Question No. 1

How can a developer introduce new screen behavior in a checkout flow step?

Show Answer Hide Answer
Correct Answer: D

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.

Question No. 2

A developer needs to import some new product data contained in a JSON file one time. What are two viable ways to do this? .

Show Answer Hide Answer
Correct Answer: B, C

Two viable ways that a developer can import some new product data contained in a JSON file one time are running a command like: sfdx force:data:tree:import -f NewProducts.json -u <your username> and converting the JSON to a CSV file and using Data Loader to import it. Running a command like: sfdx force:data:tree:import -f NewProducts.json -u <your username> allows the developer to import data from a JSON file into an org using Salesforce CLI commands. The sfdx force:data:tree:import command is a Salesforce CLI command that imports data into an org using JSON files that conform to the SObject Tree API specification. The SObject Tree API specification is a format that defines how records are represented in JSON files for data import or export. The -f flag specifies the path of the JSON file that contains the data to be imported. The -u flag specifies the username or alias of the org where the data will be imported. Running this command will create records in the org based on the data in the JSON file. Converting the JSON to a CSV file and using Data Loader to import it allows the developer to import data from a CSV file into an org using Data Loader. Data Loader is a tool that allows users to import or export data between Salesforce and CSV files. The developer can use an online converter or a spreadsheet application to convert their JSON file into a CSV file that matches the structure and format of their Salesforce object. The developer can then use Data Loader to import the CSV file into their org and create records based on the data in the CSV file. Converting the JSON to an xlsx file and using Workbench to import it is not a viable way to import some new product data contained in a JSON file one time, as Workbench does not support xlsx files for data import or export. Workbench is a web-based tool that provides access to various Salesforce features and functionalities, such as data manipulation, REST Explorer, and Apex Execute. Running a command like: sfdx force:data;import:bulk -f NewProducts.json -u <your username> is not a viable way either, as there is no such command as sfdx force:data;import:bulk. The correct command for importing data using bulk API is sfdx force:data:bulk:upsert.

Question No. 4

A developer needs to implement a custom Lightning web component (LWC) for the storefront.

The LWC contains language-specific text values.

How should the developer translate the text values?

Show Answer Hide Answer
Correct Answer: C

Custom labels are text values that can be translated into any language that Salesforce supports. They are useful for displaying language-specific text in Lightning web components. To use custom labels in a LWC, the developer needs to create them in the Setup menu and assign them to a language and a value. Then, the developer can import them in the LWC using the@salesforce/labelscoped module. For example, if the developer has a custom label namedwelcomeHeader, they can import it as follows:

import welcomeHeader from '@salesforce/label/c.welcomeHeader';

Then, they can use it in the HTML template or the JavaScript file of the LWC. For example, in the HTML template, they can use it as follows:

HTMLAI-generated code. Review and use carefully.More info on FAQ.

<template>

<h1>{welcomeHeader}</h1>

</template>

The custom label will automatically display the translated value based on the user's language preference. The developer can also use thelightning-formatted-textcomponent to format the custom label value with HTML tags.

The other options are not correct because:

A) Importing static resources for the text values is not a recommended way to translate text values in a LWC. Static resources are files that are stored in Salesforce and can be referenced by applications. They are not designed for storing language-specific text values and they do not support automatic translation based on the user's language preference.

B) Using a CustomLabel xml file in the LWC to add the text values there is not a valid option. Custom labels are not stored in xml files, but in the Setup menu. They cannot be added directly to the LWC, but they need to be imported using the@salesforce/labelscoped module.

D) Creating a custom Metadata object for the text values and querying it in the LWC is not a feasible option. Custom Metadata objects are records that store configuration data that can be deployed and packaged. They are not intended for storing language-specific text values and they do not support automatic translation based on the user's language preference. Querying them in the LWC would also require an Apex class and a wire service, which would add unnecessary complexity to the solution.

Question No. 5

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

Show Answer Hide Answer
Correct Answer: A, D

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.
