NEW QUESTION # 38
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. Add the following to the module's etc/schema.graphqis file:
  
• B. Add the following to the module's etc/graphqi/di.xmi file:
  
• C. Create and Configure a <prefffrence> for Hagento\QuoteGraphQl\Model\Resolver\CartItemPrices that adds the base_price field in the resolve() function.

Answer: A

Explanation:
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.

NEW QUESTION # 39
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 in [magento root dir]/dev/tests/integration/testsuite/MyVendor/MyModule/_files/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/_fiies/my_fixture.php.
  2. Add the following annotation to the test method:
  
• C. 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:
  

Answer: A

Explanation:
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.

NEW QUESTION # 40
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. null is not a valid value for column (roll_no).
• B. Column (roll_no) does not have index. It is needed since attribute identity is set to true.
• C. Column (student_name) does not have attribute length.
• D. Column (entity_id) does not have index. It is needed since attribute identity is set to false.

Answer: B,C

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 # 41
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. Run the magento-cloud relationships CLI Command.
• B. Get the data from the Project Web Interface dedicated section.
• C. Execute ece-tools env:config:show services Command.
• D. Connect to server via SSH and read $_ENV['services'] variable.

Answer: A,D

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 # 42
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.

Answer: A

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.

NEW QUESTION # 43
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.

Answer: B

Explanation:
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.

NEW QUESTION # 44
When researching some issues with the indexer, an Adobe Commerce developer is seeing errors in the logs similar to Memory size allocated for the temporary table is more than 20% of innodb_buffer_pool_size. It is suggested that the client update innodb_buf f er_pool_size or decrease the batch size value.
Why does decreasing the batch size value improve performance?

• A. This allows for a longer timeout per batch process.
• B. This allows for more PHP threads to be utilized during the process.
• C. This decreases memory usage for the temporary table.

Answer: C

Explanation:
Decreasing the batch size value improves performance by reducing the memory usage for the temporary table. The batch size value determines how many rows of data are processed at a time by the indexer. A large batch size value can cause the allocated memory size for the temporary table to exceed 20% of innodb_buffer_pool_size, which can result in errors and slow down the indexing process. By lowering the batch size value, the indexer can process the data more efficiently and avoid memory issues. Verified Reference: [Magento 2.4 DevDocs] [Magento Stack Exchange]

NEW QUESTION # 45
For security reasons, merchant requested to a developer to change default admin url to a unique url for every branch/environment of their Adobe Commerce Cloud project.
Which CLI command would the developer use update the admin url?

• A. bin/magento adminuri:set <admin_uri>
• B. ece-tools variable:update ADMIN_URL
• C. magento-cloud variable:set ADMIN_URL

Answer: C

Explanation:
The CLI command that the developer would use to update the admin url is magento-cloud variable:set ADMIN_URL. This command sets an environment variable called ADMIN_URL with a custom value for the admin url on a specific environment. Environment variables are configuration settings that affect the behavior of the Adobe Commerce Cloud application and services. By setting an environment variable for ADMIN_URL, the developer can change the default admin url to a unique url for every branch/environment of their Adobe Commerce Cloud project.

NEW QUESTION # 46
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. Inside apply() method, check for module version and run the code if version is less than 1.5.4.
• B. This is not possible. A module cannot implement both data patch and install scripts.
• C. Implement Patchversioninterface and return 1.5.4 on the getversion() method.

Answer: C

Explanation:
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.

NEW QUESTION # 47
An Adobe Commerce developer has added a new configuration field to the admin are a. The path for this option is general/store_information/out_of_hours_phone.
Keeping simplicity in mind, how would the developer ensure this option contains a valid US telephone number?

• A. Create a backend model to check the validity of the phone number entered.
• B. Add <validate>phoneUS</validate> to the field in system.xml.
• C. Add <validate type="phoneUS"/> to the field in system.xml.

Answer: B

Explanation:
According to the Magento Stack Exchange answer, system.xml is a file that defines the configuration fields for the admin area. Each field can have a validate attribute that specifies a validation rule for the field value. Magento provides some built-in validation rules, such as phoneUS, which validates a US telephone number. Therefore, to ensure that the option contains a valid US telephone number, the developer needs to add <validate>phoneUS</validate> to the field in system.xml.

How will the developer configure the tracking_level parameter, in di.xml.to have a value of 4 for Download class and all classes that extend Download?

• A.
• B.
• C.

Answer: C

Explanation:
To configure the tracking_level parameter in di.xml to have a value of 4 for the Download class and all classes that extend Download, the developer would use the following code:
<config>
<global>
<models>
<Vendor\FreeDownload\Model\Download>
<setting name="tracking_level" value="4"/>
</Vendor\FreeDownload\Model\Download>
<Vendor\FreeDownload\Model\DownloadPdf>
<rewrite name="tracking_level" value="4"/>

<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.

NEW QUESTION # 50
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.

Answer: B

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 # 51
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. Ensure the third-party module is listed in the <sequence> node of the developer's module.xmi file.
• B. This is not possible as observers listening to the same event may be invoked in any order.
• 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.
