Adobe AD0-E717 Adobe Commerce Developer Professional Exam Practice Test

Answer : A, D

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.

Answer : B, C

To initialize a theme in Adobe Commerce, at least two files are required: registration.php and theme.xml. The registration.php file is used to register the theme within the system, and theme.xml defines the theme's name, parent (if any), and other metadata. The theme.less file is not required for theme initialization but may be used for custom styling. The correct option for theme.xml is represented as 'theme.xml' (D), not 'themexml' as mentioned in the options.

Answer : C

When renaming a table in Magento, to prevent data loss, the developer must define the table and its columns mapping in the db_schema_whitelist.json file. This declarative schema approach ensures that the data migration tool knows about the changes and can migrate data from the old table to the newly named table without losing any data.

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.

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 '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.

Answer : C

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.

Verified Reference: [Adobe Commerce Developer Guide - Forward action result]

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 the forward method 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.
