A,B Correct answer
Explanation

Session beans are categorized into exactly two types: stateless session beans (no conversational state maintained between calls, can be pooled) and stateful session beans (maintain client-specific state across method invocations). BMP (Bean-Managed Persistence) and CMP (Container-Managed Persistence) are persistence mechanisms for entity beans, not session bean types.

AI explanation

Session beans are divided into stateless (no conversational state retained between calls) and stateful (retain client-specific state across method invocations) types. BMP and CMP (bean-managed and container-managed persistence) are instead concepts related to entity beans, not session bean types.
