NEW QUESTION # 28
An Adobe Commerce developer was asked to provide additional information on a quote. When getting several quotes, the extension attributes are returned, however, when getting a single quote it fails to be returned.
What is one reason the extension attributes are missing?
- A. The developer neglected to add coiiection="trueM to their attribute in etc/extension_attributes.xmi file. O ottribute code="my_attributesM type="MyVendor\MyModule\Api\Data\^AttributeInterface[]M collection="true" />
- B. The developer neglected to provide a plugin On Hagento\Quote\Api\CartRepositoryInterface: :get.
- C. The developer neglected to implement an observer on the coiiection_ioad_after event.
Answer: A
Explanation:
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.
<attribute code="my_attributes" type="MyVendor\MyModule\Api\Data\AttributeInterface[]" collection="true" /> Once the collection="true" attribute is set, the extension attributes will be returned when the quote is retrieved.
NEW QUESTION # 29
An Adobe Commerce developer is asked to create a new payment method for their project. This project has administrators who use the backend to manage customer information and occasionally place orders. When testing the new payment method on the frontend everything worked as expected, however, the payment method is missing in the admin.
What is a possible reason for this?
- A. In the module config.xmi, the node can_use_internal was not set to true.
- B. In the module config.xmi, the boolean value for can_capture was set to false.
- C. In the module di.xml, there were no default 3DS verification types configured as a VirtualType.
Answer: A
NEW QUESTION # 30
An Adobe Commerce developer is trying to create a custom table using declarative schema, but is unable to do so.
What are two errors in the snippet above? (Choose two.)
- A. Column (entity_id) does not have index. It is needed since attribute identity is set to false.
- B. Column (student_name) does not have attribute length.
- C. null is not a valid value for column (roll_no).
- D. Column (roll_no) does not have index. It is needed since attribute identity is set to true.
Answer: B,D
Explanation:
The correct answers are A and C.
The errors in the snippet are:
Column roll_no does not have an index. It is needed since attribute_identity is set to true.
Column student_name does not have an attribute length.
The attribute_identity attribute specifies whether the primary key of the table should be auto-incremented. If attribute_identity is set to true, then the roll_no column must have an index. The student_name column does not have an attribute length, which is required for string columns.
The following code shows how to fix the errors:
XML
<table name="vendor_module_table">
<entity_id>
<type>int</type>
<identity>true</identity>
<unsigned>true</unsigned>
<nullable>false</nullable>
</entity_id>
<roll_no>
<type>int</type>
<identity>false</identity>
<unsigned>true</unsigned>
<nullable>false</nullable>
<primary_key>true</primary_key>
<index>true</index>
</roll_no>
<student_name>
<type>string</type>
<length>255</length>
<nullable>false</nullable>
</student_name>
</table>
Once the errors have been fixed, the table can be created successfully.
NEW QUESTION # 31
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,C
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');
}
NEW QUESTION # 32
An Adobe Commerce Developer wishes to add an action to a pre-existing route, but does not wish to interfere with the functionality of the actions from the original route.
What must the developer do to ensure that their action works without any side effects in the original module?
- A. Add the action into to the controllers/front_name/ in My.Module, Magento will automatically detect and use it.
- B. In the route declaration, use the before or after parameters to load their module in before or after the original module.
- C. Inject the new action into the standard router constructor's $actiomist parameter.
Answer: B
Explanation:
To add an action to a pre-existing route without interfering with the functionality of the original route, the developer must use the before or after parameters in the route declaration. This will load the developer's module in before or after the original module, respectively.
For example, the following code would add an action to the my_module/index route before the action from the original module:
<route id="my_module/index">
<before>my_module_before</before>
<action class="MyModule\Controller\Index">
<arguments>
<argument name="context" type="Magento\Framework\App\Action\Context"/>
</arguments>
</action>
</route>
The my_module_before action would be executed before the MyModule\Controller\Index action, which would allow the developer to perform any necessary setup before the original action is executed.
NEW QUESTION # 33
An Adobe Commerce developer is working on a Magento 2 instance which contains a B2C and a B2B website, each of which contains 3 different store views for English, Welsh, and French language users. The developer is tasked with adding a link between the B2C and B2B websites using a generic link template which is used throughout the sites, but wants these links to display in English regardless of the store view.
The developer creates a custom block for use with this template, before rendering sets the translate locale and begins environment emulation using the following code:
They find that the template text is still being translated into each stores language. Why does this occur?
- A. startEnvironmffntEmulation() SetS and locks the locale by Using the setLocale() Optional Second $lock parameter, i.e. setLocale($newLocaleCode, true), to override and lock the locale of the emulated store. If this is set and locked initially then the environment emulation will not be able to override this.
- B. setLocate() does not change translation locale after it has been initially set, the $this->_translate->emulate($newLocaiecode) method exists to temporarily modify this by pushing the new locale to the top of the current emuiatedLocales stack.
- C. startEnvironmentEmuiation() resets the translation locale to the one of the emulated stores, which overrides the locale the developer has set when the order of setLocate and startEnvironmentEmulation is used as displayed above.
Answer: C
Explanation:
The startEnvironmentEmulation() method resets the translation locale to the one of the emulated stores, which overrides the locale the developer has set when the order of setLocale() and startEnvironmentEmulation() is used as displayed above.
The correct way to achieve the desired result is to use the emulate() method to temporarily modify the translation locale. The following code shows how to do this:
PHP
$this->_translate->emulate('en_US');
// Render the template
$this->_translate->revert();
This code will set the translation locale to English before rendering the template, and then revert the locale back to the default value after the template has been rendered.
The startEnvironmentEmulation() method is used to emulate a different store view or website. This can be useful for testing purposes, or for developing features that need to work in different environments.
The emulate() method is used to temporarily modify the translation locale. This can be useful for rendering templates in a specific language, or for testing features that need to work in different languages.
NEW QUESTION # 34
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. Only reservations matching canceled orders are removed by the cron job.
- B. The "Auto Cleanup" feature from Multi Source Inventory was disabled in configuration.
- 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.

- B. In the Environment-specific variables.
- C. In the Integration variables.
Answer: A
Explanation:
The variable env: composer_auth is located in the Project variables section in the Project Web Interface. This variable is used to store the authentication credentials for Composer repositories that require access keys or tokens. The developer can set this variable at the project level to apply it to all environments, or override it at the environment level if needed. Verified Reference: [Magento 2.4 DevDocs] 2
NEW QUESTION # 36
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 $_disat>iedAttrs class property array:
- A. Option C
- B. Option B
- C. Option A
Answer: C
Explanation:
The _transformAttrs class property array of the importer and exporter classes can be used to specify a serializer class for a particular attribute. The serializer class will be used to convert the attribute value from one format to another when the data is exported or imported.
In this case, the developer can specify a serializer class that will convert the JSON data in the media_gallery attribute to a string. This will prevent the software that the client is using to modify the exported data from changing the JSON data.
The following code shows how to specify a serializer class for the media_gallery attribute:
PHP
class MySerializer
{
public function serialize($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.

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.

3. Move code to Production environment. - C. 1. In the Fastly Configuration section > Advanced Configuration.
2. Set the Admin path timeout value in seconds.
3. Save config and Upload VCL to Fastly.
Answer: C
Explanation:
The developer can deal with this issue by modifying the admin path timeout value in seconds in the Fastly Configuration section > Advanced Configuration in the Admin Panel. Fastly is a cloud-based caching service that improves site performance and security for Adobe Commerce Cloud projects. Fastly has a default timeout value of 180 seconds for admin requests, which means that any request that takes longer than 180 seconds will be terminated and result in a timeout error. The developer can increase this value to allow longer processing time for admin requests without causing errors. The developer also needs to save the configuration and upload VCL to Fastly to apply the changes. Verified Reference: [Magento 2.4 DevDocs]
