AD0-E717 Adobe Commerce Developer Professional Questions and Answers

• A quote is a temporary object that represents the customer’s shopping cart before it is converted into an order1. A quote can be created by a guest or a registered customer, and it can be active or inactive depending on whether the customer has completed the checkout process or not2.
• The quote table stores the basic information about the quote, such as the customer ID, email, currency, subtotal, grand total, shipping method, payment method, and so on2. Each row in the quote table corresponds to one quote object, identified by a unique entity ID2.
• The quote item table stores the details of each product added to the quote, such as the product ID, SKU, name, price, quantity, discount amount, tax amount, and so on2. Each row in the quote item table corresponds to one quote item object, identified by a unique item ID2. A quote item object is associated with a quote object by the quote ID column in the quote item table2.
• When a customer adds a product to the cart, Magento creates or updates a quote object and a quote item object for that product. The quote object is initialized by the Magento\Quote\Model\Quote class, which implements the Magento\Quote\Api\Data\CartInterface interface3. The quote item object is initialized by the Magento\Quote\Model\Quote\Item class, which implements the Magento\Quote\Api\Data\CartItemInterface interface3.
• Magento uses various classes and interfaces to manipulate the quote and quote item objects, such as the Magento\Quote\Model\QuoteRepository class, which implements the Magento\Quote\Api\CartRepositoryInterface interface for saving and retrieving quotes from the database3, and the Magento\Quote\Model\QuoteManagement class, which implements the Magento\Quote\Api\CartManagementInterface interface for creating and submitting quotes to orders3.
• Magento also uses various events and observers to perform additional actions on the quote and quote item objects, such as applying discounts, calculating taxes, validating stock availability, and so on. Some of these events are: sales_quote_add_item, sales_quote_collect_totals_before, sales_quote_collect_totals_after, sales_quote_save_before, sales_quote_save_after, sales_model_service_quote_submit_before, sales_model_service_quote_submit_after.
• Magento provides various APIs for interacting with the quote and quote item objects, such as the Magento\Quote\Api\CartManagementInterface API for creating empty carts and placing orders from carts, the Magento\Quote\Api\CartItemRepositoryInterface API for adding, updating, and removing items from carts, and the Magento\Quote\Api\CouponManagementInterface API for managing coupons for carts.

The controller responsible for handling the /checkout URL is located in Controller/Checkout/Index.php in the Magento.Checkout module1. This controller extends from \Magento\Checkout\Controller\Index\Index, which implements the execute() method that renders the checkout page1.

In the Magento_Checkout module, the responsible controller for the /checkout URL can be found inController/Checkout/Index.php. This controller handles the index action for the checkout process, initiating the checkout page when a customer navigates to /checkout. The organization of controllers in Magento follows a convention where the URL path corresponds to the directory structure within the module, making it easier to locate and understand the functionality associated with specific routes​​.

In Magento, thegroupelement in the cron job configuration allows multiple cron jobs to share the same configuration settings, such as schedule, status, and execution time limits. This grouping facilitates the management of cron jobs, making it easier to configure and maintain them, especially when multiple tasks require similar or identical settings. By assigning cron jobs to a specific group, they inherit the group's configuration, streamlining the setup process and ensuring consistent execution parameters across related tasks​​.

After a thorough search of the provided documents, I couldn't find a direct reference to the specific CLI command for determining if static content signing is enabled in Magento. However, the typical command for checking configuration settings in Magento isbin/magento config:show <path>, where<path>is the configuration path for the setting you wish to view. Based on Magento's configuration path patterns and the options provided, the most logical choice would beB. bin/magento config:show dev/static/sign, although this cannot be confirmed without further context or documentation.

The two attribute input types that Adobe Commerce already has by default are Multiple Select and Text Field. Multiple Select allows the user to select multiple values from a list of options. Text Field allows the user to enter text in a single line.

The Geographic coordinate and Numeric Field input types do not exist in Adobe Commerce.

Magento, by default, provides various attribute input types to accommodate different data entry needs for product and customer attributes. The "Text Field" input type allows for single-line text input, suitable for short, textual data such as names, titles, or any other brief information. The "Multiple Select" input type enables the selection of multiple options from a predefined list, useful for attributes with multiple applicable values like colors, sizes, or features. These input types are part of Magento's flexible attribute system, allowing for customizable data entry fields that cater to diverse product and customer data requirements.

The Discard Subsequent Rules option is only applied if the pricing rules have different priorities. If two pricing rules have the same priority, the discount from both rules will be applied.

For the "Discard Subsequent Rules" option set to "Yes" to work effectively, each pricing rule must have a defined priority. When multiple discount rules can apply to the same product, Magento evaluates them in the order of their priority values. If a rule with "Discard Subsequent Rules" set to "Yes" is applied, any subsequent rules with lower priority (higher priority number) will not be applied to that product.

Soft dependencies for a module should be listed under the "suggest" section in thecomposer.jsonfile of the module. This section is used to list packages that enhance or work well with the module but are not strictly required for the module to function. By using the "suggest"section, developers can inform others about optional packages that could improve functionality or integration with the module, without making them mandatory dependencies​​.

The commandbin/magento indexer:reset <index_name>is used to invalidate a specific index in Magento. When an index is invalidated, it flags the index as 'Invalid' in the Index Management section of the Magento Admin, indicating that the data is out of sync and needs to be updated. This command does not perform the reindexing itself but prepares the specified index forreindexing by marking it as needing an update. This is an important step in ensuring that the Magento storefront reflects the most current data​​.

This file provides the shipping address of the current quote by using the getShippingAddress() method. For example, the following code snippet gets the shipping address from the quote object and logs it to the console:

define([

'Magento_Checkout/js/model/quote'

],function(quote) {

'use strict';

varshippingAddress = quote.getShippingAddress();

console.log(shippingAddress);

});

The file Magento_Quote/js/model/model does not exist in Magento 2, and the file Magento_Checkout/js/model/quote-shipping-address is not a valid way to access the shipping address of the current quote. You can read more about the quote object and its methods in the Magento 2 developer documentation.

In Adobe Commerce, the shipping address of the current quote is accessed through the JavaScript fileMagento_Checkout/js/model/quote. This file includes various quote-related data, including shipping and billing addresses, items in the cart, and totals. There is noMagento_Checkout/js/model/quote-shipping-addressfile, andMagento_Quote/js/model/modelis not a valid path, making option A the correct choice.

The type of product that would assist a seller in offering an electronic version of an album and selling each song individually is a Downloadable product. In Adobe Commerce, a Downloadable product type is specifically designed for selling digital products such as music files, which customers can download. This type of product allows sellers to upload individual songs and sell them separately or as part of a complete album.

To update the Staging environment with the latest code from the Production environment on an Adobe Commerce Cloud project, the developer would log in to the Project Web Interface, choose the Staging environment, and then click Sync. This action synchronizes the environments, bringing the latest changes from Production into Staging.

To display a custom attribute on the category edit page in the Magento admin panel, a developer should use the UI component approach. This involves creating acategory_form.xmlfile within theview/adminhtml/ui_componentdirectory of the module. This XML file defines the form fields (including any custom attributes) that should appear on the category edit page. The UI component system in Magento provides a flexible way to manage form elements and their interactions on the admin side, ensuring a consistent user interface and experience​​.

To enable filtering by attribute in a category's layered navigation, you should set the category's "Is Anchor" setting to "Yes". This setting is found in the category's display settings within the admin panel. When a category is set as "Anchor", Magento will automatically include filtering options in the layered navigation block for all attributes that are configured to be used in layered navigation.
