SALESFORCE-PD1 Practice Test 25 — 15 Questions

Question 1

A developer needs to verify that a trigger correctly handles bulk data, specifically 250 records. What is the most effective approach?

Accepted Answer

Use a loop to create 250 test records and insert them.. Testing with a collection of records validates bulkification and prevents governor limit exceptions.

Answer

Create a single record in the test class.

Answer

Use @isTest(isParallel=true) to increase speed.

Answer

Execute the trigger from the Developer Console.

Question 2

What is the primary function of the 'Developer Console'?

Accepted Answer

It is a browser-based IDE for developing in Salesforce.. It is an integrated development environment for writing, debugging, and testing Apex.

Answer

It is used for deploying to production.

Answer

It is a tool for end-user reporting.

Answer

It is used for managing user permissions.

Question 3

Which TWO features are provided out-of-the-box by Visualforce when building standard user interfaces? (Choose TWO)

Accepted Answer

Automatic enforcement of CRUD and FLS when using standard controllers.. Option C is correct because Visualforce standard controllers and standard list controllers automatically enforce object-level CRUD permissions and field-level security (FLS) for the running user, so developers get secure data access without writing manual permission checks. Option E is correct because Visualforce automatically maintains the view state (the encrypted, serialized page state stored in the __VIEWSTATE hidden field) across postbacks, preserving form input and component state during form submission and page navigation. Options A, B, and D are not Visualforce out-of-the-box features: Visualforce does not provide client-side reactive shadow DOM encapsulation, it does not compile TypeScript into native browser bytecode (it renders HTML/CSS/JS server-side), and it does not offer real-time bidirectional WebSocket synchronization across browser tabs.

Answer

Client-side reactive shadow DOM encapsulation.

Answer

Automatic compilation of TypeScript into native browser bytecode.

Answer

Real-time bidirectional WebSocket synchronization across all connected browser tabs.

Question 4

An enterprise application requires Apex code to check whether the current user has read access to a specific custom field before displaying it in a custom Lightning Web Component. What is the most appropriate class to use?

Accepted Answer

Schema.DescribeFieldResult. The Schema.DescribeFieldResult class provides methods like isAccessible() to check Field-Level Security (FLS) dynamically.

Answer

System.Security

Answer

UserInfo

Answer

ApexPages.StandardController

Question 5

Which tool or feature in Salesforce Developer Console allows a developer to inspect debug logs and filter them by category and level?

Accepted Answer

Log Inspector. The Logs tab in the Developer Console displays execution logs, and Log Inspector provides detailed analysis tools.

Answer

Checkpoints

Answer

Query Editor

Answer

Anonymous Apex

Question 6

A developer needs to execute logic before a record is inserted into the Database to validate field values and prevent invalid records from saving. Which trigger event should the developer use?

Accepted Answer

before insert. Before insert triggers are used to perform validation, update field values, and prevent records from saving by using the addError() method on the records.

Answer

after update

Answer

after insert

Answer

before update

Question 7

A developer is receiving 'Too many SOQL queries' errors in a trigger. What is the most likely cause?

Accepted Answer

Executing SOQL inside a for loop.. Performing SOQL inside a loop is the primary cause of this error.

Answer

Using too many debug statements.

Answer

Not enough test coverage.

Answer

Using the wrong trigger event.

Question 8

Which TWO actions can a developer perform using standard Visualforce controllers? Choose 2 answers.

Accepted Answer

Perform standard save, delete, and cancel database operations without writing custom Apex code.. Option B is correct because standard Visualforce controllers (such as StandardController) expose built-in save, delete, and cancel actions that automatically handle DML on the associated record, so a developer can wire buttons like <apex:commandButton action="{!save}"/> without writing any custom Apex. Option D is correct because a standard controller binds the Visualforce page to a single sObject record and exposes its fields through merge expressions such as {!Account.Name} or {!Contact.Phone}, letting the page read and display the viewed or edited record's field values. Option A is not correct because standard controllers cannot express custom SQL-like joins or complex multi-object business logic; that requires custom Apex (SOQL/SOSL or Apex controllers). Option C is not correct because standard controllers do not automatically instantiate or invoke web service callouts; callouts must be coded explicitly in Apex. Option E is not correct because overriding standard page layouts is done through configuration (Lightning App Builder, page layout assignment, or Visualforce page overrides), not by a standard controller action.

Answer

Write complex multi-object business logic with custom SQL-like joins.

Answer

Instantiate custom web service callouts automatically.

Answer

Override standard page layouts without any configuration.

Question 9

What is the maximum number of SOQL queries that can be issued in a single synchronous Apex transaction?

Accepted Answer

100. The synchronous governor limit for SOQL queries is 100 queries per transaction.

Answer

50

Answer

200

Answer

500

Question 10

A developer is creating a Lightning Web Component that needs to interact with Salesforce data using Lightning Data Service. Which TWO wire adapters are natively available in the @salesforce/apex or lightning/ui* modules for basic record operations? (Choose TWO)

Accepted Answer

getRecordUi from 'lightning/uiRecordApi'. Option B, getRecordUi from 'lightning/uiRecordApi', is correct because it is a native Lightning Data Service wire adapter that retrieves record layout, metadata, and field data for one or more records, commonly used with User Interface API responses. Option C, getRecord from 'lightning/uiRecordApi', is also correct because it is the standard Lightning Data Service wire adapter for fetching a single record's fields by record ID and fields, without writing Apex. The other options are not valid native wire adapters: getAccountList from 'lightning/accountApi' does not exist, fetchRecord from 'lightning/recordStore' is not a Salesforce module, and queryDatabase from 'lightning/database' is not a Lightning Data Service adapter.

Answer

getAccountList from 'lightning/accountApi'

Answer

fetchRecord from 'lightning/recordStore'

Answer

queryDatabase from 'lightning/database'

Question 11

Which TWO actions can be performed inside a before insert Apex trigger without causing a runtime exception? (Choose two.)

Accepted Answer

Modifying field values on records in Trigger.new directly without a DML statement.. Option A is correct because in a before insert trigger the records in Trigger.new are not yet committed, so you can assign new field values directly on those sObject instances (e.g., rec.MyField__c = 'X') and Salesforce persists them without any DML statement. Option E is correct because calling addError() on a record in Trigger.new during a before insert trigger marks that record as failed, blocks the save, and surfaces the error message to the user, which is a supported pattern in before triggers. Option B is not valid here because Trigger.oldMap is only populated for update and delete events, so in a before insert trigger it is null and accessing it throws a runtime exception. Option C is not allowed because Apex triggers cannot make synchronous HTTP callouts directly; callouts must be asynchronous (e.g., via @future or Queueable) or handled after the transaction. Option D is not allowed because performing an explicit update DML on records already in Trigger.new causes a runtime exception (a record in Trigger.new cannot be updated with DML in a before trigger).

Answer

Accessing Trigger.oldMap to compare previous values.

Answer

Performing an immediate synchronous HTTP callout to an external REST service.

Answer

Executing an explicit update DML statement on records in Trigger.new.

Question 12

A developer needs to convert a String variable containing a numeric value into an Integer in Apex. Which method should be used?

Accepted Answer

Integer.valueOf(). Integer.valueOf() converts a String representation of a number into an Integer primitive.

Answer

String.toInteger()

Answer

Convert.toInteger()

Answer

Integer.parse()

Question 13

What is the purpose of the 'Debug Log' Filter in the Developer Console?

Accepted Answer

To limit the types of events displayed.. The Debug Log Filter in the Developer Console allows developers to limit the types of events (such as Apex, Workflow, Validation, etc.) that are displayed in the debug log. This helps in focusing on specific log categories and reducing noise when troubleshooting. It does not export, run tests, or delete logs.

Answer

To export logs.

Answer

To run tests.

Answer

To delete old logs.

Question 14

Which TWO actions occur automatically when Test.stopTest() is called in an Apex unit test? (Choose two.)

Accepted Answer

All asynchronous queued processes (future, batch, queueable) are run synchronously.. Option A is correct because Test.stopTest() forces all asynchronous Apex that was queued during the test—future methods, batch jobs, and queueable jobs—to execute synchronously before the method returns, allowing the test to assert on their results. Option D is correct because Test.stopTest() also flushes pending asynchronous communications, including email sent via Messaging.sendEmail, so that the messages are dispatched and can be verified with Limits.getEmailInvocations() or by querying EmailMessage records. Option B is wrong because Test.stopTest() does not log out the running user; the test continues executing in the same session context. Option C is wrong because no custom objects are deleted or recreated; test data isolation is handled by the test's own transaction rollback, not by schema changes. Option E is wrong because Test.stopTest() does not commit data to production—all test data changes are rolled back after the test completes.

Answer

The user session is automatically logged out.

Answer

All custom objects in the organization are deleted and recreated.

Answer

The database is permanently committed to production.

Question 15

A developer is building a Lightning Web Component and needs to perform validation on an input field before submission. Which method on a lighting-input element checks validity?

Accepted Answer

checkValidity(). lightning-input exposes a checkValidity() method that returns true if the input satisfies all its constraints (required, minlength, pattern, type-specific validation) and false otherwise, while also firing an invalid event and setting the validity property. It mirrors the native HTMLInputElement.checkValidity() API, which the base component wraps.

Answer

verify()

Answer

isValid()

Answer

validate()
