Adobe AD0-E717 Adobe Commerce Developer Professional Exam Practice Test

Answer : A

Soft dependencies for a module should be listed under the 'suggest' section in the composer.json file 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.

Answer : C

To define a class as transient in Magento's di.xml, the correct approach is to set the shared attribute to 'false' for that class. This tells Magento's object manager not to use the singleton pattern for this class, meaning a new instance will be created each time the class is requested. This is particularly useful for classes that should not maintain state across different areas of the application or during a single request lifecycle.

Answer : C

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.

Verified Reference: [Adobe Commerce Developer Guide - EAV data model]

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.

Answer : C

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 in Controller/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.

Answer : B

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 the di.xml file. 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.

Answer : B

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.

Answer : C

The 'delete' method on the \Magento\Framework\Model\AbstractModel class 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\AbstractModel class interact with the database through the ORM (Object-Relational Mapping) layer. To remove a record from the database using such a model, the delete method 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 $model is an instance of a model inheriting from AbstractModel, Magento will perform the necessary operations to remove the record from the database, ensuring data integrity and consistency within the application.
