질문 # 31
Which three statements are true regarding event handling in the Salesforce B2B Commerce managed package?
(3 answers)
정답：B,D,E
설명：
Explanation
Three statements that are true regarding event handling in the Salesforce B2B Commerce managed package are:
* Salesforce B2B Commerce relies on a central event channel for communication across various Salesforce B2B Commerce Backbone Views and Models called CCRZ.pubSub. This object allows different components to publish or subscribe to events without being coupled with each other. For example, CCRZ.pubSub.trigger('cartChange') will publish an event named cartChange that can be subscribed by any component that needs to react to it.
* CCRZ.pubSub defines the following three functions which can be used for event handling: trigger, on, and once. The trigger function is used to publish an event with a name and optional arguments. The on function is used to subscribe to an event with a name and a callback function. The once function is similar to on, but it will only execute the callback function once for each event.
* CCRZ.pubSub extends the Backbone.Events JavaScript object. This object provides methods for managing events in Backbone.js, which is a JavaScript framework that provides models, views, collections, and events for building single-page applications. CCRZ.pubSub inherits all the methods and properties of Backbone.Events and adds some custom ones. Salesforce References: B2B Commerce and D2C Commerce Developer Guide, Events, PubSub Class

Which wire adapter should a developer use to retrieve metadata about a specific picklist?
정답：C
설명：
Explanation
To retrieve metadata about a specific picklist, a developer should use the getPicklistValues wire adapter. The getPicklistValues wire adapter imports data from the @salesforce/ui-api module and returns an object that contains information such as the picklist's label, value, default value, validity, and controlling field values.
The getPicklistMetadataValues wire adapter does not exist. The getPicklistMetadata wire adapter does not exist either. The getPicklist wire adapter does not exist either.

질문 # 33
The sizing keys used in the Salesforce B2B Commerce Global APIs five distinct operations. What are three of these operations? (3 answers)
정답：A,B,E
설명：
The sizing keys used in the Salesforce B2B Commerce Global APIs perform five distinct operations. Three of these operations are:
* Refetch data (used on some Logic classes): This operation indicates that the data should be refetched from the database instead of using the cached data. For example, ccrz.ccServiceCart.getCart(ccrz.ccAPI.SZ_REFETCH) will refetch the cart data and refresh the cache.
* Related Query to call (sub queries or direct queries): This operation indicates that the related entities should be retrieved by using sub queries or direct queries. For example, ccrz.ccServiceProduct.getProducts(ccrz.ccAPI.SZ_SUBQUERY) will use sub queries to fetch the related entities for each product, while ccrz.ccServiceProduct.getProducts(ccrz.ccAPI.SZ_DIRECTQUERY) will use direct queries to fetch the related entities separately.
* Object type casting: This operation indicates that the data should be cast to a specific object type. For example, ccrz.ccServiceProduct.getProducts(ccrz.ccAPI.SZ_SOBJECT) will cast the data to sObjects instead of transformed objects.

질문 # 34
What tool can a developer use to investigate errors during development?
정답：B
설명：
Explanation
Browser dev tools are a set of web authoring and debugging tools built into most modern browsers. They allow developers to inspect, edit, and debug the HTML, CSS, JavaScript, and network activity of a web page.
They can also provide useful information about errors, warnings, performance, and accessibility issues.
Browser dev tools are especially helpful for developing and testing Lightning web components, as they can display the component hierarchy, attributes, events, and slots.
The other options are not correct because:
* A. Commerce Diagnostics Event Logging is a feature that enables developers to capture and analyze events that occur during the execution of B2C Commerce code. It can help identify performance bottlenecks, memory leaks, and unexpected behavior. However, it is not a tool that can be used directly by the developer, but rather a service that requires a support request to enable and access.
* B. Checkout Flow Log is a log file that shows the details of the checkout flow execution, such as the input and output parameters, the pipeline steps, and the errors and warnings. It can help troubleshoot issues related to the checkout process, such as payment, shipping, or tax calculation. However, it is not a tool that can be used during development, but rather a log file that can be accessed after the checkout flow has run.
* C. Support cases are requests for assistance from the Salesforce support team. They can help resolve technical issues, provide guidance, or escalate bugs. However, they are not a tool that can be used to investigate errors during development, but rather a communication channel that can be used after the developer has exhausted other resources.

질문 # 35
While in the process of gathering requirements from a customer abouthow they would like to set up their net new storefront checkout experience, a consultant learns that the customer needs the ability to add new shipping and billing addresses during checkout.
Which approach should a developer take to meet this requirement?
정답：B
설명：
To enable the ability to add new shipping and billing addresses during checkout, a developer should enable Buyer Managed Contact Point Addresses within the Shipping Address standard component in the Checkout subflow. The Buyer Managed Contact Point Addresses is a feature that allows customers to add, edit, or delete their shipping andbilling addresses during checkout. The developer can enable this feature by setting the buyerManagedContactPointAddressesEnabled attribute to true in the Shipping Address standard component in the Checkout subflow.The Shipping Address standard component is a component that displays and collects the shipping address information for the cart or order. The Checkout subflow is a subflow that defines the steps and components for the checkout process in the storefront. Creating a new shipping address checkout subflow that utilizes the Buyer Managed Contact Point Addresses component is not a valid way to enable this feature, as there is no such component as Buyer Managed Contact Point Addresses. Enabling Buyer Managed Contact Point Addresses within Commerce Administration is not a valid way either, as this feature is not configurable in Commerce Administration. Creating a Lightning web component that enables this functionality and replaces the current shipping address screen within the Checkout subflow is not a valid way either, as this is unnecessary and complicated when there is already a standard component that supports this feature.
