Two technologies that can subscribe to the CommerceDiagnosticEvents event are Aura Components and Lightning web components. CommerceDiagnosticEvents is an event that is fired by Salesforce B2B Commerce when an error occurs in the storefront. CommerceDiagnosticEvents contains information about the error, such as error code, error message, error type, and error details. CommerceDiagnosticEvents can be subscribed by other components or services that want to handle or display the error information in different ways. Aura Components are a type of component that can be used to create custom user interfaces for Salesforce apps. Aura Components can subscribe to CommerceDiagnosticEvents using an aura:handler tag in their markup file. The aura:handler tag specifies an event name, an action attribute that defines a controller function to handle the event, and other optional attributes. Lightning web components are another type of component that can be used to create custom user interfaces for Salesforce apps. Lightning web components can subscribe to CommerceDiagnosticEvents using an @wire decorator in their JavaScript file. The @wire decorator specifies an event name, a function name that defines a handler for the event, and other optional parameters. Processes are not a technology that can subscribe to CommerceDiagnosticEvents, as they are not related to user interface development or event handling. Processes are automated workflows that execute actions based on certain criteria or conditions in Salesforce. Streaming API is not a technology that can subscribe to CommerceDiagnosticEvents either, as it is not related to user interface development or event handling. Streaming API is an API that allows applications to receive notifications of data changes in Salesforce in near real-time.

The event that is triggered within Salesforce B2B Commerce whenever a cart’s state changes is cartChange. This event is triggered by the updateCart method of the CCRZ.Cart class, which is responsible for updating the cart data and performing any actions that depend on the cart state, such as applying discounts, taxes, or shipping charges. The event can be used to notify all the components that are listening to it that the cart has changed and they should refresh their data accordingly.

Three actions that are applicable when extending a default Salesforce B2B Commerce page via a page include are:

• Create the VisualForce page you wish to include to the Salesforce B2B Commerce page. This page will contain the custom content or logic that you want to add to the existing page. For example, youcan create a VisualForce page named MyPageInclude that displays some additional information or functionality on the product detail page.
• Create a configuration setting for enabling the page include and assigning the new page include via CC Admin. This setting will specify which page include you want to use for which page and section. For example, you can create a configuration setting named CO.MyPageInclude with the value PDV.BodyIncludeBegin.MyPageInclude, which means you want to use MyPageInclude as the body include begin for the product detail view (PDV) page.
• Build and activate a new configuration cache setting via CC Admin. This action will refresh the cache and apply the changes to the storefront. You need to do this whenever you make any changes to the configuration settings or VisualForce pages. Salesforce References: B2B Commerce and D2C Commerce Developer Guide, Page Includes

Custom labels are text values that can be translated into any language that Salesforce supports. They are useful for displaying language-specific text in Lightning web components. To use custom labels in a LWC, the developer needs to create them in the Setup menu and assign them to a language and a value. Then, the developer can import them in the LWC using the @salesforce/label scoped module. For example, if the developer has a custom label named welcomeHeader, they can import it as follows:

import welcomeHeader from '@salesforce/label/c.welcomeHeader';

Then, they can use it in the HTML template or the JavaScript file of the LWC. For example, in the HTML template, they can use it as follows:

HTMLAI-generated code. Review and use carefully. More info on FAQ.

The custom label will automatically display the translated value based on the user’s language preference. The developer can also use the lightning-formatted-text component to format the custom label value with HTML tags.

The other options are not correct because:

• A. Importing static resources for the text values is not a recommended way to translate text values in a LWC. Static resources are files that are stored in Salesforce and can be referenced by applications. They are not designed for storing language-specific text values and they do not support automatic translation based on the user’s language preference.
• B. Using a CustomLabel xml file in the LWC to add the text values there is not a valid option. Custom labels are not stored in xml files, but in the Setup menu. They cannot be added directly to the LWC, but they need to be imported using the @salesforce/label scoped module.
• D. Creating a custom Metadata object for the text values and querying it in the LWC is not a feasible option. Custom Metadata objects are records that store configuration data that can be deployed and packaged. They are not intended for storing language-specific text values and they do not support automatic translation based on the user’s language preference. Querying them in the LWC would also require an Apex class and a wire service, which would add unnecessary complexity to the solution.
