NEW QUESTION # 20
An international merchant is complaining that changes are taking too long to be reflected on the frontend after a full product import.
Thinking it may be database issues, the Adobe Commerce developer collects the following entity counts:
* Categories: 900
* Products: 300k
* Customers: 700k
* Customer groups : 106
* Orders: 1600k
* Invoices: 500k
* Creditmemos: 50k
* Websites : 15
* Stores : 45
What is a probable cause for this?
- A. The combination of the number of orders, customers, invoices and creditmemos is too big. This leads to a huge amount of values being stored in the customer grid index which is too large to be processed at a normal speed.
- B. The combination of the number of products, categories and stores is too big. This leads to a huge amount of values being stored in the flat catalog indexes which are too large to be processed at a normal speed.
- C. The combination of the number of products, customer groups and websites is too big. This leads to a huge amount of values being stored in the price index which is too large to be processed at a normal speed.
Answer: C
Explanation:
The probable cause for the delay in reflecting the changes on the frontend after a full product import is the combination of the number of products, customer groups and websites. This leads to a huge amount of values being stored in the price index which is too large to be processed at a normal speed. The price index calculates the final price of each product for each customer group and website, taking into account various factors such as tax, discounts, catalog price rules, etc. When there are many products, customer groups and websites, the price index becomes very complex and time-consuming to update.

NEW QUESTION # 21
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 integration environment with the code and database from the parent environment.
- B. An empty integration environment without any code or database.
- C. An integration environment with fresh Adobe Commerce Cloud installation.
Answer: A
Explanation:
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.

NEW QUESTION # 22
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 $_disat>iedAttrs class property array:
- A. Option C
- B. Option A
- C. Option B
Answer: B
Explanation:
The _transformAttrs class property array of the importer and exporter classes can be used to specify a serializer class for a particular attribute. The serializer class will be used to convert the attribute value from one format to another when the data is exported or imported.
In this case, the developer can specify a serializer class that will convert the JSON data in the media_gallery attribute to a string. This will prevent the software that the client is using to modify the exported data from changing the JSON data.
The following code shows how to specify a serializer class for the media_gallery attribute:
PHP
class MySerializer
{
public function serialize($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.
NEW QUESTION # 23
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 more PHP threads to be utilized during the process.
- B. This allows for a longer timeout per batch 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]

The module contains following models:
Download class has a parameter for tracking_level.
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: A
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\DownloadPdf>
<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.

2. Add the following annotation to the test method:
Answer: B
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 # 28
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. Column (student_name) does not have attribute length.
- B. Column (entity_id) does not have index. It is needed since attribute identity is set to false.
- C. null is not a valid value for column (roll_no).
- D. Column (roll_no) does not have index. It is needed since attribute identity is set to true.
Answer: A,D
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 # 29

What would be a possible reason?
- A. The input type is not set to textarea.
- B. The input type is not set to text.
- C. The is_html_allowed_on_front Option iS Set tO false.
Answer: A
Explanation:
The input_type attribute of a product EAV attribute specifies the type of input field that will be used to enter the value of the attribute in the admin panel. The textarea input type is used for WYSIWYG fields. If the input_type attribute is not set to textarea, then the attribute will not appear as WYSIWYG in the admin panel.
To fix this, the developer should set the input_type attribute to textarea.

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]
NEW QUESTION # 31
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.
NEW QUESTION # 32
An Adobe Commerce developer wants to generate a list of products using ProductRepositorylnterf ace and search for products using a supplier_id filter for data that is stored in a standalone table (i.e., not in an EAV attribute).
Keeping maintainability in mind, how can the developer add the supplier ID to the search?
- A. Write a before plugin On \Magento\Framework\Api\SearchCriteria\CollectionProcessorInterface: :process(). Iterate through the $searchCriteria provided for supplier_id, and if found, apply the needed join and filter to the passed scollection.
- B. Write a before plugin on \Hagento\catalogVtodel\ProductRepository: :geti_ist() and register the search criteria passed. Write an event observer to 0 listen for the event cataiog_product_coiiection_ioad_before. Iterate through the registered search criteria, and if found, apply the needed join and filter to the events scollection.
- C. Add a CUStOm filter to the Virtual type "agento\Catalog\Model\Api\SearchCriteria\CollectionProcessor\ProductFilterProce5sor for supplier_id field. In the custom filter, apply the needed join and filter to the passed $collection.
Answer: C
Explanation:
The developer can add a custom filter to the virtual type Magento\Catalog\Model\Api\SearchCriteria\CollectionProcessor\ProductFilterProce5sor for supplier_id field. In the custom filter, the developer can apply the needed join and filter to the passed $collection. This is the recommended way to extend the search criteria for products using dependency injection and plugins. Verified Reference: [Magento 2.4 DevDocs] [Magento Stack Exchange]
NEW QUESTION # 33
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 # 34
A logistics company with an Adobe Commerce extension sends a list of reviewed shipment fees to all its clients every month in a CSV file. The merchant then uploads this CSV file to a "file upload" field in admin configuration of Adobe Commerce.
What are the two requirements to display the "file upload" field and process the actual CSV import? (Choose two.) A)
- A.
- B.
- C.
- D.
Answer: B,D
Explanation:
To display the "file upload" field and process the actual CSV import, the following two requirements must be met:
The developer must create a new system configuration setting that specifies the path to the CSV file.
The developer must create a new controller action that handles the file upload and import process.
The system.xml file is used to define system configuration settings. The following XML snippet shows how to define a new system configuration setting for the CSV file path:
XML
<config>
<system>
<config>
<shipment_fees_csv_path>/path/to/csv/file</shipment_fees_csv_path>
</config>
</system>
</config>
The Controller\Adminhtml\ShipmentFees controller class is used to handle the file upload and import process. The following code shows how to create a new controller action that handles the file upload and import process:
PHP
public function uploadAction()
{
$file = $this->getRequest()->getFile('shipment_fees_csv_file');
if ($file->isUploaded()) {
$importer = new ShipmentFeesImporter();
$importer->import($file);
}
return $this->redirect('adminhtml/system_config/edit/section/shipment_fees');
}
NEW QUESTION # 35
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.
Answer: A
Explanation:
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.
