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.

To expose delivery time estimates to NTO's customers in the storefront, a developer should display the Expected Delivery Date on the order page with a Lightning web component. The Expected Delivery Date is a custom field on the Order object that stores the date when the order is expected to be delivered to the customer. The developer can use the @wire decorator to get the current order object and use its properties, such as order number, status, total amount, and expected delivery date, to display them on the order page. The developer can also use Apex methods or third-party APIs to calculate and update the expected delivery date based on various factors, such as inventory availability, shipping method, shipping address, and carrier service level. Displaying the expected delivery date on the order page allows the customer to see their delivery time estimate at any time and reduce their need to call customer service. Adding the Expected Delivery Date field to the order confirmation email is not a good solution, as it does not allow the customer to see their delivery time estimate if they lose or delete their email. Adding a Desired Delivery Date input field during the checkout flow is not a good solution either, as it does not guarantee that the customer's desired delivery date will be met or reflect any changes in delivery time due to unforeseen circumstances. Configuring an email alert to the customer when the Expected Delivery Date changes is not a good solution either, as it can create confusion or frustration for the customer if they receive multiple or conflicting emails about their delivery date.

The template that will correctly display the details message only when areDetailsVisible becomes true given the following code in a Lightning Web Component is option C. Option C uses the if:true directive to conditionally render a template block based on the value of areDetailsVisible. If areDetailsVisible is true, the template block inside the <template if:true={areDetailsVisible}> tag will be rendered. Otherwise, it will be skipped. Option A is incorrect because it uses the if:false directive, which does the opposite of if:true. It renders the template block only when areDetailsVisible is false. Option B is incorrect because it uses an invalid syntax for the if directive. The if directive requires a colon (:) after the if keyword, not an equal sign (=). Option D is incorrect because it uses an invalid syntax for the template tag. The template tag requires a closing tag (</template>), not a self-closing tag (<template/>). Salesforce

Two advantages of using Lightning Data Service are that it combines and de-duplicates server calls and that it loads record data progressively. Lightning Data Service is a service that provides access to Salesforce data and metadata in Lightning web components. It optimizes performance and minimizes server round trips by caching data on the client side and sharing data across components. It also combines and de-duplicates server calls by batching requests for the same record or object and returning a single response. It also loads record data progressively by returning available cached data first and then fetching updated data from the server asynchronously. Communicating with other components and converting between different data formats are not advantages of using Lightning Data Service, as they are not related to its functionality or features.

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 user indicating that the org is in debug mode, as debug mode is a transparent setting that does not affect the user interface. Salesforce

The XML fragment that the developer should include in the component's configuration XML file to ensure the custom component is available to add to the page is option B. Option B uses the <targets> tag to specify where the component can be used in an app. The <targets> tag contains a list of <target> tags, each of which defines a valid target for the component. The value of the <target> tag for the Product Detail page in the store is lightningCommunity__RecordPage, which means that the component can be used on any record page in a Lightning community. Option A is incorrect because it uses an invalid value for the <target> tag. There is no such target as lightningCommunity__ProductDetailPage. Option C is incorrect because it uses an invalid syntax for the <targets> tag. The <targets> tag should not have any attributes, such as isAvailable. Option D is incorrect because it uses an invalid syntax for the <target> tag. The <target> tag should not be self-closing, but rather have a closing tag (</target>). Salesforce

Two statements that are accurate about the Cart Item with a Type of Charge are that it is linked directly to a Cart Id and that it is linked directly to a Catalog Id. A Cart Item with a Type of Charge is a special type of Cart Item that represents an additional charge or fee that is applied to a Cart, such as shipping, handling, or tax. A Cart Item with a Type of Charge is linked directly to a Cart Id, which means that it belongs to a specific Cart and can be retrieved or updated along with other Cart Items. A Cart Item with a Type of Charge is also linked directly to a Catalog Id, which means that it references a specific Catalog that contains the products and prices for the store. A Cart Item with a Type of Charge is not created with the Cart Delivery Group Method after the shipping integration or after the freight integration, as these are not related to the creation of Cart Items. The Cart Delivery Group Method is a method that determines how products are grouped into delivery groups based on their shipping methods and addresses. The shipping integration and the freight integration are integrations that calculate and apply shipping costs and freight charges to a Cart or an Order. Salesforce

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.

Three actions that a developer must take, in a B2B Commerce store, to accept credit card payments using a client's chosen payment provider are: create a named credential for authentication with the payment provider, create an Apex class that implements the sfdc_checkout.PaymentGatewayAdapter interface, and create a PaymentProviderGateway record for the custom payment provider class. Creating a named credential for authentication with the payment provider allows the developer to securely store and manage authentication information, such as username, password, token, or certificate, for connecting to the payment provider's API or service. Creating an Apex class that implements the sfdc_checkout.PaymentGatewayAdapter interface allows the developer to define custom logic for processing credit card payments using the payment provider's API or service. The interface provides methods for validating credit card information, authorizing payments, capturing payments, voiding payments, and refunding payments. Creating a PaymentProviderGateway record for the custom payment provider class allows the developer to register the custom payment provider class as a payment gateway in the store and associate it with a payment method. Creating a RegisteredExternalService record for the custom payment provider class is not a required action, as this is only used for registering external services that are not related to payment processing, such as tax or shipping services. Creating an Apex class that implements the commercepayments.PaymentGatewayAdapter interface is not a required action either, as this is only used for D2C Commerce stores, not B2B Commerce stores.
