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.

<template>

<h1>{welcomeHeader}</h1>

</template>

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.

In the context of Salesforce debug logs, code units represent discrete units of work within a transaction. Apex classes (B), Web service invocations (C), and Workflow invocations (E) are considered code units as they encapsulate specific operations or sets of logic that can be executed as part of a transaction. Validation rules (A) and the loading of Lightning components (D) are not considered discrete units of work in the same way, as they are part of the declarative interface and front-end framework, respectively. For more details on how Salesforce handles transactions and debug logs, refer to the Salesforce Developer Documentation:Salesforce Developer Documentation on Transactions and Debug Logs.

To handle the subscription lifecycle of a message channel in a Lightning web component, the developer should implement the subscribe() and unsubscribe() methods from the lightning/messageService module. The subscribe() method returns a subscription object that represents the connection to the message channel. The developer can use this object to unsubscribe from the message channel later. The unsubscribe() method takes a subscription object as a parameter and removes the listener from the message channel. The developer should call the unsubscribe() method when the component is disconnected from the DOM, such as in the disconnectedCallback() lifecycle hook, to avoid memory leaks and performance issues.

The other options are not correct because:

• B. stopListener() is not a valid method for handling the subscription lifecycle of a message channel. There is no such method in the lightning/messageService module or the Lightning web component framework.
• C. startListener() is not a valid method for handling the subscription lifecycle of a message channel. There is no such method in the lightning/messageService module or the Lightning web component framework.

To verify changes by using an external service, a developer can use either of these two ways:

• Create an Apex class that implements the sfdc_checkout.CartShippingCharges interface and defines the getShippingCharges method. This method takes a Cart object as an input parameter and returns a list of CartDeliveryGroupMethod objects with the updated shipping charges. The developer then needs to register the Apex class as the Shipping Calculation Integration in the store administration. This way, the store can call the external service to calculate the shipping charges for each delivery group in the cart.
• Create an Apex class that defines a method to retrieve the shipping charges from an external service and update the Cart Delivery Group Method object. The developer then needs to invoke this method from a trigger on the Cart Delivery Group Method object. This way, the store can update the shipping charges whenever the delivery group method is inserted or updated.

The other options are not valid ways to verify changes by using an external service. Creating a flow using an action is not supported for B2B Commerce, and creating a trigger on the Cart Delivery Group object will not update the shipping charges for each delivery group method. References:

Two different types of services that Salesforce B2B Commerce APIs leverage are:

• Logic services which are responsible for implementing business logic associated with entities. These services are defined in the logic classes, such as ccrz.ccLogicCart, ccrz.ccLogicOrder, or ccrz.ccLogicProduct. These classes provide methods for validating inputs, performing calculations, applying rules, or updating data for each entity.
• Data services which are responsible for querying and transforming data from entities. These services are defined in the service classes, such as ccrz.ccServiceCart, ccrz.ccServiceOrder, or ccrz.ccServiceProduct. These classes provide methods for creating, reading, updating, and deleting data for each entity. Salesforce References: B2B Commerce and D2C Commerce Developer Guide, Service Classes, Logic Classes

To modify the out-of-the-box checkout flow template in Salesforce B2B Commerce, a developer should clone the existing template, make the necessary modifications, activate the modified template, and then reference it in the Experience Builder. This approach ensures that the original template remains intact and provides a fallback option. Salesforce documentation on customizing the checkout flow in B2B Commerce emphasizes the importance of using the Experience Builder for such customizations, providing a visual interface to manage and reference different checkout flow templates.

 To pass HTML from a parent component to a child component, the child component needs to have a  element in its template. A slot is a placeholder for markup that a parent component passes into a component’s body. Slots are part of the Web Component specification. The parent component can use the slot name or the default slot to specify which HTML content goes into which slot of the child component. The other options are not valid elements for passing HTML from parent to child. References:

The display of CC Menu Items can be customized for different users by using the cc_hk_Menu extension to post-process any cached menu items. This extension allows modifying the menu items based on the user context, such as the user role, account, or cart. For example, the extension can hide or show certain menu items based on the user’s permissions or preferences.
