JGuru quizz errors and server failure

I just took the jguru EJB quizz on SUN website and I wonder if anyone else has
problems with a couple of the answers they provide.

7. What interface must the enterprise bean implement so that an application
can invoke its operations?   A is incorrect  Answer (C): javax.ejb.EJBObject

Hmmm, I thought the only interfaces IMPLEMENTED by the enterprise beans were
javax.ejb.EnterpriseBean type interfaces.  I thought EJBObject was SPECIFIED 
by the enterprise bean and implemented in an EJB container specific glue 
class.  I think I answered javax.ejb.SessionBean since it is implemented by 
the bean and  without it, the container cannot forward calls to the bean i.e. 
applications cannot invoke its operations.

10. What is a deployment descriptor?   C is incorrect  Answer (A):  An XML
file format used by the container to learn about the attributes of a bean,
such as transactional characteristics and access control

Hmm, I chose  A that said "An XML file used by the container  to learn about 
the attributes of a bean, such as transactional  characteristics and access 
control"  As far as I know deployment descriptors  exists as actual XML 
files, whose structure is specified by the DTD in the  EJB specification. I 
would ahe thought that the DTD, if anything, would be  the format.  I think 
this answer is plain wrong.

And, when I tried to submit my seedback to the Sun website, I got this 
 error:

Server Error
This server has encountered an internal error which prevents it from
fulfilling your request. The most likely cause is a misconfiguration. Please
ask the administrator to look for messages in the server's error log.

I think that pretty much speaks for itself.
