Two advantages of using Lightning Data Service are that it combines and de-duplicates server calls and that it loads record data progressively. Lightning Data Service is a service that provides access to Salesforce data and metadata in Lightning web components. It optimizes performance and minimizes server round trips by caching data on the client side and sharing data across components. It also combines and de-duplicates server calls by batching requests for the same record or object and returning a single response. It also loads record data progressively by returning available cached data first and then fetching updated data from the server asynchronously. Communicating with other components and converting between different data formats are not advantages of using Lightning Data Service, as they are not related to its functionality or features.

 Executing dynamic SOQL inside a without sharing class with a bind variable from PageReference.getParameters(), PageReference.getCookies(), or cc_RemoteActionContext class will open up a major security hole because these sources of input are not sanitized and can be manipulated by malicious users to inject SOQL queries that bypass the sharing rules and access data that they are not supposed to see. For example, a user can modify the URL parameters or cookies to include a SOQL query that returns sensitive data from the database. To prevent this, it is recommended to use static SOQL or escape the bind variables before executing dynamic SOQL.

• The correct answer is External Objects. External objects are similar to custom objects, except that they map to data that’s stored outside your Salesforce org12. You can use external objects to access data in real time via web service callouts, without copying the data into your org12. External objects are read-only by default, but you can enable write operations for some data sources12.
• Big Objects are not the correct answer. Big objects allow you to store and manage massive amounts of data on the Salesforce platform. However, big objects are not suitable for referencing historical data in another system, as they require importing the data into the org and incur storage costs.
• Lightning Out is not the correct answer. Lightning Out is a feature that lets you run Lightning components in any container outside the Salesforce platform. However, Lightning Out does not provide a way to reference historical data in another system, as it is mainly used for embedding Lightning components in other web pages or apps.
• External SOQL queries in Apex code are not the correct answer. External SOQL queries are a way to query data from external data sources using SOQL syntax in Apex code. However, external SOQL queries require defining an external data source and an external object first, so they are not a product feature by themselves, but rather a way to use external objects in Apex code. References:

Composition is a key pattern in building Lightning Web Components (LWCs). This approach involves creating small, reusable components that can be assembled to form more complex interfaces. This pattern promotes modularity, reusability, and maintainability in the development of web components, aligning with web standards and best practices.

To implement a custom Terms and Conditions checkbox at checkout in the Aura Commerce template, a developer should add a Desired Delivery Date input field during the checkout flow. The Desired Delivery Date input field allows the customer to enter a date when they want their order to be delivered. The developer can use the @api decorator to expose this field as a public property of the Lightning web component and bind it to the ccCheckoutOrder object. The developer can also use the @wire decorator to get the current cart object and use its properties, such as shipping address and shipping method, to calculate and display an estimated delivery date based on the desired delivery date. The developer can also add validation logic to ensure that the desired delivery date is valid and acceptable. Adding the Expected Delivery Date field to the order confirmation email is not a good solution, as it does not allow the customer to choose or see their delivery date before placing their order. Displaying the Expected Delivery Date on the order page with a Lightning web component is not a good solution either, as it does not allow the customer to enter or change their delivery date after placing their order. Configuring an email alert to the customer when the Expected Delivery Date changes is not a good solution either, as it does not provide a consistent or reliable way of informing the customer about their delivery date.

To view the fields available for the Product Detail Page, the developer should type CCRZ.productDetailModel in the Developer Tools Console in the browser. This will display the product detail model object, which contains the product data and attributes that are rendered on the page. The other options are either not valid or not relevant for the Product Detail Page.

To create custom Lightning web components (LWCs), a developer must take two steps: authorize an org for an SFDX project and deploy a custom component. Authorizing an org for an SFDX project allows the developer to connect to a Salesforce org, such as a scratch org, a sandbox, or a production org, and use it as a development environment. Deploying a custom component allows the developer to push the LWC code from the local project to the org and make it available for use. Creating an Apex class is not a required step for creating custom LWCs, as not all LWCs need to use Apex. Cloning an LWC is not a required stepeither, as it is an optional way to create a new LWC based on an existing one.

n: The Commerce Product Data Import resource is the recommended tool for importing products for a B2B or B2C store using a .csv file. This resource supports importing data of related objects, such as ProductCatalog, ProductCategory, Product2, and ProductCategoryProduct, while preserving their relationships. It also does not require additional licenses or third-party tools. The other options are either not specific to Commerce products, or do not support importing data of related objects. References:

• B2B and D2C Commerce Data Model

 To implement the use of a third-party service for either tax, shipping, or pricing calculation in a B2B Commerce store, a developer must complete these three tasks:

• Create an Apex class that implements the appropriate interface for the calculation type. For example, for tax calculation, the developer must implement the sfdc_checkout.CartTax interface and define the getTax method. This method takes a Cart object as an input parameter and returns a list of CartTax objects with the calculated tax amounts.
• Create a named credential for authentication with the external service. A named credential specifies the URL of a callout endpoint and its required authentication parameters. The developer can use the named credential in the Apex class to make the callout to the external service and handle the response.
• Register the Apex class as the integration in the store administration. The developer must specify the Apex class name in the corresponding field for the calculation type. For example, for tax calculation, the developer must enter the Apex class name in the Tax Calculation Integration field. This way, the store can invoke the Apex class to perform the calculation for each cart.

The other options are not valid tasks for implementing the use of a third-party service. Creating a flow to call the external service directly is not supported for B2B Commerce, and creating an Apex class with an invocable method is not required for the calculation integration. References:

In Salesforce Experience Cloud, components like CMS Collection and Results Layout are designed to be reusable across different Experience templates, not just limited to B2B Commerce. CMS Collection allows for the display of CMS content in a flexible and dynamic layout, while Results Layout can be used to present search or query results in a customizable format. Salesforce documentation on Experience Cloud components emphasizes the reusability and adaptability of these components across various templates and contexts.
