AD0-E716 Adobe Commerce Developer Expert Questions and Answers

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.

Theattribute_identityattribute specifies whether the primary key of the table should be auto-incremented. Ifattribute_identityis set totrue, then theroll_nocolumn must have an index. Thestudent_namecolumn 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.

To add a custom fixture to test a MyVendor_MyModule, the developer needs to do the following:

• Create a PHP file with the fixture data in [magento root dir]/dev/tests/integration/testsuite/MyVendor/MyModule/_files/my_fixture.php.
• Add the following annotation to the test method:

@magentoDataFixture(

'testsuite/MyVendor/MyModule/_files/my_fixture.php'

)

This will tell Magento to load the fixture data from themy_fixture.phpfile before the test method is executed.

To ensure that the configuration is deployed and consistent across all environments, the developer can use the following steps:

• Create a data patch that contains the configuration for the new website.
• Deploy the data patch to all environments.
• Use the magento deploy:status command to verify that the configuration has been deployed to all environments.

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 //Setup/Patch/Data/.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.

ThestartEnvironmentEmulation()method resets the translation locale to the one of the emulated stores, which overrides the locale the developer has set when the order ofsetLocale()andstartEnvironmentEmulation()is used as displayed above.

The correct way to achieve the desired result is to use theemulate()method to temporarily modify the translation locale. The following code shows how to do this:

PHP

$this->_translate->emulate('en_US');

// Render the template

$this->_translate->revert();

This code will set the translation locale to English before rendering the template, and then revert the locale back to the default value after the template has been rendered.

ThestartEnvironmentEmulation()method is used to emulate a different store view or website. This can be useful for testing purposes, or for developing features that need to work in different environments.

Theemulate()method is used to temporarily modify the translation locale. This can be useful for rendering templates in a specific language, or for testing features that need to work in different languages.

The probable cause for the delay in reflecting the changes on the frontend after a full product import is the combination of the number of products, customer groups and websites. This leads to a huge amount of values being stored in the price index which is too large to be processed at a normal speed. The price index calculates the final price of each product for each customer group and website, taking into account various factors such as tax, discounts, catalog price rules, etc. When there are many products, customer groups and websites, the price index becomes very complex and time-consuming to update.
