B2B-Commerce-Developer Practice Test

Explanation:

To expose a public property in a Lightning web component, the developer should decorate the field with the @api decorator. This decorator marks the property as public, which means that it can be set by another component, such as a parent component. The @api decorator also makes the property reactive, which means that any changes to the property value are reflected in the component’s template. The other decorators (@property, @track, and @public) are not valid for exposing public properties in Lightning web components.

Explanation:

According to the B2B Commerce Developer Guide, the ICart interface provides access to the cart object and its related data. The Details property of the ICart interface returns an ICartDetails object, which contains information about the cart such as the currency, the subtotal, the shipping cost, the tax, and the grand total. The Fields property of the ICartDetails interface returns a map of field names and values for the cart object. Therefore, to get the grand total amount for items in the cart and in the currency of the cart, a developer should use the expression {ICart.Details.Fields.grandTotal}, which returns the value of the grandTotal field from the cart object.

Explanation:

To import the ID of the current Lightning Experience community, a developer should use the following code statement:

import id from ‘@salesforce/community/Id’; The @salesforce/community module allows the developer to access information about the current community, such as its ID, name, URL, and base path. The other modules do not exist or are not related to the community ID. The @salesforce/network module is used to access information about the current network, such as its ID and name. The @salesforce/experience module is used to access information about the current user experience, such as whether it is standard or custom. The @salesforce/site module is used to access information about the current site, such as its name and prefix.

Explanation:

Three actions that are applicable when modifying the number of steps required in the Salesforce Commerce Checkout flow are:

Perform a template override on the Checkout page. This action will allow you to change the structure and content of the Checkout page, such as adding or removing sections, widgets, or fields. For example, you can override the checkout.handlebars template and modify it according to your requirements. Set the value of the configuration setting defined as CO.overrideFlow to TRUE. This setting will enable you to use your own custom checkout flow instead of the default one. You need to set this value to true before you can modify the checkout flow.

Set the value of the configuration setting defined as CO.useDef to TRUE. This setting will enable you to use a single-page checkout flow instead of a multi-step checkout flow. You need to set this value to true if you want to reduce the number of steps in the checkout flow to one. Salesforce References: B2B Commerce and D2C Commerce Developer Guide, Checkout Flow

Explanation:

Two methods from the platformResourceLoader module that are relevant for including third party JavaScript and CSS in a Lightning web component are loadScript and loadStyle. The platformResourceLoader module is a module that provides methods for loading JavaScript or CSS files from static resources or external URLs into a Lightning web component. The loadScript method is used to load a JavaScript file and execute it in the component. The loadStyle method is used to load a CSS file and apply it to the component. The loadClientScript method does not exist or is not relevant for including third party JavaScript in a Lightning web component. The loadCss method does not exist or is not relevant for including third party CSS in a Lightning web component.
