AD0-E717 Adobe Commerce Developer Professional Questions and Answers

To forward the request to a different action, the developer can use the following code in the controller:

return $resultForward->forward(‘action’);

where $resultForward is an instance of \Magento\Framework\Controller\Result\ForwardInterface and ‘action’ is the name of the action where the request should be forwarded.

There is no controllerjorward.xml configuration file or forwardToAction method in Adobe Commerce.

In Magento, to forward a request from one controller action to another, a developer can utilize the forward method available in the controller action class. This is achieved by returning a result from the action method that instructs Magento to forward the request to another action. The forward object is obtained by calling the$this->resultForwardFactory->create()method within the controller action. Then, the target action is specified by calling theforwardmethod on this object with the action name as the argument, such as$resultForward->forward('targetAction'). This approach is consistent with Magento's emphasis on using result objects to control the flow of request processing within its MVC architecture.

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​​.

To refresh the cache using the command line in Magento, the commandbin/magento cache:clean <type>is used. This command clears the cache for the specified type, such as configuration, layout, or block HTML. Cleaning the cache is an essential maintenance task that helps to update the store's frontend with the latest changes and ensure that customers see the most current content. This command is particularly useful during development or after making changes to the store's configuration or layout​​.

To override the current parent theme styles in a custom theme being developed for Adobe Commerce, the developer should use the_theme.lessfile. This file is specifically designed for customizing and overriding the default styles provided by the parent theme, making option B the correct choice. The_theme.lessfile is a central place for theme-specific customizations.

The "Visible on Catalog Pages on Storefront" attribute property determines whether or not the attribute value is displayed in the Additional Information tab on the product detail page. If this property is set to "no", the attribute value will not be displayed.

For a custom product attribute to be displayed in the Additional Information tab on the product detail page in Magento, it needs to be visible on the catalog pages on the storefront. This visibility is controlled by the attribute property "Visible on Catalog Pages on Storefront". When this property is set to "yes", Magento includes the attribute in the Additional Information tab, making it visible to customers browsing the product. This setting ensures that only relevant and intended attributes are shown on the storefront, allowing for better product information management and customer experience.

The Project Web Interface is the main dashboard for managing Adobe Commerce Cloud projects. This includes the ability to check the staging environment deployments history.

The developer can look up the history of deployments to the staging environment, including branch, git merge, and sync operations, in the Project Web Interface. This interface provides a detailed log of all actions taken on the project, including deployments, enabling developers to track changes and troubleshoot issues that may arise.

The Pub/ directory is the recommended webroot for the web server in Magento. This is because it contains all of the static content that is used by the Magento store, such as images, CSS, and JavaScript files.

The recommended webroot for the web server in a Magento project is thepub/directory. This directory is used to access Magento static files and is the safer option for webroot as it minimizes security risks by not exposing the entire application structure to the web​​.

Thepub/directory in Magento is designed to be the root directory for web servers. This design choice is intended to enhance security and efficiency by serving static files directly from this location, thereby reducing the need for PHP processing for these files. By setting the webroot topub/, it ensures that only the necessary files are publicly accessible, protecting the application's core code and structure from external access. This setup is a recommended best practice in Magento development for maintaining a secure and well-organized file system structure​​.

The "delete" method on the\Magento\Framework\Model\AbstractModelclass is used to remove a record from the database. This method will also cascade the delete to any related records.

In Magento, models that inherit from the\Magento\Framework\Model\AbstractModelclass interact with the database through the ORM (Object-Relational Mapping) layer. To remove a record from the database using such a model, thedeletemethod is used. This method encapsulates the logic for deleting the record associated with the model instance from its corresponding database table. By calling$model->delete(), where$modelis an instance of a model inheriting fromAbstractModel, Magento will perform the necessary operations to remove the record from the database, ensuring data integrity and consistency within the application.

The Cloud CLI for Commerce command that a developer would use to create an integration environment for a better development process is magento-cloud environment:branch . This command creates a new branch in the Git repository and a new environment in the Cloud project, using the specified parent environment as a base. The new environment inherits the code, data, and media files from the parent environment.

To create a new integration environment for development in an Adobe Commerce Cloud project, the developer would use the Cloud CLI for Commerce command:magento-cloudenvironment:branch <environment-name> <parent-environment-ID>. This command creates a new environment by branching from the specified parent environment, providing a separate environment for developing new features or testing without affecting the live site.

A bundle product is a product that is made up of a collection of other products. This type of product is ideal for selling products that are often purchased together, such as a printer and ink cartridges.

A bundle product in Adobe Commerce has the ability to build customizable products from a variety of options. Bundle products are ideal for creating custom kits or packages wherecustomers can choose from options for each component. For example, building a custom computer setup from selected components like monitors, keyboards, CPUs, etc. Grouped products are collections of standalone products that can be purchased individually, and virtual products are intangible items.

The database engine that is part of the infrastructure of Adobe Commerce Cloud projects is MariaDB. MariaDB is a fork of MySQL that offers improved performance, scalability, and security features.

The database engine that is part of the infrastructure of Adobe Commerce Cloud projects is MariaDB. Adobe Commerce Cloud is configured to use MariaDB, which is a binary drop-in replacement for MySQL and is chosen for its performance, reliability, and feature set.

A URL Rewrite in Magento changes the way a URL appears in the browser. This is particularly useful for improving the readability and SEO of a URL. For example, a URL rewrite can be used to transform a long and complex URL into a shorter and more user-friendly version. It's important to note that while a URL rewrite changes the URL's appearance in the browser, it doesn't change the actual location of the resource on the server. This distinction is crucial for understanding how Magento handles URL rewrites and redirects, facilitating a more intuitive navigation structure within the store without altering the underlying server resources​​.

To initialize a theme in Adobe Commerce, at least two files are required:registration.phpandtheme.xml. Theregistration.phpfile is used to register the theme within the system, andtheme.xmldefines the theme's name, parent (if any), and other metadata. Thetheme.lessfile is not required for theme initialization but may be used for custom styling. The correct option fortheme.xmlis represented as "theme.xml" (D), not "themexml" as mentioned in the options.

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.

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.

In Magento, each store has its own root category. The root category acts as the top-level category under which all other categories and products are organized for that particular store. This structure allows for different catalog structures across multiple stores within a Magento installation, enabling a tailored product offering and navigation experience for each store. The ability to assign a unique root category to each store is a fundamental aspect of Magento's multi-store functionality, providing the flexibility to cater to diverse market segments or branding requirements​​.

The Adobe Commerce table that stores all cron job data iscron_schedule. This table maintains records of all scheduled cron tasks, including their statuses, execution times, and any messages related to their execution. It plays a central role in Magento's scheduling system, allowing for the management and monitoring of background tasks that are essential for various system functions and integrations​​.

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​​.

The Cloud CLI for Commerce command that can be used to quickly view a specific log file for an Adobe Commerce Cloud project ismagento-cloud logs:show. This command allows developersto view log files directly from the command line, which is useful for debugging and monitoring the application's state without needing to access the file system directly.

"Update on save" is a valid index mode in Magento, where the index is set to update automatically whenever a change is saved. This mode ensures that the index remains up-to-date with the latest data changes, such as product or category updates, immediately reflecting these changes on the storefront. This real-time indexing is crucial for maintaining data accuracy and consistency across the Magento site, especially in dynamic environments with frequent updates​​​​.
