Adobe AD0-E716 Adobe Commerce Developer with Cloud Add-on Exam Practice Test

Answer : C

The type of environment that will be provisioned when launching the CLI for Commerce command magento-cloud environment:branch <environment-name> is an integration environment with the code and database from the parent environment. Integration environments are temporary environments that are used for testing and development purposes on the Adobe Commerce Cloud platform. They can be created from any branch of code and have their own dedicated database and services. When creating an integration environment using the CLI for Commerce command, the code and database from the parent environment are copied to the new integration environment, creating an exact replica of the parent environment.

According to the Develop data and schema patches guide for Magento 2 developers, data patches are classes that contain data modification instructions. They are defined in a <Vendor>/<Module_Name>/Setup/Patch/Data/<Patch_Name>.php file and implement MagentoFrameworkSetupPatchDataPatchInterface. Data patches can also implement Patchversioninterface to specify the module version that the patch is associated with. The getVersion() method returns the module version as a string. To skip changes that were already applied via old format (install/upgrade scripts), the developer should implement Patchversioninterface and return 1.5.4 on the getVersion() method. This way, the data patch will only be applied if the module version is greater than or equal to 1.5.4.

Answer : A

The _transformAttrs class property array of the importer and exporter classes can be used to specify a serializer class for a particular attribute. The serializer class will be used to convert the attribute value from one format to another when the data is exported or imported.

In this case, the developer can specify a serializer class that will convert the JSON data in the media_gallery attribute to a string. This will prevent the software that the client is using to modify the exported data from changing the JSON data.

The following code shows how to specify a serializer class for the media_gallery attribute:

PHP

class MySerializer

{

public function serialize($value)

{

return json_encode($value);

}

public function deserialize($value)

{

return json_decode($value);

}

}

$importer->setSerializer('media_gallery', MySerializer::class);

$exporter->setSerializer('media_gallery', MySerializer::class);

Once the serializer class has been specified, the JSON data in the media_gallery attribute will be converted to a string when the data is exported or imported. This will prevent the software that the client is using to modify the exported data from changing the JSON data.

Answer : C

The input_type attribute of a product EAV attribute specifies the type of input field that will be used to enter the value of the attribute in the admin panel. The textarea input type is used for WYSIWYG fields. If the input_type attribute is not set to textarea, then the attribute will not appear as WYSIWYG in the admin panel.

To fix this, the developer should set the input_type attribute to textarea.

Answer : A, C

The correct answers are A and C.

The errors in the snippet are:

Columnroll_nodoes not have an index. It is needed sinceattribute_identityis set totrue.

Columnstudent_namedoes 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:

XML

<table name='vendor_module_table'>

<entity_id>

<type>int</type>

<identity>true</identity>

<unsigned>true</unsigned>

<nullable>false</nullable>

</entity_id>

<roll_no>

<type>int</type>

<identity>false</identity>

<unsigned>true</unsigned>

<nullable>false</nullable>

true

<index>true</index>

</roll_no>

<student_name>

<type>string</type>

<length>255</length>

<nullable>false</nullable>

</student_name>

</table>

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

Answer : C

According to the Declarative Schema Overview guide for Magento 2 developers, declarative schema is a new feature that allows developers to declare the final desired state of the database and has the system adjust to it automatically, without performing redundant operations. However, declarative schema does not support uninstalling modules or reverting changes. To remove a table when a module is disabled, the developer needs to add a schema patch that implements Magento\Framework\setup\Patch\PatchRevertabieinterface and drops the table in the revert function. The revert function will be executed when the module is disabled using bin/magento module:disable command.

Answer : A

To allow the is_delayed EAV attribute to be used in the .phtml cart page, the developer needs to create a new file called etc/catalog_attributes.xmi. This file will contain the definition of the is_delayed attribute.

The following code shows how to create the etc/catalog_attributes.xmi file:

XML

<?xml version='1.0'?>

<catalog_attributes>

<label>Is Delayed</label>

<note>This attribute indicates whether the product is delayed.</note>

<sort_order>10</sort_order>

<required>false</required>

</catalog_attributes>

Once the etc/catalog_attributes.xmi file has been created, the is_delayed attribute will be available in the .phtml cart page. The attribute can be accessed using the getIsDelayed() method of the Product class.

PHP

$product = $block->getProduct();

$isDelayed = $product->getIsDelayed();

The isDelayed variable will contain the value of the is_delayed attribute. If the value of the attribute is 1, then the product is delayed. If the value of the attribute is 0, then the product is not delayed.
