NEW QUESTION # 113
Universal Containers (UC) has enabled the translation workbench and has translated picklist values. UC has a custom multi-select picklist field, Product__c, on the Account object that allows sales reps to specify which of UC's products an Account already has. A developer is tasked with writing an Apex method that retrieves Account records, including the Product_c field.
What should the developer do to ensure the value of Products__c is in the current user's language?
Answer: C
Explanation:
Using toLabel() in the SOQL query ensures that picklist values are returned in the user's language, which is necessary for organizations that have the translation workbench enabled.

NEW QUESTION # 114
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: C
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 # 115
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: C
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:
Platform Events Developer Guide
NEW QUESTION # 116
Refer to the Lightning component below:
The Lightning Component allows users to click a button to save their changes and then redirects them to a different page. Currently when the user hits the Save button, the records are getting saved, but they are not redirected. Which three techniques can a developer use to debug the JavaScript? Choose 3 answers
Answer: A,C,E
Explanation:
When debugging JavaScript in a Lightning Component, developers can utilize the following techniques:
A . Use console.log() messages in the JavaScript: This is a standard debugging technique to log information to the browser console, which can help trace the execution flow or output variable values.
B . Use the browser's dev tools to debug the JavaScript: Modern browsers come equipped with developer tools that can be used to set breakpoints, step through code, and inspect variables at runtime.
C . Enable Debug Mode for Lightning components for the user: Enabling Debug Mode for users provides more detailed error messages and unminified versions of client-side libraries, making it easier to debug issues.
Using the Developer Console to view checkpoints (Option D) and debug logs (Option E) is more relevant for Apex debugging rather than JavaScript.
