Currently, only the LCNS V6 is available.
LCNA v7 is also available, and the LCNA v7 is comparable in difficulty to the LCNS V6.
The LNCS V7 may be out next year.
Where do you get the questions? Officially, by writing the exam. The exam is based partially on the Legato 640 course. Other areas of study would be the NetWorker Admin guide. Also, the LCNS v6 and LCNA v7 is not o/s specific... i.e, the questions can be based on Windows, Solaris, HP-UX, etc... I remember there are questions on NDMP, cluster, and definitely performance questions.
I do not know where you can get a copy of any lcns questions. That wouldn't be legal, right?
