The questions for AD0-E722 were last updated On Apr. 21, 2024

Question #1

Due to a marketing campaign, a website is experiencing a very large number of simultaneously placed orders, which is affecting checkout performance. The website is in the production deploy mode.

Which two website settings can an Architect optimize to decrease the impact on checkout performance? (Choose two.)

Reveal Solution Hide Solution
Correct Answer: A, C

Option A is correct because enabling asynchronous indexing can improve the checkout performance by reducing the database load and avoiding locking issues. Asynchronous indexing allows the indexers to run in the background without affecting the frontend operations.The commandbin/magento config:set dev/grid/async_indexing 1can be used to enable this option in the production mode1.

Option C is correct because creating a new database and splitting the sales tables can also improve the checkout performance by distributing the database load and avoiding contention. Splitting the database allows the checkout and order management operations to use a separate master database from the rest of the Magento application tables.The commandbin/magento setup:db-schema:split-sales --host='<checkout db host or ip>' --dbname='<name>' --username='<checkout db username>' --password=''can be used to configure this feature2.

Option B is incorrect because enabling asynchronous email notifications does not affect the checkout performance directly. Asynchronous email notifications allow the order confirmation emails to be sent in batches by a cron job instead of immediately after placing an order.This option can reduce the server load and improve the customer experience, but it does not impact the checkout process itself3.

Option D is incorrect because there is no such deploy mode as siege in Magento 2. The available deploy modes are default, developer, and production.Changing the deploy mode can affect the performance, caching, and error handling of the Magento application, but it does not directly affect the checkout performance4.

Option E is incorrect because there is no such admin panel setting as multithreaded checkout processing in Magento 2. The number of PHP threads used for checkout is determined by the web server configuration and the PHP-FPM settings, not by the Magento application settings.Increasing the number of PHP threads may improve the checkout performance, but it also requires more server resources and may cause other issues5.

Question #2

An Architect agrees to improve company coding standards and discourage using Helper classes in the code by introducing a new check with PHPCS.

The Architect creates the following:

* A new composer package under the AwesomeAgency\CodingStandard\ namespace

* The ruleset. xml file extending the Magento 2 Coding Standard

What should the Architect do to implement the new code rule?

A)

B)

C)

Reveal Solution Hide Solution
Correct Answer: C

Option C is correct because adjusting the ruleset.xml file with the new rule is the simplest and most effective way to implement the new code rule. The ruleset.xml file defines the coding standards that are applied by PHP_CodeSniffer. By extending the Magento 2 Coding Standard and adding a new rule, the Architect can customize the code analysis and enforce the company coding standards.The new rule can use the Magento2.Namespaces.ForbiddenNamespaces sniff to check for any usage of Helper classes in the code and report them as errors or warnings1.

Option A is incorrect because creating a new composer package under the AwesomeAgency\CodingStandard\ namespace is not enough to implement the new code rule. The composer package is just a way to distribute and install the coding standard, but it does not define the rules themselves.The Architect still needs to create a ruleset.xml file and register it with PHP_CodeSniffer2.

Option B is incorrect because creating a new class \AwesomeAgency\CodingStandard\Ruleset\ForbiddenNamespaces and specifying the rule inside the process method is unnecessary and complicated. The Architect does not need to create a new class or a new sniff for this rule, as there is already an existing sniff in the Magento 2 Coding Standard that can be used for this purpose.The Magento2.Namespaces.ForbiddenNamespaces sniff can be configured with an include-pattern element to specify which namespaces are forbidden1.

Question #3

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?

Reveal Solution Hide 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);

}
