NEW QUESTION # 77
A developer is asked to develop a new AppFxchange application. A feature of the program creates Survey records when a Case reaches a certain stage and is of a certain Record Type. This feature needs to be configurable, as different Salesforce instances require Surveys at different times. Additionally, the out-of-the-box AppExchange app needs to come with a set of best practice settings that apply to most customers.
What should the developer use to store and package the custom configuration settings for the app?
- A. Custom metadata
- B. Custom settings
- C. Custom labels
- D. Custom objects
Answer: A
Explanation:
Custom metadata is best for storing configurable settings. It's deployable, packageable, and upgradeable. Allows different configurations for different instances.
NEW QUESTION # 78
A company accepts orders for customers in their enterprise resource planning (ERP) system that must be integrated into Salesforce as order_ c records with a lookup field to Account. The Account object has an external ID field, ENF_Customer_ID_c.
What should the Integration use to create new Oder_c records that will automatically be related to the correct Account?
A)
B)
C)
D)
- A. Option B
- B. Option D
- C. Option C
- D. Option A
Answer: D
Explanation:
When integrating external systems with Salesforce and creating records that need to be associated with existing Salesforce records based on an external ID, Salesforce provides the ability to reference an external ID field in a related object directly within a create or update call.
Option A is correct because the upsert operation can be used to either insert new records or update existing ones. By specifying the external ID field (ENF_Customer_ID__c) for the Account relationship, the system will automatically link the Order__c record to the correct Account based on the external ID provided by the ERP system.
Options B, C, and D are incorrect because they do not specifically utilize the capability of referencing an external ID to associate records during an integration process.

NEW QUESTION # 79
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 with a Flow.
- B. Publish the error event using the Eventbus. publish () method.
- C. No publishing is necessary. Have the external system subscribe to the BatchapexErrorEvent.
- D. Publish the error event using the addError method.
Answer: C
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.
NEW QUESTION # 80
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 B
- B. Option A
- C. Option D
- D. Option C
Answer: A
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.
NEW QUESTION # 81
A developer wrote a trigger on Opportunity that will update a custom Last Sold Date field on the Opportunity's Account whenever an Opportunity is closed. In the test class for the trigger, the assertion to validate the Last Sold Date field fails.
What might be causing the failed assertion?
- A. The test class has not implemented seealldata=true in the test method.
- B. The test class has not re-queried the Account record after updating the Opportunity.
- C. The test class has not defined an Account owner when inserting the test data.
- D. The test class is not using System. runs () to run tests as a Salesforce administrator.
Answer: B
Explanation:
The test class may not be re-querying the Account record after updating the Opportunity, which is necessary to verify the updated field values. If the test does not query the database to get the most recent data after the trigger runs, it will not see the changes made by the trigger.
NEW QUESTION # 82

Creating a custom Apex class with methods to determine the appropriate approver is the most suitable approach when dealing with complex logic and the need for flexibility. This approach allows for centralized logic that can be easily maintained and updated as business requirements change.
NEW QUESTION # 84
A company wants to incorporate a third-party weh service to set the Address fields when an Account is inserted, if they have not already been set.
What is the optimal way to achieve this?
- A. Create an Apex trigger, execute a Queueable job from it, and make a callout from the Queueable job.
- B. Create a Process, execute a Quaueable job from it, and make a callout from the Queueable job.
- C. Create a Workflow Rule, execute a Queueable job from it, and make a callout from the Queueable job.
- D. Create a Before Save Flow, execute a Queueable job from it, and make a callout from the Queusable job.
Answer: A
Explanation:
To make a callout to set the Address fields when an Account is inserted without violating the Salesforce limit against callouts from triggers, a developer can use a trigger to execute a Queueable job. The Queueable job can then safely make the callout.
NEW QUESTION # 85
The Account object has a field, Audit_Code_c, that is used to specify what type of auditing the Account needs and a Lookup to User, zudizar_c, that is the assigned auditor. When an Account is initially created, the user specifies the Audit_Code c. Each User in the org has a unique text field, Audit_Code _e, that is used to automatically assign the correct user to the Account's Auditor_c field.
What should be changed to most optimize the code's efficiency? Choose 2 answers
- A. Build a Map<string, List<Account>> of audit code to accounts.
- B. Build a Map<Id, List<string>>of Account Id to audit codes.
- C. Add a WHERE clause to the SOQL query to filter on audit codes.
- D. Add an initial SOQL query to get all distinct audit codes.
Answer: A,C
Explanation:
To optimize the code's efficiency when assigning users to the Account's Auditor field based on the audit code, the following changes should be considered:
B . Building a map of audit code to accounts (Map<string, List<Account>>) would allow for efficient grouping of accounts by their audit code. This would make it easier to process accounts with the same audit code in a single operation, reducing the number of SOQL queries and DML operations needed.
D . Adding a WHERE clause to the SOQL query to filter on audit codes would limit the number of records returned by the query. This means the code only processes relevant User records with matching audit codes, thereby reducing the processing time and memory consumption.
Option A is not recommended because querying for all distinct audit codes without any context of the accounts being processed could be inefficient. Option C is less effective because it would involve creating a mapping of Account Ids to audit codes, which doesn't aid in the efficient assignment of auditor to accounts.

NEW QUESTION # 86
A developer wrote a class named asccuntRisteryManager that relies on field history tracking. The class has a static method called getaccountHistory that Lakes in an Account as a parameter and returns a list of associated accountHistory object records.
The following test fails:
What should be done to make this test pass?
- A. Use Test. isRunningTest (] in getAccountHistory() to conditionally return fake AccountHistory records.
- B. Use @isTest (SeeAllData=true] to see historical data from the org and query for Accountdistory records.
- C. The tact method should he delated since this code cannat be tested
- D. Create Accountdistory records manually in the test setup and write a query to get them.
Answer: B
Explanation:
To make the test pass, @isTest(SeeAllData=true) should be used to allow the test to access historical data from the org. This is required because field history tracking data is not copied to a test context, so you need to allow the test to access live data to assert against it.
NEW QUESTION # 87
A developer is trying to decide between creating a Visualforce component or a Lightning component for a custom screen.
Which functionality consideration impacts the final decision?
- A. Will the screen make use of a JavaScript framework?
- B. Does the screen need to be rendered as a PDF without using a thirdparty application?
- C. Will the screen be accessed via a mobile app?
- D. Does the screen need to be accessible from the Lightning Experience UI?
Answer: B
Explanation:
Visualforce can render pages as PDFs, which Lightning Components cannot do. This functionality is crucial if PDF rendering is required.
NEW QUESTION # 88
A developer is tasked with creating a Lightning web component that allows users to create a Case for a selected product, directly from a custom Lightning page. The input fields in the component are displayed in a non-linear fashion on top of an image of the product to help the user better understand the meaning of the fields.
Which two components should a developer use to implement the creation of the Case from the Lightning web component?
Choose 2 answers
- A. lightning-input-fimld
- B. Lightning-record-edit-forth
- C. lightning-record-form
- D. Lightning-input
Answer: C,D
Explanation:
To implement a Lightning web component that allows users to create a Case, you would need components that allow for input fields and the creation of records.
Option C (Lightning-input) is correct because it allows developers to create custom form input elements that can be positioned in a non-linear fashion as required.
Option D (lightning-record-form) is correct because it provides a simple way to create forms for viewing and editing Salesforce records and would be suitable for creating a new Case record.
Option A (Lightning-record-edit-form) is not a valid component; it seems to be a misprint of lightning-record-edit-form, which is indeed a component used for creating and editing records but was not listed as an option.
Option B (lightning-input-field) is used within the lightning-record-edit-form or lightning-record-view-form components to create editable or displayable fields respectively, but is not as versatile as lightning-input for custom layout purposes.

NEW QUESTION # 89
A developer wrote a test class that successfully asserts a trigger on Account, It fires and updates data correctly In a sandbox environment.
A Salesforce admin with a custom profile attempts to deploy this trigger via a change set into the production environment, but the test class falls with an Insufficient privileges error.
What should a developer do to fix the problem?
- A. Configure the production environment to enable"Run All Tests as Admin User."
- B. Add seeallData=true to the test class to work within the sharing model for the productionenvironment.
- C. Verify that Test. startTest() Is not Inside a For loop in the test class,
- D. Add System.runAs() to the test class to execute the trigger as a user with the correct objectpermissions.
Answer: D
Explanation:
When a test class fails with an "Insufficient privileges" error during deployment, it indicates that the user profile under which the tests are being executed doesn't have the necessary permissions to perform the actions required by the test. In a sandbox, the test might have been running with a different set of permissions compared to the production environment.
By using System.runAs(), you can specify a user context in which the test should run, which allows you to simulate the appropriate permissions. For this to work, you need to create a User instance in your test class with the profile that has the necessary permissions and then enclose the logic of your test within a System.runAs() block with this user.
This is a preferred solution over seeAllData=true, which would give the test access to all data in the production environment, potentially leading to tests that are not isolated and thus less reliable. It's also preferred over changing organization-wide settings or relying on specific setup in test classes, such as making sure Test.startTest() is not inside a loop.

NEW QUESTION # 90
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. Use a custom metadata type to store key/value pairs.
- B. Use UserInfo.getLocale() in the component.
- C. Import the @salesforce/i18n module and use the firstdayofweek internationalization property.
- D. Query the FirstDayofweek field from the Locale for the current user.
Answer: C
Explanation:
Use the @salesforce/i18n module with the firstDayOfWeek property. It provides locale-aware functionality essential for internationalization.
NEW QUESTION # 91
Consider the above trigger intended to assign the Account to the manager of the Account's region, Which two changes should a developer make in this trigger to adhere to best practices?
- A. Use a Map to cache the results of the Region._c query by Id.
- B. Remove the last line updating accountList as It Is not needed.
- C. Use a Map accountMap instead of List accountList.
- D. Move the Region__c query to outside the loop.
Answer: B,D
Explanation:
Moving the SOQL query outside the loop prevents it from being executed multiple times, which can lead to hitting governor limits. The last line updating the accountList is indeed needed to save the changes made to the Account records, so removing it is not recommended. Instead, the query should be moved outside the loop and records should be collected in a map for efficiency, which is not one of the provided options. Reference:

NEW QUESTION # 92
A business currently has a process to manually upload orders from its external Order Management System (OMS) into Salesforce.
This is a labor intensive process since accounts must be exported out of Salesforce to get the IDs. The upload file must be updated with the correct account IDs to relate the orders to the corresponding accounts.
Which two recommendations should make this process more efficient?
Choose 2 answers
- A. Identify unique fields on Order and Account and set them as External IDs.
- B. Ensure the data in the file is sorted by the order ID.
- C. Use the insert wizard in the Data Loader to import the data.
- D. Use the upsert wizard in the Data Loader to import the data.
Answer: A,D
Explanation:
Setting unique fields on related objects as External IDs allows for the creation of relationships during imports without needing Salesforce IDs. The upsert operation in Data Loader can then use these External IDs to relate records, which streamlines the process and avoids the need to export Salesforce IDs manually.
