To ensure that a custom field is available to display on a given page, the Developer needs to override the Service Class that the page uses and update the Service Management in CCAdmin for the given storefront to use this new Service Class. The Service Class is responsible for retrieving and setting data for a given page. The Logic Class is responsible for implementing business logic and validation rules for a given page. Creating a new Service Class or Logic Class is not necessary, as overriding an existing one can achieve the same result.

When migrating aura components to LWC, a developer should consider two guidelines: migrate one component and then determine whether additional effort would make sense and start with simple components that only render UI. Migrating one component and then determining whether additional effort would make sense allows the developer to evaluate the benefits and costs of migration and decide whether to continue or stop. Migrating simple components that only render UI allows the developer to leverage the performance and modern features of LWC without much complexity or dependency on other components or services. Starting with migrating trees of components (components within components) is not a good guideline, as it can introduce more challenges and dependencies that can complicate the migration process. Forcing all developers to write any new components using Lightning web components is not a good guideline either, as it can create inconsistency and confusion among developers and users.

Two statements that are accurate about the Cart Item with a Type of Charge are that it is linked directly to a Cart Id and that it is linked directly to a Catalog Id. A Cart Item with a Type of Charge is a special type of Cart Item that represents an additional charge or fee that is applied to a Cart, such as shipping, handling, or tax. A Cart Item with a Type of Charge is linked directly to a Cart Id, which means that it belongs to a specific Cart and can be retrieved or updated along with other Cart Items. A Cart Item with a Type of Charge is also linked directly to a Catalog Id, which means that it references a specific Catalog that contains the products and prices for the store. A Cart Item with a Type of Charge is not created with the Cart Delivery Group Method after the shipping integration or after the freight integration, as these are not related to the creation of Cart Items. The Cart Delivery Group Method is a method that determines how products are grouped into delivery groups based on their shipping methods and addresses. The shipping integration and the freight integration are integrations that calculate and apply shipping costs and freight charges to a Cart or an Order.

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.

To retrieve metadata about a specific object, a developer should use the getObjectInfo wire adapter. The getObjectInfo wire adapter imports data from the @salesforce/schema module and returns an object that contains information such as the object’s label, key prefix, fields, child relationships, record type infos, and theme. The getObjectMetadata wire adapter does not exist. The getObject wire adapter does not retrieve metadata, but rather returns a record object based on the record ID. The getObjectDescribe wire adapter does not exist either.

A Lightning Web Component (LWC) consists of a minimum of three core files: the template file (.html), the JavaScript file (.js), and the metadata configuration file (.js-meta.xml). These files are essential for defining the structure, functionality, and configuration of the component. For more information, review the Salesforce LWC documentation:Salesforce LWC Documentation.

A target value of lightning__FlowScreen in metadata allows for a Lightning web component to be used in guided user experiences to gather input and to automatically generate configuration properties for the Lightning web component. The lightning__FlowScreen target value specifies that the component can be used on a flow screen, which is a type of flow element that displays information and collects user input in a flow. A flow is a guided user experience that can automate business processes and guide users through screens, actions, and decisions. By using the lightning__FlowScreen target value, the developer can expose their Lightning web component as a custom screen component that can be added to any flow screen. The developer can also use the @api decorator to expose public properties of their Lightning web component as configuration properties that can be set in Flow Builder. Flow Builder is a tool that allows the developer to create and modify flows using a drag-and-drop interface. A target value of lightning__FlowScreen does not allow the Lightning web component to replace standard functionality in flows and subflows or to be dragged onto a page in Lightning App Builder, as these are not related to the flow screen target value.

 According to the Lightning Web Components Developer Guide, Shadow DOM is a standard that encapsulates the internal document object model (DOM) structure of a web component. Encapsulating the DOM gives developers the ability to share a component and protect the component from being manipulated by arbitrary HTML, CSS, and JavaScript. Shadow DOM also provides style and behavior isolation for a web component, which means that the styles and scripts defined inside a component do not affect the rest of the page, and vice versa. Therefore, the purposes of the Shadow DOM in a Lightning web component are to encapsulate the internal DOM structure of a web component (A) and to allow components to be shared while protecting them from being manipulated by arbitrary code (B). The other options are incorrect because Shadow DOM does not allow direct access to the document object model of the component ©, nor does it allow older JavaScript libraries to manipulate the tagging structure (D). References: Lightning Web Components Developer Guide, Understand the Shadow DOM Unit
