Adobe AD0-E716 Adobe Commerce Developer Expert Exam Practice Test

The developer can enable the magnification of CSS files on an Adobe Commerce Cloud Staging environment by locally running the command bin/magento config:set --lock-config dev/css/minify_files 1 from the command line. This will set the configuration value in the app/etc/config.php file and lock it from being changed in the Admin Panel. The developer then needs to commit the app/etc/config.php file and redeploy the environment.

The input_type attribute of a product EAV attribute specifies the type of input field that will be used to enter the value of the attribute in the admin panel. The textarea input type is used for WYSIWYG fields. If the input_type attribute is not set to textarea, then the attribute will not appear as WYSIWYG in the admin panel.

To fix this, the developer should set the input_type attribute to textarea.

The developer can turn on outgoing emails on an Adobe Commerce Cloud Staging environment by accessing the Project Web Interface and selecting the Staging environment. Then, the developer can select Configure environment and toggle Outgoing emails On. This will enable the SMTP service for the Staging environment and allow emails to be sent from the application.

 The steps necessary prior to redeploying in order to upgrade to Enhanced Integration Environments are to limit the number of integration branches to two and to submit a support ticket requesting the upgrade. Enhanced Integration Environments are an improved version of integration environments that offer better performance, stability, and security. They have a limit of four active branches at a time, but only two branches can be migrated from standard integration environments. The developer needs to delete or deactivate any extra branches before requesting the upgrade from Adobe support. Verified References: [Magento 2.4 DevDocs]

The developer should create an extension attribute on the Magento\Sales\Api\Data\OrderInterface interface and an after plugin on the Magento\Sales\Api\OrderRepositoryInterface::get() and Magento\Sales\Api\OrderRepositoryInterface::getList() methods.

The extension attribute will store the custom data. The after plugin will be used to add the custom data to the order object when it is fetched from the API.

Here is the code for the extension attribute and after plugin:

PHP

namespace MyVendor\MyModule\Api\Data;

interface OrderExtensionInterface extends \Magento\Sales\Api\Data\OrderInterface

{

/**

* Get custom data.

*

* @return string|null

*/

public function getCustomData();

/**

* Set custom data.

*

* @param string $customData

* @return $this

*/

public function setCustomData($customData);

}

namespace MyVendor\MyModule\Model;

class OrderRepository extends \Magento\Sales\Api\OrderRepositoryInterface

{

/**

* After get order.

*

* @param \Magento\Sales\Api\OrderRepositoryInterface $subject

* @param \Magento\Sales\Api\Data\OrderInterface $order

* @return \Magento\Sales\Api\Data\OrderInterface

*/

public function afterGetOrder($subject, $order)

{

if ($order instanceof OrderExtensionInterface) {

$order->setCustomData('This is custom data');

}

return $order;

}

/**

* After get list.

*

* @param \Magento\Sales\Api\OrderRepositoryInterface $subject

* @param \Magento\Sales\Api\Data\OrderInterface[] $orders

* @return \Magento\Sales\Api\Data\OrderInterface[]

*/

public function afterGetList($subject, $orders)

{

foreach ($orders as $order) {

if ($order instanceof OrderExtensionInterface) {

$order->setCustomData('This is custom data');

}

}

return $orders;

}

}

Once the extension attribute and after plugin are created, the custom data will be added to orders fetched from the API.

If the Sodium extension is installed, Argon 2ID13 will be chosen as the Magento default hashing algorithm. Otherwise, SHA256 will be used.

The Sodium extension is a PHP extension that provides cryptographic functions. Argon 2ID13 is a password hashing algorithm that is considered to be more secure than SHA256.

If the Sodium extension is installed, Magento will use Argon 2ID13 as the default hashing algorithm for customer passwords. If the Sodium extension is not installed, Magento will use SHA256 as the default hashing algorithm.

To ensure that the configuration is deployed and consistent across all environments, the developer can use the following steps:

Create a data patch that contains the configuration for the new website.

Deploy the data patch to all environments.

Use the magento deploy:status command to verify that the configuration has been deployed to all environments.

 According to the Magento Stack Exchange answer, UI components are used to render various elements on Magento admin pages, such as grids, forms, buttons, etc. UI components are defined in XML files that are located in the view/adminhtml/ui_component directory of each module. To add a custom logic to render a column in a grid, the developer should create a custom class extending MagentoUiComponentListingColumnsColumn and add the custom logic within the prepareDataSource method. This method receives an array of data sources and modifies them according to the column logic. The developer should also add an attribute class to the column node within the module’s customer_listing.xml file and specify their custom class name as its value. Verified References:

The developer can customize the appearance of the error message by calling the setDecorationType() method on the Symfony\Console\Output\OutputInterface object before calling writeln(). The setDecorationType() method takes a single argument, which is the type of decoration that the developer wants to use. In this case, the developer wants to use the STYPE_ERROR decoration, which will highlight the message in red.

Here is an example of how to customize the appearance of the error message:

$output = new Symfony\Console\Output\ConsoleOutput();

$output->setDecorationType(Symfony\Console\Output\OutputInterface::STYPE_ERROR);

$output->writeln('This is an error message.');

The output of this code will be an error message that is highlighted in red.

The reason why the new endpoint is not visible in swagger is that since the new endpoint is not anonymous, the merchant needs to enter a valid integration token in swagger in order to see the new method. The webapi.xml file specifies that the resource for the new endpoint is MyVendor_Blog::post, which means that only authorized users with this permission can access it. To generate an integration token, the merchant needs to create an integration in the admin panel and activate it. Then they can copy the token and paste it in swagger’s authorization field.

The extension attributes are missing because the collection="true" attribute is not set in the etc/extension_attributes.xmi file. This attribute tells Magento that the extension attributes should be returned when the quote is retrieved.

To fix this issue, the developer needs to add the collection="true" attribute to the my_attributes extension attribute.

Once the collection="true" attribute is set, the extension attributes will be returned when the quote is retrieved.

To display the "file upload" field and process the actual CSV import, the following two requirements must be met:

The developer must create a new system configuration setting that specifies the path to the CSV file.

The developer must create a new controller action that handles the file upload and import process.

The system.xml file is used to define system configuration settings. The following XML snippet shows how to define a new system configuration setting for the CSV file path:

XML

/path/to/csv/file

The Controller\Adminhtml\ShipmentFees controller class is used to handle the file upload and import process. The following code shows how to create a new controller action that handles the file upload and import process:

PHP

public function uploadAction()

{

$file = $this->getRequest()->getFile('shipment_fees_csv_file');

if ($file->isUploaded()) {

$importer = new ShipmentFeesImporter();

$importer->import($file);

}

return $this->redirect('adminhtml/system_config/edit/section/shipment_fees');

}

According to the How to use the Magento command-line interface (CLI) guide, to configure and run the Magento CLI, the developer needs to make the bin/magento file executable and then use it to run commands. To create a custom command, the developer needs to create a class that implements \Symfony\Component\Console\Command\Command and define its name, description, arguments, options, and logic. The developer also needs to register the command in the di.xml file of their module using the Magento\Framework\Console\CommandList argument. Therefore, option C is the correct answer, as it shows the correct class and di.xml code to configure the custom command. Verified References:

To ensure that the developer's observer runs after the observer defined by the third-party module, they need to set the sort order of the new observer to be less than that of the third-party vendor's observer.

The sort order is a number that is assigned to each observer. The lower the number, the earlier the observer will be executed.

For example, if the third-party vendor's observer has a sort order of 10, the developer's observer would need to have a sort order of 9 or lower.

The probable cause for the delay in reflecting the changes on the frontend after a full product import is the combination of the number of products, customer groups and websites. This leads to a huge amount of values being stored in the price index which is too large to be processed at a normal speed. The price index calculates the final price of each product for each customer group and website, taking into account various factors such as tax, discounts, catalog price rules, etc. When there are many products, customer groups and websites, the price index becomes very complex and time-consuming to update.

The next steps to reduce the downtime are to check that the SCD is configured under the build phase and to increase the SCD.THREADS to speed up the build process. The SCD stands for static content deployment, which is the process of generating and deploying static files such as CSS, JS, images, etc. By configuring the SCD under the build phase, the static files are generated before the code is deployed to the production environment, which reduces the downtime during deployment. The SCD.THREADS is a variable that determines how many threads are used for parallel processing during the SCD. By increasing the SCD.THREADS, the developer can improve the performance and efficiency of the SCD process.

To ensure the developer has access to push code in an Adobe Commerce Cloud project, the developer’s email must be added under Users in the Cloud Project Web UI and the developer needs to add SSH public key in the Cloud Account dashboard settings. The Cloud Project Web UI is a web interface that allows managing and configuring Adobe Commerce Cloud projects and environments. The developer’s email must be added under Users to grant them access to the project and assign them a role and permissions. The Cloud Account dashboard settings is a web interface that allows managing and configuring Adobe Commerce Cloud accounts and SSH keys. The developer needs to add SSH public key in the settings to enable secure connection to the project and environments via SSH. Verified References: [Magento 2.4 DevDocs]

To store a block in the system cache, the developer needs to set values for both the cache_lifetime and cache_key data properties of the block. The cache_lifetime property specifies how long the block should be cached, and the cache_key property specifies a unique identifier for the block.

The following code shows how to set the cache_lifetime and cache_key data properties of a block:

PHP

$block->setData('cache_lifetime', 600);

$block->setData('cache_key', 'my_custom_block');

Once the cache_lifetime and cache_key data properties have been set, the block will be stored in the system cache and will not be regenerated on each page load.

The plugin execution order is as follows:

PluginA::beforeDispatch()

PluginB::beforeDispatch()

PluginA::aroundDispatch()

The code in the around plugin

PluginB::afterDispatch()

PluginA::afterDispatch()

The aroundDispatch() method is executed in a separate scope, so the code in the around plugin will be executed after the beforeDispatch() methods of both plugins, but before the afterDispatch() methods of both plugins.

Here is a diagram that shows the plugin execution order:

PluginA

beforeDispatch()

aroundDispatch()

afterDispatch()

PluginB

beforeDispatch()

afterDispatch()
