Cisco IOS Quick Reference Cheat Sheet 2.0 [ MrCambron ]

This document is restored from some notes I took while studying for CompTIA A+ and Cisco CCNA certifications when I was enrolled in Columbia Basin Job Corps from Feb 2007 to Jan 2009.

My original goal of this document was to fit this on one sheet of paper by changing to landscape view and printing two pages per side with the duplex option.
