1.A company's engineering department is conducting a month-long test on the scalability of an
in-house-developed software that requires a cluster of 100 or more servers.
Which of the following models is the best to use?
A. PaaS
B. SaaS
C. BaaS
D. laaS
Answer: D
Explanation:
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
Reference: While this question is broader than Salesforce-specific concepts, understandingIaaS vs.
PaaSis relevant when working with Salesforce development.
For example:
Salesforce operates as aPaaS (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
underIaaSconcepts, 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.
2.What are three characteristics of change set deployments? Choose 3 answers Sending a change set
between two orgs requires a deployment connection.
A. Change sets can deploy custom settings data.
B. Change sets can only be used between related organizations.
C. Deployment is done in a one-way, single transaction.
D. Sending a change set between two orgs requires a deployment connection.
E. Change sets can be used to transfer records.
Download Valid Salesforce PLAT-DEV-201 PDF Dumps for Best Preparation
3 / 21
Answer: B,C,D
Explanation:
Change sets can only be used between related organizations:
Change sets require a relationship between the source and target Salesforce orgs, such as a production
org and its sandboxes. You cannot use change sets between unrelated Salesforce orgs.
Reference: Salesforce Change Set Overview
Deployment is done in a one-way, single transaction:
When a change set is deployed, it is applied to the target org as a single transaction. If there are any
errors in the deployment, the entire transaction is rolled back.
Reference: Apex Development Guide
Sending a change set between two orgs requires a deployment connection:
Before sending or deploying a change set, a deployment connection must be established between the
source and target orgs. This connection is configured in the setup menu under "Deployment
Connections."
Reference: Trailhead: Deployment Connections
Incorrect Options:
A. Change sets can deploy custom settings data:
Change sets cannot deploy data, including custom settings data. They only move metadata.
E. Change sets can be used to transfer records:
Records (data) are not supported by change sets; they only facilitate metadata migration.
3.Universal Containers wants to ensure that all new leads created in the system have a valid email
address. They have already created a validation rule to enforce this requirement, but want to add an
additional layer of validation using automation.
What would be the best solution for this requirement?
A. Submit a REST API Callout with a JSON payload and validate the fields on a third party system
B. Use a before-save Apex trigger on the Lead object to validate the email address and display an error
message if it is invalid
C. Use a custom Lightning Web component to make a callout to validate the fields on a third party system.
D. Use an Approval Process to enforce the completion of a valid email address using an outbound
message action.
Answer: B
Explanation:
Before-save Apex Trigger:
This is the best solution because abefore-save triggerruns 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):
Download Valid Salesforce PLAT-DEV-201 PDF Dumps for Best Preparation
4 / 21
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.
Reference: Apex Triggers Documentation
Trigger Context Variables
4.Which statement should be used to allow some of the records in a list of records to be inserted if others
fail to be inserted?
A. Database. insert (records, true)
B. insert records
C. insert (records, false)
D. Database. insert (records, false)
Answer: D
Explanation:
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.
Reference: Apex DML Operations Documentation
Database Methods
5.A developer identifies the following triggers on the Expense _c object:
The triggers process before delete, before insert, and before update events respectively.
Which two techniques should the developer implement to ensure trigger best practices are followed?
Choose 2 answers
A. Unity all three triggers In a single trigger on the Expense__c object that Includes all events.
B. Unify the before insert and before update triggers and use Flow for the delete action.
C. Create helper classes to execute the appropriate logic when a record is saved.
D. Maintain all three triggers on the Expense __c object, but move the Apex logic out of the trigger

definition.
Answer: A,C
Explanation:
A. Unify all three triggersin a single trigger on the Expense__c object that includes all events:
Salesforce best practices recommend having only one trigger per object to avoid redundancy and
conflicts.
By combining all the events (before delete, before insert, and before update) into a single trigger, the
developer can manage the logic in an organized and maintainable manner.
This also simplifies debugging and ensures that the trigger logic executes in a predictable order.
C. Create helper classes to execute the appropriate logic when a record is saved:
Using helper classes allows for a clean separation of concerns. The trigger becomes a dispatcher that
delegates logic to dedicated classes.
For example, you can create methods like applyDefaultsToExpense (), validateExpenseUpdate (), and
deleteExpense () in a helper class and invoke them from the trigger.
This improves reusability, readability, and testability of the code.
Why not the other options?
B. Unify the before insert and before update triggers and use Flow for the delete action:
While Flow is a powerful tool, it is not ideal for deleting records or replacing Apex trigger functionality,
especially when triggers already exist for other events.
D. Maintain all three triggers on the Expense__c object but move the Apex logic out of the trigger
definition:
Maintaining multiple triggers on the same object can lead to conflicts and execution order issues, even if
the logic is moved to helper classes.

6.Which statement generates a list ofLeadsandContactsthat have a field containing the phrase "ACME"?
A. List searchList = [FIND '*ACME*' IN FIELDS RETURNING Contact, Lead];
B. List> searchList = [SELECT Name, Id FROM Contact, Lead WHERE Name LIKE
'%ACME%'];
C. List> searchList = [FIND '*ACME*' IN ALL FIELDS RETURNING Contact, Lead];
D. List searchList = [find 'acme' in all fields returning Contact, Lead];
Answer: C
Explanation:
C (Correct): This is the correctSOSL (Salesforce Object Search Language) syntax. It performs a full-text
search across multiple objects and fields.
The format FIND '*ACME*' IN ALL FIELDS RETURNING Contact, Lead is thestandard and
correctapproach for cross-object keyword searches.
Incorrect options:
A: Incorrect syntax; needs ALL FIELDS or NAME FIELDS, and proper result typing.
B: SOQL does not support searching across multiple objects in a single query.
D: Incorrect casing and structure; missing proper list handling.

7.A developer creates a Lightning web component that imports a method within an Apex class. When a
Validate button is pressed, the method runs to execute complex validations.
In this implementation scenario, which two options are.. of the Controller according to the MVC
architecture? Choose 2 answers
A. HTML file
B. Apex class
C. JavaScript file
D. XML file
Answer: B,C
Explanation:
In the context of the MVC (Model-View-Controller) architecture for a Lightning Web Component (LWC),
the Apex class and JavaScript file are responsible for handling the controller's role:
Apex Class (Controller):
Acts as the server-side controller.
Executes business logic, such as the complex validations mentioned in the scenario.
Exposes methods for the LWC to call using@AuraEnabled.
Reference: https: //developer.salesforce.com/docs/component-library/documentation/en/lwc/lwc.apex
JavaScript File (Controller):
Acts as the client-side controller.
Manages the interaction between the HTML (View) and Apex methods.
Executes functions triggered by user actions, such as clicking the "Validate" button.
Reference: https:
//developer.salesforce.com/docs/component-library/documentation/en/lwc/lwc.js_props_methods
Why Not the Other Options?
A. HTML file: Represents the "View" in MVC, focusing on UI rendering.
D. XML file: Used for metadata configuration and is not part of the controller functionality.
8.What are two use cases for executing Anonymous Apex code? Choose 2 answers
A. schedule an Apex class to run periodically
B. To delete 15,000 inactive Accounts in a single transaction after a deployment
C. To run a batch Apex class to update all Contacts
D. To add unit test code coverage to an org
Answer: B,C
Explanation:
Anonymous Apex allows developers to execute ad hoc code snippets without creating a permanent class
or trigger. It is useful for tasks like bulk data manipulation or testing.
B. Deleting 15,000 inactive Accounts:
Anonymous Apex can perform ad hoc bulk operations to clean up data after a deployment.
Example:
Use Cases: List inactiveAccounts = [SELECT Id FROM Account WHERE IsActive__c = false
LIMIT 15000];
delete inactiveAccounts;
C. Running a batch Apex class:
Download Valid Salesforce PLAT-DEV-201 PDF Dumps for Best Preparation
7 / 21
Anonymous Apex can execute batch jobs for data processing.
Example:
apex
Copy code
Database.executeBatch (new UpdateContactBatch () ) ;
A. Schedule an Apex class to run periodically: This requires a scheduled job, not Anonymous Apex.
D. Add unit test code coverage: Unit tests must be written in test classes and cannot be added using
Anonymous Apex.

9.A developer created a Lightning web component called statuscomponent to be Inserted into the
Account record page.
Which two things should the developer do to make this component available? Choose 2 answers
A. Add lightning_Recordpage to the statuscomponent. js file,
B. Add lightning RecordPage to the statusComp .js-meta.xml file.
C. Set is Exposes to true In the statuscomponent.js-meta.xml file.
D. Add Account to the statusComponent. js-meta.xm1 file.
Answer: B,C
Explanation:
To make an LWC available for use on a record page:
Target Configuration:
Addlightning__RecordPagein the component's.js-meta.xmlfile to specify where the
component can be used.
Expose the Component:
SetisExposedtotruein the.js-meta.xmlfile to make the component available for use.
Example.js-meta.xmlFile: 
57.0
true
lightning__RecordPage
A: Incorrect placement. Thetag must be in the.js-meta.xmlfile, not the JavaScript file.
D: Thetag is used for metadata labeling, not for exposing or targeting a component.

8 / 21
B. Check the debug logs for the batch job.
C. Disable the batch job and recreate it with a smaller number of records.
D. Decrease the batch size to reduce the load on the system.
Answer: A
Explanation:
When troubleshooting batch Apex jobs:
Asynchronous Job Monitoring:
Navigate toSetup > Apex Jobsto 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 jobstatus.
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.

11.What are two benefits of using declarative customizations over code? Choose 2 answer
A. Declarative customizations automatically update with each Salesforce release.
B. Declarative customizations automatically generate test classes.
C. Declarative customizations cannot generate run time errors
D. Declarative customizations generally require less maintenance
Answer: A,D
Explanation:
Declarative customizations, such as workflows, process builder, validation rules, and flows, offer a
no-code approach to customizing Salesforce. Below are the key benefits:
Declarative customizations automatically update with each Salesforce release (A): Salesforce ensures
that declarative tools are automatically updated during new releases, eliminating the need for manual
intervention or code refactoring.
Reference: Salesforce Release Updates
Declarative customizations generally require less maintenance (D): Because declarative tools use
configurations rather than custom code, they are simpler tomanage, troubleshoot, and update. This
significantly reduces the maintenance overhead compared to custom code.
Reference: Trailhead: Build Declarative Applications
Incorrect Options:
B: Declarative tools do not automatically generate test classes. This is specific to Apex code.
C: Declarative customizations can still result in runtime errors, such as invalid field updates or logic
conflicts.

12.Given the following Anonymous block:
What should a developer consider for an environment that has over 10,000 Case records?
What should a developer consider for an environment that has over 10,000 Case records?
A. The transaction will succeed and changes will be committed.
B. The try-catch block will handle exceptions thrown by governor limits.
C. The transaction will fail due to exceeding the governor limit.
D. The try-catch block will handle any DML exceptions thrown,
Answer: C
Explanation:
The code provided processes allCaserecords 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 theSELECTquery retrieves over 50,000 records,
theDatabase.updatecall will hit this limit and throw aSystem.LimitException.
Reference: Apex Governor Limits
Why the Try-Catch Block Fails to Handle Limits (B & D): Governor limit exceptions
(System.LimitException) cannot be caught by try-catch blocks. Therefore, the exception cannot be
handled, and the transaction will fail.

13.A developer is tasked with building a custom Lightning web component to collect Contact information.
The form will be shared among many different types of users in the org. There are security requirements
that only certain fields should be edited and viewed by certain groups of users.
What should the developer use in their Lightning Web Component to support the security requirements?
A. aura-input-failed
B. force-input-failed
C. ui-input-failed
D. lightning-input-failed
Answer: D
Explanation:
When building a Lightning Web Component (LWC) to collect and manage data, developers must ensure
compliance with Salesforce's security model, including field-level security (FLS) and object-level security
(OLS). To meet the requirement of respecting security controls,lightning-input-fieldis
the correct choice.
Why lightning-input-field?
Field-Level Security (FLS): lightning-input-field respects the user’s field-level security settings. This
means users can only view or edit fields that they have permissions for, ensuring compliance with the
organization’s security model.
Object-Level Security (OLS): It respects object-level security, ensuring users cannot access objects they
are restricted from accessing.
Simplified Development: It is part of the Lightning Data Service (LDS), which eliminates the need to write
custom Apex or SOQL queries for CRUD operations, reducing the potential for security gaps.
Dynamic Rendering: Since the component dynamically renders fields based on the user’s permissions,
developers can share the component across various user groups without additional customization.
Declarative Syntax: lightning-input-field simplifies form creation in LWC by using declarative syntax to
bind to record fields directly.
Example Code Implementation:
Reference: LWC Documentation for lightning-input-field
Field-Level Security and Object-Level Security
Best Practices for Lightning Data Service
By using lightning-input-field, the developer ensures adherence to Salesforce's security standards while
providing a reusable and secure solution for capturing and displaying Contact information.

14.Which three Salesforce resources can be accessed from a Lightning web component? Choose 3
answers
A. Static resources
B. All external libraries
C. SVG resources
D. Third-party web components
E. Content asset files
Answer: A,C,E
Explanation:
Lightning Web Components (LWCs) have access to a variety of resources in Salesforce. Below are the
supported resources:
Static Resources (A): You can use static resources to reference JavaScript libraries, images, and other
files needed in an LWC.
Reference: Static Resources in LWC
SVG Resources (C): LWCs can use custom SVG files for icons or other visual elements.
Reference: SVG Resources in LWC
Content Asset Files (E): Content asset files, like images or videos, stored in Salesforce can be accessed
and used in LWC.
Reference: Using Content Assets in LWC
Incorrect Options:
B. All external libraries: Only libraries uploaded as static resources are supported, not directly external
libraries.
D. Third-party web components: While supported, additional configuration is needed to use them
effectively.
15.A developer must create a CreditCardPayment class that provides an implementation of an existing
Payment class.
public virtual class Payment {
public virtual void makePayment (Decimal amount) {
// implementation
}
}
Which is the correct implementation?
A. public class CreditCardPayment extends Payment { public virtual void makePayment (Decimal amount)
{ /* implementation */ } }
B. public class CreditCardPayment implements Payment { public virtual void makePayment (Decimal
amount) { /* implementation */ } }
C. public class CreditCardPayment implements Payment { public override void makePayment (Decimal
amount) { /* implementation */ } }
D. public class CreditCardPayment extends Payment { public override void makePayment (Decimal
amount) { /* implementation */ } }
Answer: D
Explanation:
Download Valid Salesforce PLAT-DEV-201 PDF Dumps for Best Preparation
12 / 21
Comprehensive and Detailed Explanation From Exact Extract:
D (Correct): Since Payment is avirtual class, it can beextended (not implemented like an interface), and its
makePayment method is alsovirtual, which allows it to be overridden using the override keyword.
The use of override is required to redefine a virtual or abstract method from the parent class.
Reference: Apex Developer Guide – Inheritance and Polymorphism
This maps to"Developer Fundamentals"in the PD1 exam, specifically aroundobject-oriented programming
principles.
16.A developer is creating a Lightning web component to show a list of sales records.
The Sales Representative user should be able to see the commission field on each record. The Sales
Assistant user should be able to see all fields on the record except the commission field.
How should this be enforced so that the component works for both users without showing any errors?
A. Use WITH SECURITY_ENFORCED In the SOQL that fetches the data for the component,
B. Use Security.stripInaccessible Le to remove fields inaccessible to the current user.
C. Use Lightning Locker Service to enforce sharing rules and field-level security.
D. Use Lightning Data Service to get the collection of sales records.
Answer: B
Explanation:
UsingSecurity.stripInaccessibleensures compliance with field-level security (FLS) and prevents users
from accessing fields they do not have permission to view. In this scenario:
The commission field is inaccessible to Sales Assistants, andSecurity.stripInaccessiblewill automatically
remove this field from the result set.
It prevents runtime errors when a user without proper access attempts to retrieve restricted fields.
Reference: Apex Developer Guide: Security.stripInaccessible
17.The following code snippet is executed by a Lightning web component in an environment with more
than 2,000 lead records:
Which governor limit will likely be exceeded within the Apex transaction?
A. Total number of SOOL quires issued
B. Total number of DML statements issued
C. Total number of records processed as a result of DML statements
Answer: C
Explanation:
The provided code attempts to update allLeadrecords in an environment with more than 2,000 records.
Download Valid Salesforce PLAT-DEV-201 PDF Dumps for Best Preparation
13 / 21
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 useDatabase.updatewith batching logic.

18.A developer is asked to write helper methods that create test data for unit tests.
What should be changed in the TestUtils class so that its methods are only usable by unit test methods?
A. @isTest above line 03.
B. Add @istest above line 01.
C. Change public to private on line 01.
D. Remove static from line 03.
Answer: B
Explanation:
To ensure that the TestUtils class and its methods are only accessible by unit test methods, the class must
be annotated with the @isTest annotation. This annotation limits the scope of the class and its methods to
test contexts only.
Why @isTest?
Purpose of @isTest:
The @isTest annotation marks a class or method for use exclusively within test scenarios. It prevents the
methods from being accidentally invoked in production code.
This ensures better test isolation and prevents misuse.
Static Test Data Methods:
Marking helper methods for test data creation as @isTest ensures they do not interfere with production
code and are strictly for testing purposes.
Analysis of Options:
Option A: @isTest above line 03:
Incorrect. Applying @isTest only to the createAccount method would work, but the other methods in the
class would still be accessible. This does not satisfy the requirement of restricting the entire class.
Option B: Add @isTest above line 01:
Correct. Annotating the class ensures all methods within the class are accessible only in the context of
tests.
Option C: Change public to private on line 01:
Incorrect. Changing the class to private would cause a compilation error, as top-level classes in
Download Valid Salesforce PLAT-DEV-201 PDF Dumps for Best Preparation
14 / 21
Salesforce cannot be declared private.
Option D: Remove static from line 03:
Incorrect. Removing static does not affect the test scope of the class or its methods. Static methods can
still be invoked, and this does not restrict access to test contexts.
Correct Implementation:
The corrected code would look like this:
@isTest
public class TestUtils {
public static Account createAccount () {
Account acct = new Account () ;
// Set some fields on acct return acct;
}
// Other methods...
}

19.Universal Containers recently transitioned fromClassic to Lightning Experience. One of its business
processes requirescertain values from the Opportunity objectto be sent via anHTTP REST calloutto
itsexternal order management systemwhen the user presses a custom button on the Opportunity detail
page.
Example fields:
Name
Amount
Account
Which two methods should the developer implement to fulfill the business requirement? Choose 2
answers.
A. Create a customVisualforce quick actionthat performs the HTTP REST callout and use it on the
Opportunity detail page.
B. Create anafter update triggeron the Opportunity object that calls a helper method using @future
(callout=true) to perform the HTTP REST callout.
C. Create aLightning component quick actionthat performs the HTTP REST callout and use it on the
Opportunity detail page.
D. Create aRemote Actionon the Opportunity object that executes an Apex immediate action to perform
the HTTP REST callout whenever the Opportunity is updated.
Answer: A,C
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
A (Correct): AVisualforce quick actioncan include Apex logic for a callout, and Visualforce is still valid in
Lightning Experience.
C (Correct): ALightning Web Component (or Aura component) exposed as aquick actioncan perform
callouts via Apex when the user clicks a button. This supports a more modern UI experience.
Incorrect options:
B: @future (callout=true) works but cannot be triggeredsynchronously by a button press. It’s for
background/automated processes.

20.A developer has an integer variable called maxAttempts. The developer needs to ensure that once
maxAttempts is initialized, it preserves its value for the length of the Apex transaction; while being able to
share the variable's state between trigger executions.
How should the developer declare maxAttempts to meet these requirements?
A. Declare maxattempts as a constant using the static and final keywords.
B. Declare maxattempts as a member variable on the trigger definition.
C. Declare maxattempts as a variable on a helper class.
D. Declare maxAttempts as a private static variable on a helper class.
Answer: D
Explanation:
To preserve the value ofmaxAttemptsfor 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?

16 / 21
How should the developer modify the code to ensure best practices are met?
A)
B)
C)
A. Option A
B. Option B
C. Option C
Answer: A
Explanation:
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.
22.A developer deployed a trigger to update the status__c of Assets related to an Account when the
Account’s status changes and a nightly integration that updates Accounts in bulk has started to fail with
limit failures.
Download Valid Salesforce PLAT-DEV-201 PDF Dumps for Best Preparation
17 / 21
What should the developer change about the code to address the failure while still having the code
update all of the Assets correctly?
A. Move all of the logic to a Queveable class that queries for and updates the Assets and call it from the
trigger.
B. Add List assets = [SELECT id, Status_¢ FROM WHERE AccountId = : acctId] to line 14 and
iterate over the assets list in the for loop on line 15.;
C. Add a LIMIT clause to the SOQL query on line 16 to limit the number of Assets queried for an Account.
D. Change the getAssetsToUpdate method to process all Accounts in one call and call it outside of the for
loop that starts on line 03.
Answer: A
Explanation:
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.

efficient. The Distribution Officer advises UC to implement global addresses to allow multiple Accounts to
share a default pickup address. The developer is tasked to create the supporting object and relationship
for this business requirement and uses the Setup Menu to create a custom object called "Global
Address".
Which field should the developer add to create the most efficient model that supports the business need?
A. Add a master-detail field on the Global Address object to the Account object.
B. Add a lookup field on the Global Address object to the Account object.
C. Add a lookup field on the Account object to the Global Address object.
D. Add a master-detail field on the Account object to the Global Address object.
Answer: C

An Account can reference a single default Global Address via a lookup field, allowing multiple Accounts to
share the same address.
This is more efficient than the reverse (lookup on Global Address to Account), as Global Address is the
parent in this relationship.
Avoiding Master-Detail:
Lookup relationships provide flexibility in this use case since Accounts and Global Addresses have
independent lifecycles.
Example: Create a custom lookup field on Account referencing the Global Address object.
24.Universal Containers (UC) uses out-of-the-box order management, that has a Master-Detail
relationship between Order and Order Line Item.
UC stores the availability date on each Order Line Item and Orders are only shipped when all of the Order
Line Items are available.
Which method should be used to calculate the estimated ship date for an Order?
A. Use a LATEST formula on each of the latest availability date fields.
B. Use a CEILING formula on each of the latest availability date fields.
C. Use a DAYS formula on each of the availability date fields and a COUNT Roll-Up Summary field on the
Order.
D. Use a MAX Roll-Up Summary field on the latest availability date fields.
Answer: D
Explanation:
Roll-Up Summary Field:
Since the relationship between Order and Order Line Item is aMaster-Detail, a Roll-Up Summary field can
be used on the Order object.
The MAX function in a Roll-Up Summary field calculates the latest date (the maximum value) among all
the availability dates on the Order Line Items.
Why MAX Roll-Up Summary Field Works:
The latest availability date among the Order Line Items will determine when the entire Order can be
shipped.
Why Not Other Options?
AandB: There is no such formula called "LATEST" or "CEILING" applicable to date fields.
C: A COUNT Roll-Up Summary is irrelevant for calculating dates.

26.Universal Containers has an order system that uses an Order Number to identify an order for
customers and service agents. Order records will be imported into Salesforce.
How should the Order Number field be defined in Salesforce?
A. Indirect Lockup
B. Direct Lookup
C. External ID and Unique
D. Lookup
Answer: C
Explanation:
Why External ID?
The Order Number is used to identify records uniquely, both in Salesforce and in external systems.
Marking it as an External IDensures it can be matched or referenced during data imports and integrations.
Why Unique?
Setting the field as Unique ensures that duplicate values are not allowed for the Order Number.
Why Not Other Options?
A. Indirect Lookup: Used for external object relationships, which is not applicable here.
B. Direct Lookup: Not relevant for unique field identification.
D. Lookup: Used for creating relationships, not for identifying unique fields.

D. Triggers are executed in the order they are created.
Answer: B
Explanation:
When multiple triggers are associated with the same object and event, Salesforce does not guarantee the
order of execution. This is why it is a best practice to consolidate all logic into a single trigger per object
and control execution order using helper classes.
