質問 # 24
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 no longer needed are removed by the cron job.
- B. The "Auto Cleanup" feature from Multi Source Inventory was disabled in configuration.
- C. Only reservations matching canceled orders are removed by the cron job.
正解：A
解説：
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.

質問 # 27
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.
正解：C
解説：
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.

An Adobe Commerce developer added a new API method to search and retrieve a list of Posts for a custom Blog functionality. This is the content of the module's etc/webapi.xml file:
The new code has been deployed to production and the merchant is using https: //merchant. domain. com/swagger to review the new endpoint, but it is not visible in swagger.
What would be a reason for this?
- A. The greturn annotation is missing in the MyVendor\Blog\Api\PostRepositoryInterf ace class.
- B. The webapi.xml file should be moved into the etc/webapi_rest/webapi.xml file.
- C. 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.
正解：C

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. Implement Patchversioninterface and return 1.5.4 on the getversion() method.
- B. This is not possible. A module cannot implement both data patch and install scripts.
- C. Inside apply() method, check for module version and run the code if version is less than 1.5.4.
正解：A
解説：
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:

An Adobe Commerce developer adds a new extension attribute to add an array of values to the invoices that are fetched through the APIs.
After a while, their technical manager reviews their work and notices something wrong with the extension_attributes. xml file that the developer created in their module:
What is the problem with this xml snippet?
- A. The type is wrong, string [] should be replaced with array.
- B. The extension attribute references the repository instead of the interface it implements (Magento\saies\Api\invoiceRepositorymterface).
- C. The extension attribute references the wrong interface, it should have referenced the Magento\saies\Api\data\invoiceinterface.
正解：B

The extension attribute is referencing the repository instead of the interface it implements. The correct XML snippet should be:
XML
<extension_attributes>
<attribute code="custom_values" type="string[]"
group="General"
translate="true">
<description>This attribute stores an array of custom values for the invoice.</description>
<source_model>Magento\Sales\Api\Data\InvoiceInterface</source_model>
</attribute>
</extension_attributes>
The source_model attribute specifies the interface that the extension attribute is associated with. In this case, the extension attribute is associated with the Magento\Sales\Api\Data\InvoiceInterface interface.

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.
正解：A
解説：
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.
質問 # 42
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 implement an observer on the coiiection_ioad_after event.
- B. 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" /> - C. The developer neglected to provide a plugin On Hagento\Quote\Api\CartRepositoryInterface: :get.
正解：B
解説：
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.
質問 # 43

質問 # 48
An Adobe Commerce developer has installed a module from a third-party vendor. This module fires a custom event named third_party_event_after and also defines an observer named third_party_event_after_observer that listens to that event. The developer wants to listen to this custom event in their own module but wants to execute their observer's logic after the third_party_event_after_observer observer has finished executing.
What would the developer do to ensure their observer runs after the observer defined by the third-party module?
- A. This is not possible as observers listening to the same event may be invoked in any order.
- B. Ensure the third-party module is listed in the <sequence> node of the developer's module.xmi file.
- C. Set the sort order of the new observer to be less than that of the third-party vendor's observer.
正解：C
解説：
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.
