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.

The correct answers are A and C.

The errors in the snippet are:

Column roll_no does not have an index. It is needed since attribute_identity is set to true.

Column student_name does not have an attribute length.

The attribute_identity attribute specifies whether the primary key of the table should be auto-incremented. If attribute_identity is set to true, then the roll_no column must have an index. The student_name column does not have an attribute length, which is required for string columns.

The following code shows how to fix the errors:

Once the errors have been fixed, the table can be created successfully.

In Adobe Commerce Cloud, routing configurations for custom domains and subdomains are managed within the .magento/routes.yaml file. This file defines how requests are directed to the application and is essential for setting up different stores or websites with unique subdomains.

Using .magento/routes.yaml for Subdomain Configuration:

To set up a new subdomain, like secondstore.example.com, you need to configure the route in .magento/routes.yaml. This file handles all routing and domain configurations for Adobe Commerce Cloud projects.

Why Option C is Correct:

.magento/routes.yaml is designed specifically for defining routing rules, including subdomains, making it the appropriate choice for this task.

Option A (NGINX configuration) and Option B (.magento/services.yaml) are not correct because they don’t directly manage domain routing in Adobe Commerce Cloud.

Example Configuration:

http://secondstore.example.com/:

type: upstream

upstream: "mymagento:80"

The developer can update the Staging environment with the latest code from Production by logging in to the Project Web Interface, choosing the Staging environment, and clicking Sync. This will synchronize the code, data, and media files from Production to Staging, creating an exact copy of Production on Staging. The developer can then deploy the new release to Staging and test it before pushing it to Production. Verified References: [Magento 2.4 DevDocs]

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.

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.

The developer can extend the existing CartltemPrices GraphQL schema to include a custom base_price field by adding the following code to the module’s etc/schema.graphqls file:

extend type CartltemPrices { base_price: Money! @doc(description: “The base price of the cart item”) }

This code adds a new field called base_price to the CartltemPrices type and specifies that it is of type Money and it is not nullable. The @doc directive adds a description for the field that will be shown in the schema documentation. The developer also needs to create a custom resolver class for the base_price field and declare it in the di.xml file of the module.

The variable env: composer_auth is located in the Project variables section in the Project Web Interface. This variable is used to store the authentication credentials for Composer repositories that require access keys or tokens. The developer can set this variable at the project level to apply it to all environments, or override it at the environment level if needed.
