D: The original record is loaded from the database.

This is Step 1 in the order of execution.

Why Not Other Options:

Option A: Overwriting old values happens after loading the record.

Option B: JavaScript validation occurs on the client side before server processing.

Option C: System validation for field lengths happens after loading the record.

References:

Order of Execution:

"1. Loads the original record from the database or initializes the record for an upsert statement."— Apex Developer Guide: Triggers and Order of Execution

Declarative Development refers to building applications using Salesforce's point-and-click tools without writing code. It has several characteristics:

Option C: Declarative development does not require Apex test classes.

True.

Declarative tools like Flows, Process Builder, and Validation Rules do not require Apex test classes because they are configured via the UI and not through code.

Scenario:

Objects Involved:

Job__c (Master)

Job_Application__c (Detail)

Contact (Related via Master-Detail relationship on Job_Application__c)

Fields:

Preferred_Locations__c (Multi-select picklist on Job__c)

MailingState (Field on Contact)

Requirement:

On Job_Application__c, display whether the Contact's MailingState matches any value in Preferred_Locations__c on the related Job__c.

Keep this value in sync if changes occur to the Contact's MailingState.

Solution:

Option C: Formula field

Correct Approach.

Explanation:

Create a Formula Field on Job_Application__c that compares the Contact's MailingState with the Job's Preferred_Locations__c.

Since Job_Application__c is a detail of Job__c and has a lookup to Contact, the formula can reference fields from both related objects.

Use the INCLUDES() function to check if the MailingState is among the selected values in Preferred_Locations__c.

Sample Formula:

INCLUDES(Job__r.Preferred_Locations__c, Contact__r.MailingState)

This formula returns a Boolean (TRUE or FALSE) indicating whether there's a match.

Benefits:

Real-Time Calculation: Updates automatically when either field changes.

No Code Required: Declarative solution using formula fields.

Maintenance: Easy to manage and update if needed.

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.

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.

A SOQL query can return the following data types:

Option A: sObject

Explanation: A SOQL query can return a single sObject when the query returns only one record.

Example:

Account acc = [SELECT Id, Name FROM Account WHERE Id = :accountId];

Option D: List

Explanation: A SOQL query can return a list of sObjects when multiple records are retrieved.

Example:

List contacts = [SELECT Id, Name FROM Contact WHERE AccountId = :accountId];

Option E: Integer

Explanation: When using aggregate functions like COUNT(), SOQL can return an Integer value.

Example:

Integer contactCount = [SELECT COUNT() FROM Contact WHERE AccountId = :accountId];

Why Other Options Are Incorrect:

Option B: Double

Aggregate functions like SUM() return Decimal, not Double.

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.

Option A: Developer and Developer Pro sandboxes have different storage limits.

True.

Explanation:

Developer Sandbox:

Provides 200 MB of data storage and 200 MB of file storage.

Developer Pro Sandbox:

Provides 1 GB of data storage and 1 GB of file storage.

The storage limits affect how much data you can import into these environments.

To ensure that the variables creditAmount and debitAmount cannot change once assigned, the final keyword should be used.

Option B: Use the final keyword and assign its value in the class constructor.

Declaring a variable as final allows it to be assigned once.

Assigning the value in the constructor is acceptable for instance variables.

Option D: Use the final keyword and assign its value when declaring the variable.

Assigning the value at declaration ensures it cannot be changed later.

Why Not Other Options:

Option A: Using static with assignment in the constructor is invalid because static variables belong to the class, not instances.

Option C: Using static and assigning in a static initializer doesn't prevent reassignment unless final is also used.

References:

Final Variables:

"You can declare instance variables as final. A final variable can only be assigned a value once, either when you declare it or in the constructor."— Apex Developer Guide: Classes, Objects, and Interfaces

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.

When multiple triggers are associated with the same object and event, Salesforce does not guarantee the order in which they will execute.

Option D: Trigger execution order cannot be guaranteed.

Correct Answer.

Explanation:

Salesforce does not provide a mechanism to define or guarantee the execution order of triggers on the same object and event.

If order is important, developers should combine the logic into a single trigger or use trigger frameworks that manage execution order.

When deciding between SOQL (Salesforce Object Query Language) and SOSL (Salesforce Object Search Language), developers must consider the use case and limitations of each.

Option A: SOSL is faster for text searches.

Correct Statement.

Explanation:

SOSL is optimized for searching text, especially across multiple objects and fields.

It uses full-text search indexes and can quickly find records that match search terms.

Ideal for scenarios where you need to search for a string across many fields.

To check whether the current user has permission to delete an Account, the developer should use the Schema.sObjectType methods.

Option D: Schema.sObjectType.Account.isDeletable()

Correct Method.

Explanation:

The Schema.sObjectType.Account provides describe information about the Account object.

The isDeletable() method returns a Boolean indicating whether the current user has permission to delete records of this type.

Usage:

if (Schema.sObjectType.Account.isDeletable()) {

// User has permission to delete Accounts

delete accountRec;

} else {

// Handle lack of permission

}

Options Not Applicable:

Option A: Account.isDeletable()

No such static method on the Account object.

Option B: accountRec.sObjectType.isDeletable()

sObjectType returns a token; to get describe results, you need to call getDescribe().

Option C: accountRec.isDeletable()

There is no instance method isDeletable() on sObject records.

Conclusion:

To ensure proper permission checks, the developer should use Schema.sObjectType.Account.isDeletable(), which is Option D.

When creating a Visualforce page that uses a standard controller and a controller extension for a custom object named Notice__c, the correct syntax is:

Option D: apex

standardController="Notice__c" extensions="myControllerExtension"

Correct Syntax.

standardController attribute specifies the standard controller for the custom object Notice__c.

extensions attribute specifies the name of the Apex class myControllerExtension that extends the functionality of the standard controller.

To meet the given requirements, we need a relationship that allows:

Calculating the total amount on an Order.

This can be achieved using roll-up summary fields on the Order object to sum up values from its Line Item child records.

Roll-up summary fields are only available on the master object in a master-detail relationship.

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.

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.

Scratch Orgs are disposable Salesforce orgs that can be created quickly and configured with different features and settings. They are ideal for source-driven development and allow developers to work independently.

Option D: Scratch orgs

Correct Answer.

Scratch orgs support source-driven development and can be fully configured through scripts and the Salesforce CLI.

Developers can create and destroy scratch orgs as needed, ensuring they have isolated environments.

Using Database.insert with allOrNone=false allows partial success in DML operations.

Option D: Use the Database method with allOrNone set to false.

Records that cause errors are not inserted.

Successful records are committed.

Prevents the entire batch from failing.

Why Not Other Options:

Option A: Deactivating the trigger is not practical.

Option B: Removing the class from the profile may cause other issues.

Option C: A try-catch block won't prevent the batch from failing.

References:

Database Methods:

"Use the Database DML methods to specify whether or not to allow partial record processing."— Apex Developer Guide: Using the Database Class

To send an outbound message when a record meets specific criteria without using Apex code, we can use features that support outbound message actions.

Option B: Approval Process can be used to check the record criteria and send an outbound message without Apex code.

Correct Feature.

Explanation:

An Approval Process can include outbound message actions.

When a record enters a specific step of the approval process, an outbound message can be sent.

Criteria can be defined to determine when the approval process starts.

When a batch Apex job is timing out and not completing, the first step in troubleshooting is to check the job's status and logs in the Asynchronous Job Monitoring page. This page provides information about all asynchronous Apex jobs, including batch Apex, scheduled Apex, future methods, and queueable Apex.

Option D: Check the asynchronous job monitoring page to view the job status and logs.

Correct Approach.

Explanation:

The Asynchronous Job Monitoring page (also known as the Apex Jobs page) in Salesforce Setup allows developers to see the status of all asynchronous Apex jobs.

By checking this page, the developer can see whether the batch job is still running, failed, or completed.

If the job has failed, the page provides error messages that can help identify the cause of the failure.

This is the first step to determine what is happening with the batch job.

To associate multiple Engineering_Support__c records to a single Opportunity and display aggregate information on the Opportunity:

Option B: Master-detail field from Engineering_Support__c to Opportunity

Explanation:

Master-Detail Relationship: Creating a master-detail relationship from Engineering_Support__c (detail) to Opportunity (master) allows multiple support records to be related to one Opportunity.

Aggregate Information: Master-detail relationships support roll-up summary fields, enabling aggregate calculations (like COUNT, SUM) on the Opportunity object based on related Engineering_Support__c records.

In Salesforce, triggers are executed in response to specific database events on standard objects (such as Account or Contact) and custom objects. The following actions can cause triggers to fire:

Option A: Cascading delete operations

Explanation: When a record is deleted, and it has child records in a master-detail relationship, the child records are automatically deleted (cascade delete). This action fires the before delete and after delete triggers on the child records.

To ensure that the component works for both users without showing errors due to field-level security, the developer should handle field accessibility programmatically.

Option D: Use Security.stripInaccessible to remove fields inaccessible to the current user.

Correct Answer.

Explanation:

The Security.stripInaccessible method can be used in Apex to remove fields from SObjects that the current user doesn't have access to.

When data is fetched using SOQL, the method can be applied to ensure that inaccessible fields are not included, preventing any security exceptions when the component tries to display them.

This method enforces field-level security and prevents exposure of inaccessible data.

Usage:

// Apex Controller

public with sharing class SalesRecordsController {

@AuraEnabled(cacheable=true)

public static List getSalesRecords() {

List records = [SELECT Id, Name, Commission__c, Other_Field__c FROM Sales_Record__c];

return (List) Security.stripInaccessible(AccessType.READABLE, records);

}

}

Option C: In a test setup method, test data is inserted once and made available for all test methods in the test class.

True.

The @testSetup method runs once before any test methods in the class.

Test data created in this method is available to all test methods, promoting code reuse and efficiency.
