Well what with my recent success in exams, I decided its about time i sat my CCNA. I was working with Cisco routers and switches for about two years in the last place and it really would be a waste of knowledge not to sit this exam before I forget it all.
Man I didn’t realise how much i had forgotten until i managed to get my hands on a copy of packet tracer! Packet tracer is like a work bench where you can setup virtual servers, clients, printers switches routers… even wireless routers and test connectivity between the devices. The icing on the cake no less, is that you have an individual IOS and and terminal session on each device mimicking near exactly the actual routers connectivity.
On a side note, who ever invented sub-netting, bit pinching and network address shortening… I’d kick you in the face for making me do maths.
