Network Automation Fundamentals
The core concepts behind how network automation actually works: inventory, state, idempotency, and safe failure handling.
This module names the handful of ideas that quietly underpin every automation task you'll ever write: the building blocks every script shares, why a device needs structured inventory instead of just a hostname list, and the difference between what a device is configured to do and what it's actually doing right now. You'll also work through idempotency -- why blindly reapplying configuration is dangerous at scale -- and how automation should report failure honestly instead of hiding it. None of this involves real code yet; it's the vocabulary and judgment you'll rely on starting in the very next module, when Python and real device connections enter the picture.
