Yes it is part of the exam

Metamodel API allows you to use STRONGLY typesafe queries when using Java persistence interface.

A simple example is you won't refer to column names in your queries with the physical column names but you utilise the Metamodel class of the entity.

Each entity have a corresponding Metamodel class

tbl_persons.age (table_name.column_name)

Person_.age (Metamodel).
