May I please know if the following chapters need not be studied for the Exams?
The following chapters of 'EJB Core contracts and Specifications'.
Chapter 7 Client View of an EJB 2.1 Entity Bean
Chapter 8 EJB 2.1 Entity Bean Component Contract for Container-Managed Persistence
Chapter 9 EJB QL: EJB 2.1 Query Language for Container-Managed Persistence Query Methods
Chapter 10 EJB 2.1 Entity Bean Component Contract for Bean-Managed Persistence

Regarding, EJB 2.x, the following objective is written:
Identify correct and incorrect statements or examples about EJB 3.0 / EJB 2.x interoperability, including how to adapt an EJB 3.0 bean for use with clients written to the EJB 2.x API and how to access beans written to the EJB 2.x API from beans written to the EJB 3.0 API.
Would it suffice if I can just access an EJB 2.x bean from 3.0 bean?
