Renewing my JNCIP-ENT

Once you got the email from the vendor saying something like “Your certification is about to expire”, the only thing which come to my mind is “Dam it! Again…..”

So long story short, the exam is 120 minutes, 65 questions  and the same blueprint from last time. The only change i noticed was the Junos Software release, it is 15.1 now
I used my notes here from my previous studies.
There is another exam to achieve the JNCIP-ENT (JN0-646) which has the same blueprint but uses an Enhanced Layer 2 Software (ELS). The CLI it’s slightly on switching configs.

I got 73%, so it’s a pass! Maybe i get energy to face the JNCIE before i receive again the famous email “…about to expire”

I don’t remember the price of the JNCIP exam because i did it 3 years ago, but by the priced published by PearsonVue it increased apparently
