A community page has a custom Apex action that retrieves a list of orders and calculates the total amount for each order. The calculation is complex and takes several seconds, causing the page to time out. Which approach should the developer take to improve the user experience?

Return all orders and perform the calculation client-side in JavaScript.

Use a static resource to pre-calculate the totals and reference them in the component.

Increase the Apex timeout by setting a higher limit in the action.

Use asynchronous processing (e.g., @Future or Queueable) to perform the calculation and notify the user when complete.

A community page displays a list of cases with the case number, subject, and status. The SOQL query currently retrieves all fields from the Case object and also queries the Contact and Account relationships for each case. The page is slow. Which SOQL optimization would have the most impact?

Use a dynamic SOQL query to build the query string at runtime.

Use the WITH SECURITY_ENFORCED clause to ensure field-level security.

Add an ORDER BY on the CreatedDate field to sort the results.

Select only the fields needed (CaseNumber, Subject, Status) and use a subquery to get related Contact and Account names.
