NEW QUESTION # 13
An Architect is reviewing a custom module that is logging customer activity data on storefront using observers. The client reports that logs were recorded while the client was previewing storefront catalog pages from Admin Panel for a future scheduled campaign, using Adobe Commerce staging preview functionality.
What should the Architect check first to address this issue9

A. The plugin for the public method isAllowedObserver() from \Magento\Staging\Model\Event\Manager that alters the return value
B. The list of logging observers in bannedObservers parameter of \Magento\staging\Model\Event\Managertype in di.xml
C. The logging observers being copied from etc\events.xml to etc\adminhtml\events.xml with the attribute disabled=''true"

Answer: B

Explanation:
It will allow you to exclude logging observers from being executed during staging preview functionality by adding them to bannedObservers parameter of \Magento\staging\Model\Event\Manager type in di.xml file. This will prevent customer activity data from being logged while previewing storefront catalog pages from Admin Panel for a future scheduled campaign.
The Architect should check the list of logging observers in bannedObservers parameter of \Magento\Staging\Model\Event\Manager type in di.xml. This parameter defines the list of observers that should not be executed during staging preview. The Architect should add the logging observers to this list to prevent them from recording customer activity data while previewing the storefront catalog pages from Admin Panel.

NEW QUESTION # 14
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 /vi/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 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.
B. Use OAuth-based authentication to provide access to system resources. Integration will be registered by the merchant in the panel an OAuth handshake during activation. The third-party system should follow OAuth protocol to authorize.
C. 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.

Answer: B

Explanation:
To create an application that will integrate the Adobe Commerce system to get orders data for reporting using the get /v1/orders endpoint, you should use OAuth-based authentication to provide access to system resources. OAuth is a token-passing mechanism that allows a system to control which third-party applications have access to internal data without revealing or storing any user IDs or passwords. The integration will be registered by the merchant in the admin panel and will perform an OAuth handshake during activation. The third-party system should follow OAuth protocol to authorize. The merchant will have the ability to restrict or extend access to resources as well as to revoke the access using Admin Panel. Reference: 1

NEW QUESTION # 15
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 marketplacejeeds.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. Implement validation rules in the Converter class for the Config Reader
B. Create validation rules in marketplace.schema.xsd.
C. Add the Uniform Resource Name to the XSD file in the config XML file.
D. Provide schema to validate an individual file.
E. Create a class that implements \Magento\Framework\Config\Datalnterface.
F. Provide schema to validate a merged file.

Answer: C,D,F

Explanation:
To ensure validation of the configuration files with unique validation rules for the individual and merged files, you need to do the following steps:
Add the Uniform Resource Name (URN) to the XSD file in the config XML file. The URN is a unique identifier for a resource that follows a specific syntax. For example:
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Vendor_Module:etc/marketplacefeeds.xsd"> Provide schema to validate a merged file. The schema defines the structure and constraints of the XML document that represents the merged configuration from all modules. The schema file should be named as <config_file_name>.xsd and placed in the etc directory of the module. For example:
marketplacefeeds.xsd
Provide schema to validate an individual file. The schema defines the structure and constraints of the XML document that represents the configuration from a single module. The schema file should be named as <config_file_name>_merged.xsd and placed in the etc directory of the module. For example:
marketplacefeeds_merged.xsd

NEW QUESTION # 16
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. Set CONSUMER_WAIT_FOR_MAX_MESSAGES variable true in deployment stage.
B. Change max_messages from 10,000 to 1,000 for CRON_CONSUMER_RUNNERvariable.
C. Increase multiple_process limit to spawn more processes for each consumer.

Answer: A

Explanation:
Explanation
The best way to meet this requirement is to set the CONSUMERWAITFORMAXMESSAGES variable to true in the deployment stage. This variable will ensure that the consumer will not terminate when there are no more messages in the queue and will instead wait until a new message is available, preventing it from closing the connection prematurely. Additionally, the multiple_processes limit can be increased to spawn more processes for each consumer, which will help ensure that messages can be processed faster.

NEW QUESTION # 17
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\\T\\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 MagentoGraphQICacheModelCacheableQuery and call setCacheValidity (true) on it as part of the resolver's rescive function
C. Specify a @cache (cacheable: false directive for each GraphQL query, making sure that the data returned is not cached, and is up to date

Answer: A

Explanation:
This option would allow caching GraphQL query results using Varnish or Fastly with proper invalidation and differentiation mechanisms.
To solve the problem of out-of-date information in GraphQL queries, the Architect should specify a @cache (cacheIdentity: path\T\identityClass) directive for each GraphQL query, corresponding to a class that adds cache tags for relevant brands and associated products. This will allow Varnish to invalidate the cache for these queries when the brand or product data changes. Option A is incorrect because it will make the queries cacheable without any cache tags, which will not solve the problem. Option B is incorrect because it will disable caching for these queries entirely, which will degrade performance. Reference: https://devdocs.magento.com/guides/v2.4/graphql/caching.html

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. Run bin/magento setup:upgrade --keep-generated to Upgrade database
B. Run bin/magento setup:upgrade -dry-run=true to upgrade database
C. Enable config flag under developer/zere _down_time/enabled
D. Enable config flag under deployment/blue_ green/enabled
E. Rim bin/magento setup:upgrade --convert-old-scripts=true to Upgrade database

Answer: B,D

Explanation:
1. Running bin/magento setup:upgrade -dry-run=true allows you to check the upgrade scripts without applying any changes to the database. This can help you identify any potential issues before the actual upgrade. E. Enabling config flag under deployment/blue_ green/enabled allows you to use the blue-green deployment strategy, which creates a copy of the production environment and switches traffic between the two environments after testing the new version. This can help you achieve zero downtime during the deployment process. Reference: https://devdocs.magento.com/guides/v2.4/comp-mgr/cli/cli-upgrade.html#upgrade-cli-dryrun https://devdocs.magento.com/cloud/live/stage-prod-migrate-prereq.html#blue-green-deployment

NEW QUESTION # 19
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_form.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 also be added to view/adminhtml/ul_component/catalogstaging_category_update_form.xml.
B. The attribute must have its apply_to field set to "staging" in the data patch file.
C. The attribute must have<item name=''allow_staging'' xsi:type="boolean''>true<item> set in the =category_form.xml file under the attributes config" section.

Answer: A

Explanation:
This is because, in order to change the attribute when scheduling new category updates, the attribute must be added to the view/adminhtml/ulcomponent/catalogstagingcategoryupdateform.xml file in order to be displayed in the additional form when scheduling updates. This additional form is used to set the values for the category attributes when scheduling updates.

NEW QUESTION # 20
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 napp/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. Utilize the Remote Storage module to synchronize sessions between the servers
C. Update the session host value to a shared Redis instance

Answer: C

Explanation:
When using multiple backend servers behind a load balancer, the session data must be stored in a shared location that is accessible by all servers. Otherwise, the session data will be inconsistent and users may experience issues such as being logged out unexpectedly. Redis is a recommended option for storing session data in a distributed architecture, as it provides fast and reliable access to the data. The session host value in the env.php file must point to the Redis instance that is used for session storage. Reference: https://devdocs.magento.com/guides/v2.4/config-guide/redis/redis-session.html

NEW QUESTION # 21
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 Productinterface already has the field my_atcribute, but returns an mc 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 xy_attribute remains int. What prevented the value type of field my_attribute from changing?

A. 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
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 interface Productlnterface is already declared in Magento.CatalogGraphQI module. Extending requires use of the keyword -xceni before a new declaration of Productlnterface.

Answer: A

Explanation:
products query is a GraphQL query that returns information about products that match specified search criteria. It also shows how to use ProductInterface fields to retrieve product data.
https://devdocs.magento.com/guides/v2.3/graphql/queries/products.html
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. The dynamic attributes schema reader is responsible for adding product attributes to the Productinterface based on the backend type of the attribute. Since the attribute my_attribute has a backend type of int, the field my_attribute in the Productinterface will also have a type of int, regardless of the custom type declared in the schema.graphqls file. To avoid this, the Architect should either change the backend type of the attribute to match the custom type, or use a different name for the field that does not conflict with the attribute name. Reference: https://devdocs.magento.com/guides/v2.4/graphql/develop/create-graphqls-file.html

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 is implemented 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. In _doShipmentRequest (), call canCollectRates() before sending request to the API
B. Implement _setCachedQuotes () and_getCachedQuotes() return the data if the request matches.
C. Override getResponse (), save the response to a variable, check if the response exists, then return.

Answer: B

Explanation:
Implementing setCachedQuotes () andgetCachedQuotes() in the carrier model can allow the store to store the cart data in a cache, so that repeated requests with the same content can be retrieved from the cache instead of sending a new request to the API. This can reduce the number of requests and avoid hitting the quota limit.

NEW QUESTION # 23
An Architect working on a headless Adobe Commerce project creates a new customer attribute named my_attribure. 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)

B)

C)

A. Option B
B. Option C
C. Option A

Answer: A

Explanation:
Option B is the correct way to make sure the vcl_hash function of Varnish also considers the newly created attribute. The Architect should create a new module that depends on Magento_Fastly and declare a plugin for \Magento\Fastly\Model\Config::getVclSnippets() method. The plugin should add a new snippet to the result array with the type 'recv' and the content 'set req.http.my_attribute = req.http.X-Magento-Vary;'. This will append the value of the customer attribute to the hash key used by Varnish for caching. Option A is incorrect because it modifies the core file of Magento_Fastly module, which is not recommended and can cause issues during upgrades. Option C is incorrect because it uses the wrong type and content for the snippet, which will not affect the vcl_hash function. Reference: https://devdocs.magento.com/cloud/cdn/fastly-vcl-bypass-to-origin.html According to the Adobe Commerce Developer Guide2, to make sure the vcl_hash function of Varnish also considers the newly created attribute, the Architect should use a plugin for Magento\Customer\Model\Context::getVaryString method and add the attribute value to the vary string. This will ensure that Varnish caches different versions of GraphQL queries based on the attribute value of the customer. Therefore, option B is correct. Option A is not correct because it does not affect the vcl_hash function. Option C is not correct because it does not use a plugin for the getVaryString method.

NEW QUESTION # 24
An Adobe Commerce Architect is troubleshooting an issue on an Adobe Commerce Cloud project that is not yet live.
The developers migrate 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 frontend.
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. The Fastly credentials 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 Fastly caching.

Answer: A

Explanation:
The Fastly credentials in the Production Database are incorrect. This means that the Varnish cache cannot be cleared by Commerce when new products are imported. The Fastly credentials should be updated to match the Production environment. See Configure Fastly credentials in the Adobe Commerce Help Center. Reference: https://experienceleague.adobe.com/docs/commerce-operations/configuration-guide/cache/use-varnish-cache.html?lang=en1 https://support.magento.com/hc/en-us/articles/360006008192-Configure-Fastly-credentials

NEW QUESTION # 25
An Architect agrees to improve company coding standards and discourage using Helper classes in the code by introducing a new check with PHPCS.
The Architect creates the following:
* A new composer package under the AwesomeAgency\CodingStandard\ namespace
* The ruleset. xml file extending the Magento 2 Coding Standard
What should the Architect do to implement the new code rule?

Answer: B

Explanation:
Option B is the correct way to implement the new code rule. The Architect should create a new class that extends the \PHP_CodeSniffer\Sniffs\Sniff abstract class and implements the register() and process() methods. The register() method should return an array of tokens that the rule applies to, such as T_CLASS. The process() method should check if the class name contains Helper and add a warning or an error if it does. The Architect should also reference the new class in the ruleset.xml file using the <rule ref> tag. Reference: https://devdocs.magento.com/guides/v2.4/coding-standards/technical-guidelines.html#14-code-style https://github.com/squizlabs/PHP_CodeSniffer/wiki/Coding-Standard-Tutorial

NEW QUESTION # 26
A merchant is using a unified website that supports native Adobe Commerce B2B and B2C with a single store view.
The merchant wants to show the B2B account features like negotiable quotes and credit limits in the header of the site on every page for the logged-in users who are part of a B2B company account.
Each B2B company has its own individual shared catalog and customer group, and many customer groups for non B2B customers change. The merchant requests that this should not be tied to customer groups.
Which two solutions should the Architect recommend considering 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. 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.
C. Check if the current user is part of a B2B company within a block class and modify the output accordingly.
D. Create a plugin that switches the theme when a user is part of a B2B company so the output can be modified accordingly in the alternate theme.
E. 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.

Answer: A,B

Explanation:
C would involve creating a new custom condition for customer segments that allow for choosing if a user is part of a B2B company, and then use this segment to modify the output accordingly. E would involve creating 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.
To show the B2B account features in the header of the site on every page for the logged-in users who are part of a B2B company account, the Architect should recommend two solutions: 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. This solution will allow the merchant to create a customer segment based on the custom condition and use it to display different content in the header for B2B users. E) 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. This solution will ensure that the public content cache is varied based on the custom HTTP Context variable, which can be set based on whether the user is part of a B2B company or not. Option A is incorrect because switching the theme based on the user's B2B status is not a scalable or maintainable solution, and it will also affect the entire site's appearance, not just the header. Option B is incorrect because checking the user's B2B status within a block class will not work with public content cache, as it will not vary the cache based on that condition. Option D is incorrect because setting the user's B2B status in the customer session will not work with public content cache, as it will not vary the cache based on that data. Reference: https://devdocs.magento.com/guides/v2.4/extension-dev-guide/segmentation.html https://devdocs.magento.com/guides/v2.4/extension-dev-guide/cache/page-caching/public-content.html

NEW QUESTION # 27
An Adobe Commerce store owner sets up a custom customer attribute "my.attribute" (type int).
An Architect needs to display customer-specific content on the home page to Customers with "my.attribute" greater than 3. The website is running Full Page Cache.
Using best practices, which two steps should the Architect take to implement these requirements? (Choose two.)

A. Add a custom block and a phtml template with the content to the cmsjndexjndex.xml layout
B. Create a Customer Segment and use "my.attribute" in the conditions
C. Add a dynamic block with the content to the Home Page
D. Add a new context value of "my.attribute" to Magento\Framework\App\Http\Context
E. Use customer-data JS library to retrieve "my.attribute" value

Answer: A,E

Explanation:
Explanation
https://docs.magento.com/user-guide/v2.3/stores/attributes-customer.html displaying custom customer attributes on cached pages using best practices involves several steps, such as:
* Creating a custom block and a phtml template with the content to display
* Adding the custom block to the layout file of the page where it should appear
* Creating a section.xml file to declare a new section for the custom attribute
* Creating a plugin for Magento\Customer\CustomerData\SectionPoolInterface to add the custom attribute value to the section data
* Using customer-data JS library to retrieve and display the custom attribute value in the phtml template

NEW QUESTION # 28
An Adobe Commerce system is configured to run in a multi-tier architecture that includes:
* A cache server with Varnish installed
* A backend web server with Adobe Commerce installed
* A database server with MySQL installed
When an Adobe Commerce Architect tries to clean the cache from the Store Admin by using the "Flush Magento Cache" in Cache Management, the Full Page Cache does not clear.
Which two steps should the Architect take to make the Full Page Cache work properly? (Choose two.)

A. Use "Flush Cache Storage" instead of "Flush Magento Cache"
B. Set the backend port destination to the frontend server's Varnish port in the Store Admin Stores > Configuration > Advanced > System > Full Page Cache > Varnish Configuration > Backend Port
C. Set the backend destination host to the frontend server's address in the Store Admin Stores > Configuration > Advanced > System > Full Page Cache > Varnish Configuration > Backend Host
D. Set the cache destination host using magento CLI bin/magento setup:config:set --http-cache-hosts<cache_server>:<varrnish port>
E. Set the cache type to "Varnish Caching" in the Store Admin.
Stores > Configuration > Advanced > System > Full Page Cache > Caching Application

Answer: D,E

Explanation:
To use Varnish as the full page cache, the cache type must be set to "Varnish Caching" in the Store Admin. This will enable the "Flush Magento Cache" button to send a purge request to Varnish. Additionally, the cache destination host must be specified using the magento CLI command to tell Magento which Varnish servers to purge.

NEW QUESTION # 29
While reviewing a newly developed pull request that refactors multiple custom payment methods, the Architect notices multiple classes that depend on \Magento\Framework\Encryption\EncryptorInterf ace to decrypt credentials for sensitive dat a. The code that is commonly repeated is as follows:

In each module, the user_secret config is declared 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. Create a common config service class vendor\Payment\Gateway\config\Config under Vendor.Payment and use it as a parent class for all of the Vender \EaymentModule\Gateway\Config\Config Classes and remove $sccpeConfig and $encryptor dependencies
B. Add a plugin after the getvalue method of $sccpeConfig, remove the $encryptor from dependency and use it in the plugin to decrypt the value if the config name is 'user.secret?
C. Replace all Vendor\PaymentModule\Gateway\Config\Config Classes With virtualTyp- Of Magento\Payxer.t\Gateway\Conflg\Config and Set <user_secret backend_Model="Magento\Config\Model\Config\Backend\Encrypted" /> under ccnfig.xml

Answer: C

Explanation:
To avoid redundant dependency and duplicate code among the methods, 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 allow using the core config class that already has the scopeConfig dependency and the logic to get the value from the config. The backend_model attribute will ensure that the user_secret value is encrypted and decrypted automatically by the core EncryptorInterface class. Option B is incorrect because it will add unnecessary complexity and overhead to the scopeConfig object. Option C is incorrect because it will still require creating a custom config service class and injecting the encryptor dependency. Reference: https://devdocs.magento.com/guides/v2.4/payments-integrations/base-integration/integration-intro.html https://devdocs.magento.com/guides/v2.4/config-guide/prod/config-reference-encryptor.html

NEW QUESTION # 30
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 Kyservice.
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 less than 13
B. Introduce a new class accepting those five scalars and use it in the constructor and the remaining logic of Myservice
C. Modify the code of Myservice so the number of different classes, interfaces, and scalar types used as parameters in the constructor and other methods is less than 13

Answer: B

Explanation:
The best way to fix the code so that it complies with the coding standard rule is to introduce a new class accepting those five scalars and use it in the constructor and the remaining logic of Myservice. This will reduce the number of different classes, interfaces, and scalar types used as parameters in the constructor and other methods to less than 13, which is the limit set by the coding standard. Additionally, any extra code that is not necessary can be removed to reduce the general complexity of the class and improve readability.
The coding standard rule that is violated by the code is the Coupling Between Objects (CBO) metric. This metric measures the number of different classes and interfaces that a class depends on. A high CBO value indicates that the class is tightly coupled with other classes and interfaces, which makes it harder to maintain and test. The recommended CBO value for Adobe Commerce classes is less than 13. To reduce the CBO value of Myservice, 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 depend on one additional class instead of five scalars, and the CBO value will be reduced by four. Reference: https://devdocs.magento.com/guides/v2.4/coding-standards/code-standard-php.html#coupling-between-objects

NEW QUESTION # 31
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. Edit project env.php file, configure 'admin_locales_for.build' value, and specify all required locales
C. Adjust the tool's build script and specify required locales during 'setup:static-content:deploy' command

Answer: C

Explanation:
The 'setup:static-content:deploy' command allows you to generate static view files for specific locales. If you do not specify any locales, the command uses the default locale that is set in the configuration. To avoid breaking the site when changing interface locale in the Admin Panel, you need to generate static view files for all the locales that you want to use. You can do this by adjusting the tool's build script and adding the locales as arguments to the 'setup:static-content:deploy' command. For example:
bin/magento setup:static-content:deploy en_US fr_FR de_DE
This will generate static view files for English, French, and German locales. Reference: https://experienceleague.adobe.com/docs/commerce-operations/configuration-guide/setup/static-view.html?lang=en#generate-static-view-files

NEW QUESTION # 32
A merchant notices that product price changes do not update on the storefront.
The index management page in the Adobe Commerce Admin Panel shows the following:
* All indexes are set to 'update by schedule'
* Their status is 'ready'
* There are no items in the backlog
* The indexes were last updated 1 minute ago
A developer verifies that updating and saving product prices adds the relevant product IDs into the catalog_product_price_cl changelog table.
Which two steps should the Architect recommend to the developer to resolve this issue? (Choose two.)

A. Manually reindex the catalog_product_price index from the Command line:bin\magentor indexer:reindex catalog_product_price.
B. Invalidate the catalog_product_price indexer in the Adobe Commerce Admin Panel so that it is fully reindexed next time the cron runs.
C. Make sure that the version_id for the price indexer in the mview_state table is not higher than the last entry for the same column in the changelog table and re-synchronize.
D. Reduce the frequency of the cron job to 5 minutes so the items have more time to process.
E. Make sure that no custom or third-party modules modify the changelog and indexing process.

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

Answer: A

Explanation:
The best way to meet this requirement is to set the CONSUMERWAITFORMAXMESSAGES variable to true in the deployment stage. This variable will ensure that the consumer will not terminate when there are no more messages in the queue and will instead wait until a new message is available, preventing it from closing the connection prematurely. Additionally, the multiple_processes limit can be increased to spawn more processes for each consumer, which will help ensure that messages can be processed faster.
Setting CONSUMER_WAIT_FOR_MAX_MESSAGES variable true in deployment stage will make sure that consumers do not terminate after processing available messages in the queue when CRON job is running these consumers. This will prevent consumers from closing TCP connections too often and improve performance. See Start message queue consumers in the Adobe Commerce Help Center1.

NEW QUESTION # 34
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: A

Explanation:
Explanation
According to the Adobe Commerce documentation, when retrieving product data, developers must use the getContentStagingValue() method to ensure that the active campaign value for theproduct is retrieved. This method takes into account any content staging campaigns that might be active, and returns the appropriate value from the content staging campaign rather than the default value from the database. Failing to use this method can result in incorrect data being returned in the product feed.

NEW QUESTION # 35
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 developments are valid when reviewing the implementation? (Choose three.)

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

Answer: A,B,C

Explanation:
Explanation
According to some tutorials45, creating a custom product type in Adobe Commerce involves several steps, such as:
* Creating a product_types.xml file in etc folder to declare the new product type
* Creating a custom type model that extends from an abstract product type model
* Creating a custom price model that extends from an abstract price model
* Creating a layout file for the new product type
* Creating a data patch to register the new product type
Based on these steps, I would say that three possible developments that are valid when reviewing the implementation are:
* A. Content of the etc/product_types.xml file
* C. Custom type model extended from the abstract Product Type model
* F. New price model extending \Magento\Catalog\Model\Product\Type\Price These developments would allow creating a new product type with its own custom pricing logic and attributes.
