Question #1

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.

Reveal Solution

Correct 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 #2

An Architect wants to create an Integration Test that does the following:

* Adds a product using a data fixture

* Executes $this->someLogic->execute($product) on the product

* Checks if the result is true.

$this->someLogic has the correct object assigned in the setup() method.

Product creation and the tested logic must be executed in the context of two different store views with IDs of 3 and 4, which have been created and are available for the test.

How should the Architect meet these requirements?

ACreate two test classes with one test method each. Use the @magentoExecuteinstoreContext 3 and $MagentoExecuteinStoreContext 4 annotations on the class level.

BCreate one test class with two test methods. Use the emagentostorecontext 3 annotation in one method and amagentostorecontext 4 in the other one.

CCreate one test class with one test method. Use the \Magento\TestFramework\store\ExecuteinstoreContext class once in the fixture and another time in the test.

Reveal Solution

Correct Answer: C

To create an integration test that executes different logic in different store views, the Architect needs to do the following steps:

Create one test class that extends \Magento\TestFramework\TestCase\AbstractController or \Magento\TestFramework\TestCase\AbstractBackendController, depending on the type of controller being tested1.

Create one test method that uses the @magentoDataFixture annotation to specify the data fixture file that creates the product2.

Use the \Magento\TestFramework\Store\ExecuteInStoreContext class to execute the fixture and the tested logic in different store views. This class has a method called executeInStoreContext, which takes two parameters: the store ID and a callable function.The callable function will be executed in the context of the given store ID, and then the original store ID will be restored3. For example:

PHPAI-generated code. Review and use carefully.More info on FAQ.

public function testSomeLogic()

{

// Get the product from the fixture

$product = $this->getProduct();

// Get the ExecuteInStoreContext instance from the object manager

$executeInStoreContext = $this->_objectManager->get(\Magento\TestFramework\Store\ExecuteInStoreContext::class);

// Execute the fixture in store view 3

$executeInStoreContext->executeInStoreContext(3, function () use ($product) {

// Do some operations on the product in store view 3

});

// Execute the tested logic in store view 4

$result = $executeInStoreContext->executeInStoreContext(4, function () use ($product) {

// Call the tested logic on the product in store view 4

return $this->someLogic->execute($product);

});

// Assert that the result is true

$this->assertTrue($result);

}

Question #3

An Adobe Commerce Architect notices that the product price index takes too long to execute. The store is configured with multiple websites and dozens of customer groups.

Which two ways can the Architect shorten the full price index execution time? (Choose two.)

ASet mage_ihdexer_threads_COUNT environment variable to enable parallel mode

BMove catalog_Price_index indexer to another custom indexer group

CEnable price index customer group merging for products without tier prices

DSet Customer Share Customer Accounts Option to Global

EEdit customer groups to exclude websites that they are not using

Reveal Solution

Correct Answer: A, C

The product price index can be optimized by using parallel mode and customer group merging. Parallel mode allows the indexer to run multiple threads simultaneously, which can speed up the indexing process. Customer group merging reduces the number of rows in the price index table by merging customer groups that have the same product prices. This can improve the performance of the price index queries and reduce the index size.Reference:Indexing optimization,Price index customer group merging

Question #4

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'

Reveal Solution

Correct 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 #5

Since the last production deployment, customers can not complete checkout.

The error logs show the following message multiple times:

main.CRITICAL: Report ID: webapi-61b9fe83f0c3e; Message: Infinite loop detected, review the trace for the looping path

The Architect finds a deployed feature that should limit delivery for some specific postcodes.

The Architect sees the following code deployed in etc/webapi_rest/di. xml and etc/frontend/di. Xml

LimitRates.php:

Which step should the Architect perform to solve the issue?

AChange 'after' plugin with 'around' plugin. The issue is being caused by calling the result provider code after the code of the original method.

BReplace the injected dependency Of \Magento\Checkout\Model\Session With \Magento\FraBievork\Session\SessionManagerInterf ace

CInject an instance Of Magento\(Quote\Api\CartRepositoryInterface and receive Cart instance Via $thiscartRepository->get($this->session->getQuoteId())
