Network Fundamentals – Design & Build Enterprise Networks

Network Fundamentals – Design & Build Enterprise Networks

“Design and Build Enterprise Network” is a training about network fundamentals along with designing and building enterprise networks using the lab environment having newest network technologies and products. This course presents network fundamentals, real live project examples, photos of well made server rooms (along with badly designed server rooms), techniques for designing, implementing and troubleshooting IP networks.

Introduction to IP Networks

  • IT World Challenges – Introduction
