NEW QUESTION # 46
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?
Answer: A
Explanation:
Visualforce can render pages as PDFs, which Lightning Components cannot do. This functionality is crucial if PDF rendering is required.
NEW QUESTION # 47
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: A
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 # 48
Users report that a button on a custom Lightning web component (LWC) is not saving the data they enter. The button looks to be clicked, but the LWC simply sits there, seemingly doing nothing.
What should the developer use to ensure error messages are properly displayed?
Answer: D
Explanation:
To ensure error messages are properly displayed in a Lightning web component, the developer should use JavaScript to handle errors in the component's client-side code and use HTML to display the message on the UI. This can be combined with Apex exception handling for server-side operations.
NEW QUESTION # 49
A developer needs to send Account records to an external system for backup purposes. The process must take a snapshot of Accounts as they are saved and then make a callout to a RESTful web service. The web service can only receive, at most, one record per call.
What should a developer do to implement these requirements?
Answer: D
NEW QUESTION # 50
As part of point-to-point integration, a developer must call an external web service which, due to high demand, takes a long time to provide a response. As part of the request, the developer must collect key Inputs from the end user before making the callout. Which two elements should the developer use to Implement these business requirements?
Choose 2 answers
Answer: B,D
Explanation:
For implementing business requirements that involve collecting key inputs from the end user before making a long-running callout, a combination of a Lightning web component and an Apex method that returns a Continuation object is ideal. The Lightning web component can be used to build a user-friendly interface to collect the inputs, and the Continuation object in Apex allows for managing the callout in an asynchronous way. This pattern prevents the user interface from freezing and provides a better user experience by allowing the callout to run in the background.
