AD0-E717 Adobe Commerce Developer Professional Question and Answers

On an Adobe Commerce Cloud Enhanced Integration Environment, enabling Fastly CDN (Content Delivery Network) can significantly improve performance by caching content closer to the user's location, reducing load times. Additionally, removing all of the integration's inactive branches helps to optimize the environment by decluttering and focusing resources on active development. Restricting catalog size may not be feasible or desirable, and disabling cron jobs can disrupt necessary background operations unless specifically needed for performance testing or troubleshooting.

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 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​​.

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.

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​​.

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 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.

Thewebdirectory contains the static files that can be loaded directly. This directory includes files such as CSS, JavaScript, and images.

In Adobe Commerce themes, thewebdirectory is used to store static files such as CSS, JavaScript, images, and fonts. These files can be loaded directly by the browser. Thepreprocessedandassetsdirectories do not exist as standard directories in the theme structure for containing directly loadable static files.

To access RabbitMQ data on an Adobe Commerce Cloud Production environment, you can use local port forwarding. This allows you to forward a port on your local machine to a port on the Production environment. This way, you can connect to RabbitMQ from your local machine.

A developer would access RabbitMQ data on an Adobe Commerce Cloud Production environment using local port forwarding. This is done via an SSH tunnel that securely forwards a port from the local machine to the RabbitMQ service on the cloud environment. RabbitMyAdmin (an option that does not exist) and the Project Web Interface do not provide direct access to RabbitMQ data.

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.

A developer can prioritize the execution of a plugin by using thesortOrderproperty within the plugin's declaration in thedi.xmlfile. Specifying a lower value for thesortOrderproperty gives the plugin higher priority, meaning it will be executed before other plugins with a higher sortOrder value. This allows developers to control the order of plugin execution, which can be critical for ensuring the desired outcome when multiple plugins are affecting the same method​​.

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.

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.

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.

According to the Adobe Commerce User Guide, a tax class can be assigned to either a product or a customer group in Adobe Commerce. A product tax class determines how a product is taxed, while a customer tax class determines how a customer is taxed based on their location and group membership. Shipping is considered as a product tax class in Adobe Commerce, and it can be assigned to different shipping methods or rates. The other options are not valid for assigning a tax class.

In Adobe Commerce, tax classes can be assigned to products and shipping. Categories, however, do not have tax classes assigned to them directly. Tax classes applied to shipping allow merchants to specify how taxes should be calculated for shipping costs, making option B the correct answer. Orders and categories do not have direct associations with tax classes in the same way products and shipping do.

The read-only core file system on Adobe Commerce Cloud ensures that all changes to the production environment are tracked. This is because any changes to the code must go through version control, and the deployment pipeline, which includes stages like build, staging, and production. This approach helps maintain consistency across environments, ensures deployment best practices, and reduces human error by preventing direct changes on production servers.

The two methods that add sorting to collections inherited from the \Magento\Framework\Model\ResourceModel\Db\Collection\AbstractCollection class are setOrder and addOrder. These methods allow adding one or more order clauses to a collection query.

The setSorting and addSorting methods do not exist in Adobe Commerce.

Verified References: [Adobe Commerce Developer Guide - Collections]

In Magento 2, collections inherited from\Magento\Framework\Model\ResourceModel\Db\Collection\AbstractCollectionclass can be sorted using thesetOrderandaddOrdermethods. ThesetOrdermethod is used to set the order for a field in the collection, specifying the field by which to sort and the direction of the sorting (ASC or DESC). TheaddOrdermethod is similar but allows for adding multiple sorting orders to the collection, enabling more complex sorting scenarios. There are nosetSortingoraddSortingmethods in the standard Magento 2 collection classes.

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​​.

The Cloud Project Portal (Onboarding UI) of an Adobe Commerce Cloud project is a web interface that allows you to perform various actions related to your project, such as creating and managing environments, deploying code, configuring services, and adding users1. One of the actions that you can perform from the Cloud Project Portal is adding a Technical Admin, which is a user role that has full access to all environments and canperform any action on the project2. To add a Technical Admin from the Cloud Project Portal, you need to follow these steps2:

• Log in to the Cloud Project Portal with your Magento account credentials.
• Click on the Users tab on the left sidebar.
• Click on the Add User button on the top right corner.
• Enter the email address of the user you want to add as a Technical Admin.
• Select the Technical Admin role from the Role dropdown menu.
• Click on the Send Invitation button.

The user will receive an email invitation to join your project as a Technical Admin. They will need to accept the invitation and set up their account before they can access your project2.

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​​.
