Question 1

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.

Sthis->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?

Answer Options

ACreate one test class with one test method. Use the \Magento\testFramework\ store\Executionstorecontext class once in the fixture and another time in the test.

BCreate two test Classes With one test method each. Use the @magentoExecuteInStoreContext 3 and @magentoExecuteInStoreContext 4 annotations on the class level.

CCreate one test class with two test methods. Use the @magentoStoreContext 3 annotation in one method and @magentoStoreContext 4 in the other one.

Correct Answer: C

Explanation

The @magentoStoreContext annotation allows the test to run in the context of a specific store view. This annotation can be used on the method level to specify different store views for different test methods. This way, the product creation and the tested logic will be executed in the context of the same store view for each test method.

Question 2

An Adobe Commerce Architect runs the PHP Mess Detector from the command-line interface using the coding standard provided with Adobe Commerce. The following output appears:

The Architect looks at the class and notices that the constructor has 15 parameters. Five of these parameters are scalars configuring the behavior of Kyservice.

How should the Architect fix the code so that it complies with the coding standard rule?

Answer Options

AIntroduce a new class accepting those five scalars and use it in the constructor and the remaining logic of Myservice

BModify the code of Myservice so the number of different classes, interfaces, and scalar types used as parameters in the constructor and other methods is less than 13

CModify the code of Myservice so that the number of different classes and interfaces referenced anywhere inside the class is less than 13

Correct Answer: A

Explanation

The best way to fix the code so that it complies with the coding standard rule is to introduce a new class accepting those five scalars and use it in the constructor and the remaining logic of Myservice. This will reduce the number of different classes, interfaces, and scalar types used as parameters in the constructor and other methods to less than 13, which is the limit set by the coding standard. Additionally, any extra code that is not necessary can be removed to reduce the general complexity of the class and improve readability.

The coding standard rule that is violated by the code is the Coupling Between Objects (CBO) metric. This metric measures the number of different classes and interfaces that a class depends on. A high CBO value indicates that the class is tightly coupled with other classes and interfaces, which makes it harder to maintain and test. The recommended CBO value for Adobe Commerce classes is less than 13. To reduce the CBO value of Myservice, the Architect should introduce a new class that encapsulates the five scalar parameters that configure the behavior of Myservice. This way, the constructor of Myservice will only depend on one additional class instead of five scalars, and the CBO value will be reduced by four.

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.)

Answer Options

AEnable price index customer group merging for products without tier prices

BSet Customer Share Customer Accounts Option to Global

CEdit customer groups to exclude websites that they are not using

DSet MaGE_INDEXER_THREADS_COUNT environment variable to enable parallel mode

EMove catalog price_index indexer to another custom indexer group

Correct Answer: A, D

Explanation

The two best ways the Architect can shorten the full price index execution time are Option A. Enable price index customer group merging for products without tier prices, and Option D. Set MaGEINDEXERTHREADS_COUNT environment variable to enable parallel mode. Enabling customer group merging will help reduce the number of customer groups that need to be processed, while setting the environment variable will allow the indexer to use multiple threads and run in parallel mode, thus reducing the overall execution time.

Enabling price index customer group merging allows Magento to merge the price index rows for products that have the same price for all customer groups. This reduces the number of rows in the price index table and improves the performance of the indexer. Setting the MaGE_INDEXER_THREADS_COUNT environment variable allows Magento to run the indexer in parallel mode, which splits the index into multiple batches and processes them simultaneously. This reduces the execution time of the indexer.

Question 4

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?

Answer Options

AUtilize the payment provider Iframe system to isolate content of the embedded frame from the parent web page.

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

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

Correct Answer: A

Explanation

The Architect should utilize the payment provider iframe system to isolate content of the embedded frame from the parent web page. This approach will reduce the list of controls identified in their Self-Assessment Questionnaire as much as possible to achieve PCI compliance for their existing Magento application. By using an iframe, the payment provider handles all customer-sensitive data and Magento does not store or process any cardholder data. This reduces the PCI scope and simplifies the compliance process. Option B is incorrect because utilizing the Advanced Encryption Standard (AES-256) algorithm to encrypt all customer-sensitive data from the payment module will not reduce the PCI scope, but rather increase it. Magento will still store and process cardholder data, which requires more controls and validation. Option C is incorrect because utilizing a trusted signed certificate issued by a Certification Authority (CA) to secure each connection made by the payment solution protocol via HTTPS will not reduce the PCI scope, but rather ensure the security of data transmission. Magento will still store and process cardholder data, which requires more controls and validation.

Question 5

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?

Answer Options

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

BSet the 'Stores > Configuration' option for 'Store Session Data Separately' to 'Yes' in the Adobe Commerce Admin Panel.

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

Correct Answer: C

Explanation

Checking app/etc/env.php and making sure that the Redis configuration for caches and session data use different database numbers is the next step. This is because using the same database number for both caches and session data can cause session data to be lost when flushing the cache storage. By using different database numbers, the session data can be isolated from the cache data and avoid being overwritten.See Use Redis for session storage in the Adobe Commerce Help Center1.
