Quite a few prospective IT certification candidates have an interest in Cisco's foundation program. This is no surprise as Cisco is a popular certification sponsor. No wonder there is quite a bit of attention paid to Cisco Certified Network Associate (CCNA). The Exam (#640-607) replaced 640-507 as the Cisco Certified Network Associate 2.0 exam in March 2002.
What is CCNA?
But what really is CCNA? CCNA is a beginning-level program that aims to certify a solid foundation in Cisco networking. Cisco's certification programs are about certifying the competence of Internetworking professionals in routing, switching and connectivity. CCNA requires passing only one written exam (#640-607). Once this certification has been obtained, it can be a stopping point, as you've become qualified in Routing and Switching (valid for three years), or can be a starting point for a Professional-level certification.
But it is important to know why you are getting certified. For instance, do you know that for CCNA, you must have a good background in networking? In fact it is meant for anyone involved in implementing or supporting networks. A CCNA professional should be able to manage simple networked and internetworked environments incorporating routers and switches. Do you have an interest in networks or Internetworking? Do you want to work in the networking field? How does CCNA fit into your career development plan?
So what does CCNA entail? There are 55 to 65 questions asked, and and a candidate has 90 minutes to answer them with a required passing score of at least 849. Possible scores range from 300 and 1,000).
How you prepare for CCNA depends largely on your current knowledge and
experience of networking. Certification preparation options include
instructor-led training, e-simulations, practical labs, practice tests,
study materials, etc.
If you have the funds and time, it is always advisable to include instructor-led training in your preparations.
Back to Basics
As a first step, let's go back to networking. You must be comfortable with the technical fundamentals of networking. Practical networking means being familiar with the basics of networking. Can you describe the functions of the OSI model and explain the basic differences between a hub, switch, router, and bridge?
Fundamental networking means being able to: 1) apply fundamental data
communications and network concepts, 2) identify different types of
networks and network topologies, 3) share resources such as printers
on a network, 4) install and configure Network components, 5) identify
the differences between types of networks, 6) install and configure
networks, and 7) troubleshoot network problems with proven techniques
that are efficient and effective
It is absolutely essential that you have a good foundation in the fundamentals of networking.

DISRUPT THE STATUS QUO!
Ideas are not enough. You must be action oriented to improve your future.
Don't just think but act. You get results not only from thinking but from acting.
You have ideas. You want to achieve. You want opportunity.
But what are you still doing in your comfort zone? The comfort zone is a dangerous place.
"I wanted to", "I was going to" cannot put on a light bulb, not to talk of moving you forward.
Aren't you tired of hoping and criticizing? Stop defending status quo that locks you down.
GO on the offensive now with IT Education and Empowerment.
What is the use of ideas without action?
Start becoming the achiever you deserve to be.
MAKE SURE THERE IS NO STANDING ROOM FOR EXCUSES.
