I dont know about that particular course, but I've taken SA-238 and SA-288(Solaris Sysadmin I&II), and while there's no "included" test, there is a test where those courses are the preq's, and from what I've heard, it's not something you should try until you've had quite a bit of time to make practical use of the stuff you learned at the courses.
In other words it's real hard.
Dont know if the exam you're referring to is as hard or not, but...   well there you go 
 
Oh and yes, those courses are expensive as hell, the Sysadmin I&II came with a packet price of a low low $3.7K.
