NEW QUESTION # 15
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: 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 # 16
Universal Containers wants to notify an external system in the event that an unhandled exception occurs when their nightly Apex batch job runs.
What is the appropriate publish/subscribe logic to meet this requirement?
Answer: A
Explanation:
To notify an external system about an unhandled exception in a batch job, the appropriate approach is to have the external system subscribe to a custom Platform Event that gets published using EventBus.publish(). When an exception occurs, the batch job can publish this event which the external system can listen for and respond to accordingly. Reference:

NEW QUESTION # 17
When the sales team views an individual customer record, they need to see recent interactions for the customer. These interactions can be sales orders, phone calls, or Cases. The date range for recent interactions will be different for every customer record type.
How can this be accomplished?
Answer: D
Explanation:
A Lightning component can dynamically query and display interactions based on the customer's record type. The component can receive the record type as a parameter and adjust the query accordingly, providing the required functionality without batch processing or additional configurations.
NEW QUESTION # 18
A company has a custom component that allows users to search for records of a certain object type by invoking an Apex Controller that returns a list of results based on the user's input. When the search is completed, a searchComplete event is fired, with the results put in a results attribute of the event. The component is designed to be used within other components and may appear on a single page more than once.
What is the optimal code that should be added to fire the event when the search has completed?
A)
B)
C)
D)
Answer: C
Explanation:
The correct code to fire the event when the search has completed in a Lightning component is option B. $A.get("e.c.searchComplete") is the syntax used to get the event, setParams is used to set the parameters, and fire is used to dispatch the event.
NEW QUESTION # 19
An org has a requirement that an Account must always have one and only one Contact listed as Primary. So selecting one Contact will de-select any others. The client wants a checkbox on the Contact called 'Is Primary' to control this feature.
The client also wants to ensure that the last name of every Contact is stored entirely in uppercase characters.
What is the optimal way to implement these requirements?
Answer: B
Explanation:
A single trigger on Contact that handles both after update and before update events, utilizing helper classes for each logic set, is the most optimal implementation. It centralizes the logic for maintaining primary contacts and normalizing last names while allowing for clear separation of concerns through helper classes.
