Massive in the world of technological know-how, Cisco has become a leader of it's industry-sector. It started out together with many others in the I.T. silicon-valley revolution of the early 80's, and has become the world's major networking-hardware producer. Every year Cisco's R and D investment on it's own reaches something like five billion dollars. Engineering technology from Cisco underpins the entire web. It is predicted that over 70 percent of all worldwide network hardware is represented by the Cisco brand name. This automatically puts Cisco at the front of the checklist for individuals aiming to build a professional career in IT and Telecommunications hardware networking. Within the 'Cisco' 'umbrella' there are also sectors in Wireless Data and Communications Data, VOIP and Security.

There is a range of qualification tracks to move onto after completing the 'CCNA'. Specialist fields that include Security, or Wi-Fi might be thought about, or perhaps the 'CCNP' ('Cisco Certified Networking Professional' ) which is rather more advanced. It isn't a good idea to think about doing the 'CCNP' until you have totally finished your 'CCNA'. Get your 'CCNA' & start working on Cisco networks for a year or two ahead of progressing on to a 'CCNP' training program. There are some exceptions to this advice, particularly if you've worked in the industry for a while, and possess alternative accreditation that covered much of similar skill-base (military exams for example.) Essentially recruiters need to be sure that a candidate with rather senior accreditations has also had the right amount of practical hands-on experience to match them.

There are two constituent segments to the 640/802 CCNA accreditation: The 'ICND1' (640-822), and the ICND2 (640-816). ICND represents 'Interconnecting Cisco Networking Devices', although the 'ICND1' exam is also referred to as 'CCENT' ('Cisco Certified Entry Networking Technician'). This might seem very baffling, but in essence the certification is best taken as a blended examination - the CCNA 640/802. An outstanding career training-track for 'Cisco' students would be a blended program starting with 'CompTIA A+' , then CompTIA N+ and then the more advanced Cisco 'CCNA'. You'll want to allow yourself around four to five hundred hours of study time for a combined program like this. Much like just about all technical training programs, 24-hour direct access student support needs to be accessible to let you learn and ask questions anytime the need occurs. Check also for some of the latest multi-media study materials, & the right exam preparation software.

Proper practice for 'Cisco' exams is often a weak spot for some training providers. When you're practicing for a Microsoft examination, you can assemble a few old PC's and you have a proper networked system to play with. This is not possible in a Cisco environment, as you'd need enterprise-class routers and hardware, as well as a substantial cluster of PCs and various other extremely costly technologies. The solution then is to use Cisco-approved network simulators & visualisers. These hi tech software systems permit trainees to build large 'networks' in a virtual-environment , with on-screen options to select specific hard-ware models & practise 'interrogation' of data-movement. These are superb pieces of software, & no home-study or self learning 'CCNA' package should be without one. One of the highest quality software systems on the market is the RouterSim CCNA Network Visualiser. After testing this and a number of others, we are happy to feature it in all of our 'Cisco' training-paths.

Cisco's primary interest is in routers, controllers & data-switches. If we didn't have these systems, data wouldn't be able to 'flow' around networks. Whilst an Operating-System is necessary on a PC for it to connect throughout a 'network ', the actual network hardware itself has its own language and protocols that must be set up, maintained and configured. For a 'network ' to run smoothly there has to be on-going trouble shooting, with regular reprogramming and reconfiguring. In every area of modern day communications, 'Cisco' is playing a fundamental role. This is to a large degree due to the shift towards full system-integration of voice and information both in commercial and public workplaces.

Little wonder then that a great amount of accreditation paths have been developed by 'Cisco' to handle the assortment of patents and technologies it provides. To make things simple, candidates are likely to be advised to begin their Cisco training programs at the exact same stage, before developing more senior and specialised skillsets. And so the CCNA - or 'Cisco Certified Network Associate' will prepare the right individuals for professional work on small to medium router and data-switched networks, providing them knowledge of how to install, configure, operate & how to trouble-shoot.

Lots of students opt to partner the A+, N+ & 'CCNA' path with either the Microsoft 'MCSA' or MCSE, for a rather more rounded network knowledge structure. You should always talk about your training needs with an industry specialist before concluding your options - it will not only save you money & time, but it will make sure that you are on the ideal course from day one.
