Mock Question on Distributed Web App

[Alec Lee]

The javaranch.com shopping application was initially developed for a nondistributed environment. The company recently purchased the Supreme Application Server, which supports distributed HttpSession objects. When deploying the application to the server, the deployer marks it as distributable in the web application deployment descriptor to take advantage of this feature.
Given this scenario, which two must be true? (Choose two.)
A. The J2EE web container must support migration of objects that implement Serializable.
B. The J2EE web container must use the native JVM Serialization mechanism for distributing HttpSession objects.
C. As per the specification, the J2EE web container ensures that distributed HttpSession objects will be stored in a database.
D. Storing references to Enterprise JavaBeans components in the HttpSession object might NOT be supported by J2EE web containers.
