Linux System Admin and Network Management Training Manuals

Hello, I am selling two Linux training materials which I gently used during my Linux training not long ago. This training is straight from the Linux Foundation and so the material covered was very profound. The training was worth $3,000+, so for $20, the knowledge you will gain is so worth it. The manuals are clean with no pen or pencil markings. I took notes in a separate notebook. Please contact me if you are interested, thank you.
