B2B-Commerce-Developer Sample Questions Answers

To introduce new screen behavior in a checkout flow step, a developer should clone the appropriate subflow and replace the Lightning web components in it. A subflow is a reusable flow that can be invoked from another flow as an element. A checkout flow is a flow that defines the steps and components for the checkout process in the storefront. A checkout flow consists of several subflows, each of which corresponds to a checkout step, such as Cart, Shipping Address, Payment, or Order Summary. To introduce new screen behavior in a checkout flow step, a developer should clone the subflow that matches the checkout step they want to modify and replace the Lightning web components in the cloned subflow with their custom components. The developer can then update the checkoutSteps.xml file to point to the cloned subflow instead of the original subflow. Modifying the property mappings in checkoutSteps.xml is not a valid way to introduce new screen behavior in a checkout flow step, as it only affects how data is passed between subflows, not how screens are displayed or rendered. Editing the default subflow directly is not a valid way either, as it can cause conflicts or errors with other stores or environments that use the same default subflow. Adjusting next-state in previous subflow configuration is not a valid way either, as it only affects how subflows are transitioned or navigated, not how screens are displayed or rendered.

To bring some historical data into an org, the data must reside in the org, but cannot be populated in standard or custom objects, and the customer is fine with developers building UI components to surface this data on a case-by-case basis, the option that allows a developer to meet all of these requirements is big objects. Big objects are a type of object that can store and manage massive amounts of data on the Salesforce platform. Big objects can store up to billions of records and are accessible through a subset of SOQL or custom user interfaces. Big objects are not subject to the same storage limits or performance issues as standard or custom objects and are suitable for storing historical or archived data that does not need to be updated frequently. Big objects can be defined using Metadata API or declaratively in Setup. Lightning Canvas is not an option that allows a developer to meet all of these requirements, as it is a framework that allows developers to integrate third-party applications into Salesforce. Lightning Canvas does not store data in the org, but rather displays data from external sources using an iframe. External objects are not an option either, as they are a type of object that map to data stored outside Salesforce. External objects do not store data in the org, but rather access data from external systems using OData services. Lightning Out is not an option either, as it is a feature that allows developers to use Lightning components outside Salesforce. Lightning Out does not store data in the org, but rather renders components on external web pages or applications.

When services use the ccServiceDao class to execute queries, variables are bound by string substitution. This means that the query string contains placeholders for variables that are replaced by their values at runtime. For example, ccrz.ccServiceDao.getQuery('SELECT Id FROM Account WHERE Name = :name') will replace :name with the value of the name variable.

The correct syntax for looping through a series of child components which are tiles is option A. Option A uses the for:each directive to iterate over a collection of items and render a template block for each item. The for:each directive requires an expression that evaluates to an array or an iterable object and an item alias that represents the current item in the iteration. The item alias can be used to access the item’s properties or pass them to child components. In option A, the expression is appTiles, which is an array of objects that represent app tiles, and the item alias is appTile, which represents the current app tile object in the iteration. The appTile object’s properties, such as name, description, and icon, are passed to the app-tile child component using attributes. Option B is incorrect because it uses an invalid syntax for the for:each directive. The for:each directive requires a colon (:) after the for keyword, not an equal sign (=). Option C is incorrect because it uses an invalid syntax for the for:each directive. The for:each directive requires an item alias that represents the current item in the iteration, not a key alias that represents the current index in the iteration. Option D is incorrect because it uses an invalid syntax for the template tag. The template tag requires a closing tag (), not a self-closing tag (
