NEW QUESTION # 76
Universal Containers needs to integrate with their own, existing, internal custom web application. The web application accepts JSON payloads, resizes product images, and sends the resized images back to Salesforce.
What should the developer use to implement this integration?
Answer: B
Explanation:
In a scenario where an integration requires making a callout to an external web application, Apex is often used to perform callouts. The callout must be asynchronous when being made from a trigger because a callout cannot be made from a synchronous operation like a trigger due to the possibility of long-running transactions.
Option A (An Apex trigger that calls an @future method that allows callouts) is correct because it enables the trigger to perform an asynchronous callout to the external web application, which is necessary for sending JSON payloads and receiving the resized images.
Options B, C, and D do not fit the requirement as well as option A because platform events and flows are typically not used for making direct callouts to external systems in the context described.

NEW QUESTION # 78
A company has a web page that needs to get Account record information, such as name, website, and employee number. The Salesforce record 1D is known to the web page and it uses JavaScript to retrieve the account information.
Which method of integration is optimal?
Answer: A
Explanation:
For retrieving specific records using a known ID, the REST API is optimal due to its stateless, cacheable communications and lightweight structure. It's ideal for web applications that use JavaScript to make requests directly from the user's browser. Using the REST API, the web page can make a simple HTTP GET request to the Salesforce REST service endpoint and retrieve the account information in a format that's easily handled by JavaScript (typically JSON).

NEW QUESTION # 79
Refer to the test method below:
The test method calls an @future method that increments the Number_of_Times_Viewed__c value. The assertion is failing because the Number of Times Viewed_c equals 0. What is the optimal way to fix this?
Answer: B
Explanation:
When a test method calls an @future method that performs DML operations, the changes made by the @future method won't be visible until after the Test.stopTest() is called. This method ensures that all asynchronous processes are completed before the test execution continues. Therefore, Test.startTest() should be before the call to the @future method and Test.stopTest() immediately after.
NEW QUESTION # 80
How should a developer verify that a specific Account record is being tested in a test class for a Visualforce controller?
Answer: A
Explanation:
To test a Visualforce controller that works with specific records, you should insert the necessary test data in the test class. Then instantiate a PageReference for the Visualforce page, set the record id in the page parameters, and use System.currentPageReference().getParameters().put('id', recordId) to simulate navigating to the page with that record.
