質問 # 80
A developer is trying to integrate a new shipping provider to use during checkout in a storefront Which two steps must the developer take to make an integration available for selection?
正解：B、D
解説：
Explanation
To make an integration available for selection, a developer must create a RegisteredExternalService record using Workbench and create an Apex class that uses the integration framework. Creating a RegisteredExternalService record using Workbench allows the developer to register their custom integration class as an external service in Salesforce B2B Commerce. The RegisteredExternalService record contains information such as the class name, version, display name, description, and category of the integration class.
The category determines where and how the integration class can be used in B2B Commerce, such as ShippingService or TaxService. Creating an Apex class that uses the integration framework allows the developer to define custom logic for integrating with an external service provider's API or service. The integration framework provides interfaces and classes for various types of integrations, such as shipping, tax, payment, inventory, and freight. The developer can implement these interfaces and classes in their custom Apex class and override their methods with their own logic. Modifying the StoreIntegratedService to map to an Apex class ID using Workbench is not a required step for making an integration available for selection, as it is only used for registering internal services that are provided by Salesforce B2B Commerce out-of-the-box.
Entering the integration class name and version in store administration is not a required step either, as it is only used for selecting an existing integration class that has already been registered as an external service.

質問 # 81
A developer needs to implement a business rule around shipping: Anything over a certain amount must be sent through freight at a fixed cost and cannot be sent through standard shipping channels. Which two considerations should the developer consider?
正解：C、D
解説：
* The correct answer is A and D. To implement a business rule around shipping, the developer will need to create a class that implements the sfdc_commerce.CartShippingCharges interface and may need to contain logical branching to handle different scenarios12. The sfdc_commerce.CartShippingCharges interface is a standard interface that defines the methods for calculating shipping charges for a cart1. The developer can use this interface to override the default shipping logic and apply custom rules based on the cart amount or other factors12. The developer may also need to use conditional statements or other logic to determine when to use freight shipping or standard shipping3.
* The implementing class cannot call out to another service and a class will need to implement the sfdc_checkout.CartShippingCharges interface are not the correct answers. The implementing class can call out to another service if needed, such as an external shipping service or a pricing engine2. The sfdc_checkout.CartShippingCharges interface is a deprecated interface that was used for calculating shipping charges for a cart only1. It has been replaced by the sfdc_commerce.CartShippingCharges interface, which supports both carts and orders1. References:

質問 # 83
A developer is on a tight timeline and needs to implement a Lightning web component which can read, create and modify single records. What is the recommended path forward?
正解：D
解説：
To implement a Lightning web component which can read, create and modify single records, the recommended path forward is to use Lightning Data Service. Lightning Data Service is a service that provides access to Salesforce data and metadata, cache management, and data synchronization across components.
Lightning Data Service allows developers to use standard components or base componentsto perform CRUD (create, read, update, delete) operations on single records without writing Apex code or SOQL queries.
Lightning Data Service also handles data caching, performance optimization, and conflict resolution automatically. Using base components is not a sufficient way to implement a Lightning web component which can read, create and modify single records, as base components are only user interface elements that do not provide data access or manipulation functionality by themselves. Base components need to be used with Lightning Data Service or other services to perform CRUD operations on single records. Writing custom functions against a wire adapter is not a recommended way to implement a Lightning web component which can read, create and modify single records, as it involves writing complex and error-prone JavaScript code that may not be efficient or scalable. Writing custom functions against a wire adapter also requires handling data caching, performance optimization, and conflict resolution manually. Creating an Apex controller is not a recommended way either, as it involves writing Apex code that may not be necessary or optimal for performing CRUD operations on single records. Creating an Apex controller also requires exposing Apex methods using @AuraEnabled or @RemoteAction annotations and invoking them from JavaScript code using imperative calls or promises.

質問 # 84
During checkout flow customizations, a developer receives an error on shipping cost calculation integrations with the error code: INSUFFICIENT_ACCESS_OR_READONLY.
What is causing this error?
正解：C
解説：
The error code INSUFFICIENT_ACCESS_OR_READONLY is caused by the cart being no longer in a valid Checkout State during checkout flow customizations. A cart is an object that represents a collection of products and charges that a customer intends to purchase in the storefront. A cart has a Checkout State field that indicates the current state of the checkout process for the cart. The Checkout State can have values such as Draft, InProgress, Completed, or Cancelled. A cart can only be modified or updated when it is in Draft or InProgress state. A cart cannot be modified or updated when it is in Completed or Cancelled state. If an attempt is made to modify or update a cart that is in Completed or Cancelled state, an error with the code INSUFFICIENT_ACCESS_OR_READONLY will be thrown. This error means that the user does not have permission to edit or delete a record because it is read-only or locked. The storefront user does not have access to the Cart Delivery Method object is not a cause of this error code, as it is not related to the cart checkout state or data modification. The Cart Delivery Method object is an object that stores information about the delivery method selected for a cart in the storefront. An error has occurred during the cart shipping charge integration is not a cause of this error code either, as it is not related to the cart checkout state or data modification. The cart shipping charge integration is an integration that calculates and applies shipping charges to a cart based on various factors such as delivery method, location, weight, volume, etc. The storefront user does not have access to custom fields on the Order Delivery Method object is not a cause of this error code either, as it is not related to the cart checkout state or data modification. The Order Delivery Method object is an object that stores information about the delivery method selected for an order summary in the storefront.
