Which of the following are true? Select 2 correct options: (a) An EJB container must not allow same enterprise bean to be deployed multiple times. (b) EJB containers must allow remote IIOP invocations on the remote interfaces of session and entity beans. (c) EJB containers are required to be able to publish EJBHome object references in a CORBA CosNaming service. (d) EJB containers are not required to provide the implementation of the resource manager connection factory classes for the resource managers that are configured with the EJB Container. (e) EJB containers must allow all enterprise beans deployed using a single archive file to access each other directly without going through local or remote interfaces.
I am really confused in this question. What does it mean "deploy multiple times", "remote IIOP invocations ", "publish EJBHome object references"? And how about (d), and (e)?
