Question 1

On an Adobe Commerce Cloud platform, what type of environment will be provisioned when launching the CLI for Commerce command magento-cloud environment:branch ?

AAn empty integration environment without any code or database.

BAn integration environment with fresh Adobe Commerce Cloud installation.

CAn integration environment with the code and database from the parent environment.

Answer : C

The type of environment that will be provisioned when launching the CLI for Commerce command magento-cloud environment:branch <environment-name> is an integration environment with the code and database from the parent environment. Integration environments are temporary environments that are used for testing and development purposes on the Adobe Commerce Cloud platform. They can be created from any branch of code and have their own dedicated database and services. When creating an integration environment using the CLI for Commerce command, the code and database from the parent environment are copied to the new integration environment, creating an exact replica of the parent environment.

Question 2

Which hashing algorithm will Adobe Commerce choose to hash customer passwords?

AIf the Sodium extension is installed, SHA256 will be chosen, otherwise MD5 will be used as the Magento default hashing algorithm.

BIf the Sodium extension is installed, Argon 2ID13 will be chosen, otherwise SHA256 will be used as the Magento default hashing algorithm.

CIt does not matter if the Sodium extension is installed or not, the Magento hashing default algorithm will be SHA256.

Answer : B

If the Sodium extension is installed, Argon 2ID13 will be chosen as the Magento default hashing algorithm. Otherwise, SHA256 will be used.

The Sodium extension is a PHP extension that provides cryptographic functions. Argon 2ID13 is a password hashing algorithm that is considered to be more secure than SHA256.

If the Sodium extension is installed, Magento will use Argon 2ID13 as the default hashing algorithm for customer passwords. If the Sodium extension is not installed, Magento will use SHA256 as the default hashing algorithm.

Question 3

An integration named Marketing is created on the Adobe Commerce instance. The integration has access on Magento_Customer:: customer resources and the access token is xxxxxx.

How would the rest API be called to search the customers?

AUsing the integration access token as Bearer:
curl -X GET https://magentourl/rest/Vl/customers/search?searchCriteria... -H 'Authorization: Bearer XXXXXX'

BPassing integration name and access token as http auth credentials:
curl -X GET https ://Marketing:XXXXXX(Slmagentourl/rest/Vl/customers/search?5earchCriteria . . .
Using integration name as username and access token as password, get the admin token (yyyyyy) via:
curl -X POST https://magentourl/rest/Vl/integration/admin/token -d '{'username':'Marketing', 'password':'XXXXXX'}' -H 'Content-

CType: application/json'
Use the admin token as Bearer
curl -X GET https://magentourl/rest/Vl/customers/search?searchCriteria... -H 'Authorization: Bearer YYYYYY'

Answer : B

According to the Magento Stack Exchange answer, UI components are used to render various elements on Magento admin pages, such as grids, forms, buttons, etc. UI components are defined in XML files that are located in the view/adminhtml/ui_component directory of each module. To add a custom logic to render a column in a grid, the developer should create a custom class extending MagentoUiComponentListingColumnsColumn and add the custom logic within the prepareDataSource method. This method receives an array of data sources and modifies them according to the column logic. The developer should also add an attribute class to the column node within the module's customer_listing.xml file and specify their custom class name as its value.

Question 4

An Adobe Commerce developer is about to deploy a critical feature to their Adobe Commerce Cloud (Pro Plan) production. They want to create a snapshot in order to be able to rollback if there is an issue with the feature.

How would they create the snapshot?

AUse the dedicated button on Project Web Interface.

BUse the Cloud CLI for Commerce dedicated command.

CCreate a ticket to Adobe Commerce Cloud support.

Answer : A

The developer can create a snapshot before deploying a critical feature to their Adobe Commerce Cloud (Pro Plan) production by using the dedicated button on Project Web Interface. A snapshot is a backup of an entire environment, including code, data, media files, and configuration settings. A snapshot can be used to restore an environment to a previous state in case of any issues or errors during deployment or testing. The developer can create a snapshot by accessing the Project Web Interface, choosing an environment, and clicking Create Snapshot. Verified Reference: [Magento 2.4 DevDocs]

Question 5

An Adobe Commerce developer has created a before plugin for the save() function within the

Magento\Framework\App\cache\Proxy class. The purpose of this plugin is to add a prefix on all cache identifiers that fulfill certain criteria.

Why is the plugin not executing as expected?

AAnother around plugin defined for the same function does not call the callable.

BCache identifiers are immutable and cannot be changed.

CThe target ClaSS implements Magento\Framework\ObjectManager\NoninterceptableInterface.

Answer : C

According to the Plugins (Interceptors) guide for Magento 2 developers, plugins are class methods that modify the behavior of public class methods by intercepting them and running code before, after, or around them. However, some classes in Magento 2 implement the NoninterceptableInterface interface, which prevents plugins from being generated for them. The Magento\Framework\App\cache\Proxy class is one of them, as it extends from Magento\Framework\ObjectManager\NoninterceptableInterface. Therefore, the plugin is not executing as expected because the target class implements NoninterceptableInterface.

Question 6

The di. xml file of a module attaches two plugins for the class Action.

The around plugin code is:

What would be the plugin execution order?

AOption A

BOption B

COption C

Answer : C

The plugin execution order is as follows:

PluginA::beforeDispatch()

PluginB::beforeDispatch()

PluginA::aroundDispatch()

The code in the around plugin

PluginB::afterDispatch()

PluginA::afterDispatch()

The aroundDispatch() method is executed in a separate scope, so the code in the around plugin will be executed after the beforeDispatch() methods of both plugins, but before the afterDispatch() methods of both plugins.

Here is a diagram that shows the plugin execution order:

PluginA

beforeDispatch()

aroundDispatch()

afterDispatch()

PluginB

beforeDispatch()

afterDispatch()

Question 7

An Adobe Commerce developer has added a new configuration field to the admin are

a. The path for this option is general/store_information/out_of_hours_phone.

Keeping simplicity in mind, how would the developer ensure this option contains a valid US telephone number?

AAdd <validate>phoneUS</validate> to the field in system.xml.

BCreate a backend model to check the validity of the phone number entered.

CAdd <validate type='phoneUS'/> to the field in system.xml.

Answer : A

According to the Magento Stack Exchange answer, system.xml is a file that defines the configuration fields for the admin area. Each field can have a validate attribute that specifies a validation rule for the field value. Magento provides some built-in validation rules, such as phoneUS, which validates a US telephone number. Therefore, to ensure that the option contains a valid US telephone number, the developer needs to add <validate>phoneUS</validate> to the field in system.xml.
