Dude, week 3 has been a major letdown. I planned on knocking out objectives 4 and 5 in one week just like I did with objectives 2 and 3 last week. Week 3 has hit me hard because I've been incredibly busy with my full-time job and my job outside my professional life. So, I've only managed to barely get through objective 4 studying Zacker's book. I still have videos from TrainSignal to watch. My plan is to watch those this weekend.
Highlights of objective 4:
* New DHCP failover options: load-balancing and hot-standby. Very cool.
* Subnetting: always interesting.
* IPv6: another one of those always interesting topics.
