168. Frage
In which two ways can events fired from Lightning web components be handled?
Antwort: A,D
Begründung:
Explanation
Two ways that events fired from Lightning web components can be handled are programmatically adding event listeners and attaching handlers to DOM elements. Programmatically adding event listeners is a way of handling events by using JavaScript code to register functions that are invoked when an event occurs. The developer can use methods such as addEventListener or @wire to add event listeners to components or services that fire events. Attaching handlers to DOM elements is a way of handling events by using HTML attributes to bind functions that are invoked when an event occurs. The developer can use attributes such as onclick or onchange to attach handlers to DOM elements that fire events. Adding callbacks to components is not a valid way of handling events fired from Lightning web components, as it is not related to event handling, but rather to asynchronous programming. Listening for all possible events at the document root is not a valid way either, as it is not efficient or recommended for event handling, as it can cause performance issues or conflicts with other event listeners.

169. Frage
A user wants to have a customized experience for adding items to the cart. The user also wants the mini cart module to reflect changes to the state of the cart afterwords. How should this requirement be fulfilled?
Antwort: A
Begründung:
Explanation
To have a customized experience for adding items to the cart and also update the mini cart module, the requirement can be fulfilled by triggering the global "cartChange" event after the Add to Cart Action on the custom button. This event will notify all the components that are listening to it that the cart has changedand they should refresh their data accordingly. The mini cart module is one of these components, so it will update its state based on the new cart data. Salesforce References: B2B Commerce and D2C Commerce Developer Guide, Events
170. Frage
Which two usages of ccLog should be avoided in Salesforce B2B Commerce? (2 answers)
Antwort: B,D
Begründung:
Explanation
You should avoid using ccLog in two scenarios. First, you should avoid using ccLog with System.LoggingLevel.ERROR when passing in a method invocation as the third parameter, such as ccrz.ccLog.log(System.LoggingLevel.ERROR, 'D:something', myCallToGetMessage(pl) ). This is because if an exception occurs within the method invocation, it will not be caught by ccLog and will cause an unhandled exception on the page. Instead, you should use a try-catch block around the method invocation and log the exception separately. Second, you should avoid using ccLog with System.LoggingLevel.DEBUGwhen passing in a large collection or object as the third parameter, such as ccrz.ccLog.log(System.LoggingLevel.DEBUG,
'D:myOrderList', myOrderList), where myOrderList is a list of orders. This is because logging large objects can cause performance issues and consume a lot of heap space. Instead, you should use a loop to log only the relevant fields or properties of the object or collection. You can use ccLog with System.LoggingLevel.WARN when passing in a string as the third parameter, such as ccrz.ccLog.log(System.LoggingLevel.WARN,
'D:something', 'Something unexpected occurred: The data we were expecting for pl was not there,'). This is a valid use case for logging a warning message. You can also use ccLog with System.LoggingLevel.DEBUG when passing in a small object as the third parameter, such as ccrz.ccLog.log(System.LoggingLevel.DEBUG,
'D:myOrder', myOrder), where myOrder is an order object. This is acceptable as long as the object is not too large or complex. Salesforce References: [B2B Commerce Developer Guide: Logging]
171. Frage
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?
Antwort: C
Begründung:
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.

172. Frage
A developer needs to implement specific styling for a standard component on a single page of the B2B Commerce store using an Aura template. The component should use the default style on all other pages How should the developer implement the required changes over multiple instances?
Antwort: A
Begründung:
Explanation
To implement specific styling for a standard component on a single page of the B2B Commerce store using an Aura template, a developer should create a custom theme layout Aura component that imports the custom CSS file and set up the page to use this theme layout. A theme layout is a type of Aura component that defines the header and footer of a page in the storefront. A theme layout can also import custom CSS files from static resources and apply them to the page. A developer can create a custom theme layout Aura component that imports the custom CSS file that contains the specific styling for the standard component and assign it to the page that needs the custom styling. This way, the custom styling will only affect the standard component on that page and not on other pages that use a different theme layout. Using a custom CSS file in a static resource and adding the import using the Edit Head Markup Editor in the Experience Builder is not a valid way to implement specific styling for a standard component on a single page, as it will affect all pages that use the same template. Creating a custom content layout Lightning web component that imports the custom CSS file and setting up the page to use this content layout is not a valid way either, as it will not affect the standard component that is outside of the content layout. Using the Override CSR Editor in the Experience Builder and adding the desired CSS to change the styles is not a valid way either, as it will affect all pages that use the same template.
