Message Driven Bean mimicks structure of Session bean in some manner.

Message Driven Beans (MDBs) share structural similarities with Session Beans. The answer is True because MDBs follow the same lifecycle callback pattern (ejbCreate, ejbRemove) as session beans, and they're also managed by the container. The key difference is MDBs don't have a client-visible interface - they respond to JMS messages instead of direct client calls. But structurally, they mimic session bean patterns for lifecycle management.
