Yes Cisco is a good way to go. CCNA is the basics, but dont let that fool you in any way. It is still not that easy. It is completely different from N+ and those basic exams.
You will do things linke basic routing, configurations, vlans, Class A,B and C subnetting, etc...
The Exam is about 1 hour 30 mins and you have to do 5 simulations where you need to trouble shoot routing and vlans and all sort of things. With all that you still need to do 44 other quistions aswell. You also need 82.5% to pass.
If you do not have access to live Cisco equipment you will battle. I recently got the Packet Tracer 5 app from Cisco which seems to be able to do more than all the other simulators I have used. It is well worth buying it. GNS3 is an emulator which is the best because you use real IOS images from Cisco deviced but it is difficult to do a big simulation since it is very resource intensive.
