QUESTION: 17

While developing a new functionality for a website in developer mode with all cache types enabled, an Adobe Commerce Developer needs to add \Magento\Sales\Model\Service\InvoiceService SinvoiceService as a new dependency to an existing page action controller in Vendor\CustomModule\Controller\Index\Index . This is accomplished as follows:

After cleaning the f ull_page cache and reloading the page, the developer encounters the following exception:
Recoverable Error: Argument 2 passed to
Vendor\CustomModule\Controller\Index\Index::__construct() must be an instance of \Magento\Sales\Model\Service\InvoiceService [...]
Which action should the Architect recommend to the developer to fix this error?

Clean the block_html cache along with full_page cache.
Add the new \Magento\sales\Model\service\invoiceService Sinvoiceservice dependency at the end of the constructor signature.
Remove the generated Child ClaSS from generated/code/Vendor/CustomModule/Controller/Index/Index.

Answer(s): C

Explanation:

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.

QUESTION: 18

A representative of a small business needs an Adobe Commerce Architect to design a custom integration of a third-party payment solution. They want to reduce the list of controls identified in their Self-Assessment Questionnaire as much as possible to achieve PCI compliance for their existing Magento application.

Which approach meets the business needs?

Utilize the Advanced Encryption standard (aes-256) algorithm to encrypt all customer-sensitive data from the payment module.
Utilize the payment provider iframe system to isolate content of the embedded frame from the parent web page.
Utilize a trusted signed certificate issued by a Certification Authority (CA) to secure each connection made by the payment solution protocol via https.

Answer(s): B

Explanation:

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.

QUESTION: 19

A merchant asks for a new category attribute to allow uploading an additional mobile image against categories. The merchant utilizes the content staging and preview feature in Adobe Commerce and wants to schedule and review changes to this new mobile image field. A developer creates the attribute via a data patch and adds it to view/adminhtml/ui_component/category_f orm. xml. The attribute appears against the category in the main form, but does not appear in the additional form when scheduled updates are made. To change this attribute when scheduling new category updates, which additional action should the Architect ask the developer to take?

The attribute must have its apply_to field set to "staging" in the data patch file.
The attribute must have <item- name=''allow_staging" xsi:type=''boolean''>true</item> set in the cjt.gopy_for-.xni file under the attributes config' section.
The attribute must also be added to view/adminhtml/ui_co- component/catalogstaging_category_update_form.xml.

Answer(s): C

Explanation:

This action is necessary to make the attribute available for content staging and preview. According to the Adobe Commerce documentation, the catalogstaging_category_update_form.xml file defines the fields that are displayed in the Scheduled Changes section of the category form. The file extends the category_form.xml file and adds additional fields that are specific to content staging, such as start and end dates, campaign name, description, etc. To include a custom category attribute in the Scheduled Changes section, the attribute must also be declared in the catalogstaging_category_update_form.xml file with the same configuration as in the category_form.xml file.

QUESTION: 20

An Adobe Commerce Architect needs to create a new customer segment condition to enable admins to specify an Average sales amount' condition for certain segments.
The Architect develops the custom condition under
Vendor\Module\Model\Segment\Condition\AverageSalesAmount with all of its requirements:

During testing, the following error appears:

What should the Architect do to fix the problem?

A)

B)

C)

Option A
Option B
Option C

Answer(s): B

Explanation:

The error is caused by the missing class declaration for the custom condition class. According to the Adobe Commerce documentation, to create a custom customer segment condition, the class must extend the \Magento\CustomerSegment\Model\Condition\AbstractCondition class and implement the \Magento\CustomerSegment\Model\Condition\Combine\Interface interface. The class must also declare its name, label, value type, and attribute code properties. Option B is the only option that correctly declares the class with the required properties and inheritance. Option A and Option C are incorrect because they do not extend the AbstractCondition class or implement the

CombineInterface interface, and they do not declare the name, label, value type, or attribute code properties.
