Question 7: A developer uses `System.enqueueJob()` to add a Queueable Apex job. What is the maximum number of Queueable jobs that can be chained in a single transaction in production?

5
50
Unlimited
1 (Correct answer)

Correct answer: 1

Only one Queueable job can be enqueued per transaction in production; chaining allows each job to enqueue exactly one more.

Question 8: A developer defines 'public virtual class Animal' and 'public class Dog extends Animal'. What is required for Dog to override a method from Animal?

No special keywords are needed; all methods are overridable by default
The method in Animal must be marked 'virtual' or 'abstract', and Dog must use 'override' keyword (Correct answer)
The method in Animal must be marked 'static'
Dog must use the 'implements' keyword instead of 'extends'

Correct answer: The method in Animal must be marked 'virtual' or 'abstract', and Dog must use 'override' keyword

In Apex, methods can only be overridden if declared virtual or abstract in the parent class, and the subclass must use the override keyword.

Question 9: What is the primary functional difference between SOQL and SOSL?

SOQL searches text fields only, while SOSL queries all field types
SOQL is used in Apex while SOSL is used only in Visualforce
SOSL supports aggregate functions while SOQL does not
SOSL can search across multiple objects simultaneously, while SOQL queries one object at a time (Correct answer)

Correct answer: SOSL can search across multiple objects simultaneously, while SOQL queries one object at a time

SOSL performs text searches across multiple Salesforce objects simultaneously, whereas SOQL queries a single object (with optional subqueries for related objects).

Question 10: What is the benefit of continuous integration in PD1 workflows?

It removes the need for code review
It automatically fixes all bugs
It detects integration issues early through frequent builds and tests (Correct answer)

An explicit update DML call
No additional DML; changes to Trigger.new are saved automatically (Correct answer)
An explicit insert DML call

Correct answer: No additional DML; changes to Trigger.new are saved automatically

In before triggers, modifications to Trigger.new records are saved automatically without requiring a separate DML statement.

Question 12: What is Visualforce in Salesforce?

A tool for integrating with external systems.
A tool for managing user profiles.
A tool for reporting.
A custom user interface framework (Correct answer)

Correct answer: A custom user interface framework

Visualforce is a framework within Salesforce that allows developers to build custom user interfaces and pages using a tag-based markup language similar to HTML. It enables the creation of highly customized and dynamic web pages that integrate seamlessly with Salesforce data and functionality. While still supported, it's an older technology often used for specific custom UI requirements.

Question 13: A developer wants a Flow to pause and resume execution after an external approval is received. Which Flow element supports this?

Assignment Element
Wait Element (Pause) (Correct answer)
Loop Element
Decision Element

Correct answer: Wait Element (Pause)

HTTP request/response pairs triggered before that line
Only the call stack at that line
Variable values, heap contents, and iteration counts at that execution point (Correct answer)
CPU time consumed up to that line only

Correct answer: Variable values, heap contents, and iteration counts at that execution point

Checkpoints in the Developer Console capture a snapshot of heap contents, variable values, and execution counts at that specific line during a transaction.

Question 16: Which Apex class allows a developer to write a test that verifies an entire batch Apex job runs to completion?

Database.BatchableContext
Test.runAllTests()
Test.stopTest() (Correct answer)
AsyncOptions

Correct answer: Test.stopTest()

Calling Test.stopTest() forces all asynchronous operations—including batch jobs—queued between startTest/stopTest to execute synchronously before the method continues.

Question 17: What is the purpose of the 'rendered' attribute in Visualforce components?

It controls whether the component is editable
It sets the CSS display property to none
It determines if the component fires AJAX requests
It conditionally includes or excludes the component from the HTML output (Correct answer)

Correct answer: It conditionally includes or excludes the component from the HTML output

The 'rendered' attribute accepts a Boolean expression; when false, the component is not emitted in the HTML response at all.

Question 18: When a PD1 professional encounters an unexpected result during a technical procedure, the FIRST action should be to:

Repeat the procedure from the beginning immediately
Report the issue without any preliminary assessment
Stop, assess the situation, and determine whether to proceed or seek guidance (Correct answer)

Correct answer: Develop and implement an action plan with measurable goals and timelines

A structured action plan with measurable goals and defined timelines demonstrates commitment to quality improvement. This systematic response ensures that identified issues are addressed effectively and progress can be tracked.

Question 20: Which keyword in an Apex class declaration causes all DML operations inside it to run with the sharing rules of the calling user?

with sharing (Correct answer)
global
without sharing
inherited sharing

Correct answer: with sharing

Declaring a class 'with sharing' enforces the current user's record-level sharing rules during DML and SOQL operations within that class.

Question 21: Which statement correctly describes Apex's handling of unhandled exceptions in a trigger?

The trigger retries automatically up to 3 times
The entire transaction rolls back and the user sees an error message (Correct answer)
The exception is logged silently and the trigger completes partially
The record is saved, but post-processing is skipped

Correct answer: The entire transaction rolls back and the user sees an error message

An unhandled exception in an Apex trigger causes the entire DML transaction to roll back, and Salesforce displays an error to the user.

Question 22: What is the purpose of the @api decorator in a Lightning Web Component?

It exposes a property or method as public, allowing parent components to set it (Correct answer)
It registers the component in the Lightning App Builder
It connects the component to an Apex method
It marks a property as reactive and tracks changes internally

Correct answer: It exposes a property or method as public, allowing parent components to set it

The @api decorator makes a property or method publicly accessible, allowing parent components or App Builder admins to pass values in.

Question 23: Which metadata file controls where a Lightning Web Component can be used (e.g., App Page, Record Page)?

componentName.js-meta.xml (Correct answer)
componentName.json
package.xml
componentName.html

The .js-meta.xml configuration file defines the component's targets (page types), isExposed setting, and properties visible in Lightning App Builder.

Question 24: Which Salesforce feature allows a developer to enforce that a record cannot be saved unless a related record exists?

Required Field Setting
External ID field
Master-Detail with required lookup
Validation Rule (Correct answer)

Correct answer: Validation Rule

A Validation Rule can check for the presence of a related record and block saves when the condition is not met.

Question 25: What happens if a test method contains a DML statement outside of Test.startTest()/Test.stopTest() and the DML count has already reached the limit?

The DML is queued for execution after the test completes
Salesforce automatically wraps excess DML in a savepoint
Salesforce raises the DML limit silently for test context
A LimitException is thrown, failing the test (Correct answer)

Correct answer: A LimitException is thrown, failing the test

Exceeding any governor limit, including DML statements, causes a LimitException that halts and fails the test method.

Question 26: What is a Process Builder in Salesforce?

It's a key tool for streamlining operations.

Question 27: What is a 'formula field' in Salesforce?

A field for performing calculations and displaying results (Correct answer)
A field for storing text values.
A field for managing security settings.
A field for tracking user activity.

Correct answer: A field for performing calculations and displaying results

A formula field in Salesforce is a read-only field that automatically calculates and displays a value based on an expression or formula defined by the user. It can reference other fields, standard functions, or conditional logic to derive its value. This is highly useful for displaying aggregated data, conditional text, or calculated metrics directly on a record without manual input.

Question 28: When deploying metadata using the Salesforce CLI (sf or sfdx), which command deploys source-tracked changes to a scratch org?

sf project deploy start
sf deploy org push
sf source push (Correct answer)
sf org deploy changes

Correct answer: sf source push

sf source push (or sfdx force:source:push) tracks local changes and pushes only modified metadata to a scratch org.

Question 29: Which Lightning Web Component lifecycle hook is called after every render of the component?

disconnectedCallback()
constructor()
connectedCallback()
renderedCallback() (Correct answer)

Correct answer: renderedCallback()

renderedCallback() fires after each render cycle, making it suitable for DOM manipulation after rendering.

Question 30: Which statement BEST describes the relationship between Salesforce Certified Platform Developer 1 certification requirements and industry evolution?

Question 53: In Visualforce, how do you invoke a JavaScript remoting call to an Apex method?

Annotate the Apex method with @RemoteAction and call it via JavaScript using Visualforce.remoting (Correct answer)
Use <apex:callout> tag with the method name
Use Visualforce.remoting.Manager.invokeAction() with the fully qualified method name
Call the Apex method directly using apex.executeAction() in JS

Correct answer: Annotate the Apex method with @RemoteAction and call it via JavaScript using Visualforce.remoting

JavaScript Remoting requires the @RemoteAction annotation on the Apex method, then call it from JS using the Visualforce.remoting.Manager.invokeAction or namespace syntax.

Question 54: Which method should a developer call to check if the running user has read access to a specific field before rendering it in Apex?

Schema.DescribeSObjectResult.isQueryable()
UserInfo.isFieldAccessible()
FieldPermission.canRead()
Schema.SObjectField.getDescribe().isAccessible() (Correct answer)
