Show Answer

Correct Answer: D

The error code INSUFFICIENT_ACCESS_OR_READONLY is caused by the cart being no longer in a valid Checkout State during checkout flow customizations. A cart is an object that represents a collection of products and charges that a customer intends to purchase in the storefront. A cart has a Checkout State field that indicates the current state of the checkout process for the cart. The Checkout State can have values such as Draft, InProgress, Completed, or Cancelled. A cart can only be modified or updated when it is in Draft or InProgress state. A cart cannot be modified or updated when it is in Completed or Cancelled state. If an attempt is made to modify or update a cart that is in Completed or Cancelled state, an error with the code INSUFFICIENT_ACCESS_OR_READONLY will be thrown. This error means that the user does not have permission to edit or delete a record because it is read-only or locked. The storefront user does not have access to the Cart Delivery Method object is not a cause of this error code, as it is not related to the cart checkout state or data modification. The Cart Delivery Method object is an object that stores information about the delivery method selected for a cart in the storefront. An error has occurred during the cart shipping charge integration is not a cause of this error code either, as it is not related to the cart checkout state or data modification. The cart shipping charge integration is an integration that calculates and applies shipping charges to a cart based on various factors such as delivery method, location, weight, volume, etc. The storefront user does not have access to custom fields on the Order Delivery Method object is not a cause of this error code either, as it is not related to the cart checkout state or data modification. The Order Delivery Method object is an object that stores information about the delivery method selected for an order summary in the storefront.

Question No. 2

A developer is working on an existing checkout implementation built against the Lightning Web Runtime (LWR) and wants to implement a custom child checkout component to modify out-of-the-box functionality.

Which interface must the developer implement for the child component?

ACheckoutSavable

BCheckoutoutinterface

CCustomCheckout

DCheckoutStep

Show Answer

Correct Answer: D

:To implement a custom child checkout component for a B2B or B2C store created with an LWR template, the developer must implement the CheckoutStep interface from thecommerce/checkoutmodule. This interface defines the methods and properties that the child component must have to communicate with the parent checkout component and the checkout data provider. The CheckoutStep interface extends the UseCheckoutComponent interface, which provides the common functionality for all checkout components, such as loading and saving data, reporting validity, and handling errors.

The other options are not correct because:

A) CheckoutSavable is not a valid interface for a custom child checkout component. There is no such interface in thecommerce/checkoutmodule or the Lightning web component framework.

B) Checkoutoutinterface is not a valid interface for a custom child checkout component. There is no such interface in thecommerce/checkoutmodule or the Lightning web component framework.

C) CustomCheckout is not a valid interface for a custom child checkout component. There is no such interface in thecommerce/checkoutmodule or the Lightning web component framework.

Question No. 3

Which HTML element can be used as a root tag for a Lightning Web Component's HTML file?

A<body>

B

C<html>

D<template>

Show Answer

Correct Answer: D

In Lightning Web Components (LWC), the root tag for the component's HTML file must be <template>. This tag defines the markup structure for the component and is essential for the LWC framework to correctly render the component in the Salesforce Lightning Experience. The <template> tag is unique to LWC and is not interchangeable with standard HTML tags like <body>,

, or <html>. For more information, see the Salesforce LWC documentation: Salesforce LWC HTML Templates Documentation.

Question No. 4

Which practice is allowed when it comes to naming a Lightning web component's folder and associated files?

AIncluding whitespace

BUsing a single underscore

CUsing consecutive underscores

DUsing a single hyphen (dash)

Show Answer

Correct Answer: B

To name a Lightning web component's folder and associated files, the developer should follow these naming rules:

Must begin with a lowercase letter

Must contain only alphanumeric or underscore characters

Must be unique in the namespace

Can't include whitespace

Can't end with an underscore

Can't contain two consecutive underscores

Can't contain a hyphen (dash)

The only exception to the last rule is when separating the namespace from the component name in markup. For example, if the component is in the example namespace and has the name myComponent, the folder name should be myComponent, but the markup tag should be <example-my-component>. The hyphen character (-) is required by the HTML standard for custom element names. The other options are either invalid or not recommended. For example, including whitespace or using consecutive underscores will cause errors, and using a single underscore will look odd and may confuse developers consuming the component.Reference:B2B Commerce and D2C Commerce Developer Guide,Lightning Web Components Developer Guide

Question No. 5

What are three advantages of using ccLog over the Salesforce

standard System.debug class? (3 answers)

AThere is no need to use string concatenation to easily tag log statements with a subject.

BccLog can debug syntax errors found in the JavaScript.

CThere is no need to create a User Trace Flag.

DAppend #ccLog=<Logging Token Name> to the end of the storefront URL in order to get logs in the inspector console.

EThere is no need to manually set a cookie to debug with the Site Guest User.

Show Answer

Correct Answer: A, D, E

Three advantages of using ccLog over the Salesforce standard System.debug class are:

There is no need to use string concatenation to easily tag log statements with a subject. ccLog allows passing a subject parameter to the log method, which will prepend the subject to the log message. For example,ccLog.log('This is a message', 'Subject')will log[Subject] This is a message.

There is no need to create a User Trace Flag. ccLog can be enabled by setting the value of CO.logToken to true in CCAdmin, which will activate logging for all users who access the storefront.

There is no need to manually set a cookie to debug with the Site Guest User. ccLog can be enabled for the Site Guest User by appending #ccLog=<Logging Token Name> to the end of the storefront URL in order to get logs in the inspector console. For example,https://my-storefront.com/#ccLog=debugwill enable logging for the Site Guest User with the debug level. Salesforce Reference:B2B Commerce and D2C Commerce Developer Guide,Logging
