A store needs to have a custom product attribute of type multiselect, so the Adobe Commerce developer created it via Data patch. The attribute was successfully created with provided backend & frontend models:
$catalogSetup = $this->categorySetupFactory->create([‘setup’ => $this->moduleDataSetup]);
$attrParams = [
‘type’ => ‘text’,
‘label’ => ‘Types of skin’,
‘input’ => ‘multiselect’,
‘required’ => 0,
‘visible_on_front’ => 1,
‘global’ => 0,
‘backend’ => MagentoEavModelEntityAttributeBackendArrayBackend::class,
‘frontend’ => MagentoEavModelEntityAttributeFrontendDefaultFrontend::class,
‘option’ => [‘values’ => [
‘Sensitive’,
‘Dry’,
‘Oily’,
‘Scaly’
]]
];
$catalogSetup->addAttribute(‘catalog_product’, ‘skin_types’, $attrParams);
Later the developer noticed that a custom frontend model class is needed to perform some actions before returning the value, so another data patch is added to update the attribute:
$catalogSetup = $this->categorySetupFactory->create([‘setup’ => $this->moduleDataSetup]);
$attrParams = [
‘frontend’ => VendorNameCustomModuleModelEntityAttributeFrontendHtmlList::class
];
$catalogSetup->updateAttribute(‘catalog_product’, ‘skin_types’, $attrParams);
Unfortunately, the frontend model changes were not applied.
What would be the possible issue?
- A . For compatibility purposes, the new frontend model class should extend from MagentoEavModelEntityAttributeFrontendDefaultFrontend.
- B . The attribute parameter name should be frontend_model rather than frontend.
- C . Another parameter frontend_class with class name VendorNameCustomModuleModelEntityAttributeFrontendHtmlList should be passed.
- D . The frontend model requires a corresponding entry in catalog_attributes.xml to apply changes.

An Adobe Commerce developer is training a junior developer on their team and is explaining how Data and Schema patches work. While investigating an example patch from the Adobe Commerce dev docs, the junior developer asks what the purpose of the startSetup and endSetup calls are from this method:
public function apply()
{
$this->moduleDataSetup->getConnection()->startSetup();
//The code that you want apply in the patch
//Please note, that one patch is responsible only for one setup version
//So one UpgradeData can consist of few data patches
$this->moduleDataSetup->getConnection()->endSetup();
}
Which two statements are true regarding the purpose of these methods? (Choose two.)
- A . startSetup sets the sql_mode system variable to NO_AUTO_VALUE_ON_ZERO and endSetup sets it back to”.
- B . startSetup sets the connect_timeout system variable to 600 (i.e., 10 minutes) to avoid lost connections for complex actions and endSetup returns it to the default.
- C . startSetup halts any running indexes or cron tasks to ensure the subsequent process is not interfered with and endSetup re-triggers them.
- D . startSetup sets the foreign_key_checks system variable to 0 and endSetup sets it back to 1.
Which steps are involved in correctly applying observers in Adobe Commerce to monitor and react to specific events? (Choose three)
