Question 1

An Adobe Commerce Architect is investigating a case where some EAV product attributes are no longer updated.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 2

While reviewing a newly developed pull request that refactors multiple custom payment methods, the Architect notices multiple classes that depend on \Magento\Framework\Encryption\EncryptorInterface to decrypt credentials for sensitive dat

a. The code that is commonly repeated is 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?

ACreate a common config service class vndor\Pay-ient\Gatway\conf ig\conf ig under Vendor.Payment and use it as a parent class for all of the

BReplace all Vendor\PaymentModule\Gateway\Config\Config ClaSSeS With virtualType Of Magento\Payiaent\Gateway\Conf ig\Conf ig and Set <user_secret backend_Model='Magento\Config\Model\Config\Backend\Encrypted' /> Under config.xml

CAdd a plugin after the getvalue method of $scopeConfig, remove the $encryptor from dependency and use it in the plugin to decrypt the value if the config name is user.secret'

Answer : B

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 avoid redundant dependency and duplicate code among the methods. The virtualType of Magento\Payment\Gateway\Config\Config will inherit the functionality of the base class and allow the customization of the constructor arguments, such as the pathPattern and valueHandlerPool.The backend_Model attribute of the user_secret field will specify that the value of this field should be encrypted and decrypted by the Magento\Config\Model\Config\Backend\Encrypted class, which implements the \Magento\Framework\App\Config\ValueInterface interface and uses the \Magento\Framework\Encryption\EncryptorInterface internally12.This way, the payment modules do not need to depend on the \Magento\Framework\Encryption\EncryptorInterface or the \Magento\Framework\App\Config\ScopeConfigInterface directly, and can use the getValue method of the Magento\Payment\Gateway\Config\Config class to get the decrypted value of the user_secret field3.Reference:

Question 3

An Architect is investigating a deployment issue with a server that is configured to work under the symlink directory /var/www/current, which lead to the latest released version of the application.

The deployment process performs the following steps:

After the last deployment, the merchant reported that the Adobe Commerce Import/Export functionality to export Customer Main File data is not working. The Architect discovered that the export file is not shown in the list of generated files.

Which change to the deployment process should be performed to solve this issue?

ARestart the consumer process during deployment to use the directory with a new application version for export files.

BExecute Command config:set export/customr/files_directory /var/releases/{release_nunber} to Set the new export path.

CDoable Crontab before deployment and re-launch after deployment.

Answer : B

The issue is that the export file is not shown in the list of generated files. This is because the export path is not set correctly. The solution is to execute the command config:set export/customr/files_directory /var/releases/{release_nunber} to set the new export path.This will ensure that the export file is saved in the correct directory and can be accessed from the Admin Panel.Reference: https://experienceleague.adobe.com/docs/commerce-cloud-service/user-guide/develop/deploy/staging-production.html?lang=en#deploy-to-staging-and-production1

Question 4

While developing a new functionality for a website in developer mode with all cache types enabled, an Adobe Commerce Developer needs to add \Magento\Sales\Model\Service\InvoiceService SinvoiceService as a new dependency to an existing page action controller in Vendor\CustomModule\Controller\Index\Index . This is accomplished as follows:

After cleaning the f ull_page cache and reloading the page, the developer encounters the following exception:

Recoverable Error: Argument 2 passed to Vendor\CustomModule\Controller\Index\Index::__construct() must be an instance of

\Magento\Sales\Model\Service\InvoiceService [...]

Which action should the Architect recommend to the developer to fix this error?

AClean the block_html cache along with full_page cache.

BAdd the new \Magento\sales\Model\service\invoiceService Sinvoiceservice dependency at the end of the constructor signature.

CRemove the generated Child ClaSS from generated/code/Vendor/CustomModule/Controller/Index/Index.

Answer : C

The error is caused by the generated child class not being updated with the new dependency. Removing the generated child class will allow the system to generate a new child class with the correct dependency. The generated child class is a proxy class that extends the original controller class and overrides the constructor to inject the dependencies using the object manager. The generated child class is created when the system runs in developer mode with cache enabled, to avoid performance issues. However, when a new dependency is added to the original controller class, the generated child class does not reflect the change and causes a mismatch in the constructor arguments. Therefore, deleting the generated child class from the generated/code directory will solve the problem.

Question 5

An Architect needs to create an additional regional UK website with its own website currency set to GBP in Adobe Commerce. An existing US website is using USD as a default base and website currency.

After the first week of sales in the new UK website, an administrator notices that all sales totals in Sales Orders report show 0.00.

How should this issue be resolved?

AConfigure currency rates for GBP and USD, so they are not empty.

BRefresh Lifetime Statistics for 'Total Invoiced'.

CMake sure that orders are shipped and not left in processing state.

Answer : A

The issue here is that the sales totals in Sales Orders report show 0.00 for the new UK website. This is because the currency rates for GBP and USD are not configured, so the system cannot convert the order amounts from GBP to USD. The solution is to configure the currency rates for GBP and USD, so they are not empty.This will allow the system to calculate the sales totals in USD for the report.Reference: https://experienceleague.adobe.com/docs/commerce-admin/stores-sales/site-store/currency/currency-update.html?lang=en1

Question 6

A representative of a small business needs an Adobe Commerce Architect to design a custom integration of a third-party payment solution. They want to reduce the list of controls identified in their Self-Assessment Questionnaire as much as possible to achieve PCI compliance for their existing Magento application.

Which approach meets the business needs?

AUtilize the Advanced Encryption standard (aes-256) algorithm to encrypt all customer-sensitive data from the payment module.

BUtilize the payment provider iframe system to isolate content of the embedded frame from the parent web page.

CUtilize a trusted signed certificate issued by a Certification Authority (CA) to secure each connection made by the payment solution protocol via https.

Answer : B

Using an iframe system for payment integration can help reduce the PCI scope and compliance burden for the merchant, as the payment data is collected and processed by the payment service provider (PSP) within the iframe, without touching the merchant's website or server. This way, the merchant can leverage the PSP's PCI certification and avoid storing or transmitting any sensitive cardholder data on their own system. The iframe also provides a secure barrier between the host webpage and the loaded page, preventing any access or manipulation of the payment data by malicious actors.To implement this approach, the merchant needs to embed the PSP's payment form in their checkout page using an iframe element, and configure the communication between the iframe and the host page using JavaScript123.

Question 7

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?

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

BThe developer forgot to use the getContentStagingValue method to retrieve the active campaign value of the product data.

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

Answer : C

Option C is correct because the developer did not check for an active content staging campaign and emulate the campaign state when retrieving product data. Content staging campaigns can modify the product data such as price, name, description, and so on, based on a schedule.To get the correct product data for a specific date and time, the developer needs to use the Magento\Staging\Model\VersionManager class to set the current version ID and emulate the campaign state1. Otherwise, the product data will be retrieved from the default store view without applying the campaign changes.

Option A is incorrect because retrieving product data directly from the database using the entity_id column is not necessarily wrong. It may not be the best practice, but it does not cause the feed output to be incorrect for products in the content staging campaign.The content staging campaigns are stored in separate tables with a version ID that links to the main product table2. The developer can still join these tables and query the product data based on the version ID and date.

Option B is incorrect because there is no such method as getContentStagingValue in Magento 2. The developer cannot use this method to retrieve the active campaign value of the product data. The correct way to get the product data for a specific campaign is to use the Magento\Staging\Model\VersionManager class as mentioned above.
