For this web service exam, you may need to know the fact that each method invocation of a stateless bean is independent of each other.
For example, if you have an instance variable and one method invocation sets a value to it.
The next method invocation may not get the same value because this second method invocation may be invoked on a different stateless bean in the bean pool.
Yes, you must have a basic understanding of EJBs to include security and deployment. You must know the particulars of JAX-RS and JAX-WS as implemented as EJBs.
Not in-depth, but you need to know. Also, see my thread on why I failed. Don't neglet rote "wikitrivia" memorization on the topics. If it's a webservice topic and is described using a bulleted list (memorize the darn list).

I highly recommend you to use Ethuware mock exams and EPractice mock exams. They are helpful.
Also, try to get some mock exams from MZ. Send MZ a email to request for his mock exams.
Last but not least, try to google some free mock exams.
Practice is a must.
