QUESTION: 5

An Adobe Commerce developer adds a new extension attribute to add an array of values to the invoices that are fetched through the APIs.
After a while, their technical manager reviews their work and notices something wrong with the extension_attributes. xml file that the developer created in their module:
What is the problem with this xml snippet?

The extension attribute references the wrong interface, it should have referenced the Magento\saies\Api\data\invoiceinterface.
The extension attribute references the repository instead of the interface it implements (Magento\saies\Api\invoiceRepositorymterface).
The type is wrong, string [] should be replaced with array.

Answer(s): B

Explanation:

The extension attribute is referencing the repository instead of the interface it implements. The correct XML snippet should be:
XML

<extension_attributes>
<attribute code="custom_values" type="string[]"
group="General"
translate="true">
<description>This attribute stores an array of custom values for the invoice.</description> <source_model>Magento\Sales\Api\Data\InvoiceInterface</source_model> </attribute>
</extension_attributes>
The source_model attribute specifies the interface that the extension attribute is associated with. In this case, the extension attribute is associated with the Magento\Sales\Api\Data\InvoiceInterface interface.

QUESTION: 6

An Adobe Commerce developer is creating a new console command to perform a complex task with a lot of potential terminal output. If an error occurs, they want to provide a message that has higher visibility than some of the other content that may be appearing, so they want to ensure it is highlighted in red (as seen in the screenshot):

How can they customize the appearance of this message?

Call the setDecorationType(Stype) method On the Symfony\Console\Output\OutputInterface Object before Calling writeln().
Wrap the output content in tags like <error>, <info>, or <comment>.
Throw a new commandException with the desired message passed as an argument.

Answer(s): A

Explanation:

The developer can customize the appearance of the error message by calling the setDecorationType() method on the Symfony\Console\Output\OutputInterface object before calling writeln(). The setDecorationType() method takes a single argument, which is the type of decoration that the developer wants to use. In this case, the developer wants to use the STYPE_ERROR decoration, which will highlight the message in red.
Here is an example of how to customize the appearance of the error message:

$output = new Symfony\Console\Output\ConsoleOutput();
$output->setDecorationType(Symfony\Console\Output\OutputInterface::STYPE_ERROR); $output->writeln('This is an error message.');

The output of this code will be an error message that is highlighted in red.

QUESTION: 8

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

If the Sodium extension is installed, SHA256 will be chosen, otherwise MD5 will be used as the Magento default hashing algorithm.
If the Sodium extension is installed, Argon 2ID13 will be chosen, otherwise SHA256 will be used as the Magento default hashing algorithm.
It does not matter if the Sodium extension is installed or not, the Magento hashing default algorithm will be SHA256.

Answer(s): B

Explanation:

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.
