B2B-Commerce-Developer Practice Test

Explanation:

In Salesforce Experience Cloud, components like CMS Collection and Results Layout are designed to be reusable across different Experience templates, not just limited to B2B Commerce. CMS Collection allows for the display of CMS content in a flexible and dynamic layout, while Results Layout can be used to present search or query results in a customizable format. Salesforce documentation on Experience Cloud components emphasizes the reusability and adaptability of these components across various templates and contexts.

Explanation:

To override pricing during the checkout process in Salesforce B2B Commerce, a developer must implement a class specifically designed for this purpose, such assfdc_checkout.CartPriceCalculations. This class would provide the necessary framework for custom pricing logic to be applied during checkout, ensuring that any custom pricing requirements are met.

Explanation:

When a developer configures a tax integration for a store, the previously calculated tax entries during the checkout flow are deleted from the Cart. A tax integration is an integration that calculates and applies tax rates and amounts to a Cart or an Order based on various factors, such as product type, price, quantity, location, and tax rules. A tax integration can use either an external tax service provider or custom Apex code to perform the tax calculation. When a developer configures a tax integration for a store, any existing tax entries in the Cart are deleted before calling the tax integration service or method. This ensures that the tax calculation is accurate and up-to-date based on the current state of the Cart and avoids any conflicts or inconsistencies with previous tax entries. The previously calculated tax entries are not ignored during recalculation, saved prior to recalculation, or modified with the new tax calculation, as these are not valid actions for handling existing tax entries.

Explanation:

The connectedCallback is a lifecycle hook that is invoked when a Lightning web component is inserted into the DOM. It is used to perform any initialization tasks that depend on the component being rendered, such as fetching data, setting up event listeners, or creating timers. The connectedCallback can fire more than once, for example, when a component is moved or rerendered. The connectedCallback should not be used to change the state of a component, such as loading values or setting properties. Use getters and setters instead. The other options are incorrect because they do not describe the purpose of the connectedCallback.

Explanation:

Composition is a key pattern in building Lightning Web Components (LWCs). This approach involves creating small, reusable components that can be assembled to form more complex interfaces. This pattern promotes modularity, reusability, and maintainability in the development of web components, aligning with web standards and best practices.
