28. Which are guaranteed by EJB 2.0?

A) Server crashes will be transparent to entity bean clients.
B) Server crashes will be transparent to stateless session bean clients.

The correct answer is A, any one coule give me explanation.
Thanks a lot.

That one troubled me also. The bottom line is that following the specs, entity beans (pls note: not entity bean instances) will survive a container crash, because entity bean are a 'logical' representation of the underlying persistence storage (read db) and if your container crashes, your data don't, and because entity bean are on OO view of your data, they survive either.
