A query containing a subquery is executed. What is appended to the subquery name as part of its transformation by default in Salesforce B2B Commerce?


A. A subscriber-supplied token


B. "__ccrz"


C. The "*" symbol


D. The letter "S"





B.   "__ccrz"

Explanation:

A query containing a subquery is executed. By default, in Salesforce B2B Commerce, “__ccrz” is appended to the subquery name as part of its transformation. This is done to avoid conflicts with the standard Salesforce fields and relationships. For example, SELECT Id, Name, (SELECT Id, Name FROMContacts) FROM Account will be transformed to SELECT Id, Name, (SELECT Id, Name FROM Contacts__ccrz) FROM Account__ccrz.

Which category can receive signaling from a Lightning Message Channel?


A. only descendents (i.e. children)


B. only direct siblings


C. page (anywhere on it)


D. only ancestors (i.e. parents)





C.   page (anywhere on it)

Explanation:

A Lightning Message Channel can receive signaling from any component on a page (anywhere on it). A Lightning Message Channel is a service that allows components to communicate with each other across different Salesforce UI technologies, such as Aura, LWC, Visualforce, and Lightning web apps. A component can subscribe to a message channel and receive events that are published by another component on the same or different page. The message channel acts as a mediator that delivers the events to the subscribers. A Lightning Message Channel does not receive signaling only from descendants (i.e., children), only from direct siblings, or only from ancestors (i.e., parents), as these are limitations of event-based communication.

In a B2B Commerce store, which three tasks must a developer complete to implement the use of a third-party service for either tax, shipping, or pricing calculation?


A. Register an Apex class as the integration in the store administration


B. Create a flow to call the external service directly


C. Create an Apex class implementing the appropriate interface.


D. Create a named credential for authentication with an external service


E. Create an Apex class with an invocable method





A.   Register an Apex class as the integration in the store administration

C.   Create an Apex class implementing the appropriate interface.

D.   Create a named credential for authentication with an external service

Explanation:

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.

The ccUtil apex class in Salesforce B2B Commerce provides numerous utility functions that can be leveraged in subscriber classes. What are two ways to check the input or return data of the Global API's? (2 answers)


A. ccrz.ccUtil.isNotEmpty(Map) andccrz.ccUtil.isNotEmpty(List)


B. ccrz.ccUtil.isNotValid(Map) andccrz.ccUtil.isNotValid(List)


C. ccrz.ccUtil.isValid(Map) and ccrz.ccUtil.isValid(List)


D. ccrz.ccUtil.isEmpty(Map) and ccrz.ccUtil.isEmpty(List)





A.   ccrz.ccUtil.isNotEmpty(Map) andccrz.ccUtil.isNotEmpty(List)

D.   ccrz.ccUtil.isEmpty(Map) and ccrz.ccUtil.isEmpty(List)

Explanation:

The ccUtil apex class provides two methods to check the input or return data of the Global API’s: ccrz.ccUtil.isNotEmpty(Map) and ccrz.ccUtil.isEmpty(Map). These methods return true if the map is not null and contains at least one entry, or if the map is null or empty, respectively. Similarly, ccrz.ccUtil.isNotEmpty(List) and ccrz.ccUtil.isEmpty(List) return true if the list is not null and contains at least one element, or if the list is null or empty, respectively. These methods are useful for validating the input parameters or the output results of the Global API’s.

Which three files are required for a deployable Lightning Web Component called displayMyData that will fetch and display data?


A. displayMyData.css


B. displayMyData.js-meta.xml


C. displayMyData.js


D. displayMyDataController.cls


E. displayMyData.html





A.   displayMyData.css

B.   displayMyData.js-meta.xml

E.   displayMyData.html

Explanation:

For a deployable Lightning Web Component likedisplayMyData, the required files include the component's CSS file (displayMyData.css) for styling, the metadata configuration file (displayMyData.js-meta.xml) for defining the component's configuration and properties, and the template file (displayMyData.html) for the component's HTML structure. The JavaScript file (displayMyData.js) contains the business logic but is not listed as an option here. For deployment, these files are essential. Refer to the Salesforce LWC documentation for deployment requirements:Salesforce LWC Deployment Documentation.
