I got a lengthy email from one of my readers a while ago, essentially asking a simple question: assuming I want to go return to my studies and move further than CCIE I currently hold, should I go for CCDE or the new VMware’s VCIX-NV?
Well, it’s almost like “do you believe in scale-up or scale-out?” ;) Both approaches have their merits.
Aiming for CCDE is (oversimplifying to the extreme with sincere apologies to the CCDE community) going for more of the same, obviously replacing bit-by-bit protocol knowledge and configuration gimmicks with focus on network design and architecture.
Aiming for VCIX-NV is entering new territory – not entirely unfamiliar, it’s still routing and switching, but different.
We could discuss whether one or the other is a better career move (if you want to go down that tangent, write a comment), but if you want to pursue a certification to have a structured studying path (and force yourself to study – see also this post), you have to decide whether you love getting better at what you do (CCDE) or try something new (VCIX-NV).
