When talking about BMP we refer to entity beans exclusively since session and message-driven beans cannot be made persistent. At this point, you should note that the exam does not require you to know anything about BMP entity beans because they do not seem to be widely used anymore.

Moreover, section 17.3.1 states that whatever the persistency policy is, entity bean MUST NOT be designed with bean-managed transaction demarcation (BMT). This is a requirement!
