NEW QUESTION # 14
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. Create a class that implements \Magento\Framework\Config\Datainterface.
• B. Implement validation rules in the Converter class for the Config Reader
• C. Create validation rules in marketplace.schema.xsd.
• D. Provide schema to validate an individual file.
• E. Add the Uniform Resource Name to the XSD file in the config XML file.
• F. Provide schema to validate a merged file.

Answer: C,D,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 # 15
An Adobe Commerce Architect notices that queue consumers close TCP connections too often on Adobe Commerce Cloud server leading to delays in processing messages.
The Architect needs to make sure that consumers do not terminate after processing available messages in the queue when CRON job is running these consumers.
How should the Architect meet this requirement?

• A. Increase multiple_process limit to spawn more processes for each consumer
• B. Change max_messages from 10,000 to 1,000 for CRON_CONSUMERS_RUNNER variable.
• C. Set cohsumers_wait_for_max_MESSAGES variable true in deployment stage.

Answer: C

Explanation:
Explanation
Option A is correct because setting the consumers_wait_for_max_messages variable true in the deployment stage is the best way to meet the requirement. This variablecontrols whether the queue consumers should wait for a maximum number of messages to process before terminating. If this variable is set to true, the consumers will not terminate after processing the available messages in the queue, but will wait until they reach the max_messages limit or the cron job timeout. This way, the consumers can keep the TCP connections open and avoid delays in processing messages1.
Option B is incorrect because increasing the multiple_process limit to spawn more processes for each consumer will not solve the issue of queue consumers closing TCP connections too often. The multiple_process limit determines how many parallel processes can be run for each consumer.
Increasing this limit may improve the throughput of message processing, but it will also consume more server resources and may cause conflicts or errors. Moreover, it will not prevent the consumers from terminating after processing the available messages in the queue2.
Option C is incorrect because changing the max_messages from 10,000 to 1,000 for CRON_CONSUMERS_RUNNER variable will worsen the issue of queue consumers closing TCP connections too often. The max_messages variable defines how many messages each consumer should process before terminating. Decreasing this variable will make the consumers terminate more frequently, which will result in more TCP connections being closed and reopened. This will increase the delays in processing messages3.

NEW QUESTION # 16
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. system property should be added with a value of true
• C. group property should be added with a value of 1

Answer: C

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 # 17
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. Custom type model extended from the abstract Product Type model
• B. New price model extending \Magento\Catalog\Model\Product\Type\Price
• C. Content of the etc/product_types.xml file
• D. Hydrator for attributes belonging to the new product type
• E. A new class with custom pricing logic, extending the abstract Product model class
• F. Data patch to register the new product type

Answer: A,B,C

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 # 18
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. Execute Command config:set export/customr/files_directory /var/releases/{release_nunber} toSet the new export path.
• B. Doable Crontab before deployment and re-launch after deployment.
• C. Restart the consumer process during deployment to use the directory with a new application version for export files.

Answer: A

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 # 19
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. 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
• B. Specify a @cacgecacheable(cacheable: false) directive for each GraphQL query, making sure that the data returned is not cached, and is up to date
• C. 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.

Answer: A

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 # 20
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. Modify method PHPDoc and change annotation @magentoDbIsolation to enabled
• B. Add annotation @magentoApplsolation enabled to method PHPDoc
• C. Create Customer_ProductType: :Test/_files/{fixture_name)_rollback.php for every fixture

Answer: A

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:
https://developer.adobe.com/commerce/testing/guide/integration/#database-isolation1

NEW QUESTION # 21
A client is migrating to Adobe Commerce Cloud and has approximately 800 existing redirects that must be implemented. The number of redirects cannot be reduced because all redirects are specific, and do not match any pattern.
How should the redirects be configured to ensure performance?

• A. Use VCL snippets to offload the redirect to Fastly.
• B. Add each redirect in the magento/routes.yaml file.
• C. Add each redirect as a URL rewrite via the admin Ul.

Answer: A

Explanation:
Explanation
Option B is correct because using VCL snippets to offload the redirect to Fastly is the best way to configure the redirects and ensure performance. VCL snippets are custom code segments that can be added to the Fastly configuration to modify the behavior of the caching service. By using VCL snippets, the redirects can be handled at the edge server level, without reaching the Magento application or the database. This reduces the server load and improves the response time for the redirected requests1.
Option A is incorrect because adding each redirect in the magento/routes.yaml file is not a recommended way to configure the redirects. The magento/routes.yaml file is used to define custom routes for Magento Cloud projects, such as mapping domains or subdomains to environments or services. Adding redirects in this file can cause conflicts with the existing routes and affect the routing logic of the project2.
Option C is incorrect because adding each redirect as a URL rewrite via the admin UI is not an optimal way to configure the redirects. The URL rewrite feature in Magento allows creating custom URLs for products, categories, and CMS pages, and redirecting them to their canonical URLs. However, adding a large number of URL rewrites can increase the database size and affect the performance of the Magento application. Moreover, using the admin UI for this task can be tedious and error-prone3.

NEW QUESTION # 22
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. 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. 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'

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 # 23
An Adobe Commerce Architect is supporting deployment and building tools for on-premises Adobe Commerce projects. The tool is executing build scripts on a centralized server and using an SSH connection to deploy to project servers.
A client reports that users cannot work with Admin Panel because the site breaks every time they change interface locale.
Considering maintainability, which solution should the Architect implement?

• A. Edit project env.php file, configure 'adminJocales_for_build' value, and specify all required locales
• B. Adjust the tools build script and specify required locales during *setup:static-content:deploy' command
• C. Modify project config.php file, configure 'admin_locales_for_deploy' value, and specify all required locales

Answer: B

Explanation:
Explanation
The issue here is that the site breaks every time the users change interface locale in the Admin Panel. This is because the static content for the different locales is not generated during the deployment process. The solution is to adjust the tools build script and specify required locales during *setup:static-content:deploy' command. This will ensure that the static content for all the needed locales is generated and deployed to the project servers. References:
https://experienceleague.adobe.com/docs/commerce-cloud-service/user-guide/develop/deploy/static-content.htm

NEW QUESTION # 24
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. GraphQL requests are always run against the default store view unless a store header or store cookie is provided.
• B. $_server["mage_run_cooe") needs to be setto store and *$_SERVER["MAGE_RUN_TYPE"] needs to be set to the store code instead.
• C. The magento-vars.php file is not processed for any GraphQL requests, so the default website is always processed.

Answer: A

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 # 25
A merchant asks for a new category attribute to allow uploading an additional mobile image against categories. The merchant utilizes the content staging and preview feature in Adobe Commerce and wants to schedule and review changes to this new mobile image field.
A developer creates the attribute via a data patch and adds it to view/adminhtml/ui_component/category_f orm. xml. The attribute appears against the category in the main form, but does not appear in the additional form when scheduled updates are made.
To change this attribute when scheduling new category updates, which additional action should the Architect ask the developer to take?

• A. The attribute must have <item- name=''allow_staging" xsi:type=''boolean''>true</item> set in the cjt.gopy_for-.xni file under the attributes config' section.
• B. The attribute must have its apply_to field set to "staging" in the data patch file.
• C. The attribute must also be added to view/adminhtml/ui_co-component/catalogstaging_category_update_form.xml.

Answer: C

Explanation:
Explanation
This action is necessary to make the attribute available for content staging and preview. According to the Adobe Commerce documentation, the catalogstaging_category_update_form.xml file defines the fields that are displayed in the Scheduled Changes section of the category form. The file extends the category_form.xml file and adds additional fields that are specific to content staging, such as start and end dates, campaign name, description, etc. To include a custom category attribute in the Scheduled Changes section, the attribute must also be declared in the catalogstaging_category_update_form.xml file with the same configuration as in the category_form.xml file.

NEW QUESTION # 27
An Adobe Commerce Architect notices that the product price index takes too long to execute. The store is configured with multiple websites and dozens of customer groups.
Which two ways can the Architect shorten the full price index execution time? (Choose two.)

• A. Set mage_ihdexer_threads_COUNT environment variable to enable parallel mode
• B. Move catalog_Price_index indexer to another custom indexer group
• C. Edit customer groups to exclude websites that they are not using
• D. Set Customer Share Customer Accounts Option to Global
• E. Enable price index customer group merging for products without tier prices

Answer: A,E

Explanation:
Explanation
The product price index can be optimized by using parallel mode and customer group merging. Parallel mode allows the indexer to run multiple threads simultaneously, which can speed up the indexing process. Customer group merging reduces the number of rows in the price index table by merging customer groups that have the same product prices. This can improve the performance of the price index queries and reduce the index size. References: Indexing optimization, Price index customer group merging

NEW QUESTION # 28
An Adobe Commerce Architect needs to create a new customer segment condition to enable admins to specify an Average sales amount' condition for certain segments.
The Architect develops the custom condition under
Vendor\Module\Model\Segment\Condition\AverageSalesAmount with all of its requirements:

During testing, the following error appears:

What should the Architect do to fix the problem?

• A.
• B.
• C.

Answer: A

Explanation:
Explanation
The error is caused by the missing class declaration for the custom condition class. According to the Adobe Commerce documentation, to create a custom customer segment condition, the class must extend the
\Magento\CustomerSegment\Model\Condition\AbstractCondition class and implement the
\Magento\CustomerSegment\Model\Condition\Combine\Interface interface. The class must also declare its name, label, value type, and attribute code properties. Option B is the only option that correctly declares the class with the required properties and inheritance. Option A and Option C are incorrect because they do not extend the AbstractCondition class or implement the CombineInterface interface, and they do not declare the name, label, value type, or attribute code properties.

NEW QUESTION # 29
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. Merchant needs to log out of frontend and then log back in to load new permissions
• B. Set 'Enable B2B Quote' in the B2B Admin to TRUE
• C. Make sure that the 'Purchase Order' payment method is active
• D. Set 'Enable Purchase Orders' on the Company Record 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.

NEW QUESTION # 30
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. Add the new \Magento\sales\Model\service\invoiceService Sinvoiceservice dependency at the end of the constructor signature.
• B. Clean the block_html cache along with full_page cache.
• C. Remove the generated Child ClaSS from generated/code/Vendor/CustomModule/Controller/Index/Index.

Answer: C

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 # 31
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 lower than the lowest 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 higher than the highest 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.
