NEW QUESTION # 189
A company has a custom component that allows users to search for records of a certain object type by invoking an Apex Controller that returns a list of results based on the user's input. When the search is completed, a searchComplete event is fired, with the results put in a results attribute of the event. The component is designed to be used within other components and may appear on a single page more than once.
What is the optimal code that should be added to fire the event when the search has completed?
A)
B)
C)
D)
Answer: D
Explanation:
The correct code to fire the event when the search has completed in a Lightning component is option B. $A.get("e.c.searchComplete") is the syntax used to get the event, setParams is used to set the parameters, and fire is used to dispatch the event.
NEW QUESTION # 190
Business rules require a Contact ta always be created when a new Account is created.
What can be used when developing a custom screen to ensure an Account is not created if the creation of the Contact fails?
Answer: D
Explanation:
When developing a custom screen that requires both an Account and Contact to be created together, using setSavepoint() and rollback() within a try-catch block is a reliable way to ensure that if the Contact creation fails, the Account creation is also rolled back, maintaining data integrity.
NEW QUESTION # 191
Consider the following code snippet:
As part of the deployment cycle, a developer creates the following test class:
When the test class runs, the assertion fails. Which change should the developer implement in the Apex test method to ensure the test method executes successfully? A)
B)
C)
D)
Answer: D
Explanation:
To ensure that test methods execute successfully and are able to verify the behavior of the code, it is important to set up the proper context and to make sure that the test covers the expected outcomes accurately.
Option B is correct because enclosing the method call within Test.startTest() and Test.stopTest() ensures that any asynchronous operations are completed before the assertions are made. This is crucial when the code being tested is expected to perform operations that may run after the initial transaction, such as future methods, queueable jobs, or batch operations.
Options A, C, and D are incorrect because they do not address the issue of ensuring that all operations are completed before the assertion is made. Option A incorrectly suggests modifying the test setup code, while Options C and D suggest changes that are not related to the test execution flow.

NEW QUESTION # 192
Consider the following code snippet:
A developer created the following test class to provide the proper code coverage for the snippet above:
However, when the test runs, no data is returned and the assertion fails. Which edit should the developer make to ensure the test class runs successfully?
Answer: B
Explanation:
To ensure that the test class for a search functionality in Salesforce runs successfully, the developer should use the Test.setFixedSearchResults() method. This allows the test to specify the records that are returned by the search, ensuring that the search behavior is predictable and that the assertion can be properly evaluated.
NEW QUESTION # 193
A company uses Salesforce to sell products to customers. They also have an external product information management (PIM) system that is the system of record for products.
A developer received these requirements:
* Whenever a product is created or updated in the PIM, a product must be created or updated as a Product? record in Salesforce and a PricebookEntry record must be created or updated automatically by Salesforce.
= The PricebookEntry should be created in a Priceboek2 that is specified in a custom setting.
What should the developer use to satisfy these requirements?
Answer: C
Explanation:
Custom Apex REST services are the optimal solution for integrating Salesforce with an external PIM system. When a product is created or updated in the PIM, the external system can make a REST call to a custom Apex REST endpoint in Salesforce, which then can create or update the Product2 and PricebookEntry records. This method allows using custom settings to determine the Pricebook2 dynamically.
