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
OCPJP, OCEJWCD, OCEJPAD, OCEEJBD
It is sorta covered in the
