QUESTION 19
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?

Change Session Cookie attribute to “SameSite=None”

Disable Session Validation for “HTTP_X_FORWARDED_FOR” header

Set Cookie Domain for both websites to “.example.com”

QUESTION 20
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?

Educate the merchant to not flush cache storage and only refresh the caches in future.

Set the ‘Stores > Configuration’ option for “Store Session Data Separately’ to ‘Yes’ in the Adobe Commerce Admin Panel.

Check app/etc/evn.php and make sure that the Redis configuration for caches and session data use different database numbers.

QUESTION 21
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?

Utilize the Remote Storage module to synchronize sessions between the servers

Update the session host value to a shared Redis instance

Increase the session size with the command config:set system/security/max_session_size_admin

QUESTION 22
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?

The attribute must have its apply_to field set to “staging” in the data patch file.

The attribute must also be added to
view/adminhtml/ul_component/catalogstaging_category_update_form.xml.

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.

QUESTION 23
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.)

Run bin/magento setup:upgrade –keep-generated to Upgrade database

Run bin/magento setup:upgrade -dry-run=true to upgrade database

Rim bin/magento setup:upgrade –convert-old-scripts=true to Upgrade database

Enable config flag under developer/zere _down_time/enabled

Enable config flag under deployment/blue_ green/enabled

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?

Edit project env.php file, configure ‘admin_locales_for.build’ value, and specify all required locales

Adjust the tool’s build script and specify required locales during ‘setup:static-content:deploy’ command

Modify project config.php file, configure ‘admin_locales_for_deploy’ value, and specify all required locales

QUESTION 25
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?

The developer forgot to use the getContentStagingValue() method to retrieve the active campaign value of the product data

The developer retrieved product data directly from the database using the entity_id column rather than a collection or repository.

The developer did not check for an active content staging campaign and emulates the campaign state when retrieving product data.

QUESTION 26
An Adobe Commerce Architect needs to scope a bespoke news section for a merchant’s Adobe Commerce storefront. The merchant’s SEO agency requests that the following URL structure:
news/{date}/{article_url_key}l where {date} is the publication date of the article, and {article_url_key} is the URL key of the article.
The Architect scopes that a news entity type will be created. The date and URL key data will be stored against each record and autogenerated on save. The values will be able to be manually overridden.
The Architect needs to manage routing this functionality and adhere to best practice.
Which two options should the Architect consider to meet these requirements? (Choose two.)

Create a standard controller route and an Index/Index index controller class that loads the relevant news article by matching the URL date and URL key parts.

Create an observer that listens to the controllers_front_send_response_before event, looks for the mm portion of the URL, and If it matches, loads the relevant news article by matching the URL date and URL key parts.

Create a plugin that intercepts lu^jentoXFraBeworkUppXActien::executed, looks for the news portion of the URL and if it matches, loads the relevant news article by matching the URL date and URL key parts.

Create a standard controller route and mapping the internal URLs (such as news/article/view/id/1) to rewrites that are generated on save and then stored in the URL rewrites table.

Create a custom router that runs before the standard router and matches the news portion of the URL.then looks for and loads a news article by matching the date and URL key parts of the URL.

QUESTION 27
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?

Implement _setCachedQuotes () and_getCachedQuotes() return the data if the request matches.

In _doShipmentRequest (), call canCollectRates() before sending request to the API

Override getResponse (), save the response to a variable, check if the response exists, then return.

QUESTION 28
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?

scope property should be added with a value of global

group property should be added with a value of 1

system property should be added with a value of true

QUESTION 29
An Adobe Commerce Architect is asked by a merchant using B2B features to help with a configuration issue.
The Architect creates a test Company Account and wants to create Approval Rules for orders. The Approval Rules tab does not appear in the Company section in the Customer Account Menu when the Architect logs in using the Company Administrator account.
Which two steps must be taken to fix this issue? (Choose two.)

Set ‘Enable Purchase Orders’ in the B2B Admin to TRUE

Merchant needs to log out of frontend and then log back in to load new permissions

Set Enable Purchase Orders’ on the Company Record to TRUE

Make sure that the ‘Purchase Order’ payment method is active

Set ‘Enable B2B Quote” in the B2B Admin to TRUE

QUESTION 30
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.)

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

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

Set the cache type to “Varnish Caching” in the Store Admin.
Stores > Configuration > Advanced > System > Full Page Cache > Caching Application

Use “Flush Cache Storage” instead of “Flush Magento Cache”

Set the cache destination host using magento CLIbin/magento setup:config:set
–http-cache-hosts<cache_server>:<varrnish port>

QUESTION 31
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.)

Use customer-data JS library to retrieve “my.attribute” value

Add a new context value of “my.attribute” to MagentoFrameworkAppHttpContext

Add a custom block and a phtml template with the content to the cmsjndexjndex.xml layout

Create a Customer Segment and use “my.attribute” in the conditions

Add a dynamic block with the content to the Home Page

QUESTION 32
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 deployment should have been done on Production to initialize Fastly caching.

The site URLs in the Production Database are the URLs of the Staging Instance and must be updated.

The Fastly credentials in the Production Database are incorrect.

QUESTION 33
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.

Data patch to register the new product type

New price model extending MagentoCatalogModelProductTypePrice

QUESTION 36
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?

Use VCL snippets to offload the redirect to Fastly.

Add each redirect in the .magento/routes.yaml file.

Add each redirect as a URL rewrite via the admin Ul.

QUESTION 37
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.)

Write a plugin for MagentoFrameworkConfigData::get() and read the custom xml files

Append the custom xml file name in “MagentoConfigModelConfigStructureReader” in di.xml

Create a Data class that implements “MagentoFrameworkConfigData’

Inject a “reader” dependency for “MagentoFrameworkConfigData” in di.xml

QUESTION 38
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?

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.

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.

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.

QUESTION 39
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.)

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.

Check if the current user is part of a B2B company within a block class and modify the output accordingly.

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.

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.

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.

QUESTION 40
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:

QUESTION 41
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.)

Invalidate the catalog_product_price indexer in the Adobe Commerce Admin Panel so that it is fully reindexed next time the cron runs.

Manually reindex the catalog_product_price index from the Command line:binmagentor indexer:reindex catalog_product_price.

Make sure that no custom or third-party modules modify the changelog and indexing process.

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.

Reduce the frequency of the cron job to 5 minutes so the items have more time to process.
