NEW QUESTION # 157
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.

NEW QUESTION # 158
A developer wrote an Apex class to make several callouts to an external system.
If the URLs used in these callouts will change often, which feature should the developer use to minimize changes needed to the Apex class?
Answer: A
Explanation:
The correct feature to use is C, Named Credentials. Named Credentials are a secure way of storing the endpoint and authentication details for callouts to external services. When URLs change frequently, using Named Credentials allows you to manage the endpoint URL in one place without changing the Apex code.

A developer is creating a page in App Builder that will be used in the Salesforce mobile app.
Which two practices should the developer follow to ensure the page operates with optimal performance?
Choose 2 answers
Answer: A,D
Explanation:
For mobile app pages in App Builder, best practices include limiting the number of heavy components like Tabs and Accordion because they can negatively impact performance due to increased client-side processing and data transfer. Also, using Performance Analysis in App Builder helps in identifying components that may slow down page performance and provides recommendations for improvements. Reference:

NEW QUESTION # 160
A developer sees test failures in the sandbox but not in production. No code or metadata changes have been actively made to either environment since the sandbox was created.
Which consideration should be checked to resolve the issue?
Answer: D
Explanation:
If test failures are occurring in a sandbox but not in production and there have been no active code or metadata changes, it could be due to differences in the Salesforce release versions between the two environments. Sandboxes can be on preview instances which get upgraded to new releases before production instances. This can lead to differences in behavior and could affect test executions. Ensuring that both the sandbox and production are on the same release can resolve such issues. API version differences and parallel testing settings typically do not cause discrepancies if the code hasn't changed, and while using SeeAllData=true is generally not recommended due to its dependence on the organization's data, it's unlikely to be the cause if the issue is related to the environment rather than the data.

NEW QUESTION # 161
Given the following containment hierarchy:
What is the correct way to communicate the new value of a property named ''passthrough'' to my-parent-component if the property is defined within my-child-component?
A)
B)
C)
D)
Answer: C
Explanation:
To communicate a property change up a containment hierarchy in Lightning Web Components (LWC), the child component should dispatch a custom event with the detail of the change. The parent component listens for this event and handles it accordingly.
Option A is the correct method because it creates a new custom event with the detail property containing the new value of passthrough. This event is then dispatched, and the parent component can listen for this event to handle the updated value.
Options B, C, and D are incorrect because they either don't pass any data with the event or they don't use the detail object which is the standard way to pass data with custom events in LWC.
