NEW QUESTION # 112
A developer is writing a Jest test for a Lightning web component that conditionally displays child components based on a user's checkbox selections.
What should the developer do to properly test that the correct components display and hide for each scenario?
Answer: B
Explanation:
To ensure that the DOM is clean before each test runs, the developer should use the afterEach() method to reset it. This is part of the setup and teardown process in Jest tests, which helps to avoid state leakage between tests. Reference:
Jest Globals afterEach
NEW QUESTION # 113
An Apex trigger creates an order co record every time an Opportunity is won by a Sales Rep. Recently the trigger is creating two orders.
What is the optimal technique for 2 developer to troubleshoot this?
Answer: D
Explanation:
To troubleshoot the issue of a trigger creating two order records, adding System.debug() statements in the trigger and analyzing the log output in the Developer Console is an effective technique. This will help identify if the trigger is being called more than once or if there is another automation (such as a flow or workflow) causing the additional record creation.
NEW QUESTION # 114
Universal Containers uses a custom Lightning page to provide a mechanism to perform a step-by-step wizard search for Accounts. One of the steps in the wizard is to allow the user to input text into a text field, ERF Number_c, that is then used in a query to find matching Accounts.
Which step should be taken to resolve the issue?
Answer: C
Explanation:
If a SOQL query is causing performance issues due to a non-selective query on a large data volume, moving the query to an asynchronous process such as a Batch Apex or Queueable Apex can help resolve the issue. This allows the query to run in the background without affecting the user's experience.

A developer built an Aura component for guests to self-register upon arrival at a front desk kiosk. Now the developer needs to create a component for the utility tray to alert users whenever a guest arrives at the front desk.
What should be used?
Answer: C
Explanation:
Application Events in Aura components are used for communication between components that are not in the same containment hierarchy. An application event to alert users about the arrival of a guest at the front desk is appropriate because it allows any component within the app to listen and respond to the event, regardless of where it is located in the component hierarchy.
