NEW QUESTION # 13
When checking the cron logs, an Adobe Commerce developer sees that the following job occurs daily:
main.INFO: Cron Dob inventory_cleanup_reservations is successfully finished. However, the inventory_reservation table in the database is not emptied. Why are there records remaining in the inventory_reservation table?
- A. The "Auto Cleanup" feature from Multi Source Inventory was disabled in configuration.
- B. Only reservations matching canceled orders are removed by the cron job.
- C. Only reservations no longer needed are removed by the cron job.
Answer: C
Explanation:
The reason why there are records remaining in the inventory_reservation table is that only reservations no longer needed are removed by the cron job. The inventory_reservation table tracks the quantity of each product in each order and creates a reservation for each product when an order is placed, shipped, cancelled or refunded. The initial reservation has a negative quantity value and the subsequent reservations have positive values. When the order is complete, the sum of all reservations for the product is zero. The cron job removes only those reservations that have a zero sum from the table, leaving behind any reservations that are still needed for incomplete orders.

NEW QUESTION # 14
An Adobe Commerce developer has added a new configuration field to the admin area. The path for this option is general/store_information/out_of_hours_phone.
Keeping simplicity in mind, how would the developer ensure this option contains a valid US telephone number?
- A. Create a backend model to check the validity of the phone number entered.
- B. Add <validate type="phoneUS"/> to the field in system.xml.
- C. Add <validate>phoneUS</validate> to the field in system.xml.
Answer: C
Explanation:
According to the Magento Stack Exchange answer, system.xml is a file that defines the configuration fields for the admin area. Each field can have a validate attribute that specifies a validation rule for the field value.
Magento provides some built-in validation rules, such as phoneUS, which validates a US telephone number.
Therefore, to ensure that the option contains a valid US telephone number, the developer needs to add
<validate>phoneUS</validate> to the field in system.xml. Verified References:

NEW QUESTION # 15
How would a developer enable the magnification of CSS files on an Adobe Commerce Cloud Staging environment?
- A. Locally from the command line
bin/magento config:set --lock-config dev/css/minify_files 1
Commit the app/etc/config.php file and redeploy. - B. SSH to the Adobe Commerce Staging environment. From the command line
- C. Update the stores > setting > configuration > Advanced > Developer > css configuration in the Admin Panel.
Answer: A
Explanation:
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. Verified References: [Magento 2.4 DevDocs] 2
NEW QUESTION # 16
An Adobe Commerce Developer has written an importer and exporter for a custom entity. The client is using this to modify the exported data and then re-importing the file to batch update the entities.
There is a text attribute, which contains information related to imagery in JSON form, media_gallery. This is not a field that the client wants to change, but the software they are using to edit the exported data seems to be modifying it and not allowing it to import correctly.
How would the developer prevent this?
A) Specify a serializer class for the attribute using the $_transformAttrs class property array for both the exporter and importer so it gets converted:
B) Strip the attribute from the imported file by adding it to the s_strippedAttrs class property array:
C) Prevent it from being exported by adding it to the $_disat>iedAttrs class property array:
- A. Option A
- B. Option C
- C. Option B
Answer: A
Explanation:
The _transformAttrs class property array of the importer and exporter classes can be used to specify a serializer class for a particular attribute. The serializer class will be used to convert the attribute value from one format to another when the data is exported or imported.
In this case, the developer can specify a serializer class that will convert the JSON data in the media_gallery attribute to a string. This will prevent the software that the client is using to modify the exported data from changing the JSON data.
The following code shows how to specify a serializer class for the media_gallery attribute:
PHP
class MySerializer
{
public function serialize($value)
{
return json_encode($value);
}
public function deserialize($value)
{
return json_decode($value);
}
}
$importer->setSerializer('media_gallery', MySerializer::class);
$exporter->setSerializer('media_gallery', MySerializer::class);
Once the serializer class has been specified, the JSON data in the media_gallery attribute will be converted to a string when the data is exported or imported. This will prevent the software that the client is using to modify the exported data from changing the JSON data.
NEW QUESTION # 17
An Adobe Commerce developer successfully added a new column to the customers grid. This column needs the data to be formatted before showing its content in the grid.

2. Add the custom logic within the prepareDataSource method.
3. Add an attribute class to the column node within the module's customer_listing.xml. - B. 1. Override the Magento\Customer\Ui\Component\DataProvider Class using a preference.
2. Override the getData() method and add the custom logic per row. - C. 1. Create an after pluginforMagento\Ui\Component\Listing\Columns\Column::prepareColumn().
2. Add the custom logic within the afterPreparecoiumn method.
Answer: C
NEW QUESTION # 18
The developer is required to convert a modules database scripts from old install/upgrade setup files to a data patches format and does not want to apply database changes that were already done by install/upgrade scripts.
The current module version is 1.5.4.
What would be the recommended solution to skip changes that were already applied via old format (install/upgrade scripts)?
- A. This is not possible. A module cannot implement both data patch and install scripts.
- B. Implement Patchversioninterface and return 1.5.4 on the getversion() method.
- C. Inside apply() method, check for module version and run the code if version is less than 1.5.4.
Answer: B
Explanation:
According to the Develop data and schema patches guide for Magento 2 developers, data patches are classes that contain data modification instructions. They are defined in a
<Vendor>/<Module_Name>/Setup/Patch/Data/<Patch_Name>.php file and implement MagentoFrameworkSetupPatchDataPatchInterface. Data patches can also implement Patchversioninterface to specify the module version that the patch is associated with. The getVersion() method returns the module version as a string. To skip changes that were already applied via old format (install/upgrade scripts), the developer should implement Patchversioninterface and return 1.5.4 on the getVersion() method. This way, the data patch will only be applied if the module version is greater than or equal to 1.5.4. Verified References:

NEW QUESTION # 19
An Adobe Commerce developer is tasked with creating a custom block that will be displayed on every page in the footer of the site.
After completing and optimizing the development, the developer notices that the block takes too much time to be generated on each page and decides to store it in the system cache after enabling it for all cache groups.
What would be the minimum requirement to achieve this?
- A. Set a value for cache_key data property of the block.
- B. Set values for both cache_lifetime and cache_key data properties of the block.
- C. Set a value for the cache_Lifetime data property of the block.
Answer: B
Explanation:
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.
NEW QUESTION # 20
A developer is working on an Adobe Commerce Cloud project and wants to get connection data for the environment's deployed services. The developer has all of the necessary permissions to do this.
Which two options would the developer take to get the connection credentials? (Choose Two.)
- A. Connect to server via SSH and read $_ENV['services'] variable.
- B. Run the magento-cloud relationships CLI Command.
- C. Get the data from the Project Web Interface dedicated section.
- D. Execute ece-tools env:config:show services Command.
Answer: A,B
Explanation:
Two options to get the connection credentials for the environment's deployed services are to run the magento-cloud relationships CLI command and to connect to the server via SSH and read $_ENV['services'] variable. The magento-cloud relationships CLI command displays information about the relationships between an environment and its services, such as database, cache, search, etc. The developer can use this command to get the connection data for each service in JSON format. Alternatively, the developer can connect to the server via SSH and read the $_ENV['services'] variable, which contains the same information as the CLI command output.

NEW QUESTION # 21
An Adobe Commerce developer has been tasked with applying a pricing adjustment to products on the website. The adjustments come from a database table. In this case, catalog price rules do not work. They created a plugin for getPrice on the price model, but the layered navigation is still displaying the old price.
How can this be resolved?
- A. Create a plugin for\Magento\Catalog\Model\Indexer\Product\Price::executeRow.
- B. Create an after plugin On \Magento\Catalog\Api\Data\BasePriceInterface:: getPrice.
- C. Create an implementation for \Magento\Catalog\Hodel\Product\PriceModifierlnterf ace.
Answer: A
Explanation:
The developer can resolve this issue by creating a plugin for the Magento\Catalog\Model\Indexer\Product\Price::executeRow() method. This method is responsible for updating the product price index.
The plugin can be used to add the pricing adjustment from the database to the product price index. Once the product price index is updated, the layered navigation will display the correct price.
Here is an example of a plugin for the executeRow() method:
PHP
class MyPlugin
{
public function executeRow(
\Magento\Catalog\Model\Indexer\Product\Price $subject,
\Magento\Catalog\Model\Product $product,
array $data
) {
$adjustment = $this->getAdjustment($product);
$product->setPrice($product->getPrice() + $adjustment);
}
private function getAdjustment(Product $product)
{
$adjustment = $product->getData('adjustment');
if (!is_numeric($adjustment)) {
return 0;
}
return $adjustment;
}
}
This plugin will add the adjustment data from the product to the product price index. Once the product price index is updated, the layered navigation will display the correct price.

NEW QUESTION # 26
There is the task to create a custom product attribute that controls the display of a message below the product title on the cart page, in order to identify products that might be delivered late.
The new EAV attribute is_delayed has been created as a boolean and is working correctly in the admin panel and product page.
What would be the next implementation to allow the is_delayed EAV attribute to be used in the .phtml cart page such as $block->getProduct()->getIsDelayed()?
A)
Create a new file etc/catalog_attributes.xmi:
B)
Create a new file etc/extension attributes.xmi:
C)
Create a new file etc/eav attributes.xmi:
- A. Option A
- B. Option C
- C. Option B
Answer: A
Explanation:
To allow the is_delayed EAV attribute to be used in the .phtml cart page, the developer needs to create a new file called etc/catalog_attributes.xmi. This file will contain the definition of the is_delayed attribute.
The following code shows how to create the etc/catalog_attributes.xmi file:
XML
<?xml version="1.0"?>
<catalog_attributes>
<attribute code="is_delayed" type="int">
<label>Is Delayed</label>
<note>This attribute indicates whether the product is delayed.</note>
<sort_order>10</sort_order>
<required>false</required>
</attribute>
</catalog_attributes>
Once the etc/catalog_attributes.xmi file has been created, the is_delayed attribute will be available in the
.phtml cart page. The attribute can be accessed using the getIsDelayed() method of the Product class.
PHP
$product = $block->getProduct();
$isDelayed = $product->getIsDelayed();
The isDelayed variable will contain the value of the is_delayed attribute. If the value of the attribute is 1, then the product is delayed. If the value of the attribute is 0, then the product is not delayed.

When checking the cron logs, an Adobe Commerce developer sees that the following job occurs daily: main.INFO: Cron Dob inventory_cleanup_reservations is successfully finished. However, the inventory_reservation table in the database is not emptied. Why are there records remaining in the inventory_reservation table?
- A. The "Auto Cleanup" feature from Multi Source Inventory was disabled in configuration.
- B. Only reservations matching canceled orders are removed by the cron job.
- C. Only reservations no longer needed are removed by the cron job.
Answer: C
Explanation:
The reason why there are records remaining in the inventory_reservation table is that only reservations no longer needed are removed by the cron job. The inventory_reservation table tracks the quantity of each product in each order and creates a reservation for each product when an order is placed, shipped, cancelled or refunded. The initial reservation has a negative quantity value and the subsequent reservations have positive values. When the order is complete, the sum of all reservations for the product is zero. The cron job removes only those reservations that have a zero sum from the table, leaving behind any reservations that are still needed for incomplete orders.

NEW QUESTION # 28
A logistics company with an Adobe Commerce extension sends a list of reviewed shipment fees to all its clients every month in a CSV file. The merchant then uploads this CSV file to a "file upload" field in admin configuration of Adobe Commerce.
What are the two requirements to display the "file upload" field and process the actual CSV import? (Choose two.) A)
- A.
- B.
- C.
- D.
Answer: B,D
Explanation:
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
<config>
<system>
<config>
<shipment_fees_csv_path>/path/to/csv/file</shipment_fees_csv_path>
</config>
</system>
</config>
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');

2. Add the following annotation to the test method:
- E. Option B
- F. 1. Create a PHP file with the fixture data inside their own module in [module dir]/Test/integration/_f iies/my_f ixture.php.
2. Add the following annotation to the test method:
Answer: C
Explanation:
To add a custom fixture to test a MyVendor_MyModule, the developer needs to do the following:
* Create a PHP file with the fixture data in [magento root
* dir]/dev/tests/integration/testsuite/MyVendor/MyModule/_files/my_fixture.php.
* Add the following annotation to the test method:
@magentoDataFixture(
'testsuite/MyVendor/MyModule/_files/my_fixture.php'
)
This will tell Magento to load the fixture data from the my_fixture.php file before the test method is executed.

An Adobe Commerce developer has created a module that adds a product attribute to all product types via a Data Patch-According to best practices, how would the developer ensure this product attribute is removed in the event that the module is uninstalled at a later date?
- A. Add an Uninstall.php file extending \l1agento\Framework\Setup\UninstallInterface tO the module's Setup directory and implement the uninstall method.
- B. Add instructions to the module's README.md file instructing merchants and developers that they must manually remove this attribute if they want to uninstall the module.
- C. Make the Data Patch implement \Magento\Framework\setup\Patch\PatchRevertabieinterface and implement the revert method to remove the product attribute.
Answer: C
Explanation:
According to the Develop data and schema patches guide for Magento 2 developers, data patches can also implement PatchRevertabieinterface to provide rollback functionality for their changes. The revert() method contains the instructions to undo the data modifications made by the patch. To ensure that the product attribute is removed when the module is uninstalled, the developer should make the data patch implement PatchRevertabieinterface and implement the revert method to remove the product attribute using EavSetupFactory or AttributeRepositoryInterface.
