Adobe AD0-E722 Exam Questions

Option A is correct because enabling the config flag under deployment/blue_green/enabled is one of the steps to ensure zero downtime during the deployment process of Magento 2 on-premises. This flag enables the blue-green deployment feature, which allows deploying a new version of the Magento application to a separate environment (blue) without affecting the current live environment (green).Once the new version is ready, the traffic can be switched from green to blue with minimal or no downtime1.

Option C is correct because running bin/magento setup:upgrade --keep-generated is another step to ensure zero downtime during the deployment process of Magento 2 on-premises. This command updates the database schema and data without deleting the generated code and static view files.This way, the Magento application can still serve requests from the cache while the database is being upgraded2.

Option B is incorrect because running bin/magento setup:upgrade --dry-run=true does not upgrade the database, but only checks if there are any errors or conflicts in the database schema or data.This command can be used for testing purposes, but it does not affect the deployment process or the downtime3.

Option D is incorrect because there is no such option as --convert-old-scripts-true for the bin/magento setup:upgrade command. This option does not exist in Magento 2 and does not have any effect on the deployment process or the downtime.

Option E is incorrect because there is no such config flag as developer/zero_down_time/enabled in Magento 2. This flag does not exist in Magento 2 and does not have any effect on the deployment process or the downtime.

Option B is a valid solution because creating a new HTTP Context variable can allow for differentiating the public content cache for users who belong to a B2B company account.The HTTP Context variable can be used to modify the output of the header block accordingly, without affecting the performance or scalability of the site1

Option D is also a valid solution because creating a new custom condition for customer segments can enable targeting users who are part of a B2B company account. The customer segment can be used to modify the output of the header block accordingly, using layout updates or dynamic blocks.This solution can also leverage the existing customer segment functionality and avoid custom coding2

Option A is not a valid solution because switching the theme based on a virtual type can cause performance issues and increase the complexity of the site maintenance.Moreover, switching the theme can affect the entire site appearance, not just the header block3

Option C is not a valid solution because using the customer session data directly to modify the output of the header block can prevent the public content cache from working properly.The customer session data is private and cannot be cached, so this solution can negatively impact the performance and scalability of the site4

Option E is not a valid solution because checking if the current user is part of a B2B company within a block class can also prevent the public content cache from working properly.The block class logic is executed on every request, so this solution can negatively impact the performance and scalability of the site5

The Architect can take the following steps to ensure validation of the configuration files with unique validation rules for the individual and merged files:

Create validation rules in marketplace.schema.xsd. This file defines the structure and constraints of the XML elements and attributes for the marketplace.feeds.xml configuration file. The Architect can use this file to specify the required and optional elements, data types, values, and patterns for the configuration file.

Provide schema to validate a merged file. This schema is used to validate the final configuration file that is generated after merging all the individual configuration files from different modules. The Architect can use this schema to check the consistency and completeness of the merged configuration file.

Provide schema to validate an individual file. This schema is used to validate each individual configuration file from each module before merging them. The Architect can use this schema to check the syntax and validity of each configuration file.

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:

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);

}
