Question 146

The sizing keys used in the Salesforce B2B Commerce Global APIs five distinct operations. What are three of these operations? (3 answers)

Correct Answer: A,D,E
Explanation
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.

Question 147

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?

Correct Answer: C
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.

Question 148

A Developer created a custom field that a project wants to expose on a given page.
How does the Developer ensure that the field is available to display on a given page?

Correct Answer: A
To ensure that a custom field is available to display on a given page, the Developer needs to override the Service Class that the page uses and update the Service Management in CCAdmin for the given storefront to use this new Service Class. The Service Class is responsible for retrieving and setting data for a given page.
The Logic Class is responsible for implementing business logic and validation rules for a given page. Creating a new Service Class or Logic Class is not necessary, as overriding an existing one can achieve the same result.

Question 149

In which two ways can events fired from Lightning web components be handled?

Correct Answer: A,D
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.

Handle Events], [Lightning Web Components Developer Guide: Communicate with Events]

Question 150

What are two considerations to keep in mind when including additional JavaScript files in a Lightning web component?

Correct Answer: B,C
When including additional JavaScript files in a Lightning web component, a developer should keep in mind two considerations: the files must be ES6 modules and must have names that are unique within the component's folder and a module can export named functions or variables. The files must be ES6 modules because LWC uses ES6 modules as the standard for modular JavaScript code. The files must have names that are unique within the component's folder because LWC uses the file name as the module identifier and does not allow duplicate identifiers. A module can export named functions or variables because LWC supports named exports, which allow a module to export multiple values with different names. Each additional file does not need a corresponding .js-meta.xml file, as this is only required for the main JavaScript file of the component. Additional JavaScript files should not be minified before deployment, asthis is not necessary or recommended for LWC.
