In EJB 2.x we could use the Service locator to cache Home interfaces (using jndi name as key). In EJB 3.0 one looks up directly to the business interface, that is you work directly with the proxy (no need to call home.create()) and caching can be a bad thing.

So the only real caching benefit of SL in EJB 3.0 is the caching of InitialContext, but for the exam though should I also consider caching of remote references as a benefit as well?

You might take a look at the thread http://www.coderanch.com/t/156191/Architect-Certification-SCEA/certification/Obsolete-Design-Patterns-EJB-SCEA#761868
 
It is sorta covered in the JavaRanch Style Guide.
