Question 1
Instead of waiting to send emails to support personnel directly from the finish
method of a batch Apex process, Universal Containers wants to notify an external
system in the event that an unhandled exception occurs.
What is the appropriate publish/subscribe logic to meet this requirement?
- A. Publish the error event using the Eventbus. publish () method.
- B. No publishing is necessary. Have the external system subscribe to the BatchapexErrorEvent.
- C. Publish the error event using the addError method.
- D. Publish the error event with a Flow.
Answer:
B
Explanation:
Use BatchApexErrorEvent for notifications. It's automatically triggered for unhandled exceptions in
batch Apex. No need for manual publishing. External systems can subscribe to this event to receive
notifications.

Question 5
A company manages information about their product offerings in custom objects named Catalog and
Catalog Item. Catalog Item has a master-detail field to Catalog, and each Catalog may have as many
as 100,000 Catalog Items.
Both custom objects have a CurrencylsoCode text field that contains the currency
code they should use. If a Catalog's CurrencylsoCode changes, all of its Catalog
Items’ CurrencylsoCodes should be changed as well.
What should a developer use to update the CurrencylsoCodes on the Catalog Items
when the Catalog's CurrencylsoCode changes?
- A. A Database.Schedulable and Database.Batchacle class that queries the Catalog Item object and updates the Catalog Items if the Catalog CurrencylSoCode is different
- B. An after insert trigger on Catalog that updates the Catalog Items if the Catalogs CurrencylsoCode is different
- C. An after insert trigger on Catalog Item that updates the Catalog Items if the Catalog’s CurrencylsoCode is different
- D. A Database. schedulable and Dazabase.Bazchacle class that queries the Catalog object and updates the Catalog Items if the Catalog CurrencylSoCode is different
Answer:
A
Explanation:
Use Database.Batchable for handling large data sets. It can efficiently process 100,000 Catalog Items
asynchronously and update CurrencylsoCodes.

Question 6
How should a developer assert that a trigger with an asynchronous process has successfully run?
- A. Create all test data in the test class, use system. runs {} to invoke the trigger, then perform assertions.
- B. Insert records into Salesforce, use seeAllData=true, then perform assertions.
- C. Create all test data, use future in the rest class, then perform assertions.
- D. Create all test data in the test class, invoke Test.startTest{} and Test.etopTaat {} and then perform assertions.
Answer:
D
Explanation:
Use Test.startTest() and Test.stopTest(). These methods ensure asynchronous code runs within test
execution and allows for accurate assertions.

Question 7
A company notices that their unit tests in a test class with many methods to create many records for
prerequisite reference data are slow.
What can a developer to do address the issue?
- A. Turn off triggers, flows, and validations when running tests.
- B. Move the prerequisite reference data setup to a TestDataFactory and call that from each test method.
- C. Move the prerequisite reference data setup to a @testSetup method in the test class.
- D. Move the prerequisite reference data setup to the constructor for the test class.
Answer:
C
Explanation:
@testSetup method improves test performance. It allows data sharing across test methods within a
class, reducing redundant data creation.

Question 8
Universal Containers implements a private sharing model for the Convention Attendee co custom
object. As part of a new quality assurance effort, the company created an Event_Reviewer_c user
lookup field on the object.
Management wants the event reviewer to automatically gain ReadWrite access to
every record they are assigned to.
What is the best approach to ensure the assigned reviewer obtains Read/Write access to the record?
- A. Create a before insert trigger on the Convention Attendee custom object, and use Apex Sharing Reasons and Apex Managed Sharing.
- B. Create an after insert trigger on the Convention Attendee custom object, and use Apex Sharing Reasons and Apex Managed Sharing.
- C. Create criteria-based sharing rules on the Convention Attendee custom object to share the records with the Event Reviewers,
- D. Create a criteria-based sharing rule on the Convention Attendee custom object to share the records with a group of Event Reviewers.
Answer:
B
Explanation:
Use Apex Managed Sharing with an after insert trigger. It allows dynamic record sharing based on
user-defined criteria like the Event_Reviewer_c field.
Reference: Apex Managed Sharing
Question 9
Consider the following code snippet:
How should the <e-orders> component communicate to the <c-selected-orders
component that an order has been selected by the user?
- A. Create and fire a component event.
- B. Create and fire an application event.
- C. Create and fire a standard DOM event.
- D. Create and dispatch a custom event,
Answer:

Question 10
A developer is creating a Lightning web component to display a calendar. The component will be
used in multiple countries. In some locales, the first day of the week is a Monday, or a Saturday, or a
Sunday. ‘What should the developer do to ensure the calendar displays accurately for users in every
locale?
- A. Query the FirstDayofweek field from the Locale for the current user.
- B. Import the @salesforce/i18n module and use the firstdayofweek internationalization property.
- C. Use a custom metadata type to store key/value pairs.
- D. Use UserInfo.getLocale() in the component.
Answer:

Question 11
Which statement is considered a best practice for writing bulk safe Apex triggers?
- A. Add records to collections and perform DML operations against these collections.
- B. Add LIMIT 50000 to every SOQL statement.
- C. Perform all DML operations from within a future method.
- D. Use the Database methods with allorNone set to £21s= instead of DML statements.
Answer:
A
Explanation:
Bulk-safe triggers use collections to aggregate DML operations. This practice minimizes the number
of DML statements, which is essential for bulk processing.

A)
B)
C)
D)
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Answer:
C
Explanation:
Test.startTest() and Test.stopTest() should wrap the method call for resource allocation.
Test.setMock() sets a mock callout for the test to handle callouts.
Reference: Apex Developer Guide - Testing HTTP Callouts
Question 14
Refer to the test method below''
The test method calls a web service that updates an external system with Account
information and sets the Accounts integration_Updated__c checkbox to True when it completes.
The test fails to execute and exits with an error: "Methods defined as TestMethod do
not support Web service callouts.”
A)
B)
C)
D)
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Answer:
B
Explanation:
The correct order in tests with callouts is Test.startTest(), then Test.setMock(), followed by the
method invocation, and finally Test.stopTest(). This ensures the mock callout is used.

Question 15
Refer to the following code snippets:
A developer is experiencing issues with a Lightning web component. The component must surface
information about Opportunities owned by the currently logged-in user.
When the component is rendered, the following message is displayed: "Error retrieving data”.
Which modification should be implemented to the Apex class to overcome the issue?
- A. Use the Cacheable=true attribute in the Apex method,
- B. Ensure the OWD for the Opportunity object is Public.
- C. Edit the code to use the w. cut sharing keyword in the Apex class.
- D. Use the Continuation=true attribute in the Apex method.
Answer:
A
Explanation:
The @AuraEnabled(cacheable=true) attribute allows caching of method results on the client side,
reducing server trips for already fetched data, which is useful for read-only data.
