The developer then needs to commit and push the changes to the composer.json and composer.lock files and redeploy the environment. Verified Reference: [Magento 2.4 DevDocs]


質問 # 12
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. Set the sort order of the new observer to be less than that of the third-party vendor's observer.
  • C. Ensure the third-party module is listed in the <sequence> node of the developer's module.xmi file.

正解:B

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.


質問 # 13
An Adobe Commerce developer creates a new website using a data patch. Each website will have unique pricing by website. The developer does not have visibility into the production and staging environments so they do not know what the configuration currently is.
How would they ensure the configuration is deployed and consistent across all environments?
A)


  • A. Option B
  • B. Option C
  • C. Option A

正解:A

解説:
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.


質問 # 14
An Adobe Commerce developer is working on a custom gallery extension.
The module uses the Magento\catalog\Model\iinageUploader class for image uploading. The admin controller for custom image uploads is Vendor\CustomGallery\Controller\Adminhtml\Image\Upload.
The images need to be stored in different basePath and baseTmpPath than the default ones.
How can the default imageuploader class be extended and used without affecting the other modules that are already using it?

  • A.
  • B.
  • C.

正解:B

解説:
According to the ImageUploader component guide for Magento 2 developers, the ImageUploader UI component gives users the ability to upload images to the Magento Media Gallery. This component is a variation of the FileUploader component and uses the same configuration settings. The ImageUploader component uses the Magento\catalog\Model\iinageUploader class for image uploading, which has properties such as basePath and baseTmpPath that define where the images are stored. To extend the default imageuploader class and use it without affecting the other modules that are already using it, the developer needs to create a virtual type of this class in their module's di.xml file and specify different values for basePath and baseTmpPath. The developer also needs to inject their virtual type into their admin controller using the imageUploader argument. Therefore, option B is the correct answer, as it shows the correct di.xml and controller code to extend and use the imageuploader class. Verified Reference: https://devdocs.magento.com/guides/v2.3/ui_comp_guide/components/image-uploader/


質問 # 15
An Adobe Commerce developer is creating a new module to extend the functionality of the cart. The module is installed in app/code/CompanyName/ModuleName/.
How would an Adobe Commerce developer extend the existing CartltemPrices GraphQL schema to include a custom base_price field?

  • A. Create and Configure a <prefffrence> for Hagento\QuoteGraphQl\Model\Resolver\CartItemPrices that adds the base_price field in the resolve() function.
  • B. Add the following to the module's etc/graphqi/di.xmi file:
  • C. Add the following to the module's etc/schema.graphqis file:

正解:C

解説:
The developer can extend the existing CartltemPrices GraphQL schema to include a custom base_price field by adding the following code to the module's etc/schema.graphqls file:
extend type CartltemPrices { base_price: Money! @doc(description: "The base price of the cart item") } This code adds a new field called base_price to the CartltemPrices type and specifies that it is of type Money and it is not nullable. The @doc directive adds a description for the field that will be shown in the schema documentation. The developer also needs to create a custom resolver class for the base_price field and declare it in the di.xml file of the module.

質問 # 16
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. Get the data from the Project Web Interface dedicated section.
  • B. Execute ece-tools env:config:show services Command.
  • C. Run the magento-cloud relationships CLI Command.
  • D. Connect to server via SSH and read $_ENV['services'] variable.

正解:C、D

解説:
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.

質問 # 17
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. 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.
  • B. The webapi.xml file should be moved into the etc/webapi_rest/webapi.xml file.
  • C. The greturn annotation is missing in the MyVendor\Blog\Api\PostRepositoryInterf ace class.

正解:A

解説:
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.

質問 # 18
On an Adobe Commerce Cloud platform, what type of environment will be provisioned when launching the CLI for Commerce command magento-cloud environment:branch <environment-name> <parent-environment-id>?

  • A. An empty integration environment without any code or database.
  • B. An integration environment with fresh Adobe Commerce Cloud installation.
  • C. An integration environment with the code and database from the parent environment.

正解:C

解説:
The type of environment that will be provisioned when launching the CLI for Commerce command magento-cloud environment:branch <environment-name> <parent-environment-id> is an integration environment with the code and database from the parent environment. Integration environments are temporary environments that are used for testing and development purposes on the Adobe Commerce Cloud platform. They can be created from any branch of code and have their own dedicated database and services. When creating an integration environment using the CLI for Commerce command, the code and database from the parent environment are copied to the new integration environment, creating an exact replica of the parent environment. Verified Reference: [Magento 2.4 DevDocs]


質問 # 19
An Adobe Commerce developer has been asked to modify the PageBuilder slider content type to allow a new custom content type (other than slide) to be assigned as a child. The developer has already created the new content type called improved_slide in their module. They now need to create a new view/adminhtml/pagebuilder/content_type/slider. xml file in their module to allow the new content type to be a child of slider content types.
What is the correct xml to accomplish this?

  • A.
  • B.
  • C.

正解:B

解説:
The following XML will allow the new content type to be a child of slider content types:
<pagebuilder_content_type>
<type>slider</type>
<children>
<type>improved_slide</type>
</children>
</pagebuilder_content_type>
Use code with caution. https://bard.google.com/faq
This XML will tell Magento that the slider content type can have improved_slide content types as children.

An Adobe Commerce Cloud developer wants to be sure that, even after transferring database from Production to Staging, the payment configurations are still valid on the Staging environment.
What does the developer need to add to be sure that the configurations are always properly set?

  • A. Project level environment variables.
  • B. Lines in the dedicated core_conf ig_data_stg table.
  • C. Environment level environment variables.

正解:C

解説:
The developer needs to add environment level environment variables to be sure that the payment configurations are always properly set on the Staging environment. Environment variables are configuration settings that affect the behavior of the Adobe Commerce Cloud application and services. Environment variables can be set at the project level or the environment level. Project level variables apply to all environments, while environment level variables override the project level variables for a specific environment. The developer can use environment level variables to customize the payment configurations for the Staging environment without affecting other environments. Verified Reference: [Magento 2.4 DevDocs]


質問 # 24
An Adobe Commerce developer is writing an integration test. They checked some Integration Tests for Magento core modules for reference and noticed that they use data fixtures initialized by adding annotations to test classes. For example:

The developer wants to add their own fixture to test a MyVendor_MyModule they created. Which steps will make this possible?

  • A. 1. Create a PHP file with the fixture data inside their own module in [module dir]/Test/integration/_fiies/my_fixture.php.
    2. Add the following annotation to the test method:
  • B. 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:
  • C. 1. Create a PHP file With the fixture data in [magento root dir]/dev/tests/integration/testsuite/MyVendor/MyModule/_files/my_fixture.php.
    2. Add the following annotation to the test method:

正解:C

解説:
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.


質問 # 25
An Adobe Commerce developer is tasked with adding custom data to orders fetched from the API. While keeping best practices in mind, how would the developer achieve this?

  • A. Create an extension attribute on Nagento\sales\Api\E)ata\orderinterface and an after plugin on Magento\Sales\Model\Order: :getExtensionAttributes() to add the custom data.
  • B. Create a before plugin on Magento\sales\model\ResourceModel\order\collection: :load and alter the query to fetch the additional data. Data will then be automatically added to the items fetched from the API.
  • C. Create an extension attribute On Magento\Sales\Api\Data\OrderInterface and an after plugin On Magento\Sales\Api\OrderRepositoryInterface On geto and getListo to add the custom data.

正解:C

解説:
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.


質問 # 26
An Adobe Commerce developer is creating a new console command to perform a complex task with a lot of potential terminal output. If an error occurs, they want to provide a message that has higher visibility than some of the other content that may be appearing, so they want to ensure it is highlighted in red (as seen in the screenshot):

How can they customize the appearance of this message?

  • A. Wrap the output content in tags like <error>, <info>, or <comment>.
  • B. Call the setDecorationType(Stype) method On the Symfony\Console\Output\OutputInterface Object before Calling writeln().
  • C. Throw a new commandException with the desired message passed as an argument.

正解:B

解説:
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.

An Adobe Commerce developer has created a process that exports a given order to some external accounting system. Launching this process using the Magento CLI with the command php bin/magento my_module:order: process --order_id=<order_id> is required.
Example: php bin/magento my_module:order:process --order_id=1245.
What is the correct way to configure the command?

  • A.
  • B.
  • C.
  • D.

正解:D

解説:
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.

    2. Commit and push that code from the local environment.
    3. Move code to Production environment.
  • C. 1. Modify admin timeout into app/etc/config.php file.
    2. Commit and push that code from the local environment.
    3. Submit a support ticket to apply the changes.

正解:A

解説:
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]


質問 # 30
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 an after plugin On \Magento\Catalog\Api\Data\BasePriceInterface:: getPrice.
  • B. Create a plugin for\Magento\Catalog\Model\Indexer\Product\Price::executeRow.
  • C. Create an implementation for \Magento\Catalog\Hodel\Product\PriceModifierlnterf ace.

正解:B

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.

In addition to the configuration of the SCD.MATRIX variable to reduce amount of unnecessary theme files, what would be the next steps to reduce the downtime?

  • A. 1. Check SCD is configured under deploy phase.
    2. Decrease the SCD.THREADS to speed up the build process
  • B. 1. Check SCD is configured under the build phase.
    2. Check if Adobe Commerce Cloud automatically adjusts SCD.THREADS.
  • C. 1. Check SCD is configured under the build phase.
    2. Increase the SCD.THREADS to speed up the build process.

正解:C

解説:
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. Verified Reference: [Magento 2.4 DevDocs] 12
