NEW QUESTION # 18
A developer has a Visualforce page that automatically assigns ewnership of an Account to a queue upon save. The page appears to correctly assign ownership, but an assertion validating the correct ownership fails.
What can cause this problem?
Answer: B
Explanation:
If the test class does not retrieve the updated value from the database, it will not see any changes made by the page logic. This can cause assertions that check for those changes to fail. The test should query for the most recent value from the database after the operation that is supposed to update the value.
NEW QUESTION # 19
What is a benefit of JavaScript remoting over Visualforce Remote Objects?
Answer: B
Explanation:
JavaScript remoting in Visualforce allows for the execution of complex server-side application logic without the need to refresh the entire page, providing a more dynamic user experience. It supports more complex operations than Visualforce Remote Objects, which are intended for basic CRUD operations.
NEW QUESTION # 20
Exhibit.
Given the code above, which two changes need to be made in the Apex Controller for the code to work? Choose 2 answers
Answer: A,C
Explanation:
Based on the code provided, here are the necessary changes:
Change B is required because the argument in the Apex controller's serverEcho method must match the data type expected by the JavaScript calling the method. The Apex method expects an Object named firstName, which is then cast to a String inside the method. The JavaScript is passing an object with a property firstName, so no change is needed in the JavaScript.
Change D is correct because line 06 is redundant and unnecessary. We can directly use firstName in the return statement as it is already a String type. The get() method is typically used when you have a Map and you need to retrieve a value by its key. Since firstName is already being passed as a String, there's no need to cast it or retrieve it using get().

NEW QUESTION # 21
Universal Containers ne=ds to integrate with several external systems. The process Is Initiated when a record Is created in Salesforce, The remote systems do not require Salesforce to wait for a response before continuing.
What is the recommended best solution to accomplish this?
Answer: B
Explanation:
Platform events provide a robust and scalable way to communicate changes and events from Salesforce to external systems, especially when there is no requirement for Salesforce to wait for a response. They are designed to support event-driven architectures and can handle high volumes of events that can be published and consumed by external systems. Outbound messages, on the other hand, are limited by the need for an acknowledgment response from the target system, which can introduce latency.
NEW QUESTION # 22
A developer is writing code that requires making callouts to an external web service.
Which scenario necessitates that the callout be made in an asynchronous method?
Answer: A
Explanation:
Callouts cannot be made from a synchronous context such as an Apex trigger because they might exceed the maximum execution time, leading to timeouts. Asynchronous methods, such as future or Queueable, are required to handle callouts from triggers.
