NEW QUESTION # 30
How should a developer verify that a specific Account record is being tested in a test class for a Visualforce controller?
Answer: C
Explanation:
To verify that a specific Account record is being tested in a test class for a Visualforce controller, a developer should insert the Account in the test class, instantiate the page reference in the test class, then use System.currentPageReference().getParameters().put() to set the Account ID. This way, the test class can simulate the behavior of the Visualforce page that receives the Account ID as a URL parameter and passes it to the controller. System.setParentRecordId() and seeAllData=true are not valid methods or annotations in Apex. System.setParentRecordId().get() is not a way to set the Account ID, but to get the ID of the parent record in a master-detail relationship.

NEW QUESTION # 31
A developer is asked to modify a Lightning web component so that it displays in one column on phones and in two columns on tablets, desktops, and larger devices.
Given to the code below:
Which should the developer add to the code to meet the requirements?
Answer: C
Explanation:
The requirement is for the Lightning web component to display in one column on phones and in two columns on larger devices. To achieve this, we should specify the size attributes for different devices using the design tokens provided by the Lightning Design System.
* Option B is correct because size="6" will set each lightning-layout-item to take up half the available space (since the grid system is based on a 12-column structure), creating two columns on tablets, desktops, and larger devices. small-device-size="12" will ensure that on small devices like phones, each item will take up the full width, resulting in a single column.
* Options A, C, and D do not meet the requirement correctly, as they either do not set the size correctly for small devices or do not specify the sizes for both small and larger devices appropriately.

NEW QUESTION # 33
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?
Answer: C
Explanation:
The error occurs because DML operations were performed before a callout. To fix this, the callout should be made from an asynchronous method such as one annotated with @future(callout=true), which allows DML operations to be committed separately from the callout.
