問題 #61
A Salesforce developer is hired by a multi-national company to build a custom Lightning application that shows employees their employment benefits and earned commissions over time. The application must acknowledge and respect the user's locale context for dates, times, numbers, currency, and currency symbols.
When using Aura components, which approach should the developer implement to ensure the Lightning application complies with the user's locale?

A. Use the $Lacale value provider to retrieve the user preferences.
B. Create a Hierarchical custom setting to store user preferences.
C. Use the $Label global value provider.
D. Use the $User global variable to retrieve the user preferences.

答案：A

問題 #62
A Visualforce page contains an industry select list and displays a table of Accounts that have a matching value in their Industry field.

When a user changes the value in the industry select list, the table of Accounts should be automatically updated to show the Accounts associated with the selected industry, What is the optimal way to implement this?

A. Add an <apex:actionFunction> within the <apax:selecList>.
B. Add an <apex:actionFunction> within the <apex:selectOptions>.
C. Add an <apex:actionsupport> within the <apex:selectOptions>.
D. Add an <apex:actionsupport> within the <apex:selecList>.

答案：D

解題說明：
The <apex:actionSupport> component is designed to be used with another component to provide AJAX support. When the value of the industry select list changes, the <apex:actionSupport> can trigger an AJAX request to the server, causing the page to rerender the table of Accounts with the matching industry. This process occurs without a full page refresh, providing a smoother user experience.

問題 #63
A company has an Apex process that makes multiple extensive database operations and web service callouts. The database processes and web services can take a long time to run and must be run sequentially.
How should the developer write this Apex code without running into governor limits and system limitations?

A. Use Apex Scheduler to schedule each process.
B. Use Limits class to stop entire process once governor limits are reached.
C. Use Queueable Apex to chain the jobs to run sequentially.
D. Use multiple 3zutuze methods for each process and callout.

答案：C

問題 #64
Universal Containers develops a Salesforce application that requires frequent interaction with an external REST API.
To avoid duplicating code and improve maintainability, how should they implement the APL integration for code reuse?

A. Create a reusable Apex class for the AFL integration and invoke it from the relevant Apex classes.
B. Include the API integration code directly in each Apex class that requires it.
C. Use a separate Apex class for each API endpoint to encapsulate the integration logic,
D. Store the APT integration code as a static resource and reference it in each Apex class.

答案：A

解題說明：
Creating a reusable Apex class for API integration allows for code encapsulation and maintainability. This class can then be invoked from any other Apex class that requires interaction with the API, preventing code duplication.References: Apex Developer Guide - Apex Classes

問題 #65
Which tag should a developer use to display different text while an <apex:commandButton> is processing an action?

A. <apex:pageMessages>
B. <apex:actionStatus>
C. <apex:actionSupport>
D. <apex:actionPoller>

答案：B

解題說明：
In Visualforce, the <apex:actionStatus> component is specifically designed to provide user feedback during asynchronous (AJAX) operations. When an <apex:commandButton> or <apex:actionSupport> initiates a request to the server, there is a delay while the server processes the logic and returns the updated data. To prevent users from clicking the button multiple times or to simply inform them that the system is working, developers use <apex:actionStatus>.
This tag allows you to define two facets: startText (or a start facet) and stopText (or a stop facet). By linking the status attribute of the <apex:commandButton> to the id of the <apex:actionStatus>, the page will automatically toggle between these states. For example, while the button is processing, the status can display
"Processing..." or a loading spinner, and once the action is complete, it can return to being hidden or display a
"Completed" message.
Option B is used for timed, repeated requests. Option C is for displaying validation or system errors. Option D is used to add AJAX support to other components (like a picklist) but doesn't manage the display state of the request itself. Therefore, <apex:actionStatus> is the standard tool for managing UI state during the request- response lifecycle in Visualforce.
