AD0-E716 Exam Dumps - Adobe Commerce Questions and Answers

The Content Security Policy (CSP) in Adobe Commerce (Magento) restricts the types of content that can be loaded on a page to protect against malicious attacks, such as cross-site scripting (XSS). When an iframe is added, and a JavaScript library is loaded from an external source, these resources must be whitelisted explicitly using the csp_whitelist.xml file.

In this specific case:

The frame-src directive controls the sources from which iframes can be embedded. Since the developer is embedding an iframe from an external domain, they need to whitelist this domain for frame-src.

The script-src directive controls the sources from which JavaScript files can be loaded. The external JavaScript library must be whitelisted under script-src to allow it to execute.

Therefore, the correct policy IDs to whitelist are:

frame-src: to allow the embedding of content from an external domain in an iframe.

script-src: to allow the loading and execution of JavaScript files from the external domain.

Here’s how to update the csp_whitelist.xml file with the correct directives:

Replace your-external-domain.com with the actual domain of the external iframe and JavaScript source.

For a payment method to be available in the admin panel (backend), the configuration must explicitly allow its internal use. This is controlled by the can_use_internal flag in config.xml.

Configuration for Admin Use:

The can_use_internal flag determines if a payment method is available for admin users when placing orders from the backend. By default, this is often set to false for some custom payment methods, meaning they won’t appear in the admin.

Why Option C is Correct:

Setting can_use_internal to true makes the payment method available for backend order creation, which is why this is the most probable reason it isn’t visible in the admin.

Options A and B do not influence the payment method’s availability in the admin; they affect verification types and capture settings, respectively.

The developer can test the new feature under the integration environment by deactivating one of the active integration environment branches, creating a new active branch from integration and installing the module, and pushing the changes. This is because Enhanced Integration Environments have a limit of four active branches at a time, and each branch has its own dedicated database and services. The developer can use the Cloud CLI for Commerce tool to manage the branches and deploy the code changes. Verified References: [Magento 2.4 DevDocs] 1

Enhanced Integration Environments in Adobe Commerce Cloud have a limit on the number of active branches. If both integration branches are currently active, one must be deactivated to create a new active branch for testing.

Creating a New Active Integration Branch:

If there are already two active branches, deactivate one to free up space for a new branch.

Then create a new branch from the integration environment, apply the changes (such as installing the new module), and push the changes.

Why Option C is Correct:

Adobe Commerce Cloud limits the number of active integration branches. Deactivating an existing branch is necessary before creating a new active branch for testing.

Option A suggests duplicating a branch without addressing the active branch limitation, while Option B disregards the need to check branch active status, which could prevent successful deployment.

The correct answer is Option C. This XML configuration is the correct way to define allowed child content types for a slider content type in Magento's PageBuilder.

Magento PageBuilder Content Type Structure:

In PageBuilder, each content type can specify which other content types are allowed as children.

This is done by defining the allowed_children array within the content type’s XML configuration.

Analyzing Option C:

Arguments Definition: Option C uses the node to define a new argument named allowed_children.

Array Structure: This argument is an array (xsi:type="array") that includes an item specifying the improved_slide as an allowed child with xsi:type="string".

This configuration is correct because it explicitly defines which child content types are allowed for the slider content type, adhering to Magento’s structure for allowed child elements in PageBuilder.

Why Options A and B are Incorrect:

Option A: Uses a node with policy="allow", which is not the standard way to define allowed children for PageBuilder content types. This format is incorrect and won’t be recognized by PageBuilder.

Option B: Uses , which also doesn’t align with the way Magento’s PageBuilder expects child content types to be declared. The correct term is allowed_children, not allowed_descendants.

Option C’s configuration aligns with Adobe Commerce PageBuilder’s structure for defining which content types can be nested within another, making it the correct choice.

In Magento 2, to add a new action to a pre-existing route without interfering with the existing functionality, the new action should be placed in the same directory structure under the new module’s controller namespace. Magento's autoloading mechanism will automatically detect and include it alongside the original module's actions.

Here's how you can achieve this:

Directory Structure: Ensure that your new module's controller directory structure mirrors that of the original module.

Controller Action: Define the new action within the appropriate directory.

For example, if you want to add a new action to the catalog route in Magento_Catalog:

Create a directory structure app/code/My/Module/Controller/Catalog/.

Add your new action class in this directory, for example:

namespace My\Module\Controller\Catalog;

use Magento\Framework\App\Action\Action;

use Magento\Framework\App\Action\Context;

class NewAction extends Action

{

public function __construct(Context $context)

{

parent::__construct($context);

}

public function execute()

{

// Your custom logic here

}

}

Router Configuration: Magento automatically includes this action when the route matches.

By following this method, you ensure that your new action is added seamlessly without modifying the original module or causing conflicts. Magento's router will include and recognize your action based on the directory and namespace conventions.

The developer has to add a formkey for the new export option because the formkey is required for security reasons. Without the formkey, the request will be rejected and redirected to the dashboard page. Verified References: [Magento 2.4 User Guide] [Magento 2.4 DevDocs]

When adding custom export options to grids in Magento, it's crucial to include a form key for actions that involve form submission. Magento relies on form keys for CSRF (Cross-Site Request Forgery) protection, so omitting the form key can lead to redirects or failed operations.

Form Key Requirement:

In Magento, the form key is a hidden token included in forms to ensure that the request is valid. This is particularly important for actions that change the state or export data, as it helps prevent unauthorized actions.

Adding a custom export button triggers a form submission, which requires a valid form key. Without it, Magento may redirect to a default page or the admin dashboard as a security measure.

Why Option C is Correct:

Option C correctly identifies the lack of a form key as the issue. When Magento detects a missing form key in sensitive operations, it defaults to a redirect to maintain security.

Option A, concerning the URI, is less likely to cause a redirection. Similarly, Option B regarding layout cache would not directly impact CSRF validation, which is the cause of the redirection here.

Solution:

Modify the button or form submission logic to include a form key, typically by adding form_key={{formKey}} in the URL parameters or within the form data.

The developer can deal with this issue by modifying the admin path timeout value in seconds in the Fastly Configuration section > Advanced Configuration in the Admin Panel. Fastly is a cloud-based caching service that improves site performance and security for Adobe Commerce Cloud projects. Fastly has a default timeout value of 180 seconds for admin requests, which means that any request that takes longer than 180 seconds will be terminated and result in a timeout error. The developer can increase this value to allow longer processing time for admin requests without causing errors. The developer also needs to save the configuration and upload VCL to Fastly to apply the changes. Verified References: [Magento 2.4 DevDocs]

To ensure the developer has access to push code in an Adobe Commerce Cloud project, the developer’s email must be added under Users in the Cloud Project Web UI and the developer needs to add SSH public key in the Cloud Account dashboard settings. The Cloud Project Web UI is a web interface that allows managing and configuring Adobe Commerce Cloud projects and environments. The developer’s email must be added under Users to grant them access to the project and assign them a role and permissions. The Cloud Account dashboard settings is a web interface that allows managing and configuring Adobe Commerce Cloud accounts and SSH keys. The developer needs to add SSH public key in the settings to enable secure connection to the project and environments via SSH. Verified References: [Magento 2.4 DevDocs]

The developer should create an extension attribute on the Magento\Sales\Api\Data\OrderInterface interface and an after plugin on the Magento\Sales\Api\OrderRepositoryInterface::get() and Magento\Sales\Api\OrderRepositoryInterface::getList() methods.

The extension attribute will store the custom data. The after plugin will be used to add the custom data to the order object when it is fetched from the API.

Here is the code for the extension attribute and after plugin:

PHP

namespace MyVendor\MyModule\Api\Data;

interface OrderExtensionInterface extends \Magento\Sales\Api\Data\OrderInterface

{

/**

* Get custom data.

*

* @return string|null

*/

public function getCustomData();

/**

* Set custom data.

*

* @param string $customData

* @return $this

*/

public function setCustomData($customData);

}

namespace MyVendor\MyModule\Model;

class OrderRepository extends \Magento\Sales\Api\OrderRepositoryInterface

{

/**

* After get order.

*

* @param \Magento\Sales\Api\OrderRepositoryInterface $subject

* @param \Magento\Sales\Api\Data\OrderInterface $order

* @return \Magento\Sales\Api\Data\OrderInterface

*/

public function afterGetOrder($subject, $order)

{

if ($order instanceof OrderExtensionInterface) {

$order->setCustomData('This is custom data');

}

return $order;

}

/**

* After get list.

*

* @param \Magento\Sales\Api\OrderRepositoryInterface $subject

* @param \Magento\Sales\Api\Data\OrderInterface[] $orders

* @return \Magento\Sales\Api\Data\OrderInterface[]

*/

public function afterGetList($subject, $orders)

{

foreach ($orders as $order) {

if ($order instanceof OrderExtensionInterface) {

$order->setCustomData('This is custom data');

}

}

return $orders;

}

}

Once the extension attribute and after plugin are created, the custom data will be added to orders fetched from the API.

In Adobe Commerce, when defining new API endpoints through the webapi.xml configuration file, the visibility of these endpoints in tools like Swagger (now OpenAPI) depends on several factors, including authentication settings. According to the provided webapi.xml file:

xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Webapi:etc/webapi.xsd">

Option A suggests moving the file to etc/webapi_rest/webapi.xml. However, this is incorrect because Adobe Commerce does not require separate XML files for REST and SOAP APIs in this context. The webapi.xml is used for defining routes for both. The structure and location provided in the question are correct for defining REST API routes.

Option B is the correct answer. The resource reference MyVendor_Blog::Post_View indicates that this API endpoint is not anonymous; it requires authentication. In Adobe Commerce, if an API endpoint requires authentication, it won't be visible in Swagger (or the OpenAPI UI) unless you provide valid authentication credentials or tokens. This is part of Magento's security model where protected resources require tokens or OAuth to access. For the merchant to see this endpoint in Swagger, they must provide an integration token or OAuth token which has permissions for MyVendor_Blog::Post_View. This is detailed in the Adobe Commerce Developer Documentation under [Web API Authentication](https://x.com/i/grok?text=Web%20API%20Authentication) .

Option C mentions the @return annotation missing in the interface class. While proper annotations in PHPDoc are important for IDE autocompletion and documentation generation, they are not directly related to the visibility of an endpoint in Swagger. The visibility in Swagger is determined by the configuration in webapi.xml and the authentication settings, not by PHPDoc annotations. Thus, this option is incorrect in the context of the question.
