NEW QUESTION # 20
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. Hydrator for attributes belonging to the new product type
• B. Data patch to register the new product type
• C. New price model extending \Magento\Catalog\Model\Product\Type\Price
• D. Content of the etc/product_types.xml file
• E. Custom type model extended from the abstract Product Type model
• F. A new class with custom pricing logic, extending the abstract Product model class

Answer: C,D,E

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.

NEW QUESTION # 21
An Adobe Commerce Architect needs to log the result of a ServiceClass : : ge-Dara method execution after all plugins have executed. The method is public, and there are a few plugins declared for this method. Among those plugins are after and around types, and all have sortOrder specified.
Which solution should be used to meet this requirement?

• A. Declare a new plugin with the sortOrder value higher than the highest declared plugin sortOrder and implement aroundGetData method.
• B. Declare a new plugin with the sortOrder value higher than the highest declared plugin sortOrder and implement aroundGetData method
• C. Declare a new plugin with the sortOrder value higher than the highest declared plugin sortOrder and implement afterGetData method.
• D. Declare a new plugin with the sortOrder value lower than the lowest declared plugin sortOrder and implement aroundGetData method

Answer: B

Explanation:
https://devdocs.magento.com/guides/v2.3/extension-dev-guide/plugins.html
Explanation:
The sortOrder property from the plugin node declared in di.xml determines the plugin's prioritization when more than one plugin is observing the same method. The Magento\Framework\Interception\PluginListInterface which is implemented by Magento\Framework\Interception\PluginList\PluginList is responsible to define when to call the before, after, and around methods for each plugin.
Therefore, to log the result of a ServiceClass::getData method execution after all plugins have executed, the solution should be:

NEW QUESTION # 22
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 steps should the Architect take to fix the test errors?

• A.
• B.
• C.

Answer: A

Explanation:
The test errors are caused by using the wrong customer ID and address ID in the request. The correct customer ID and address ID should be obtained from the response of the previous request to create a customer and an address. The test code should use $this->customer->getId() and $this->address->getId() instead of hard-coded values. Reference: https://devdocs.magento.com/guides/v2.4/get-started/web-api-functional-testing.html

NEW QUESTION # 23
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. Create a Customer Segment and use "my.attribute" in the conditions
• B. Add a custom block and a phtml template with the content to the cmsjndexjndex.xml layout
• C. Use customer-data JS library to retrieve "my.attribute" value
• D. Add a new context value of "my.attribute" to Magento\Framework\App\Http\Context
• E. Add a dynamic block with the content to the Home Page

Answer: B,C

Explanation:
To display customer-specific content on the home page to Customers with "my.attribute" greater than 3, you need to use the following steps:
Use customer-data JS library to retrieve "my.attribute" value. The customer-data JS library allows you to access the customer data stored in the local storage of the browser. You can use the get() method to get the value of "my.attribute" for the current customer.
Add a new context value of "my.attribute" to Magento\Framework\App\Http\Context. The HTTP context is a mechanism that allows you to vary the cache of a page based on some parameters. By adding a new context value of "my.attribute", you can cache separate versions of the home page for customers with different values of "my.attribute".
Add a custom block and a phtml template with the content to the cms_index_index.xml layout. This step will create a block that will display the customer-specific content on the home page. You can use the phtml template to check the value of "my.attribute" and render the content accordingly.

NEW QUESTION # 24
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. Utilize the Remote Storage module to synchronize sessions between the servers
• B. Update the session host value to a shared Redis instance
• C. Increase the session size with the command config:set system/security/max_session_size_admin

Answer: B

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 # 25
A company has an Adobe Commerce store. An attribute named "my.attribute" (type "text") is created to save each product's global ID that is shared between multiple systems.
Several months after going live, the values of "my.attribute" are all integer. This causes a problem for the other systems when those systems receive this data.
An Adobe Commerce Architect needs to recommend a solution to change the type of "my.attribute" from textXo int Which two steps should the Architect take to achieve this? (Choose two.)

• A. Go to Admin > Stores > Attributes > Product, edit "my.attribute" and update type from "text' to "inf
• B. Migrate data from table "catalog_product_entity_text" to "catalog.producLentityjnt" for the attribute.id
• C. Run the Command bin/magentc indexer: reset catalog_product_attribute
• D. Create a Data Patch and update 'my.attribute' type from "text" to "inf
• E. Write a plugin for \Magento\Eav\Model\Entity\Attrlbute\Backend\AbstractBackend::afterLoad() and load data from "catalog_product_entity_int"

Answer: B,D

Explanation:
Option A is correct because it will migrate data from one table to another based on the attribute id, which is required when changing the attribute type14. Option D is correct because it will create a data patch that will update 'my.attribute' type from "text" to "int", which is a recommended way of changing the attribute type programmatically4.
To change the type of "my.attribute" from text to int, the Architect should take two steps: A) Migrate data from table "catalog_product_entity_text" to "catalog_product_entity_int" for the attribute_id. This step will move the existing values of the attribute from the text table to the int table, which corresponds to the new type. D) Create a Data Patch and update 'my.attribute' type from "text" to "int". This step will update the attribute metadata in the database and reflect the new type. Option B is incorrect because the Admin panel does not allow changing the type of an existing attribute. Option C is incorrect because writing a plugin for \Magento\Eav\Model\Entity\Attribute\Backend\AbstractBackend::afterLoad() will not change the type of the attribute, but only load data from a different table. Option E is incorrect because running the command bin/magento indexer:reset catalog_product_attribute will not change the type of the attribute, but only reset the indexer status. Reference: https://devdocs.magento.com/guides/v2.4/extension-dev-guide/attributes.html

NEW QUESTION # 26
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 # 27
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. Production Mode
• B. Developer Mode
• C. Default Mode

Answer: B

Explanation:
Explanation
Developer Mode is the mode best suited to achieve the requirements set out by the Adobe Commerce Architect. In Developer Mode, errors are logged and hidden from the user, and the cache mode can only be changed from the command line. Additionally, static files are created dynamically and then cached, which is the desired behavior for this project.

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 cache destination host using magento CLIbin/magento setup:config:set
  --http-cache-hosts<cache_server>:<varrnish port>
• C. 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
• D. Set the cache type to "Varnish Caching" in the Store Admin.
  Stores > Configuration > Advanced > System > Full Page Cache > Caching Application
• E. 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

Answer: C,E

NEW QUESTION # 29
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. Append the custom xml file name in "Magento\Config\Model\Config\Structure\Reader" in di.xml
• B. Make a Reader class that implements "\Magento\Framework\Config\Reader\Filesystem"
• C. Write a plugin for \Magento\Framework\Config\Data::get() and read the custom xml files
• D. Inject a "reader" dependency for "Magento\Framework\Config\Data" in di.xml
• E. Create a Data class that implements "\Magento\Framework\Config\Data'

Answer: B,E

Explanation:
Based on web searches, it seems that Magento uses different classes and interfaces to interact with configuration files, such as Data, Reader, and Converter12.
According to the documentation1, Data is a class that provides access to configuration data using a scope. Reader is an interface that reads configuration data from XML files. Converter is an interface that converts XML data into an array representation.
Based on these definitions, I would say that two possible steps that the Architect should make to meet the requirement are:
1. Create a Data class that implements "\Magento\Framework\Config\Data"
2. Make a Reader class that implements "\Magento\Framework\Config\Reader\Filesystem" These steps would allow the custom module to read all the XML configuration files declared in the system, merge them together, and use their values in PHP class.
The Architect should make two steps to meet this requirement: C) Create a Data class that implements "\Magento\Framework\Config\Data". This class will be responsible for reading and merging the custom xml configuration files and providing access to their values. The Data class should extend \Magento\Framework\Config\Data and use the constructor to inject the Reader class and the cache type. E) Make a Reader class that implements "\Magento\Framework\Config\Reader\Filesystem". This class will be responsible for loading and validating the custom xml configuration files from different modules. The Reader class should extend \Magento\Framework\Config\Reader\Filesystem and use the constructor to specify the file name, schema file, and validation state of the custom xml configuration files. Option A is incorrect because writing a plugin for \Magento\Framework\Config\Data::get() will not define a new xml configuration file, but rather modify the existing one. Option B is incorrect because appending the custom xml file name in "Magento\Config\Model\Config\Structure\Reader" in di.xml will not define a new xml configuration file, but rather add it to the system configuration structure. Option D is incorrect because injecting a "reader" dependency for "Magento\Framework\Config\Data" in di.xml will not define a new xml configuration file, but rather use an existing one.

NEW QUESTION # 30
An Adobe Commerce Architect needs to set up two websites on a single Adobe Commerce instance with base URLs: example.com and website2.example.com.
How should the Architect configure this project so that both websites can use the same customer base?

• A. Change Session Cookie attribute to "SameSite=None"
• B. Set Cookie Domain for both websites to ".example.com"
• C. Disable Session Validation for "HTTP_X_FORWARDED_FOR" header

Answer: B

Explanation:
Explanation
By setting the same cookie domain for both websites, the customer base can be shared between both websites, as the customer will be authenticated by the same cookie across both sites. This will ensure that customers don't have to log in twice when switching between the two sites.

NEW QUESTION # 31
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. A deployment should have been done on Production to initialize Fastly caching.
• B. The site URLs in the Production Database are the URLs of the Staging Instance and must be updated.
• C. The Fastly credentials in the Production Database are incorrect.

Answer: A

Explanation:
Explanation
The likely cause of the issue is that a deployment should have been done on Production to initialize Fastly caching. This is because when the database is migrated from Staging to Production, any changes made to the Staging Database will not be reflected in the Production environment until a deployment is made. This includes any changes made to the Varnish Cache, which needs to be cleared in order for the new products to appear on the frontend.

NEW QUESTION # 32
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/iuagento 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/evn.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
This is because when the Magento cache storage is flushed, all caches and session data stored in Redis are cleared. To prevent session data from being lost when caches are flushed, the merchant should configure different Redis databases for caches and session data, so that flushing the Magento cache storage only clears the caches and not the session data.

NEW QUESTION # 33
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 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 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 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: 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 # 34
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 061_.
* The id_prefix of frontend => default: is not set.
* The Architect has enabled and configured Redis L2 caching.
How should the preload.keys be configured?

• A.
• B.
• C.
• D.

Answer: C

NEW QUESTION # 35
A company wants to build an Adobe Commerce website to sell their products to customers in their country.
The taxes in their country are highly complex and require customization to Adobe Commerce. An Architect is trying to solve this problem by creating a custom tax calculator that will handle the calculation of taxes for all orders in Adobe Commerce.
How should the Architect add the taxes for all orders?

• A. Declare a new total collector in "etc/sales.xml" in a custom module
• B. Write a before plugin to \Magento\Quote\Model\QuoteManagement::placeOrder() and add the custom tax to the quote
• C. Add a new observer to the event 'sales_quote_collect_totals_before" and add the custom tax to the quote

Answer: A

Explanation:
you can create tax rules in Magento 2 by going to Stores > Taxes > Tax Rules and choosing or adding tax rates.
However, this may not be enough for complex tax scenarios that require customization.
https://amasty.com/knowledge-base/how-to-configure-tax-calculation-in-magento-2.html
To add a new total to the order, the Architect should declare a new total collector in the "etc/sales.xml" file of a custom module.
This file defines the order of calculation and rendering of totals.
The Architect should also implement a model class that extends \Magento\Quote\Model\Quote\Address\Total\AbstractTotal and overrides the collect() and fetch() methods to handle the logic of adding the custom tax to the quote and order.
Reference: https://devdocs.magento.com/guides/v2.4/howdoi/checkout/checkout_new_total.html

NEW QUESTION # 36
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 cart type. 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:
Option B is the correct way to declare the output of this mutation. The output type should be a union type that can return either a Cart or a ConfigurableProduct type, depending on the number of variants of the given product. The union type should be declared with the keyword union and the pipe symbol (|) to separate the possible types. Option A is incorrect because it uses the wrong syntax for declaring a union type. Option C is incorrect because it uses an interface type instead of a union type, which means that the output type should implement all the fields of the interface, which is not the case for Cart and ConfigurableProduct types. Reference: https://devdocs.magento.com/guides/v2.4/graphql/develop/create-graphqls-file.html
