I'm headed back to the exam center this afternoon for another shot at ONT. I feel a lot more prepared this time around thanks primarily to some practice with the MQC and also thanks to CBT Nuggets and Trainsignal videos. I'm still nervous, though. I really underestimated this exam the first time around and I'm really hoping that I'm not making the same mistake again. This morning I plan on reviewing the SDM interface, some wireless stuff, and CoPP. I feel like I have a good handle on DSCP and most of the VoIP and QoS topics. The main thing I think will have a chance on tripping me up are the questions that require you to be familiar with the GUI's for WLC's and WLSE and WCS. I never could find a way to get some hands-on time with those since my company doesn't use them.

Even more nerve-wracking, I have a job interview right before the exam!

I'll be sure to hop back on here and share my experiences, but hopefully the 2nd time will be the charm and I'll be 1/4 of the way towards my PNNC!
