NEW QUESTION # 28
An Adobe Commerce Architect is troubleshooting an issue on an Adobe Commerce Cloud project that is not yet live.
The developers copied the Staging Database to Production in readiness to Go Live. However, when the developers test their Product Import feature, the new products do not appear on the front end.
The developers suspect the Varnish Cache is not being cleared. Staging seems to work as expected. Production was working before the database migration.
What is the likely cause?
- A. Thefatlycredentials in the Production Database are incorrect.
- B. The site URLs in the Production Database are the URLs of the Staging Instance and must be updated
- C. A deployment should have been done on Production to initialize Fatly caching.
Answer: B
NEW QUESTION # 29
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 # 30
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 an after plugin OnHagento\InventoryDistanceBasedSourceSelection\Hodel\Algorithms\DistanceBasedAlgorithto sortto Warehouse sources by cost
- C. Create anew class as a preference for
Magento\inventoryShipping\piugin\Sales\shipment\AssignSourceCodeToShipmentPlugin to set the lowest-cost warehouse on a shipment.
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 # 31
An Architect needs to review a custom product feed export module that a developer created for a merchant.
During final testing before the solution is deployed, the product feed output is verified as correct. All unit and integration tests for code pass.
However, once the solution is deployed to production, the product price values in the feed are incorrect for several products. The products with incorrect data are all currently part of a content staging campaign where their prices have been reduced.
What did the developer do incorrectly that caused the feed output to be incorrect for products in the content staging campaign?
- A. The developer forgot to use the getContentStagingValue method to retrieve the active campaign value of the product data.
- B. The developer retrieved product data directly from the database using the entity_id column rather than a collection or repository.
- C. The developer did not check for an active content staging campaign and emulates the campaign state when retrieving product data.
Answer: C
Explanation:
Explanation
Option C is correct because the developer did not check for an active content staging campaign and emulate the campaign state when retrieving product data. Content staging campaigns can modify the product data such as price, name, description, and so on, based on a schedule. To get the correct product data for a specific date and time, the developer needs to use the Magento\Staging\Model\VersionManager class to set the current version ID and emulate the campaign state1. Otherwise, the product data will be retrieved from the default store view without applying the campaign changes.
Option A is incorrect because retrieving product data directly from the database using the entity_id column is not necessarily wrong. It may not be the best practice, but it does not cause the feed output to be incorrect for products in the content staging campaign. The content staging campaigns are stored in separate tables with a version ID that links to the main product table2. The developer can still join these tables and query the product data based on the version ID and date.
Option B is incorrect because there is no such method as getContentStagingValue in Magento 2. The developer cannot use this method to retrieve the active campaign value of the product data. The correct way to get the product data for a specific campaign is to use the Magento\Staging\Model\VersionManager class as mentioned above.

NEW QUESTION # 32
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 # 33
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 # 34
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. Add each redirect as a URL rewrite via the admin Ul.
- B. Add each redirect in the magento/routes.yaml file.
- C. Use VCL snippets to offload the redirect to Fastly.
Answer: C
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 # 35
An Architect is configuring the preload.keys for Redis on an Adobe Commerce on-premise instance.
The Architect discovers that the following cache keys are loaded on each frontend request:
EAV_ENTITY_TYPES, GLOBAL_PLUGIN_LIST, DB_IS_UP_TO_DATE, SYSTEM_DEFAULT.
* The id_prefix of the frontend => page_cache is set to 063_.
* The id_pref ix of frontend => default is set to 762_.
* The Architect has enabled and configured Redis L2 caching.
How should the preload.keys be configured?
- A.
- B.
- C.
- D.
Answer: C
Explanation:
Explanation
Option C is correct because it configures the preload.keys correctly for Redis L2 caching on an Adobe Commerce on-premise instance. Redis L2 caching is a feature that allows storing the cache data in both Redis and the local file system. This way, the cache data can be loaded faster from the local storage, while Redis acts as a cache invalidation service. To use Redis L2 caching, the backend option for both frontend => page_cache and frontend => default must be set to Magento\Framework\Cache\Backend\RemoteSynchronizedCache1. To enable the preload feature, which reduces the number of requests to Redis, the preload.keys option must be specified with the cache keys that are loaded on each frontend request. However, unlike Redis L1 caching, the preload.keys must include the suffix :hash to indicate that only the hash values of the cache data are stored in Redis2.
Therefore, the correct configuration for preload.keys is:
<preload_keys' => [ '762_EAV_ENTITY_TYPES:hash', '762_GLOBAL_PLUGIN_LIST:hash',
'762_DB_IS_UP_TO_DATE:hash', '762_SYSTEM_DEFAULT:hash', ],
Option A is incorrect because it configures the preload.keys incorrectly for Redis L2 caching. It uses the id_prefix of frontend => page_cache (063_) instead of frontend => default (762_) for the cache keys.
This will cause a mismatch between the cache keys and the cache data, and result in incorrect or missing cache data. Moreover, it does not include the suffix :hash for the preload.keys, which is required for Redis L2 caching2.
Option B is incorrect because it configures the preload.keys incorrectly for Redis L2 caching. It does not include the suffix :hash for the preload.keys, which is required for Redis L2 caching2. It also uses a wrong cache key (GLOBAL_PLUGIN_LIST) instead of GLOBAL_PLUGIN_LIST.
Option D is incorrect because it configures the preload.keys incorrectly for Redis L2 caching. It uses a wrong id_prefix (162_) instead of frontend => default (762_) for the cache keys. This will cause a mismatch between the cache keys and the cache data, and result in incorrect or missing cache data. It also uses a wrong cache key (EAV_ENTITY_TYPES) instead of EAV_ENTITY_TYPES.

NEW QUESTION # 36
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. 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
- 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. 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 - D. Asynchronous email notifications admin panel setting (stores > settings > configuration > sales > sales Emails > General settings > Asynchronous) can be enabled
- E. 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
Answer: B,C
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 # 37
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. Update the annotation to Specify addreSSjd EniagentoDataFixture Magento/Customer/_files/customer_one_address.php with:{Maddress_id":"$address.id$"}
- C. Change the annotation to Use@magentoApiDataFixture Magento/Customer/_files/ instead Or dmagentoDataFixture Magento/Customer/_files/customer_one_address.php
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.

NEW QUESTION # 38
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 a trusted signed certificate issued by a Certification Authority (CA) to secure each connection made by the payment solution protocol via https.
- B. Utilize the Advanced Encryption standard (aes-256) algorithm to encrypt all customer-sensitive data from the payment module.
- C. Utilize the payment provider iframe system to isolate content of the embedded frame from the parent web page.
Answer: C
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 # 39
The development of an Adobe Commerce website is complete. The website is ready to be rolled out on the production environment.
An Architect designed the system to run in a distributed architecture made up of multiple backend webservers that process requests behind a Load Balancer.
After deploying the system and accessing the website for the first time, users cannot access the Customer Dashboard after logging in. The website keeps redirecting users to the sign-in page even though the users have successfully logged in The Architect determines that the session is not being saved properly.
In the "app/etc/env.php", the session is configured as follows:
What should the Architect do to correct this issue?
- A. increase the session size with the command config:set system/security/max_session_size_admin
- B. Update the session host value to a shared Redis instance
- C. Utilize the Remote Storage module to synchronize sessions between the servers
Answer: B
Explanation:
Explanation
Option A is correct because updating the session host value to a shared Redis instance in the
"app/etc/env.php" file will allow the session to be saved properly and prevent users from being redirected to the sign-in page after logging in. Redis is a fast and reliable in-memory data store that can be used for session storage in Magento 2. By using a shared Redis instance, the session data can be accessed by any of the backend web servers behind the load balancer, regardless of which server handled the initial request. This ensures that the user's session is maintained and consistent across different servers1.
Option B is incorrect because increasing the session size with the command config:set system/security/max_session_size_admin will not solve the issue of session not being saved properly.
This command only affects the admin session size limit, not the customer session size limit. Moreover, this command does not address the root causeof the issue, which is that the session data is not shared among the backend web servers2.
Option C is incorrect because utilizing the Remote Storage module to synchronize sessions between the servers is not a viable solution for this issue. The Remote Storage module is a feature of Magento Commerce Cloud that allows storing media files and other static content on a remote storage service such as AWS S3 or Azure Blob Storage. This module does not support synchronizing sessions between servers, as sessions are dynamic and transient data that need to be stored in a fast and accessible data store such as Redis3.

NEW QUESTION # 40
An Adobe Commerce Architect is setting up a Development environment for an on-premises project that will be used for developers to specifically test functionality, not performance, before being passed to the Testing team.
The Magento application must run with the following requirements:
1. Errors should be logged and hidden from the user
2. Cache mode can only be changed from Command Line
3. Static files should be created dynamically and then cached
Which Application Mode is required to achieve this?
- A. Developer Mode
- B. Default Mode
- C. Production Mode
Answer: A
Explanation:
Explanation
Developer mode is the best option for setting up a development environment for testing functionality, not performance, before being passed to the testing team. In developer mode:
Errors are logged and hidden from the user. This ensures that the user does not see any uncaught exceptions or debugging information, but the developers can still access them from the log files.
Cache mode can only be changed from command line. This prevents any accidental or unauthorized changes to the cache settings from the admin panel or other sources.
Static files are created dynamically and then cached. This allows the developers to see the latest changes to the static files without having to run the static content deployment command every time. The static files are also cached for faster loading.

NEW QUESTION # 41
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 lower than the lowest declared plugin sortOrder and implement aroundGetData method.
- C. Declare a new plugin with the sortOrder value higher than the highest declared plugin sortOrder and implement afterGetData method.
Answer: C
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 # 42
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. Append the custom xml file name in "Magento\Config\Model\Config\Structure\Reader" in di.xml
- D. Make a Reader class that implements '\Magento\Framework\Config\Reader\Filesystem"
- E. Create a Data class that implements "\Magento\Framework\Config\Data"
Answer: D,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 # 43
A merchant is using a unified website that supports native Adobe Commerce B2B and B2C with a single store view.
The merchant's objective is to display the B2B account features, such as negotiable quotes and credit limits, in the header of the site on every page for logged-in users who belong to a B2B company account.
Each B2B company possesses its unique shared catalog and customer group, while numerous customer groups for non-B2B customers undergo changes. The merchant insists that this association should not be linked to customer groups.
Which two solutions should the Architect recommend for consideration, taking into account public data and caching? (Choose two.)
- A. Create a new HTTP Context variable to allow for separate public content to be cached for users in B2B companies where the output can be modified accordingly.
- B. Check if the current user is part of a B2B company within a block class and modify the output accordingly.
- C. Create a new custom condition for customer segments that allow for choosing whether a user is part of a B2B company and then use this segment to modify the output accordingly.
- D. Set whether the current user is part of a B2B company in the customer session and use that data directly to modify the output accordingly.
- E. Create a Virtual Type that switches the theme when a user is part of a B2B company so the output can be modified accordingly in the alternate theme.
Answer: A,C
Explanation:
Explanation
Option B is a valid solution because creating a new HTTP Context variable can allow for differentiating the public content cache for users who belong to a B2B company account. The HTTP Context variable can be used to modify the output of the header block accordingly, without affecting the performance or scalability of the site1 Option D is also a valid solution because creating a new custom condition for customer segments can enable targeting users who are part of a B2B company account. The customer segment can be used to modify the output of the header block accordingly, using layout updates or dynamic blocks. This solution can also leverage the existing customer segment functionality and avoid custom coding2 Option A is not a valid solution because switching the theme based on a virtual type can cause performance issues and increase the complexity of the site maintenance. Moreover, switching the theme can affect the entire site appearance, not just the header block3 Option C is not a valid solution because using the customer session data directly to modify the output of the header block can prevent the public content cache from working properly. The customer session data is private and cannot be cached, so this solution can negatively impact the performance and scalability of the site4 Option E is not a valid solution because checking if the current user is part of a B2B company within a block class can also prevent the public content cache from working properly. The block class logic is executed on every request, so this solution can negatively impact the performance and scalability of the site5 References:

NEW QUESTION # 44
An external system integrates functionality of a product catalog search using Adobe Commerce GraphQL API.
The Architect creates a new attribute my_attribute in the admin panel with frontend type select-Later, the Architect sees that Productlnterf ace already has the field my_attribute, but returns an Int value. The Architect wants this field to be a new type that contains both option id and label.
To meet this requirement, an Adobe Commerce Architect creates a new module and file etc/schema.graphqls that declares as follows:
After calling command setup:upgrade, the introspection of Productlnterface field my_attribute remains Int.
What prevented the value type of field my_attribute from changing?
- A. The interface Productlnterface is already declared in Magento.CatalogGraphQI module. Extending requires use of the keyword extend before a new declaration of Productlnterface.
- B. The fields of Productlnterface are checked during processing schema.graphqls files. If they have a corresponding attribute, then the backendjype of product attribute is set for field type.
- C. The Magento_CatalogGraphQI module occurs later in sequence than the Magento_GraphQI module and merging output of dynamic attributes schema reader overrides types declared in schema.graphqls
Answer: A
Explanation:
Explanation
According to the Adobe Commerce documentation, to extend an existing GraphQL interface, the keyword extend must be used before the interface name. This indicates that the new declaration is adding or modifying fields to the existing interface, rather than redefining it. If the keyword extend is omitted, the new declaration will be ignored and the original interface will be used. In this case, the Architect wants to change the type of the my_attribute field in the ProductInterface interface, which is already declared in the Magento.CatalogGraphQl module. Therefore, the Architect should use the keyword extend before declaring the ProductInterface interface in the schema.graphqlsfile of the custom module. This will allow the Architect to override the type of the my_attribute field from Int to MyAttributeType.

NEW QUESTION # 46
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. Magento framework uses INSERT on DUPLICATE, which leads to reaching the max limit of the increment of the column.
- B. EAV attribute import uses REPLACE, which leads to reaching the max limit of the increment of the column
- C. Integrity constraints were dropped after upgrading to the latest version, and the integrity checks were missed.
Answer: B
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 # 47
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. Modify project config.php file, configure 'admin_locales_for_deploy' value, and specify all required locales
- B. Adjust the tools build script and specify required locales during *setup:static-content:deploy' command
- C. Edit project env.php file, configure 'adminJocales_for_build' 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:

NEW QUESTION # 48
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. Clean the block_html cache along with full_page cache.
- C. Add the new \Magento\sales\Model\service\invoiceService Sinvoiceservice dependency at the end of the constructor signature.
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.
