B2B-Commerce-Developer Practice Test Questions

Explanation:

The lightning-record-edit-form component allows a developer to view or edit a record while maintaining control over specifying its layout and set of fields. This component provides a way to create forms that respect the field-level security and layout configuration defined in the Salesforce metadata. The developer can use lightning-inputfield components inside the form to display and edit the fields of a record. The other options are incorrect because they either do not allow editing the record, do not respect the metadata configuration, or do not exist as valid component paths.

Explanation:

In Lightning Web Components, to access the DOM elements within the component's template, including those passed into slots, developers use this.template.querySelector()andthis.template.querySelectorAll(). These methods allow for querying the component's local DOM. Direct DOM manipulation or querying outside the component's template is discouraged to maintain component encapsulation and security. For more information, see the Salesforce LWC documentation on accessing the DOM:Salesforce LWC DOM Access Documentation.

Explanation:

When creating a custom Lightning Web Component (LWC) for use in the Checkout Flow, a developer must set the target in the js-meta.xml file to lwc__FlowComponent. This target specifies that the LWC is intended for use within the flow component framework, allowing it to be utilized specifically in the context of Salesforce Flows, including those used in the checkout process. Salesforce documentation on developing custom LWCs for various targets would detail this requirement, ensuring that developers understand how to correctly package and deploy their components for the intended use case.

Explanation:

The correct answer is A and D. To implement a business rule around shipping, the developer will need to create a class that implements the sfdc_commerce.CartShippingCharges interface and may need to contain logical branching to handle different scenarios12.

The sfdc_commerce.CartShippingCharges interface is a standard interface that defines the methods for calculating shipping charges for a cart1. The developer can use this interface to override the default shipping logic and apply custom rules based on the cart amount or other factors12. The developer may also need to use conditional statements or other logic to determine when to use freight shipping or standard shipping3.

The implementing class cannot call out to another service and a class will need to implement the sfdc_checkout.CartShippingCharges interface are not the correct answers. The implementing class can call out to another service if needed, such as an external shipping service or a pricing engine2.

The sfdc_checkout.CartShippingCharges interface is a deprecated interface that was used for calculating shipping charges for a cart only1. It has been replaced by the sfdc_commerce.CartShippingCharges interface, which supports both carts and orders1.

Explanation:

The developer forgot to publish the storefront after making changes to the products. Publishing the storefront is a necessary step to make the changes visible to the store visitors. Publishing the storefront updates the site’s metadata and content, and also triggers the site index and search index rebuilds. If the developer does not publish the storefront, the changes will not be reflected on the live site.

The following actions are not required or relevant for the scenario:

Activate the product list. This action is only needed when creating a new product list or modifying an existing one. It does not affect the visibility of the products on the storefront.

Rebuild the search index. This action is automatically performed when the developer publishes the storefront. It is not a separate step that the developer needs to take manually.

Publish the catalog. This action is not applicable for Salesforce B2B Commerce for Visualforce, which does not use catalogs. Catalogs are only used by Salesforce B2B Commerce for Lightning Experience.

Explanation:

The default Global API Data-Sizing convention flag that is used by the API’s unless otherwise specified is CCRZ.ccAPI.SZ_M. This flag indicates that the medium sizing block should be used for retrieving data, which includes the most commonly used fields and related entities. For example, ccrz.ccServiceProduct.getProducts() will use the SZ_M sizing block by default, unless another sizing block is specified as a parameter.

Explanation:

If a developer leaves debug mode turned on in an environment, the user will begin getting JavaScript limit exceptions. Debug mode is a setting that enables more detailed logging and error reporting for Lightning web components. However, it also increases the size and complexity of the JavaScript code that is delivered to the browser, which can cause performance issues and JavaScript limit exceptions. The JavaScript limit exceptions are errors that occur when the browser reaches its maximum capacity for executing JavaScript code, such as memory heap size or script execution time. The performance of the org will not become slower each day, as debug mode only affects the client-side performance, not the server-side performance. The org will not turn off debug mode after 72 hours, as debug mode is a persistent setting that can only be changed manually by an administrator. A banner will not be displayed to the userindicating that the org is in debug mode, as debug mode is a transparent setting that does not affect the user interface.Explanation:Explanation:

^Explanation:

To implement a custom Terms and Conditions checkbox at checkout in the Aura Commerce template, a developer should add a Desired Delivery Date input field during the checkout flow. The Desired Delivery Date input field allows the customer to enter a date when they want their order to be delivered. The developer can use the @api decorator to expose this field as a public property of the Lightning web component and bind it to the ccCheckoutOrder object. The developer can also use the @wire decorator to get the current cart object and use its properties, such as shipping address and shipping method, to calculate and display an estimated delivery date based on the desired delivery date. The developer can also add validation logic to ensure that the desired delivery date is valid and acceptable. Adding the Expected Delivery Date field to the order confirmation email is not a good solution, as it does not allow the customer to choose or see their delivery date before placing their order. Displaying the Expected Delivery Date on the order page with a Lightning web component is not a good solution either, as it does not allow the customer to enter or change their delivery date after placing their order. Configuring an email alert to the customer when the Expected Delivery Date changes is not a good solution either, as it does not provide a consistent or reliable way of informing the customer about their delivery date.

Explanation:

When implementing code for external pricing comparisons, if the external prices are the same as the sales prices for products in the cart, the implementation should ideally return a status indicating success (such as sfdc_checkout.IntegrationStatus.Status.SUCCESS). This indicates that the external pricing verification has passed and there are no discrepancies between the external and sales prices.

Explanation:

To leverage a three column layout on a page and move the mini-cart widget from the right to the center column, the requirement can be fulfilled by creating a Gross Layout Override. This is a custom Visualforce page that overrides the default layout of a page and allows changing its structure and content. The user can create a Gross Layout Override that uses a three column layout and places the mini-cart widget in the center column.
