Adobe AD0-E717 Adobe Commerce Developer with Cloud Add-on Exam Practice Test

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.

In Magento, plugins (Interceptors) can only intercept public methods. This is because the plugin system relies on Magento's object manager to dynamically create proxy classes that can intercept method calls. Since private and final methods are not accessible from outside the class they are defined in, and static methods are not called on an object instance, these method types cannot be intercepted. This mechanism allows for the extension and customization of Magento's core behavior in a transparent and non-intrusive manner​​.

To extend an existing jQuery widget in Adobe Commerce, the$.widgetfunction is used. This function is part of jQuery UI's widget factory and is a powerful tool for creating stateful plugins with a consistent API. It allows developers to create a new widget that inherits from an existing widget, enhancing or modifying its functionality, making option C the correct answer.

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​​.

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.

To include a grid or form in an admin page layout using the UI Component, the correct approach is to use the<uiComponent name="example_listing"/>within a<referenceContainer name='content'>block of the layout XML file. This method directly references the UIcomponent's configuration file (e.g.,example_listing.xml) which defines the structure and functionality of the UI component, such as grids or forms. This configuration file is located under theview/adminhtml/ui_componentdirectory of the corresponding module​​.

If a developer fails to mention the start date in the "From" field when creating a price rule, the price rule will be saved. However, the price rule will not go into effect until the start date is added.

If a developer fails to mention the start date in the "From" field when creating a price rule in Adobe Commerce, the system will default to the current date, and the price rule will go into effect as soon as it is saved. The absence of a start date means there is no delay in the activation of the rule, and it becomes effective immediately upon saving.

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.

To add an image icon in front of the telephone field in the shipping address form on the checkout page, the correct way is to modify the UI component by setting a custom template file for the field. The snippet in option B is the correct one because it uses the<block>element and sets theelementTmplto the custom template path within theargumentsnode under theconfignode. This modification will instruct Magento to use the specified custom template file for rendering the telephone field, allowing for the addition of an image icon in front of it.

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 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.

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​​.

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.

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.

To override a private method in a third-party module class, the most effective approach is to use a preference. This involves creating a custom class with the corrected logic and then defining this class as a preference for the original one in thedi.xmlfile. Plugins cannot be used to override private methods, final methods, final classes, or classes created without dependency injection. Therefore, the preference mechanism, which allows for the substitution of the entire class, becomes the viable method to override a private method and modify its behavior​​.

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.

If a developer wants to allow the removal of columns from the database when deleting them fromdb.schema.xml, they need to define the removable columns in thedb_schema_whitelist.jsonfile. This file will tell Magento which columns can be removed from the database.

To allow columns to be removed from the database when they are deleted fromdb_schema.xml, they must be listed in thedb_schema_whitelist.jsonfile. This file acts as a reference for which database schema elements are safe to modify or delete, providing a safeguard against unintentional data loss during schema updates.

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.

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.

The.magento.env.yamlfile is used on an Adobe Commerce Cloud project to customize the environment configuration, including the PHP version and enabling/disabling PHP extensions. This YAML configuration file provides the ability to manage service configurations and is essential for customizing the Cloud environment.

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.

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.

Tier prices are used to provide discounts for products based on quantity. For example, you could set a tier price that allows customers to buy two products for X amount each.

The tier price is used when a developer wants to offer a discount based on the quantity purchased. For example, buying two or more units of a product at a reduced price per unit. Tier pricing allows setting different prices for different quantities, encouraging customers to buy more. Special price is a flat discounted price regardless of quantity, and group price is used to set special prices for specific customer groups, not for quantity-based discounts.
