Is it just me? or is the CCSA confusing as hell?

I don't understand the NGX addition to 156.215.1. We run r70.40 code on our firewalls, so I guess I'll chase the 156.215.71 exam, as it's the most current.

I was confused when I saw this .1 version though. From the outline, it seems that the only real difference between it and the .70 and .71 is the inclusion of NGX. Am I right?

Thanks,
Mike
