Finally got this off my to-do list. Woot!
I somehow let my JNCIE-ER lapse into an inactive state a number of months back (whoops), but it's now active again upgraded to ENT!
It was a bit trickier than I expected, but mostly because there was more focus on subjects I wasn't expecting to be so heavy. If I took more time to read the AJEX and AJER student guides it wouldn't have been an issue.
A few questions had me guessing at the intent because of the wording, where it seems they were asking one thing that made sense, but if you carefully read word-for-word it seemed to suggest another thing that made a lot less sense. But on the other hand, I only had a few 30 minute naps in the 30some hours leading up to the exam, so maybe my comprehension engine decided to crash on me
