AD0-E717 Adobe Commerce Developer Professional Questions and Answers

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.

The correct way to inject a CMS block into a layout in Adobe Commerce is by using the<block>element with the classMagento\Cms\Block\Blockand specifying the block identifier through an<argument>element with the name "block_id". This is shown in option A. The<block>tag defines the block class and name, and the<arguments>tag contains child<argument>tags for each argument, where the "block_id" argument specifies the identifier of the CMS block to be injected.

On an Adobe Commerce Cloud project, a custom patch should be placed in them2-hotfixes/directory to have it automatically applied during the build phase. The patches in this directory are applied in alphabetical order and can be used to apply quick fixes to the code that will be included in the build artifact.

A persistent cart is a cookie that is stored on the customer's computer. This cookie allows the customer to continue shopping even if they close their browser. If the customer is logged in, the persistent cookie will remain active even if the session cookie expires.

Associated with a persistent cart in Adobe Commerce is the characteristic that while the customer is logged in, if the session cookie expires, the persistent cookie will remain active. This ensures that the customer's shopping cart is preserved even if they have been inactive and the session has expired. The persistent cookie allows the cart to be restored when the customer returns to the store.

Theview/{area}/web/css/source/main.lessfile is the default less file that is included by default. This file contains the main styles for the module.

In a custom module in Adobe Commerce, the default location for including custom LESS styles is typicallyview/{area}/web/css/source/_module.less. However, the most commonly used file for adding global styles isview/{area}/web/css/source/_extend.less. Theview/{area}/web/css/style.lessfile is not standard, and themain.lessfile is used as an entry point for compilation but typically does not contain custom styles directly.

When creating configuration fields for the admin panel and setting their default values, a developer should use theetc/config.xmlfile within their module. This file is used to declare default values for the module's configuration options. When Magento is installed or the module is enabled, these values are automatically loaded into the database, under thecore_config_datatable, setting the initial configuration for the module. This approach ensures that the module has sensible defaults and operates correctly upon installation​​

By default, third-party modules are located in vendor/ or app/code/ directories. The vendor/ directory contains modules that are installed using Composer, while the app/code/ directory contains modules that are manually copied or cloned from a repository.

Third-party modules in Magento 2 are typically located in two directories by default: thevendor/directory and theapp/code/directory. Thevendor/directory is used for modules that are installed via Composer, Magento's dependency manager, which includes both Magento's core modules and third-party modules. Theapp/code/directory is used for custom modules developed specifically for the project or for third-party modules that are manually installed without Composer. These conventions provide a structured approach to managing Magento modules, whether they are part of Magento's core functionality, contributed by the community, or developed for specific projects​​.

The URL key of a product is the text that is used to generate the product's URL. This text can be set by the merchant in the product admin form.

The URL key of a product in Adobe Commerce can be changed in the product admin form under the "Search Engine Optimization" fieldset. Here, the URL key can be set or edited manually, allowing for customization beyond the automatically generated value. This field is typically used to ensure that the product URL is search-engine friendly and relevant to the product.

To translate strings added in JavaScript files in Adobe Commerce, developers need to use themage/translateRequireJS module along with the$.mage.__('<string>')function to mark strings for translation. This approach ensures that any text strings embedded within JavaScript code can be localized according to the store's current locale, providing a consistent and accessible user experience across different languages and regions. Themage/translatemodule and the$.mage.__()function work together to retrieve the corresponding translated strings from Magento's translation dictionaries, dynamically replacing the original text in the JavaScript code with the appropriate translations​​.

On the Adobe Commerce Cloud Project Web Interface, clicking on the "Delete" button of an integration environment will completely delete the environment, including the associated git branch and database. This action is irreversible and is used to remove an environment that is no longer needed. The environment, once deleted, frees up resources for the project and cannot be restored.

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 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​​.

Multiple EAV attributes belonging to the same entity are grouped in the database based on their data types, such as datetime, decimal, int, text, or varchar. For example, all attributes with datetime values are stored in one table, while all attributes with text values are stored in another table.

The sizes or numeric/text values of attributes do not determine how they are grouped in the database.

Magento's EAV (Entity-Attribute-Value) model organizes attributes based on their data types to optimize storage and retrieval. Attributes are grouped into different tables based on whether they store values of types such as integer, varchar (text), decimal, datetime, etc. This organization allows Magento to efficiently manage the diverse data types associated with products, customers, and other entities, ensuring data integrity and optimizing database performance by using appropriate indexing and storage mechanisms for each data type.

In Magento, the default store ID for the admin panel is 0. This is used as a fallback mechanism where, if the current store view's ID is not 0, Magento automatically adds 0 as a fallback. This ensures that the admin panel has a unique identifier, differentiating it from the frontend store views, which typically start with IDs higher than 0. This setup is crucial for Magento's multi-store architecture, allowing for distinct configurations and behaviors between the admin and frontend contexts​​.

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.
