So, what is a Cisco Certified Specialist credential? How do you get one? Why do you need one?

That alone is pretty cool, but it gets better. NetSim uses its Virtual Packet Technology® engine to create individual packets that are routed and switched through the simulated network, to build an appropriate virtual routing table and to simulate true networking.
