A giant within the particular field of technology, Cisco is now a leader of its industry sector. It started alongside many others in the IT Silicon Valley explosion of the early 80's, and has become the world-wide major networking-hardware developer. Each year Cisco's R & D outlay on it's own amounts to some five billion dollars. Engineering technology from 'Cisco' underpins the entire web. Cisco provide over 2/3rds of the network hardware employed in our world right now. For individuals thinking about working in I.T. or 'Telecoms' hardware-networking, 'Cisco' know-how is paramount. Cisco also has a number of trading-arms which automatically penetrate the Security, Voice Over IP (VOIP) Communications and Wireless Data (Wi-Fi) sectors - as they gain growing commercial importance.

To get a particularly well-rounded networking career-path, you might consider including either the Microsoft 'MCSE' or 'MCSA' to your 'A+', Network+ and CCNA program. With so many alternatives out there, a career track like this should always be discussed with an IT experienced professional. That way you can be sure that nothing unsuited to your requirements has been added, & nothing is missed out.

The two exams are 640-802, & they are divided as follows - The 'ICND1' (640/822), & the ICND2 (640-816). 'ICND' is short for 'Interconnecting Cisco Networking Devices', although the 'ICND1' examination is also referred to as 'CCENT' ('Cisco Certified Entry Networking Technician'). Although all of this can appear to be a mouth full (as often seems the case with I.T. acronyms,) the easiest way to do this accreditation is as a combined CCNA (640/802) exam. An outstanding career training track for Cisco entrants would be a blended package beginning with CompTIA A+ , followed by CompTIA N+ and then the more specialised 'Cisco' 'CCNA'. You should allow roughly 400 to 500 hrs of study time for a combined course such as this. Technical I.T. training programs should offer you sound professional support. You should select one with round-the clock, instant response provision. Add in all-inclusive multimedia tutorial training, and an effective exam-preparation system & you'll be set for success.

'Cisco's' principal interest is in 'routers', 'controllers' & data-switches. Without these types of devices, information would be unable to move around networking systems. Computers require an operating system to communicate inside their 'network ', but in addition to that the hardware has its very own 'system' which has to be installed and maintained. All networks must run smoothly & regularly have to expand, therefore on-going maintenance programs mean technicians need to trouble shoot, re-configure and reprogram on a regular basis. With the move towards complete system-integration of voice and information in today's business offices (in addition to military & other environments), Cisco has found itself at the peak of all contemporary communications.

One area that's often over-looked with studying for Cisco examinations is how to reproduce the Cisco environment. When you're rehearsing for a Microsoft exam, you can assemble a few old PC's & have a real networked system to experiment with. This isn't feasible in a 'Cisco' environment, since you would require enterprise class routers and switches, to say nothing of a significant group of computers and various other extremely expensive technologies. Really the only acceptable option is to use 'simulated' networks that are approved by 'Cisco'. These deliver an on-screen software-system, that permits you to effectively develop large-scale virtual-networks and test them, all the way down to precise router/data-switch types, as well as having the ability to 'interrogate' the packages of data whilst they move through the network. These really are exceptional bits of software, and no home-study or self learning CCNA package should be without one. The extremely well regarded 'RouterSim's' 'CCNA' Network-Visualiser is undoubtedly one of the most effective we have tried, & we include it in all of our CCNA training programs.

Little wonder then that a substantial number of qualification paths have been developed by Cisco to deal with the multitude of patents & technologies it produces. To simplify things, candidates are often advised to start their Cisco training at the same point, prior to acquiring more complex and specialist skill-sets. And so the CCNA - or Cisco Certified Network Associate will equip the right individuals for professional work with small-medium router & data-switched networks, providing them knowledge of installation, configuration, operation & how to trouble-shoot.

Following the 'CCNA', certification paths are quite varied and might include a specialization in Security or Wireless areas, or you could take a look at moving on to the CCNP (Cisco Certified Networking Professional.) The CCNP is really a fairly significant step-up from the 'CCNA', and for most people, thinking about this before you've wholly completed your CCNA isn't recommended. You'll want to get 2 yrs of Cisco experience along with your CCNA prior to progressing onto 'CCNP' certification. However if you've actually been in I.T. for a while, & have already achieved a certification that is equivalent to the 'CCNA' (e.g. during military service) you could possibly move straight to CCNP. In reality no employer will think of you for any senior position when you haven't got a fair degree of CCNA grade working-experience & understanding of networks.
