An Adobe Commerce developer has added a new configuration field to the admin area. The path for this option is general/store_information/out_of_hours_phone.
Keeping simplicity in mind, how would the developer ensure this option contains a valid US telephone number?
Correct Answer:A

Each field can have a validate attribute that specifies a validation rule for the field value. Magento provides some built-in validation rules, such as phoneUS, which validates a US telephone number. Therefore, to ensure that the option contains a valid US telephone number, the developer needs to add
<validate>phoneUS</validate> to the field in system.xml. Verified References:https://magento.stackexchange.com/questions/104570/magento-2-system-xml- validation-rules

The value of a product attribute in the Adobe Commerce system needs to have a different format before it is displayed. Which attribute model class is responsible for this?
Correct Answer:A
The frontend attribute model class is responsible for formatting the value of a product attribute before it is displayed on the storefront. This class can implement methods such as getValue, getLabel, getInputType, and getOptionText to modify the attribute value. The backend attribute model class is responsible for saving and loading the attribute value to and from the database. The source attribute model class is responsible for providing the list of options for an attribute.
Verified References: [Adobe Commerce Developer Guide - Attribute models]
In Adobe Commerce (Magento 2), the formatting of product attribute values before they are displayed is handled by the attribute's frontend model. The frontend model, typically extending\Magento\Eav\Model\Entity\Attribute\Frontend\AbstractFrontend, is responsible for preparing the attribute value for display in the frontend, including formatting dates, adding pricing structures, and more. The backend model deals with saving and loading attribute data, while the source model provides options for select attributes.
