Well.. I took the Network Essentials MCP exam from Microsoft just for a goof.. to see how it was. It was fairly simple. It doesn't go into networking with too great detail, but it's a nice starting point because it does include a fair amount on all the typical networking standards of today. The book also mentions a good deal about network hardware, and so.. as I said before, it is a nice starting point for general learning about networking. Good luck!
