To add a product type with custom pricing, the Architect needs to do the following steps:

Create a content of the etc/product_types.xml file that defines the new product type, its label, model, index priority, and price model.This file is used to register the new product type and its associated classes in Magento1.

Create a new price model that extends \Magento\Catalog\Model\Product\Type\Price and implements the custom pricing logic for the new product type.The price model is responsible for calculating the final price of the product based on various factors, such as special price, tier price, catalog price rules, etc2.

Create a custom type model that extends from the abstract Product Type model (\Magento\Catalog\Model\Product\Type\AbstractType) and overrides the methods related to the product type behavior, such as prepareForCart, getAssociatedProducts, etc.The type model defines how the product type interacts with other components, such as quote, order, cart, etc3.Reference:

Correct : B

This solution ensures that the new plugin will execute after all the existing plugins for the ServiceClass::getData method, and will be able to log the final result of the method execution. The afterGetData method of the new plugin will receive the result of the method as a parameter, and can use any logging mechanism to record it. The sortOrder value of the new plugin should be higher than the highest declared plugin sortOrder, so that it will run last in the sequence of plugins. The after type of plugin is preferred over the around type of plugin, because it is simpler and more efficient, and does not require calling the proceed() method.

Correct : C

The error is caused by the generated child class not being updated with the new dependency. Removing the generated child class will allow the system to generate a new child class with the correct dependency. The generated child class is a proxy class that extends the original controller class and overrides the constructor to inject the dependencies using the object manager. The generated child class is created when the system runs in developer mode with cache enabled, to avoid performance issues. However, when a new dependency is added to the original controller class, the generated child class does not reflect the change and causes a mismatch in the constructor arguments. Therefore, deleting the generated child class from the generated/code directory will solve the problem.

Correct : B

Using an iframe system for payment integration can help reduce the PCI scope and compliance burden for the merchant, as the payment data is collected and processed by the payment service provider (PSP) within the iframe, without touching the merchant's website or server. This way, the merchant can leverage the PSP's PCI certification and avoid storing or transmitting any sensitive cardholder data on their own system. The iframe also provides a secure barrier between the host webpage and the loaded page, preventing any access or manipulation of the payment data by malicious actors.To implement this approach, the merchant needs to embed the PSP's payment form in their checkout page using an iframe element, and configure the communication between the iframe and the host page using JavaScript123.

Correct : 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.
