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.

Static resources are ideal for efficient loading and caching of external files in Visualforce. They allow

bundling and minimizing HTTP requests.

The optimal way to enforce the exclusion of blocked domains for email addresses entered into

Contacts and a custom object is to use a helper class. The class can be called by an Apex trigger on

the Contact object and from the controller of the custom Visualforce page used for the Survey

Response. This centralizes the logic for maintainability and reusability.

The component is designed to be used with another component to provide

AJAX support. When the value of the industry select list changes, the 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.

Use Test.startTest() and Test.stopTest(). These methods ensure asynchronous code runs within test

execution and allows for accurate assertions.

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.

The use of getRecordTypeInfosByDeveloperName is a best practice to handle record types. This

approach avoids the need for SOQL queries, reducing the number of governor limits consumed, and

efficiently retrieves record type Ids by their DeveloperName, which is consistent across all Salesforce

environments.

To resolve the issue of the Visualforce page taking too long to display results or exceeding the view

state limit, the developer should use a StandardSetController or implement SOQL LIMIT in the Apex

controller. This limits the number of records that are processed and displayed at one time, which can

prevent view state errors and improve performance.

Reference: Visualforce Developer Guide - StandardSetController

The transient keyword in Visualforce page controllers marks variables that should not be part of the

view state, which can significantly reduce the size of the view state. This can help avoid view state

limit errors and improve page performance because a smaller view state requires less time to send

to the client.

Use Apex Managed Sharing with an after insert trigger. It allows dynamic record sharing based on

user-defined criteria like the Event_Reviewer_c field.

Use BatchApexErrorEvent for notifications. It's automatically triggered for unhandled exceptions in

batch Apex. No need for manual publishing. External systems can subscribe to this event to receive

notifications.

Bulk-safe triggers use collections to aggregate DML operations. This practice minimizes the number

of DML statements, which is essential for bulk processing.

Custom metadata is best for storing configurable settings. It's deployable, packageable, and

upgradeable. Allows different configurations for different instances.

The <apex:actionStatus> tag in Visualforce is used to display the status of an AJAX request, such as showing different text while a command button is processing an action. Reference: Visualforce Developer Guide - apex:actionStatus

To make the test pass, @isTest(SeeAllData=true) should be used to allow the test to access historical

data from the org. This is required because field history tracking data is not copied to a test context,

so you need to allow the test to access live data to assert against it.

Reference: Apex Developer Guide - IsTest Annotation

The correct order in tests with callouts is Test.startTest(), then Test.setMock(), followed by the

method invocation, and finally Test.stopTest(). This ensures the mock callout is used.

Reference: Apex Developer Guide - Testing HTTP Callouts

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.

Salesforce CLI with Salesforce DX is the best tool for managing a source-driven deployment process.

It facilitates version control, scriptable deployment, and rollback, and is optimized for collaboration

and continuous integration.

To make the Aura component responsive, the developer should set multipleRows="true" to allow the

layout items to wrap onto multiple rows on smaller devices. Additionally, setting the size attribute for

different device sizes ensures that the layout adapts to the screen width.

The correct SOQL query to retrieve all fields for a specific Account is to use the FIELDS(ALL) function

within the SELECT clause of the SOQL query. This will return all fields for the Account named 'Acme'.
