I want to do a self study CCNA course but i only have 2 years MCSE experience, do you think i will manage with the content or will i have to setup a lab and continually work with it, esp the SemSim or router simulation stuff or what you guys recommend? and i want to get a good self study guide, and advice in this department, and im not too jacked up on network, im running a lil 40 pc network now, with an ISA server, and DC, DNS, DHCP,Acronis RIS, on the other, and i had some difficulty setting up the ISA but really enjoyed it, how is CCNA in comparison to ISA, because i took to the ISA quite easily, i want to know in regard to difficulty here, thanks in advance
