Question 1

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.)

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

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

CMake 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.

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

EManually reindex the catalog_product_price index from the command line: bin/magento indexer:reindex catalog_product_price.

Answer : B, C

The issue here is that the product price changes are not reflected on the storefront, even though the indexes are set to update by schedule and there are no items in the backlog. This indicates that there might be some problem with the changelog and indexing process, which are responsible for tracking and applying the data changes to the index tables. Therefore, the Architect should recommend the developer to check if any custom or third-party modules interfere with the changelog and indexing process, and disable or fix them if needed. Additionally, the Architect should recommend the developer to verify that the version_id for the price indexer in the mview_state table is consistent with the last entry for the same column in the changelog table, and re-synchronize them if they are out of sync.This will ensure that the indexer can process all the data changes correctly and update the index tables accordingly.Reference: https://experienceleague.adobe.com/docs/commerce-admin/systems/tools/index-management.html?lang=en#cron-groups-and-processes1https://devdocs.magento.com/guides/v2.4/extension-dev-guide/indexing.html#m2devgde-mview2

Question 2

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.

Following best practices, how should the Architect add the taxes for all orders?

AAdd a new observer to the event sales.quote.collecLtotals.before'' and add the custom tax to the quote

BWrite a before plugin to \Magento\Quote\Model\QuoteManagement::placeOrder() and add the custom tax to the quote

CDeclare a new total collector in 'etc/sales.xmr in a custom module

Answer : C

According to the Adobe Commerce documentation, the best way to add a custom tax calculation to all orders is to declare a new total collector in the ''etc/sales.xml'' file of a custom module. This way, the custom tax logic can be implemented in a separate class that extends the \Magento\Quote\Model\Quote\Address\Total\AbstractTotal class and overrides the collect() and fetch() methods. The collect() method is responsible for calculating the tax amount and adding it to the quote address, while the fetch() method is responsible for displaying the tax amount in the cart and checkout pages. The new total collector can be assigned to any area of the order totals, such as before or after the subtotal, shipping, or grand total.

Question 3

An Adobe Commerce Architect is investigating a case where some EAV product attributes are no longer updated.

* The catalog is composed of 20.000 products with 100 attributes each.

* The product updates are run by recurring Adobe commerce imports that happen multiple times a day.

* The Architect finds an error in the logs that indicates an integrity constraint while trying to insert row with id 2147483647.

What is causing this error?

AMagento framework uses INSERT on DUPLICATE, which leads to reaching the max limit of the increment of the column.

BIntegrity constraints were dropped after upgrading to the latest version, and the integrity checks were missed.

CEAV attribute import uses REPLACE, which leads to reaching the max limit of the increment of the column

Answer : C

EAV attribute import uses the REPLACE statement, which deletes and inserts a new row with the same primary key value. This causes the auto-increment column to increase by one for each row, even if the row already exists. If the auto-increment column reaches its maximum value, which is 2147483647 for a signed INT, then any further REPLACE statement will fail with an integrity constraint violation error.Reference:

Question 4

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?

Agroup property should be added with a value of 1

Bsystem property should be added with a value of true

Cscope property should be added with a value of global

Answer : A

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.Reference: https://experienceleague.adobe.com/docs/commerce-admin/customers/customer-accounts/attributes/attribute-properties.html?lang=en#group1

Question 5

An Adobe Commerce Architect needs to log the result of a ServiceClass:: getData method execution after all plugins have executed. The method is public, and there are a few plugins declared for this method. Among those plugins are after and around types, and all have sortOrder specified.

Which solution should be used to meet this requirement?

ADeclare a new plugin with the sortOrder value lower than the lowest declared plugin sortOrder and implement aroundGetData method.

BDeclare a new plugin with the sortOrder value higher than the highest declared plugin sortOrder and implement afterGetData method.

CDeclare a new plugin with the sortOrder value higher than the highest declared plugin sortOrder and implement aroundGetData method.

Answer : B

This solution ensures that the new plugin will execute after all the existing plugins for the ServiceClass::getData method, and will be able to log the final result of the method execution. The afterGetData method of the new plugin will receive the result of the method as a parameter, and can use any logging mechanism to record it. The sortOrder value of the new plugin should be higher than the highest declared plugin sortOrder, so that it will run last in the sequence of plugins. The after type of plugin is preferred over the around type of plugin, because it is simpler and more efficient, and does not require calling the proceed() method.

Question 6

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?

AModify project config.php file, configure 'admin_locales_for_deploy' value, and specify all required locales

BEdit project env.php file, configure 'adminJocales_for_build' value, and specify all required locales

CAdjust the tools build script and specify required locales during *setup:static-content:deploy' command

Answer : C

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.Reference: https://experienceleague.adobe.com/docs/commerce-cloud-service/user-guide/develop/deploy/static-content.html?lang=en#deploy-static-view-files1

Question 7

An Adobe Commerce store owner sets up a custom customer attribute "my.attribute".

An Architect needs to display additional content on the home page, which should display only to Customers with "my.attribute" of a certain value and be the same content for all of them. The website is running Full Page Cache.

With simplicity in mind, which two steps should the Architect take to implement these requirements? (Choose two.)

AAdd a new context value of 'my_attribute' to Magento\Framework\App\Http\Context

BCreate a Customer Segment and use 'my.attribute' in the conditions

CAdd a custom block and a pHTML template with the content to the cmsjndexjndex.xml layout

DAdd a dynamic block with the content to the Home Page

EUse customer-data JS library to retrieve 'my.attribute' value

Answer : A, D

To display additional content on the home page based on a custom customer attribute, the Architect needs to do the following steps:

Add a new context value of ''my_attribute'' to Magento\Framework\App\Http\Context. This will allow the Full Page Cache to generate different versions of the page for customers with different values of ''my.attribute''. The context value can be set using a plugin on the Magento\Customer\Model\Context class.

Add a dynamic block with the content to the Home Page. A dynamic block is a type of content block that can be configured to display only to specific customer segments or conditions. The Architect can use the 'my.attribute' in the conditions of the dynamic block and assign it to the Home Page in the Content > Blocks section of the Admin Panel.Reference:
