A developer defined a new table in db.schema.xml while creating a new module.
What should be done to allow the removal of columns from the database when deleting them from db.schema.xml?
Correct : A
If a developer wants to allow the removal of columns from the database when deleting them from db.schema.xml, they need to define the removable columns in the db_schema_whitelist.json file. This file will tell Magento which columns can be removed from the database.
To allow columns to be removed from the database when they are deleted from db_schema.xml, they must be listed in the db_schema_whitelist.json file. This file acts as a reference for which database schema elements are safe to modify or delete, providing a safeguard against unintentional data loss during schema updates.

Which two methods add sorting to collections inherited from the \Magento\Framework\Model\ResourceModel\Db\Collection\AbstractCollection class? (Choose two.)
Correct : A, D
The two methods that add sorting to collections inherited from the \Magento\Framework\Model\ResourceModel\Db\Collection\AbstractCollection class are setOrder and addOrder. These methods allow adding one or more order clauses to a collection query.
The setSorting and addSorting methods do not exist in Adobe Commerce.
Verified Reference: [Adobe Commerce Developer Guide - Collections]
In Magento 2, collections inherited from \Magento\Framework\Model\ResourceModel\Db\Collection\AbstractCollection class can be sorted using the setOrder and addOrder methods. The setOrder method is used to set the order for a field in the collection, specifying the field by which to sort and the direction of the sorting (ASC or DESC). The addOrder method is similar but allows for adding multiple sorting orders to the collection, enabling more complex sorting scenarios. There are no setSorting or addSorting methods in the standard Magento 2 collection classes.

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 : 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 Reference: [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.
