NEW QUESTION # 14
An Architect is investigating a deployment issue with a server that is configured to work under the symlink directory /var/www/current, which lead to the latest released version of the application.
The deployment process performs the following steps:
After the last deployment, the merchant reported that the Adobe Commerce Import/Export functionality to export Customer Main File data is not working. The Architect discovered that the export file is not shown in the list of generated files.
Which change to the deployment process should be performed to solve this issue?
- A. Doable Crontab before deployment and re-launch after deployment.
- B. Restart the consumer process during deployment to use the directory with a new application version for export files.
- C. Execute Command config:set export/customr/files_directory /var/releases/{release_nunber} toSet the new export path.
Answer: C
Explanation:
Explanation
The issue is that the export file is not shown in the list of generated files. This is because the export path is not set correctly. The solution is to execute the command config:set export/customr/files_directory
/var/releases/{release_nunber} to set the new export path. This will ensure that the export file is saved in the correct directory and can be accessed from the Admin Panel. References:

NEW QUESTION # 15
An existing Adobe Commerce website is moving to a headless implementation.
The existing website features an "All Brands'' page, as well as individual pages for each brand. All brand-related pages are cached in Varnish using tags in the same manner as products and categories.
Two new GraphQL queries have been created to make this information available to the frontend for the new headless implementation:
During testing, the queries sometimes return out-of-date information. How should this problem be solved while maintaining performance?
- A. Each GraphQL query's resolver class should inject \Magento\GraphQlcache\Model\cacheableQuery and call setcachevalidity(true) on it as part of the resolver's resolve function.
- B. Specify a $cache(cacheidentity: Path\\To\\identityclass) directive for each GraphQL query, corresponding to a class that adds cache tags for relevant brands and associated products
- C. Specify a @cacgecacheable(cacheable: false) directive for each GraphQL query, making sure that the data returned is not cached, and is up to date
Answer: B
Explanation:
Explanation
This solution ensures that the data returned by the GraphQL queries is up to date, while also maintaining performance. By specifying a $cache(cacheidentity: Path\To\identityclass) directive for each GraphQL query, the relevant brands and associated products will be added as cache tags.
NEW QUESTION # 16
An Adobe Commerce Architect is creating a new GraphQL API mutation to alter the process of adding configurable products to the cart. The mutation accepts configurable product ID. If the given product has only one variant, then the mutation should add this variant to the cart and return not nullable Carttype. If the configurable product has more variants, then the mutation should return not nullable Conf igurableProduct type.
The mutation declaration looks as follows:
How should the Adobe Commerce Architect declare output of this mutation?
- A.
- B.
- C.
Answer: C
Explanation:
Explanation
According to the Adobe Commerce documentation, the output of a GraphQL mutation is declared by specifying the type of the data returned by the mutation. The type can be either a scalar type (such as String, Int, Boolean, etc.), an object type (such as Cart, Product, Customer, etc.), or a union type (such as SearchResult, which can be either Product or Category). A union type is used when the mutation can return more than one possible type of data, depending on the input or the logic of the mutation. In this case, the mutation can return either a Cart type or a ConfigurableProduct type, depending onthe number of variants of the configurable product. Therefore, the output of the mutation should be declared as a union type that includes both Cart and ConfigurableProduct types. Option B is the only option that correctly declares a union type using the pipe symbol (|) to separate the possible types. Option A and Option C are incorrect because they use brackets ([ ]) and curly braces ({ }), which are used for declaring list types and input object types, respectively.

NEW QUESTION # 17
An Adobe Commerce store owner sets up a custom customer attribute "my.attribute".
An Architect needs to display additional content on the home page, which should display only to Customers with "my.attribute" of a certain value and be the same content for all of them. The website is running Full Page Cache.
With simplicity in mind, which two steps should the Architect take to implement these requirements? (Choose two.)
- A. Add a dynamic block with the content to the Home Page
- B. Add a new context value of "my_attribute" to Magento\Framework\App\Http\Context
- C. Add a custom block and a pHTML template with the content to the cmsjndexjndex.xml layout
- D. Create a Customer Segment and use 'my.attribute' in the conditions
- E. Use customer-data JS library to retrieve "my.attribute" value
Answer: A,B
Explanation:
Explanation
To display additional content on the home page based on a custom customer attribute, the Architect needs to do the following steps:
Add a new context value of "my_attribute" to Magento\Framework\App\Http\Context. This will allow the Full Page Cache to generate different versions of the page for customers with different values of
"my.attribute". The context value can be set using a plugin on the Magento\Customer\Model\Context class.
Add a dynamic block with the content to the Home Page. A dynamic block is a type of content block that can be configured to display only to specific customer segments or conditions. The Architect can use the 'my.attribute' in the conditions of the dynamic block and assign it to the Home Page in the Content > Blocks section of the Admin Panel. References:

NEW QUESTION # 18
A single Adobe Commerce Cloud instance is set up with two websites (each with a single store view) with different domains.
* The default website is website_one, with store view store_one, and domain storeone. com.
* The second website is website_two, with store view store_two, and domain storetwo. com.
The magento-vars. php file is set up as follows to determine which website each request runs against:
When testing a new GraphQL integration, all requests returned data relating to the default website, regardless of the domain. What is causing this issue?
- A. $_server["mage_run_cooe") needs to be setto store and *$_SERVER["MAGE_RUN_TYPE"] needs to be set to the store code instead.
- B. The magento-vars.php file is not processed for any GraphQL requests, so the default website is always processed.
- C. GraphQL requests are always run against the default store view unless a store header or store cookie is provided.
Answer: C
Explanation:
Explanation
The magento-vars.php file is used to set the website or store view based on the HTTP host, but it does not affect GraphQL requests. GraphQL requests are handled by a separate controller that does not use the magento-vars.php file. Instead, GraphQL requests use the default store view of the default website, unless a store header or store cookie is provided in the request. The store header or cookie should contain the store code of the desired store view. For example, to query data from website_two, the request should include a header like store: store_two or a cookie like store=store_two12.

NEW QUESTION # 19
An Adobe Commerce Architect designs and implements functionality that introduces a new Complex Product Type to the existing Adobe Commerce website. Besides visual demonstration of the new product type, the changes include adjustments to the price index.
The website utilizes a multi-dimensional indexer feature to store the price index. The Architect decides to cover it with integration tests. After creating and running one test, the Architect discovers that database storage is not being fully cleaned.
The test method has the following annotation declaration:
Which adjustment should the Architect make to fix this issue?
- A. Create Customer_ProductType: :Test/_files/{fixture_name)_rollback.php for every fixture
- B. Add annotation @magentoApplsolation enabled to method PHPDoc
- C. Modify method PHPDoc and change annotation @magentoDbIsolation to enabled
Answer: C
Explanation:
Explanation
The issue here is that the database storage is not being fully cleaned after the test is run. The solution is to modify the method PHPDoc and change the annotation @magentoDbIsolation to enabled. This will ensure that the database storage is fully cleaned after the test is run. References:

NEW QUESTION # 20
A representative of a small business needs an Adobe Commerce Architect to design a custom integration of a third-party payment solution. They want to reduce the list of controls identified in their Self-Assessment Questionnaire as much as possible to achieve PCI compliance for their existing Magento application.
Which approach meets the business needs?
- A. Utilize the payment provider iframe system to isolate content of the embedded frame from the parent web page.
- B. Utilize the Advanced Encryption standard (aes-256) algorithm to encrypt all customer-sensitive data from the payment module.
- C. Utilize a trusted signed certificate issued by a Certification Authority (CA) to secure each connection made by the payment solution protocol via https.
Answer: A
Explanation:
Explanation
Using an iframe system for payment integration can help reduce the PCI scope and compliance burden for the merchant, as the payment data is collected and processed by the payment service provider (PSP) within the iframe, without touching the merchant's website or server. This way, the merchant can leverage the PSP's PCI certification and avoid storing or transmitting any sensitive cardholder data on their own system. The iframe also provides a secure barrier between the host webpage and the loaded page, preventing any access or manipulation of the payment data by malicious actors. To implement this approach, the merchant needs to embed the PSP's payment form in their checkout page using an iframe element, and configure the communication between the iframe and the host page using JavaScript123.
NEW QUESTION # 21
A company wants to build an Adobe Commerce website to sell their products to customers in their country.
The taxes in their country are highly complex and require customization to Adobe Commerce. An Architect is trying to solve this problem by creating a custom tax calculator that will handle the calculation of taxes for all orders in Adobe Commerce.
Following best practices, how should the Architect add the taxes for all orders?
- A. Write a before plugin to \Magento\Quote\Model\QuoteManagement::placeOrder() and add the custom tax to the quote
- B. Add a new observer to the event sales.quote.collecLtotals.before'' and add the custom tax to the quote
- C. Declare a new total collector in "etc/sales.xmr in a custom module
Answer: C
Explanation:
Explanation
According to the Adobe Commerce documentation, the best way to add a custom tax calculation to all orders is to declare a new total collector in the "etc/sales.xml" file of a custom module. This way, the custom tax logic can be implemented in a separate class that extends the
\Magento\Quote\Model\Quote\Address\Total\AbstractTotal class and overrides the collect() and fetch() methods. The collect() method is responsible for calculating the tax amount and adding it to the quote address, while the fetch() method is responsible for displaying the tax amount in the cart and checkout pages. The new total collector can be assigned to any area of the order totals, such as before or after the subtotal, shipping, or grand total.

NEW QUESTION # 22
An Adobe Commerce Architect is asked by a merchant using B2B features to help with a configuration issue.
The Architect creates a test Company Account and wants to create Approval Rules for orders. The Approval Rules tab does not appear in the Company section in the Customer Account Menu when the Architect logs in using the Company Administrator account.
Which two steps must be taken to fix this issue? (Choose two.)
- A. Set 'Enable B2B Quote' in the B2B Admin to TRUE
- B. Set 'Enable Purchase Orders' in the B2B Admin to TRUE
- C. Set 'Enable Purchase Orders' on the Company Record to TRUE
- D. Merchant needs to log out of frontend and then log back in to load new permissions
- E. Make sure that the 'Purchase Order' payment method is active
Answer: B,E
Explanation:
Explanation
The issue here is that the Approval Rules tab does not appear in the Company section in the Customer Account Menu when the Architect logs in using the Company Administrator account. This is because the Approval Rules feature requires two settings to be enabled: the Purchase Orders feature and the Purchase Order payment method. The solution is to set 'Enable Purchase Orders' in the B2B Admin to TRUE and make sure that the
'Purchase Order' payment method is active. This will allow the Architect to create and manage Approval Rules for orders.

NEW QUESTION # 23
A client has multiple warehouses where orders can be fulfilled. The cost of shipping goods from each warehouse varies by day, due to the number of workers available. The Architect needs to make sure that when an order is shipped, it is shipped from the lowest cost warehouse that is open.
How should this functionality be implemented?
- A. Create a new class implementing
Magento\invtntorysourceSelectionApi\Modei\sourceSelectioninterfacece. which returns open warehouses sorted by cost. - B. Create anew class as a preference for
Magento\inventoryShipping\piugin\Sales\shipment\AssignSourceCodeToShipmentPlugin to set the lowest-cost warehouse on a shipment. - C. Create an after plugin OnHagento\InventoryDistanceBasedSourceSelection\Hodel\Algorithms\DistanceBasedAlgorithto sortto Warehouse sources by cost
Answer: A
Explanation:
Explanation
According to the Adobe Commerce documentation, the Source Selection Interface is the main interface for implementing custom source selection algorithms. The interface defines a method called execute(), which takes a list of items to be shipped and a stock ID as parameters, and returns a SourceSelectionResultInterface object, which contains the recommended sources and quantities for each item. The Architect can create a new class that implements this interface and provides the logic for finding the lowest-cost warehouse that is open for each item. The Architect can then register the new class as an option for the source selection algorithm in the di.xml file of the custom module.

NEW QUESTION # 24
While developing a new functionality for a website in developer mode with all cache types enabled, an Adobe Commerce Developer needs to add \Magento\Sales\Model\Service\InvoiceService SinvoiceService as a new dependency to an existing page action controller in Vendor\CustomModule\Controller\Index\Index . This is accomplished as follows:
After cleaning the f ull_page cache and reloading the page, the developer encounters the following exception:
Recoverable Error: Argument 2 passed to Vendor\CustomModule\Controller\Index\Index::__construct() must be an instance of
\Magento\Sales\Model\Service\InvoiceService [...]
Which action should the Architect recommend to the developer to fix this error?
- A. Remove the generated Child ClaSS from generated/code/Vendor/CustomModule/Controller/Index/Index.
- B. Add the new \Magento\sales\Model\service\invoiceService Sinvoiceservice dependency at the end of the constructor signature.
- C. Clean the block_html cache along with full_page cache.
Answer: A
Explanation:
Explanation
The error is caused by the generated child class not being updated with the new dependency. Removing the generated child class will allow the system to generate a new child class with the correct dependency. The generated child class is a proxy class that extends the original controller class and overrides the constructor to inject the dependencies using the object manager. The generated child class is created when the system runs in developer mode with cache enabled, to avoid performance issues. However, when a new dependency is added to the original controller class, the generated child class does not reflect the change and causes a mismatch in the constructor arguments. Therefore, deleting the generated child class from the generated/code directory will solve the problem.

NEW QUESTION # 25
An Architect agrees to improve company coding standards and discourage using Helper classes in the code by introducing a new check with PHPCS.
The Architect creates the following:
* A new composer package under the AwesomeAgency\CodingStandard\ namespace
* The ruleset. xml file extending the Magento 2 Coding Standard
What should the Architect do to implement the new code rule?
- A.
- B.
- C.
Answer: A
Explanation:
Explanation
Option C is correct because adjusting the ruleset.xml file with the new rule is the simplest and most effective way to implement the new code rule. The ruleset.xml file defines the coding standards that are applied by PHP_CodeSniffer. By extending the Magento 2 Coding Standard and adding a new rule, the Architect can customize the code analysis and enforce the company coding standards. The new rule can use the Magento2.Namespaces.ForbiddenNamespaces sniff to check for any usage of Helper classes in the code and report them as errors or warnings1.
Option A is incorrect because creating a new composer package under the AwesomeAgency\CodingStandard\ namespace is not enough to implement the new code rule. The composer package is just a way to distribute and install the coding standard, but it does not define the rules themselves. The Architect still needs to create a ruleset.xml file and register it with PHP_CodeSniffer2.
Option B is incorrect because creating a new class
\AwesomeAgency\CodingStandard\Ruleset\ForbiddenNamespaces and specifying the rule inside the process method is unnecessary and complicated. The Architect does not need to create a new class or a new sniff for this rule, as there is already an existing sniff in the Magento 2 Coding Standard that can be used for this purpose. The Magento2.Namespaces.ForbiddenNamespaces sniff can be configured with an include-pattern element to specify which namespaces are forbidden1.

NEW QUESTION # 26
While reviewing a newly developed pull request that refactors multiple custom payment methods, the Architect notices multiple classes that depend on \Magento\Framework\Encryption\EncryptorInterface to decrypt credentials for sensitive data. The code that is commonly repeated is as follows:
The Architect needs to recommend an optimal solution to avoid redundant dependency and duplicate code among the methods. Which solution should the Architect recommend?
- A. Replace all Vendor\PaymentModule\Gateway\Config\Config ClaSSeS With virtualType Of Magento\Payiaent\Gateway\Conf ig\Conf ig and Set <user_secret backend_Model="Magento\Config\Model\Config\Backend\Encrypted" /> Under config.xml
- B. Add a plugin after the getvalue method of $scopeConfig, remove the $encryptor from dependency and use it in the plugin to decrypt the value if the config name is user.secret'
- C. Create a common config service class vendor\Pay-ient\Gateway\conf ig\conf ig under Vendor.Payment and use it as a parent class for all of the Vendor\PayimentModule\Gateway\Conf ig\Conf ig ClaSSeS and remove $scopeConf ig and Sencryptor dependencies
Answer: A
Explanation:
Explanation
The Architect should recommend replacing all Vendor\PaymentModule\Gateway\Config\Config Classes with virtualType of Magento\Payment\Gateway\Config\Config and setting <user_secret backend_Model="Magento\Config\Model\Config\Backend\Encrypted" /> under config.xml. This will avoid redundant dependency and duplicate code among the methods. The virtualType of Magento\Payment\Gateway\Config\Config will inherit the functionality of the base class and allow the customization of the constructor arguments, such as the pathPattern and valueHandlerPool. The backend_Model attribute of the user_secret field will specify that the value of this field should be encrypted and decrypted by the Magento\Config\Model\Config\Backend\Encrypted class, which implements the
\Magento\Framework\App\Config\ValueInterface interface and uses the
\Magento\Framework\Encryption\EncryptorInterfaceinternally12. This way, the payment modules do not need to depend on the \Magento\Framework\Encryption\EncryptorInterface or the
\Magento\Framework\App\Config\ScopeConfigInterface directly, and can use the getValue method of the Magento\Payment\Gateway\Config\Config class to get the decrypted value of the user_secret field3.

NEW QUESTION # 27
An Adobe Commerce Architect is investigating a case where some EAV product attributes are no longer updated.
* The catalog is composed of 20.000 products with 100 attributes each.
* The product updates are run by recurring Adobe commerce imports that happen multiple times a day.
* The Architect finds an error in the logs that indicates an integrity constraint while trying to insert row with id
2147483647.
What is causing this error?
- A. Integrity constraints were dropped after upgrading to the latest version, and the integrity checks were missed.
- B. Magento framework uses INSERT on DUPLICATE, which leads to reaching the max limit of the increment of the column.
- C. EAV attribute import uses REPLACE, which leads to reaching the max limit of the increment of the column
Answer: C
Explanation:
Explanation
EAV attribute import uses the REPLACE statement, which deletes and inserts a new row with the same primary key value. This causes the auto-increment column to increase by one for each row, even if the row already exists. If the auto-increment column reaches its maximum value, which is 2147483647 for a signed INT, then any further REPLACE statement will fail with an integrity constraint violation error. References:

NEW QUESTION # 28
An Adobe Commerce Architect creates a stopword for the Italian locale named stopwordsjtJT.csv and changes the stopword directory to the following: <magento_root>/app/code/Customvendor/Elasticsearch/etc/stopwords/ What is the correct approach to change the stopwords directory inside the custom module?
- A. Add stopwords to the stopwordsDirectory parameter of the\Hagento\Elasticsearch\Model\Adapter\Document\DirectoryBuilder ClaSS Via stopwords/it.xml and Adobe Commerce will automatically detect the current module.
- B. Add stopwords to the stopwordsDirectory and CustomerVendor_Elasticsearch to the stopword sModule parameter Of the \Magento\Elasticsearch\SearchAdapter\Query\Preprocessor\Stopwords ClflSS Via di.xml
- C. Add a new ClaSS implementing \Magento\Framework\Setup\Patch\PatchInterface to modify the default Value Of elasticsearch\customer\stopwordspath in core.conf ig_data table.
Answer: B
Explanation:
Explanation
According to the Adobe Commerce documentation, the correct approach to change the stopwords directory inside a custom module is to use dependency injection to override the default values of the stopwordsDirectory and stopwordsModule parameters of the
\Magento\Elasticsearch\SearchAdapter\Query\Preprocessor\Stopwords class. The stopwordsDirectory parameter specifies the relative path of the stopwords directory from the module directory, while the stopwordsModule parameter specifies the name of the module that contains the stopwords directory. By adding these parameters to the di.xml file of the custom module, the Architect can change the location of the stopwords files without modifying the core code or database.

NEW QUESTION # 29
An Adobe Commerce Architect needs to log the result of a ServiceClass:: getData method execution after all plugins have executed. The method is public, and there are a few plugins declared for this method. Among those plugins are after and around types, and all have sortOrder specified.
Which solution should be used to meet this requirement?
- A. Declare a new plugin with the sortOrder value higher than the highest declared plugin sortOrder and implement afterGetData method.
- B. Declare a new plugin with the sortOrder value higher than the highest declared plugin sortOrder and implement aroundGetData method.
- C. Declare a new plugin with the sortOrder value lower than the lowest declared plugin sortOrder and implement aroundGetData method.
Answer: A
Explanation:
Explanation
This solution ensures that the new plugin will execute after all the existing plugins for the ServiceClass::getData method, and will be able to log the final result of the method execution. The afterGetData method of the new plugin will receive the result of the method as a parameter, and can use any logging mechanism to record it. The sortOrder value of the new plugin should be higher than the highest declared plugin sortOrder, so that it will run last in the sequence of plugins. The after type of plugin is preferred over the around type of plugin, because it is simpler and more efficient, and does not require calling the proceed() method.
