studies

My wife managed to keep the kids out of the bedroom long enough for me to get through the IPv6, IS-IS, and Route Map/VLSM/NAT videos from Trainsignal yesterday. I still don’t understand how I did so poorly on the IS-IS section of the BSCI exam two weeks ago. I knew EVERYTHING covered in that video.

I learned some stuff in the IPv6 video that I didn’t know, but I’m still a bit foggy on the 6to4 tunneling. I am going to go back through the authorized self study chapter on IPv6 tonight and see if I can solidify that topic for myself. If I can make it through the multicast sections today/tomorrow and redistribution by Tuesday, then I am going to try and schedule my re-take of the exam for late this week. If not, I’m going to give myself next weekend and take the exam next Monday.

I’m disappointed. I REALLY wanted to be well on my way to knocking BCMSN out of the way by now. I guess I’m just going to have to push harder to get this stuff done.

quick update

I haven’t done a bit of studying since I failed that exam a week ago. I wanted to jump right back on the horse, this week, and get to studying my weak points (IPv6, IS-IS, and multicast). My wife and both of my daughters came down with the flu last weekend, and I’ve been fighting it all week. On top of that, I’ve been dealing with bursitis and cellulitis in my left arm/elbow.
We’ve also stepped up our effort to re-IP our entire corporate network, and made some changes to the WAN this week. Needless to say, there’s been a little too much going on to really focus on any studies. I was eligible to take the exam again yesterday. I will try to take it again in the next week or so.

I spent a good chunk of time last night into this morning messing around with dynamips on my work provided laptop. It’s a Pentium M 1.6Ghz machine with 1 gig RAM. I was trying to do labs using 2621XM as the platform, and I couldn’t get more than two routers loaded w/o crashing dynamips. I moved to 3640’s with two different IOS images this weekend (ip plus for BBR and FRSW, and Enterprise for the pod routers). So far, I’m able to get all routers fired up without spiking the processors. I started loading configs on the FRSW and the BBR’s this morning and the CPU spiked. We’ll see how the laptop handles full configs.
I know I have the rack here, but I don’t get a whole lot of time to dedicate to it, unfortunately. I’m almost at the point of selling it off just to buy a decent home PC/Mac and a laptop.

BSCI Exam

Well,

I wasn’t ready for the exam. I went in fairly confident, but slightly psyched out. I ran through all of the chapter summaries and Q&A in the exam guide last night, reading sections that I wasn’t sure on. I hit up my notes, and fired up some of the gear to double check some answers on questions that I was unsure of.

I ended up with a 777/1000 on the exam this morning. passing is 790. IPv6 (specifically 6to4 tunneling) and IS-IS really hurt me. I knew I was weak on IPv6, but I didn’t realize I was THAT weak. Oh well. I’ll go back through the self study guide, and watch the trainsignal videos on IPv6 and IS-IS this week, and attempt the exam again in a few weeks.
