Salesforce Platform Developer II Sample Questions (Q160-Q165):

NEW QUESTION # 160
A developer has a requirement to query three fields (Id, Name, Type) from an Account; and first and last names for all Contacts associated with the Account.
Which option is the preferred, optimized method to achieve this for the Account named 'Ozone Electronics'?

Answer: D

NEW QUESTION # 161
A company has code to update a Request and Request Lines and make a callout to their external ERP system's REST endpoint with the updated records.

The callousUtil.makeRestCallout fails with a "You have uncommitted work pending. Please commit or rollback before calling cut' error.
What should be done to address the problem?

A. Change the callousUtil makeRestCallout to an @InvocsblsMethod method.
B. Change the CallousUtill .makeRestCallout to an @future method.
C. Remove the Database. setSavepoint and Database. rollback.

Answer: B

Explanation:
Changing the CalloutUtil.makeRestCallout to an @future method is a way to address the problem of the "You have uncommitted work pending. Please commit or rollback before calling out" error. This error occurs when a DML operation is performed before a callout to an external service, such as a REST endpoint. This is because the DML operation locks the database records and prevents them from being rolled back if the callout fails. To avoid this error, the developer can use the @future annotation to mark the CalloutUtil.makeRestCallout method as asynchronous, which means it will run in a separate thread after the DML operation is committed. This way, the DML operation and the callout will not interfere with each other, and the error will be resolved. Reference: [Asynchronous Apex], [Making Callouts]

NEW QUESTION # 162
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?

A. A flow with an outbound message that contains a session ID1314
B. An Apex trigger that calls an @future method that allows callouts910
C. A platform event that makes a callout to the web application1516
D. A flow that calls an @future method that allows callouts1112

Answer: B

This integration requiremen21t involves two specific needs: sending a custom JSON payload and handling a response that involves updating data in Salesforce. Outbound Messaging (Option C) is a declarative tool, but it is limited to XML/SOAP protocols and cannot send JSON. Therefore, a custom programmatic solution using Apex is required to construct and send the JSON payload to the external REST service.
Since the integration must be triggered by an event in Salesforce (likely the upload or update of a product record), an Apex trigger is the most direct starting point. However, as noted in previous questions, callouts cannot be performed directly within a trigger's execution context because they would block the database transaction. The developer must use asynchronous processing to handle the callout. An @future(callout=true) method is the standard way to achieve this. The trigger captures the necessary data, passes it to the future method, and the future method then performs the HTTP request to the external application.
Once the external application resizes the image, it can use the Salesforce REST API to send the resized file back to Salesforce. While Platform Events (Option D) are a modern alternative for event-driven architectures, they would still require an asynchronous subscriber (like a trigger or a flow) to actually perform the callout, making the Trigger + Future method combination the most straightforward and traditional answer for this PDII scenario.

NEW QUESTION # 163
If a developer wanted to display error messages with the standard Salesforce UI styling, what would they use?

A. <apex:message>
B. <apex:pageMessages>
C. <apex:error>
D. <apex:outputText>

Answer: B

NEW QUESTION # 164
What is the best practice to initialize a Vizualforce page in a test class?

A. Use controller. currentPage. setPage (MyTastfage) ;
B. Use Test. setCurrentPage (Page. MyTeatPage);
C. Use Test. currantPage .getParamatars put (MyTaestPaga) ;
D. Use Test. setCurrentPage MyTestPags;

Answer: B

Explanation:
The best practice to initialize a Visualforce page in a test class is to use Test.setCurrentPage(Page.MyTestPage). This method sets the current page context for the test class and allows the developer to access the page parameters, controller variables, and standard controller methods. This way, the developer can test the functionality and behavior of the Visualforce page and its controller in different scenarios. The other options are either invalid syntax or do not set the current page context.
