NEW QUESTION # 20
A message queue currently has queue/consumer-wait-for-messages set to true, which allows the consumer process to run until a message is inserted into the queue. A piece of functionality is driven by data stored in the model
\Magento\variable\Model\variable and this value is only loaded once during the consumer run. If the variable is updated we want the consumer to restart so that the new value is loaded into memory without having to reload the variable on each message consumed.
The Adobe Commerce developer has created an after plugin on the \Magento\Variable\Model\variable:: save() function.
How would the developer use the plugin to trigger the consumer restart?

• A. Set the global Cache key trigger_consumer_restart t0 1.
• B. Call the function \Magento\Framework\MessageQueue\Consumers\TriggerRe5tartInterface:trigger().
• C. Call the function \Magento\Framework\MessageQueue\PoisonPill\Poi5onPillPutInterface::put().

Answer: B

Explanation:
The developer can use the plugin to trigger the consumer restart by calling the function \Magento\Framework\MessageQueue\Consumers\TriggerRe5tartInterface:trigger(). This function will write a flag to the cache storage that will be checked by the consumer process. If the flag is set, the consumer process will terminate itself and restart with the updated configuration. Verified Reference: [Magento 2.4 DevDocs] 1

NEW QUESTION # 21
An Adobe Commerce developer has created a new shipping carrier Everything has been implemented and the collectRates() and getAllowedMethodsQ functions can be seen below:


Given the above code, what would be the displayed cost of the shipping method and final amount charged to the customer?

• A. The shipping method would display $10 and customers would pay $10 for using the new shipping method.
• B. The shipping method would display $0 and customers would pay $0 for using the new shipping method.
• C. The shipping method would display SO but customers would pay a $10 handling fee for their order.

Answer: A

Explanation:
The shipping method would display $10 and customers would pay $10 for using the new shipping method. This is because the collectRates method sets the price and cost of the shipping method to 10 in the result object. The price is what is shown to the customer on the frontend and the cost is what is charged to the customer when they place the order. The handling fee is not used in this case because it is set to zero in the config.xml file. Verified Reference: [Magento 2.4 DevDocs] [Magento Stack Exchange]

NEW QUESTION # 22
An Adobe Commerce developer has added an iframe and included a JavaScript library from an external domain to the website. After that, they found the following error in the console:
Refused to frame [URL] because it violates the Content Security Policy directive.
In order to fix this error, what would be the correct policy ids to add to the csp_whitelist.xml file?

• A. default-src and object-src
• B. frame-src and script-src
• C. frame-ancestors and connect-src

Answer: C

Explanation:
The frame-ancestors directive specifies the domains that are allowed to embed the current page in an iframe. The connect-src directive specifies the domains that are allowed to be loaded by the current page through a <script> tag or XMLHttpRequest.
In this case, the developer has added an iframe that embeds a page from an external domain. The Content Security Policy (CSP) is preventing the iframe from being loaded because the domain of the external page is not listed in the frame-ancestors directive.
To fix this error, the developer needs to add the domain of the external page to the frame-ancestors directive. They can do this by adding the following line to the csp_whitelist.xml file:
<frame-ancestors>https://www.example.com</frame-ancestors>

NEW QUESTION # 23

NEW QUESTION # 25
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.

Answer: B

Explanation:
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.

NEW QUESTION # 27
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 webapi.xml file should be moved into the etc/webapi_rest/webapi.xml file.
• B. 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.
• C. The greturn annotation is missing in the MyVendor\Blog\Api\PostRepositoryInterf ace class.

Answer: B

Explanation:
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.

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.

NEW QUESTION # 30
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. Environment level environment variables.
• B. Project level environment variables.
• C. Lines in the dedicated core_conf ig_data_stg table.

Answer: A

Explanation:
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]

NEW QUESTION # 31
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. Run the magento-cloud relationships CLI Command.
• C. Connect to server via SSH and read $_ENV['services'] variable.
• D. Execute ece-tools env:config:show services Command.

Answer: B,C

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 # 33
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.

Answer: C

Explanation:
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.

NEW QUESTION # 35
An Adobe Commerce developer is asked to implement a 15% surcharge for all users from a 'Wholesale' customer group. Keeping best practices in mind, what is a correct to accomplish this?

• A. Declare a new total collector class to calculate the modified total if the current user is in the group, register it in the module's etc/sales .xml file, modify the checkout_cart_index.xml and checkout_index_index.xml layouts to include a new child in the totals block.
• B. Create a Cart Price Rule that applies only to the 'Wholesale' group. Specify no conditions for the rule, and in the Actions section, specify for the rule to apply a "Percent of product price discount", with the 'Discount Amount" field set to -15.
• C. Create an Observer to the cataiog_product_get_final_price event. Check if the current customer is in the 'Wholesale' group, and if so, retrieve the

Answer: C

Explanation:
product from the $observer->getEventC) data and Call $product->setData('final_price', $product->getData( 'final_price') * 1.15).
Explanation:
The possible reason why the payment method is missing in the admin is that in the module config.xml, the node can_use_internal was not set to true. This node determines whether the payment method can be used in the admin area or not. If it is set to false or omitted, the payment method will not be available for admin orders. To enable the payment method for admin use only, the node can_use_internal should be set to true and the node can_use_checkout should be set to false.

NEW QUESTION # 36
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.

Answer: C

Explanation:
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.

NEW QUESTION # 37
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. Only reservations no longer needed are removed by the cron job.
• C. The "Auto Cleanup" feature from Multi Source Inventory was disabled in configuration.

Answer: B

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.
