Cisco has announced CCNA v2.0! The switchover from v1.1 to v2.0 happens on February 3, 2027, so you still have 8 months to take v1.1 - plenty of time! You could start from 0 today and pass v1.1 in time, so DON'T PANIC! Give me some time to analyze the updated topics and think about it, and then I'll make some videos about v2.0 and my plans for it. I think it's a very good update, cutting out some of the more "painful" topics for CCNA students. The new topics focus heavily on configuration and troubleshooting.

I’m starting a new series documenting my journey to the CCIE: study plan, resources, mistakes, and lessons learned along the way. January update is live (it's a quick read): jeremysitlab.com/2026/02/02/… If you’re also studying (or already have your CCIE), I’d love to hear what helped you most!
