NEW QUESTION # 18
An Adobe Commerce Architect needs to ensure zero downtime during the deployment process of Adobe Commerce on-premises. Which two steps should the Architect follow? (Choose two.)
- A. Enable Config flag Under developer/zero_down_time/enabled
- B. Run bin/magento setup:upgrade - -keep-generated to Upgrade database
- C. Run bin/magento setup:upgrad --convert-old-scripts-true to Upgrade database
- D. Enable Config flag Under deployement/blue_green/enabled
- E. Run bin/magento setup:upgrade --dry-run=true to upgrade database
Answer: B,D
Explanation:
Explanation
Option A is correct because enabling the config flag under deployment/blue_green/enabled is one of the steps to ensure zero downtime during the deployment process of Magento 2 on-premises. This flag enables the blue-green deployment feature, which allows deploying a new version of the Magento application to a separate environment (blue) without affecting the current live environment (green). Once the new version is ready, the traffic can be switched from green to blue with minimal or no downtime1.
Option C is correct because running bin/magento setup:upgrade --keep-generated is another step to ensure zero downtime during the deployment process of Magento 2 on-premises. This command updates the database schema and data without deleting the generated code and static view files. This way, the Magento application can still serve requests from the cache while the database is being upgraded2.
Option B is incorrect because running bin/magento setup:upgrade --dry-run=true does not upgrade the database, but only checks if there are any errors or conflicts in the database schema or data. This command can be used for testing purposes, but it does not affect the deployment process or the downtime3.
Option D is incorrect because there is no such option as --convert-old-scripts-true for the bin/magento setup:upgrade command. This option does not exist in Magento 2 and does not have any effect on the deployment process or the downtime.
Option E is incorrect because there is no such config flag as developer/zero_down_time/enabled in Magento 2. This flag does not exist in Magento 2 and does not have any effect on the deployment process or the downtime.

NEW QUESTION # 19
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. Default Mode
- B. Production Mode
- C. Developer Mode
Answer: C
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 # 20
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. Set cohsumers_wait_for_max_MESSAGES variable true in deployment stage.
- C. Change max_messages from 10,000 to 1,000 for CRON_CONSUMERS_RUNNER variable.
Answer: B
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 # 21
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 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.
- B. 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.
- C. 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.
Answer: C
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 # 22
An Architect needs to integrate an Adobe Commerce store with a new Shipping Carrier. Cart data is sent to the Shipping Carrier's API to retrieve the price and display to the customer. After the feature isimplemented on the store, the API hits its quota and returns the error "Too many requests". The Shipping Carrier warns the store about sending too many requests with the same content to the API.
In the carrier model, what should the Architect change to fix the problem?
- A. Implement _setCachedQuotes() and _getCachedQuotes(), return the data if the request matches.
- B. Override getResponse, save the response to a variable, check if the response exists, then return.
- C. ln_doShipmentRequest()f call canCollectRates() before sending request to the API.
Answer: A
Explanation:
Explanation
The carrier model class can implement caching methods to store and retrieve the quotes from the API based on the request parameters. This can reduce the number of API calls and improve the performance of the shipping rate calculation. The _setCachedQuotes() method can save the response from the API to a cache storage, and the _getCachedQuotes() method can check if there is a cached response for the current request and return it if it exists. References: Caching in carrier model, Carrier model interface
NEW QUESTION # 23
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 in the magento/routes.yaml file.
- B. Add each redirect as a URL rewrite via the admin Ul.
- 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 # 24
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. Modify project config.php file, configure 'admin_locales_for_deploy' value, and specify all required locales
- C. Adjust the tools build script and specify required locales during *setup:static-content:deploy' command
Answer: C
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 # 25
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. group property should be added with a value of 1
- B. scope property should be added with a value of global
- C. system property should be added with a value of true
Answer: A
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 # 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. 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. 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
- 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.

- A. A new class with custom pricing logic, extending the abstract Product model class
- B. Hydrator for attributes belonging to the new product type
- C. Custom type model extended from the abstract Product Type model
- D. Content of the etc/product_types.xml file
- E. New price model extending \Magento\Catalog\Model\Product\Type\Price
- F. Data patch to register the new product type
Answer: C,D,E
NEW QUESTION # 28
An Adobe Commerce Architect designs and implements functionality that introduces a new Complex Product Type to the existing Adobe Commerce website. Besides visual demonstration of the new product type, the changes include adjustments to the price index.
The website utilizes a multi-dimensional indexer feature to store the price index. The Architect decides to cover it with integration tests. After creating and running one test, the Architect discovers that database storage is not being fully cleaned.
The test method has the following annotation declaration:
Which adjustment should the Architect make to fix this issue?
- A. Create Customer_ProductType: :Test/_files/{fixture_name)_rollback.php for every fixture
- B. Add annotation @magentoApplsolation enabled to method PHPDoc
- C. Modify method PHPDoc and change annotation @magentoDbIsolation to enabled
Answer: C
Explanation:
Explanation
The issue here is that the database storage is not being fully cleaned after the test is run. The solution is to modify the method PHPDoc and change the annotation @magentoDbIsolation to enabled. This will ensure that the database storage is fully cleaned after the test is run. References:

NEW QUESTION # 29
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. GraphQL requests are always run against the default store view unless a store header or store cookie is provided.
- C. The magento-vars.php file is not processed for any GraphQL requests, so the default website is always processed.
Answer: B
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 # 30
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. Update the session host value to a shared Redis instance
- B. Utilize the Remote Storage module to synchronize sessions between the servers
- C. increase the session size with the command config:set system/security/max_session_size_admin
Answer: A
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 # 32
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. 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.
- C. Specify a @cacgecacheable(cacheable: false) directive for each GraphQL query, making sure that the data returned is not cached, and is up to date
Answer: 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.

The developer uses the following command: bin/magento module:uninstall Vendor_SampleMinimal Vendor_SampleModifyContent When the command is run from CLI, the developer fails to remove the database schema and data defined in the module Uninstall class. Which three requirements should the Architect recommend be checked to troubleshoot this issue? (Choose three.)
- A. --remove-data option is specified as an argument for the CLI command
- B. --remove-schema and --remove-data options are specified as arguments for the CLI command
- C. bin/magento maintenance:enable command should be run in CLI before
- D. invoked uninstall() and uninstallschema are defined in the Uninstall class
- E. composer.json file is present and defines the module as a composer package
- F. invoked unlnstalK) method is implemented in the Uninstall class

NEW QUESTION # 34
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. Clean the block_html cache along with full_page cache.
- B. Add the new \Magento\sales\Model\service\invoiceService Sinvoiceservice dependency at the end of the constructor signature.
- 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 # 35
An Architect working on a headless Adobe Commerce project creates a new customer attribute named my_attribute. Based on the attribute value of the customer, the results of GraphQI queries are modified using a plugin. The frontend application is communicating with Adobe Commerce through Varnish by Fastly. which is already caching the queries that will be modified. The Adobe Commerce Fastly extension is installed, and no other modifications are made to the application.
Which steps should the Architect take to make sure the vcl_hash function of Varnish also considers the newly created attribute?
- A. Createa new class inheriting from Magento\Framework\GraphQi\Query\Resolver\identityinterfaca and returning the value of my_attributefrom the getidentities function.
Then specify a ecache(cacheidentity: Path\\To\\identityclass) directive for each GraphQL query to include the newly created IdentityClass to each query that adds the cache tags for each customer. - B. Create a new ClaSS inheriting from
Magento\GraphQlCache\Model\CacheId\CacheIdFactorProvidftrInterface and returning the Value of my_attribute from the getFactorValuefunction and my_attribute from the getFactorName function. Then add this class through Dl to the idFactorProviders array ofMagento\GraphQlCache\Model\CacheId\CacheIdCalculator. - C. Create a new class inheriting from Magento\customer\customerData\stctionSourceinterface and returning the value of my_attributefrom the getSectionData function. Then add thisClaSS through the sectionSourceMap array Of Magento\Customer\CustomerData\SectionPoolInterface.
Answer: B
Explanation:
Explanation
To make sure the vcl_hash function of Varnish considers the newly created attribute, the Architect needs to do the following steps:
Create a new class that implements the
Magento\GraphQlCache\Model\CacheId\CacheIdFactorProviderInterface interface. This interface defines two methods: getFactorName and getFactorValue. The getFactorName method should return the name of the attribute, in this case, my_attribute. The getFactorValue method should return the value of the attribute for the current customer, which can be obtained from the customer session or customer repository1.
Add this class to the idFactorProviders array of
Magento\GraphQlCache\Model\CacheId\CacheIdCalculator through dependency injection. The CacheIdCalculator is responsible for generating a cache ID for each GraphQL request based on the factors provided by the idFactorProviders. By adding the new class to this array, the Architect ensures that the cache ID will include the value of my_attribute1.
The cache ID is then used by Varnish to hash and lookup the cached response for each request. By including my_attribute in the cache ID, the Architect ensures that Varnish will serve different responses based on the attribute value of the customer2.

NEW QUESTION # 36
An Architect is investigating a merchant's Adobe Commerce production environment where all customer session data is randomly being lost. Customer session data has been configured to be persisted using Redis, as are all caches (except full page cache, which is handled via Varnish).
After an initial review, the Architect is able to replicate the loss of customer session data by flushing the Magento cache storage, either via the Adobe Commerce Admin Panel or running bin/magento cache: flush on the command line. Refreshing all the caches in the Adobe Commerce Admin Panel or running bin/magento cache: clean on the command line does not cause session data to be lost.
What should be the next step?
- A. Educate the merchant to not flush cache storage and only refresh the caches in future.
- B. Check app/etc/env.php and make sure that the Redis configuration for caches and session data use different database numbers.
- C. Set the Stores > Configuration' option for Store Session Data Separately' to 'Yes' in the Adobe Commerce Admin Panel.
Answer: B
Explanation:
Explanation
The issue here is that the customer session data is randomly being lost when flushing the Magento cache storage. This is because the Redis configuration for caches and session data might be using the same database number, which causes the session data to be deleted along with the caches. The solution is to check the app/etc/env.php file and make sure that the Redis configuration for caches and session data use different database numbers. This will prevent the session data from being affected by the cache operations. References:

NEW QUESTION # 37
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 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.
- B. 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
- C. The interface Productlnterface is already declared in Magento.CatalogGraphQI module. Extending requires use of the keyword extend before a new declaration of Productlnterface.
Answer: C
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.
