NEW QUESTION # 22
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 aroundGetData method.
- B. Declare a new plugin with the sortOrder value higher than the highest declared plugin sortOrder and implement afterGetData method.
- C. Declare a new plugin with the sortOrder value lower than the lowest declared plugin sortOrder and implement aroundGetData method.
Answer: B
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.

NEW QUESTION # 23
An Adobe Commerce Architect designs a data flow that contains a new product type with its own custom pricing logic to meet a merchant requirement. Which three steps are required when adding a product type with custom pricing? (Choose three.)
- A. Hydrator for attributes belonging to the new product type
- B. New price model extending \Magento\Catalog\Model\Product\Type\Price
- C. Custom type model extended from the abstract Product Type model
- D. A new class with custom pricing logic, extending the abstract Product model class
- E. Content of the etc/product_types.xml file
- F. Data patch to register the new product type
Answer: B,C,E
Explanation:
Explanation
To add a product type with custom pricing, the Architect needs to do the following steps:
Create a content of the etc/product_types.xml file that defines the new product type, its label, model, index priority, and price model. This file is used to register the new product type and its associated classes in Magento1.
Create a new price model that extends \Magento\Catalog\Model\Product\Type\Price and implements the custom pricing logic for the new product type. The price model is responsible for calculating the final price of the product based on various factors, such as special price, tier price, catalog price rules, etc2.
Create a custom type model that extends from the abstract Product Type model (\Magento\Catalog\Model\Product\Type\AbstractType) and overrides the methods related to the product type behavior, such as prepareForCart, getAssociatedProducts, etc. The type model defines how the product type interacts with other components, such as quote, order, cart, etc3.

NEW QUESTION # 24
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. 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'
- B. 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
- C. 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
Answer: C
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 # 25
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 # 26
Due to a marketing campaign, a website is experiencing a very large number of simultaneously placed orders, which is affecting checkout performance. The website is in the production deploy mode.
Which two website settings can an Architect optimize to decrease the impact on checkout performance?
(Choose two.)
- A. Asynchronous email notifications admin panel setting (stores > settings > configuration > sales > sales Emails > General settings > Asynchronous) can be enabled
- B. A new database can be created and the Split Database feature can be automatically configured with the following command: bin/Magento setup:db-schema:spiit-sales -host"<checkout db host or ip>-
--dbnanie""<name>" --username"<checkout db username)" --password""<password>" - C. The website deploy mode can be set to siege by executingthe following CLI command: bin/Magento deploy:mode:set siege, provided that it will be changed back to production as soon as the number of simultaneously placed orders decreases to acceptable levels
- D. Multithreaded checkout processing admin panel setting (stores > settings > configuration > sales > checkout > General settings > Asynchronous) can be set to a higher value representing the number of PHP threads used exclusively for checkout
- E. Asynchronous indexing admin panel Setting (Stores > Settings > Configuration > Advanced> Developer
> Grid Settings > Asynchronous indexing) can be enabled by executing the following CLI Command:
bin/Magento config:set dev/grid/async_indexing 1
Answer: B,E
Explanation:
Explanation
Option A is correct because enabling asynchronous indexing can improve the checkout performance by reducing the database load and avoiding locking issues. Asynchronous indexing allows the indexers to run in the background without affecting the frontend operations. The command bin/magento config:set dev/grid/async_indexing 1 can be used to enable this option in the production mode1.
Option C is correct because creating a new database and splitting the sales tables can also improve the checkout performance by distributing the database load and avoiding contention. Splitting the database allows the checkout and order management operations to use a separate master database from the rest of the Magento application tables. The command bin/magento setup:db-schema:split-sales
--host="<checkout db host or ip>" --dbname="<name>" --username="<checkout db username>"
--password="<password>" can be used to configure this feature2.
Option B is incorrect because enabling asynchronous email notifications does not affect the checkout performance directly. Asynchronous email notifications allow the order confirmation emails to be sent in batches by a cron job instead of immediately after placing an order. This option can reduce the server load and improve the customer experience, but it does not impact the checkout process itself3.
Option D is incorrect because there is no such deploy mode as siege in Magento 2. The available deploy modes are default, developer, and production. Changing the deploy mode can affect the performance, caching, and error handling of the Magento application, but it does not directly affect the checkout performance4.
Option E is incorrect because there is no such admin panel setting as multithreaded checkout processing in Magento 2. The number of PHP threads used for checkout is determined by the web server configuration and the PHP-FPM settings, not by the Magento application settings. Increasing the number of PHP threads may improve thecheckout performance, but it also requires more server resources and may cause other issues5.

NEW QUESTION # 27
A custom cron job has been added to an Adobe Commerce system to collect data for several reports. Its crontab. xml configuration is as follows:
The job is data intensive and runs for between 20 and 30 minutes each night.
Within a few days of deployment, it is noticed that the sites sitemap. xml file has not been updated since the new job was added.
What should be done to fix this issue?
- A. Break the data gathering job into a number of smaller jobs, so that each individual job runs for a maximum of 5 minutes
- B. Create a new cron group for the reporting job, specifying
<use_separate_process>i</use_separate_process> - C. Change the schedule of the siten.aP_generate cron job to 30 0 * * *so that it runs after the gather_reporting_data job has completed.
Answer: B
Explanation:
Explanation
The issue here is that the gather_reporting_data job is running for a long time and blocking the sitemap_generate job from running. The solution is to create a new cron group for the reporting job and specify <use_separate_process>i</use_separate_process> so that the reporting job runs in a separate process and does not block the sitemap_generate job.

NEW QUESTION # 28
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. EAV attribute import uses REPLACE, which leads to reaching the max limit of the increment of the column
- B. Integrity constraints were dropped after upgrading to the latest version, and the integrity checks were missed.
- C. Magento framework uses INSERT on DUPLICATE, which leads to reaching the max limit of the increment of the column.
Answer: A
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 # 29
An Adobe Commerce Architect runs the PHP Mess Detector from the command-line interface using the coding standard provided with Adobe Commerce. The following output appears:
The Architect looks at the class and notices that the constructor has 15 parameters. Five of these parameters are scalars configuring the behavior of MyService. The class also contains three constants referencing one other class.
How should the Architect fix the code so that it complies with the coding standard rule?
- A. Modify the code of MyService so that the number of different classes and interfaces referenced anywhere inside the class is fewer than 13.
- B. Consolidate the constants referencing other classes into a string representation.
- C. Introduce a new class accepting those five scalars and use it in the constructor and the remaining logic of MyService.
Answer: C
Explanation:
Explanation
The issue is being caused by the high coupling between objects (CBO) value of the class MyService. CBO is a metric that measures the number of classes that are coupled to a given class, either by method calls, property or parameter references, inheritance, or constants1. A high CBO value indicates that the class is too tightly coupled with other classes, which makes it more difficult to maintain, test, and reuse2. To reduce the CBO value, the Architect should introduce a new class that encapsulates the five scalar parameters that configure the behavior of MyService. This way, the constructor of MyService will only have one parameter of the new class type, instead of five scalar parameters. This will also make the code more readable and maintainable, as the new class can provide methods to access and manipulate the configuration data. The constants referencing other classes should not be consolidated into a string representation, as this would not reduce the CBO value and would make the code less clear and type-safe3. The number of different classes and interfaces referenced anywhere inside the class is not relevant for the CBO metric, as it only counts the classes that are coupled to the given class1.

NEW QUESTION # 30
An Adobe Commerce Architect is working on a scanner that will pull prices from multiple external product feeds. The Architect has a list of vendors and decides to create new config file marketplace.feeds.xml.
Which three steps can the Architect take to ensure validation of the configuration files with unique validation rules for the individual and merged files? (Choose three.)
- A. Add the Uniform Resource Name to the XSD file in the config XML file.
- B. Implement validation rules in the Converter class for the Config Reader
- C. Create a class that implements \Magento\Framework\Config\Datainterface.
- D. Provide schema to validate a merged file.
- E. Create validation rules in marketplace.schema.xsd.
- F. Provide schema to validate an individual file.
Answer: D,E,F
Explanation:
Explanation
The Architect can take the following steps to ensure validation of the configuration files with unique validation rules for the individual and merged files:
Create validation rules in marketplace.schema.xsd. This file defines the structure and constraints of the XML elements and attributes for the marketplace.feeds.xml configuration file. The Architect can use this file to specify the required and optional elements, data types, values, and patterns for the configuration file.
Provide schema to validate a merged file. This schema is used to validate the final configuration file that is generated after merging all the individual configuration files from different modules. The Architect can use this schema to check the consistency and completeness of the merged configuration file.
Provide schema to validate an individual file. This schema is used to validate each individual configuration file from each module before merging them. The Architect can use this schema to check the syntax and validity of each configuration file.

NEW QUESTION # 31
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 Advanced Encryption standard (aes-256) algorithm to encrypt all customer-sensitive data from the payment module.
- B. Utilize the payment provider iframe system to isolate content of the embedded frame from the parent web page.
- 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: B
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 # 32
An Adobe Commerce Architect is reviewing API-functional test code. Some tests send errors to indicate that the customer address does not exist. The test codes show the following:
Which step should the Architect take to fix the test errors?
- A. Set the annotation to USe AmagentoPersistDataFixture Magento/Cu5tomer/_f iles/custcwer_one_address.php instead Of @magentoDataFixture Magento/Customer/_f iles/customer_one_address.php
- B. Change the annotation to Use@magentoApiDataFixture Magento/Customer/_files/ instead Or dmagentoDataFixture Magento/Customer/_files/customer_one_address.php
- C. Update the annotation to Specify addreSSjd EniagentoDataFixture Magento/Customer/_files/customer_one_address.php with:{Maddress_id":"$address.id$"}
Answer: A
Explanation:
Explanation
The issue is being caused by the use of @magentoDataFixture annotation, which creates a temporary data fixture that is rolled back after each test execution1. This means that the customer address created by the fixture is not persisted in the database and cannot be retrieved by subsequent tests. To fix this, the Architect should use @magentoPersistDataFixture annotation, which creates a permanent data fixture that is not rolled back after each test execution2. This way, the customer address created by the fixture will be persisted in the database and can be accessed by subsequent tests. Changing the annotation to use @magentoApiDataFixture or specifying address_id in the annotation will not solve the issue, as they are not related to the persistence of the data fixture3. References: Data fixtures, Persistent data fixtures, API-functional tests
NEW QUESTION # 33
A merchant notices that product price changes do not update on the storefront.
The index management page in the Adobe Commerce Admin Panel shows the following:
* All indexes are set to 'update by schedule'
* Their status is 'ready'
* There are no items in the backlog
* The indexes were last updated 1 minute ago
A developer verifies that updating and saving product prices adds the relevant product IDs into the catalog_product_price_cl changelog table. Which two steps should the Architect recommend to the developer to resolve this issue? (Choose two.)
- A. Make sure that no custom or third-party modules modify the changelog and indexing process.
- B. Make sure that the version_id for the price indexer in the mview_state table is not higher than the last entry for the same column in the changelog table and re-synchronize.
- C. Invalidate the catalog_Product_price indexer in the Adobe Commerce Admin Panel so that it is fully reindexed next time the cron runs.
- D. Manually reindex the catalog_product_price index from the command line: bin/magento indexer:reindex catalog_product_price.
- E. Reduce the frequency of the cron job to 5 minutes so the items have more time to process.
Answer: A,B
Explanation:
Explanation
The issue here is that the product price changes are not reflected on the storefront, even though the indexes are set to update by schedule and there are no items in the backlog. This indicates that there might be some problem with the changelog and indexing process, which are responsible for tracking and applying the data changes to the index tables. Therefore, the Architect should recommend the developer to check if any custom or third-party modules interfere with the changelog and indexing process, and disable or fix them if needed.
Additionally, the Architect should recommend the developer to verify that the version_id for the price indexer in the mview_state table is consistent with the last entry for the same column in the changelog table, and re-synchronize them if they are out of sync. This will ensure that the indexer can process all the data changes correctly and update the index tables accordingly. References:

NEW QUESTION # 34
In a custom module, an Architect wants to define a new xml configuration file. The module should be able to read all the xml configuration files declared in the system, merge them together, and use their values in PHP class.
Which two steps should the Architect make to meet this requirement? (Choose two.)
- A. Inject a "reader" dependency for "Magento\Framework\Config\Data" in di.xml
- B. Write a plugin for \Magento\Framework\Config\Data::get() and read the custom xml files
- C. Create a Data class that implements "\Magento\Framework\Config\Data"
- D. Append the custom xml file name in "Magento\Config\Model\Config\Structure\Reader" in di.xml
- E. Make a Reader class that implements '\Magento\Framework\Config\Reader\Filesystem"
Answer: C,E
Explanation:
Explanation
According to the Adobe Commerce documentation, to create a new xml configuration file, the Architect needs to create a Data class and a Reader class for the custom module. The Data class is responsible for storing and retrieving the configuration data from the cache or the Reader class. The Data class should implement the
"\Magento\Framework\Config\Data" interface or extend the "\Magento\Framework\Config\Data" class. The Reader class is responsible for reading and validating the xml configuration files from the file system. The Reader class should implement the '\Magento\Framework\Config\Reader\Filesystem" interface or extend the
'\Magento\Framework\Config\Reader\Filesystem" class. The Architect also needs to declare the Data class and the Reader class in the di.xml file of the custom module, and specify the name of the xml configuration file, the converter class, and the schema locator class for the Reader class.

NEW QUESTION # 35
A merchant is utilizing an out-of-the-box Adobe Commerce application and asks to add a new reward card functionality for customers. During the code review, the Adobe Commerce Architect notices the reward_card_number attribute setup created for this functionality is causing the customer attribute to be unavailable in the My account/My rewards page template.
What should be added to set the customer attribute correctly?
- A. scope property should be added with a value of global
- B. group property should be added with a value of 1
- C. system property should be added with a value of true
Answer: B
Explanation:
Explanation
The group property determines which section of the customer account the attribute belongs to. By setting the group property to 1, the reward_card_number attribute will be assigned to the default group, which is the Account Information section. This will make the attribute available in the My account/My rewards page template. References:

NEW QUESTION # 36
A third-party company needs to create an application that will integrate the Adobe Commerce system to get orders data for reporting. The integration needs access to the GET /Vl/orders endpoint. It will call this endpoint automatically every hour around the clock. The merchant wants the ability to restrict or extend access to resources as well as to revoke the access using Admin Panel.
Which type of authentication available in Adobe Commerce should be used and implemented in a third-party system for this integration?
- A. Use OAuth-based authentication to provide access to system resources. Integration will be registered by the merchant in the admin panel with an OAuth handshake during activation. The third-party system should follow OAuth protocol to authorize.
- B. Use token-based authentication to obtain the Admin Token. The third-party system will utilize the REST endpoint using the admin username and password to get the Admin Token, which will be used as the Bearer Token to authorize.
- C. Use token-based authentication to obtain an integration Token, integration will be created and activated in the admin panel using default integration token settings to get access to the token, which will be used as the Bearer Token to authorize.
Answer: A
Explanation:
Explanation
According to the Adobe Commerce documentation, OAuth-based authentication is the recommended method for integrations that need access to system resources, such as orders, customers, products, etc. OAuth-based authentication allows the merchant to control the access level and scope of the integration, as well as to revoke the access at any time using the admin panel. OAuth-based authentication also requires an OAuth handshake between the integration and the Adobe Commerce system during activation, which ensures a secure exchange of tokens and keys. The third-party system should follow the OAuth protocol to obtain and refresh the access token, which will be used as the Bearer Token to authorize the REST API calls.

NEW QUESTION # 37
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 Purchase Orders' on the Company Record to TRUE
- B. Merchant needs to log out of frontend and then log back in to load new permissions
- C. Make sure that the 'Purchase Order' payment method is active
- D. Set 'Enable B2B Quote' in the B2B Admin to TRUE
- E. Set 'Enable Purchase Orders' in the B2B Admin to TRUE
Answer: C,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.
