From a CCIE to you
I remember what it's like to be where you are.
I sat for my CCNA long before I had two CCIEs next to my name. I remember the pressure. The $300 exam fee I couldn't afford to waste. The 1,200-page textbook I tried to highlight my way through. The feeling of opening a chapter on OSPF and wondering if I was even smart enough for this career.
You are smart enough. The textbook is the problem, not you.
I wrote these guides because I run a managed-services provider, I'm on call for production networks, and every couple of months a new engineer joins our team needing the CCNA or CCNP. I write these guides the way I'd brief them — every CLI lab-tested, every concept distilled to what they need on exam day, every trap flagged in red. The cards I wish someone had handed me.
If a CLI snippet is in this guide, it's because I've typed it myself. If a memory hook is in this guide, it's because I've used it to explain a concept to a junior engineer who needed to get it fast. This is the playbook I'd hand my own team. It's the playbook I wish someone had handed me.
