## Lab 🧪

This lab is designed to have the engineer verify and execute their automation tools to interact with the
OS in a controlled fashion.

If you do the killercoda Lab 4, just answer these questions. If you are doing the lab in the ProLUG
environment, find the scripts in `/labs/automation/unit4`.

In the ProLUG lab, you must edit /root/hosts to point at your correct environment based on which “auto<x>”
server you have connected to.
