NEW QUESTION # 156
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: D
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 # 158
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? A)
B)
C)
D)
Answer: A
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.
