Massive in the particular field of technological solutions, 'Cisco' has become the frontrunner of its industry-sector. Initially set up in the early 1980's, early on in the silicon-valley IT explosion, 'Cisco' has become the worldwide front-runner in networking hardware, investing around 5 Billion Dollars a year on R & D. The internet, its said, functions 'because' of Cisco engineering. It is estimated that over 70 percent of the entire global network hardware is represented by the 'Cisco' brand name. This instantly puts Cisco at the front of the list for trainees planning to build a professional career in I.T. and Telecoms hardware networking. Beneath the Cisco 'umbrella' there are also sections in Wi-Fi & Communications-Data, VOIP & 'Security'.

Following on from the 'CCNA', qualification routes are quite diverse & might incorporate a specialisation in Security or Wireless areas, or you could take a look at progressing on to the 'CCNP' (Cisco Certified Networking Professional.) It's not a good idea to consider doing the CCNP until you have totally accomplished the CCNA. You should expect to be working in a 'Cisco' environment for about 12 to 24 months (together with your 'CCNA' qualification) before you started to study for the 'CCNP'. The only real exception could be when you have quite a few years of networking practical experience built up & have dealt with a lot of the same ground as the CCNA certification. The bottom line is that if you're starting off in it, no boss will be expecting you to have got to such a high level of certification, and may rightly question your exact comprehension, if you've not even been employed in a CCNA role first.

'controllers', 'routers' & switches are essentially what 'Cisco' engineering technology is based on. Data can move around a network because of these Cisco devices. Just as an Operating System is required on a computer for it to communicate throughout a network, the network hardware itself has it's own language & standards that need to be set-up, maintained and configured. Business networks need to efficiently & regularly have to expand, and so ongoing maintenance programs mean specialists must trouble shoot, re-configure and re-program on a regular basis. In every area of modern day communications, Cisco is enjoying a key part. This is in no small part because of the change towards full system-integration of voice and information in both private & government workplaces.

One area that can be frequently over-looked with studying for Cisco exams is exactly how to reproduce the 'Cisco' environment. If you are working on your Microsoft 'MCSA' or 'MCSE' for example, a couple of old PC's are able to be networked with each other to allow inexpensive practice in your own home using real equipment. To re-create a Cisco environment though would be incredibly costly, because you would really have to put together a large number of PC's, with Commercial technologies and enterprise class routers and switches. The only workable option is to use 'simulated' networks that are approved by Cisco. These provide an on-screen software-system, that enables you to effectively develop large-scale 'virtual' networks & test them, all the way down to specific router/data-switch types, along with having the ability to 'interrogate' the packets of information as they traverse the network. These are outstanding pieces of software, and no home study or self-learning 'CCNA' course should be without one. We have now incorporated 'RouterSim's' CCNA Network Visualiser in each of our CCNA career-tracks - this is a very well regarded 'simulator' & without any doubt among the best we tested.

To get a specifically well rounded networking career path, you could potentially consider adding the MS 'MCSE' or 'MCSA' to your A+, 'Network+' and 'CCNA' program. You should always speak about your training needs with an IT training specialist before settling on your way forward - it will not only save you time & money, it will also ensure that you're on the correct track from the start.
