A,B,C,D Correct answer
Explanation

During ejbPostCreate, the entity bean's identity is fully established, meaning getEJBObject() and getPrimaryKey() can be safely called. getEJBHome() and transaction methods like getRollbackOnly() are also accessible. However, getUserTransaction() is invalid because entity beans must use container-managed transactions (CMT) and cannot use bean-managed transactions.
