What are two ways to access the PHP error logs on Adobe Commerce Cloud? (Choose Two.)
- A. Use the Adobe Admin Log application.
- B. Use the dedicated command from Cloud CLI for Commerce.
- C. Navigate to the dedicated entry in the Project Web Interface.
- D. Connect to the the servers via SSH and localize the log files.
正解：B、D
解説：
Two ways to access the PHP error logs on Adobe Commerce Cloud are to use the dedicated command from Cloud CLI for Commerce and to connect to the servers via SSH and localize the log files. The Cloud CLI for Commerce is a command-line tool that allows developers to interact with their Adobe Commerce Cloud projects and environments. The developer can use the command magento-cloud log php to view or download the PHP error logs from any environment. Alternatively, the developer can connect to the servers via SSH and navigate to the var/log directory where the PHP error logs are stored. Verified Reference: [Magento 2.4 DevDocs] 3
質問 # 35
A developer wants to deploy a new release to the Adobe Commerce Cloud Staging environment, but first they need the latest code from Production.
What would the developer do to update the Staging environment?
- A. 1. Checkout to Production environment
2. Use the magento-cloud synchronize <environment-ID> Commerce CLI Command - B. 1. Log in to the Project Web Interface.
2. Choose the Staging environment, and click Merge - C. 1. Log in to the Project Web Interface.
2. Choose the Staging environment, and click Sync
正解：C
解説：
The developer can update the Staging environment with the latest code from Production by logging in to the Project Web Interface, choosing the Staging environment, and clicking Sync. This will synchronize the code, data, and media files from Production to Staging, creating an exact copy of Production on Staging. The developer can then deploy the new release to Staging and test it before pushing it to Production. Verified Reference: [Magento 2.4 DevDocs]
質問 # 36
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. Execute ece-tools env:config:show services Command.
- D. Get the data from the Project Web Interface dedicated section.
正解：A、B
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 # 37
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 $_disat>iedAttrs class property array:
- A. Option C
- B. Option A
- C. Option B
正解：B
解説：
The _transformAttrs class property array of the importer and exporter classes can be used to specify a serializer class for a particular attribute. The serializer class will be used to convert the attribute value from one format to another when the data is exported or imported.
In this case, the developer can specify a serializer class that will convert the JSON data in the media_gallery attribute to a string. This will prevent the software that the client is using to modify the exported data from changing the JSON data.
The following code shows how to specify a serializer class for the media_gallery attribute:
PHP
class MySerializer
{
public function serialize($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.
質問 # 38

2. Add the custom logic within the afterPreparecoiumn method.
正解：C
質問 # 39
A Project Architect needs to add a new developer who needs to be able to push code in an Adobe Commerce Cloud project. No integration with a third-party repository provider is setup.
What two actions would be required to ensure the developer has access? (Choose Two.)
- A. The developer's email must be added under Users in the Cloud Project Web Ul
- B. The Adobe Commerce admin user must be created and the developer's SSH public key must be added on their local system
- C. The developer's SSH public key must be added into a file named ~/.ssh/authorized_keys
- D. The developer needs to add SSH public key in the Cloud Account dashboard settings
正解：A、D
解説：
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 Reference: [Magento 2.4 DevDocs]
質問 # 40
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 # 41
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 values for both cache_lifetime and cache_key data properties of the block.
- B. Set a value for cache_key data property of the block.
- C. Set a value for the cache_Lifetime data property of the block.
正解：A
解説：
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.

An Adobe Commerce developer is tasked to add a file field to a custom form in the administration panel, the field must accept only .PDF files with size less or equal than 2 MB. So far the developer has added the following code within the form component xml file, inside the fieldset node:
How would the developer implement the validations?
A)
Add the Validations Within the HyVendor\MyModule\Controller\Adminhtml\CustomEntity\UploadPdf Controller
B)
Add a virtual type forMyvendor\MyModuie\Modei\customPdfupioader specifying the aiiowedExtensions and the maxFiiesize for the constructor, within the module's di.xmi:
C)
Add the following code inside the<settings> node:
- A. Option C
- B. Option A
- C. Option B
正解：C
解説：
The developer can add a virtual type for Myvendor\MyModuie\Modei\customPdfupioader specifying the aiiowedExtensions and the maxFiiesize for the constructor, within the module's di.xmi. This way, the developer can reuse the existing file uploader class and customize it for the specific field without modifying the core code.

The di. xml file of a module attaches two plugins for the class Action.
The around plugin code is:
What would be the plugin execution order?
- A.
- B.
- C.
正解：C
解説：
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()

There is an integration developed using a cron service that runs twice a day, sending the Order ID to the integrated ERP system if there are orders that are able to create an invoice. The order is already loaded with the following code:
$order = $this->orderRepository->get($orderId);
In order to verify if the store has invoices to be created, what implementation would the Adobe Commerce developer use?
- A.
- B.
- C.
正解：B
解説：
The developer can use the canInvoice method of the order object to check if the order can be invoiced or not. This method returns true if the order has a state of new, processing, or payment review and has not been fully invoiced yet. The developer can use this method in a conditional statement to send the order ID to the ERP system only if the order can be invoiced.

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. Lines in the dedicated core_conf ig_data_stg table.
- B. Environment level environment variables.
- C. Project level environment variables.
正解：B
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 # 46
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 implementation for \Magento\Catalog\Hodel\Product\PriceModifierlnterf ace.
- B. Create a plugin for\Magento\Catalog\Model\Indexer\Product\Price::executeRow.
- C. Create an after plugin On \Magento\Catalog\Api\Data\BasePriceInterface:: getPrice.
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.
質問 # 47
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 implement an observer on the coiiection_ioad_after event.
- C. The developer neglected to provide a plugin On Hagento\Quote\Api\CartRepositoryInterface: :get.
正解：A
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.

An Adobe Commerce Developer is tasked with creating a custom form which submits its data to a frontend controller They have decided to create an action and have implemented the \Magento\Framework\App\Action\HttpPostActioninterface class, but are not seeing the data being persisted in the database, and an error message is being shown on the frontend after submission.
After debugging and ensuring that the data persistence logic is correct, what may be cause and solution to this?
- A. Magento does not allow POST requests to a frontend controller, therefore, the submission functionality will need to be rewritten as an API endpoint.
- B. The developer forgot to implement a validatePostDataQ method in their action. They should implement this method: all non-validated POST data gets stripped out of the request and an error is thrown.
- C. Form key validation runs on all non-AJAX POST requests, the developer needs to add the for_key to their requests.
正解：C
解説：
According to the Magento Stack Exchange answer, form key validation is a security feature that prevents CSRF attacks by checking if the form key in the request matches the one generated by Magento. If the developer does not include the form_key in their custom form, the validation will fail and an error will be shown. Therefore, the developer needs to add the form_key to their requests by using <?= $block->getBlockHtml ('formkey') ?> in their template file.

<Vendor\FreeDownload\Model\DownloadImage>
<rewrite name="tracking_level" value="4"/>
</Vendor\FreeDownload\Model\DownloadImage>
</models>
</global>
</config>
The setting element is used to set a configuration value for a specific model. The rewrite element is used to override the default configuration value for a specific model. In this case, the tracking_level parameter is set to 4 for all models that extend Download.
