C.    Combines and de-duplicates server calls

D.   Loads record data progressively

Explanation:

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.

D.   view:*:rendered

Explanation:

The event that is invoked by any CCRZ Salesforce B2B Commerce View after the view is rendered is view:*:rendered. This event is triggered by the render method of the CCRZ.View class, which is the base class for all views in the framework. The event can be used to perform any actions or logic that depend on the view being rendered, such as initializing widgets, binding events, or updating the user interface.

A.   When different entities are specified in the method invocation.

C.   SZ_ASSC is used.

E.   SZ_ASSC is not used.

Explanation:

Salesforce B2B Commerce API sizing blocks can support multiple API sizing requests in three ways:

When different entities are specified in the method invocation. For example, ccrz.ccServiceProduct.getProducts(ccrz.ccAPI.SZ_M, ccrz.ccAPI.SZ_L) will use the SZ_M sizing block for the product entity and the SZ_L sizing block for the related entities.

SZ_ASSC is used. This flag indicates that the associated entities should use the same sizing block as the primary entity. For example, ccrz.ccServiceProduct.getProducts(ccrz.ccAPI.SZ_M, ccrz.ccAPI.SZ_ASSC) will use the SZ_M sizing block for both the product entity and the related entities.

SZ_ASSC is not used. This flag indicates that the associated entities should use the default sizing block, which is SZ_M, unless otherwise specified. For example, ccrz.ccServiceProduct.getProducts(ccrz.ccAPI.SZ_M) will use the SZ_M sizing block for the product entity and the SZ_M sizing block for the related entities.

A.   Create a named credential for authentication with the payment provider.

C.   Create an Apex class that implements the sfdc_checkout.PaymentGatewayAdapter

D.    Create a PaymentProviderGateway record for the custom payment provider class.

Explanation:

Three actions that a developer must take, in a B2B Commerce store, to accept credit card payments using a client’s chosen payment provider are: create a named credential for authentication with the payment provider, create an Apex class that implements the sfdc_checkout.PaymentGatewayAdapter interface, and create a PaymentProviderGateway record for the custom payment provider class. Creating a named credential for authentication with the payment provider allows the developer to securely store and manage authentication information, such as username, password, token, or certificate, for connecting to the payment provider’s API or service. Creating an Apex class that implements the sfdc_checkout.PaymentGatewayAdapter interface allows the developer to define custom logic for processing credit card payments using the payment provider’s API or service. The interface provides methods for validating credit card information, authorizing payments, capturing payments, voiding payments, and refunding payments. Creating a PaymentProviderGateway record for the custom payment provider class allows the developer to register the custom payment provider class as a payment gateway in the store and associate it with a payment method.

Creating a RegisteredExternalService record for the custom payment provider class is not a required action, as this is only used for registering external services that are not related to payment processing, such as tax or shipping services. Creating an Apex class that implements the commercepayments.PaymentGatewayAdapter interface is not a required action either, as this is only used for D2C Commerce stores, not B2B Commerce stores.

A.   An Aura component can contain another Aura component

B.   An Aura component can contain a Lightning Web Component

D.   A Lightning Web Component cannot contain an Aura component

Explanation:

Salesforce documentation clarifies the interoperability between Aura and Lightning Web Components (LWCs). An Aura component can indeed contain another Aura component, as well as a LWC, allowing for a mix of component technologies in a single application. However, due to the architectural and design principles of LWCs, a LWC cannot contain an Aura component. This is because LWCs are designed to be lightweight and leverage web standards, which makes them not fully compatible with the older Aura component framework in terms of containment.
