Much like MS, Cisco leads the path amongst the world's largest engineering technology businesses. From its humble inception around twenty six years back, 'Cisco' now invests something like $5 billion on research & development, and heads the world in networking-hardware. Society quite simply wouldn't have the world wide web we have today if it weren't for 'Cisco'. 'Cisco' provide over 2/3rds of the network hardware used around the world at this time. This instantly puts Cisco at the front of the list for students aiming to develop a career in I.T. & Telecommunications hardware networking. Within the Cisco 'umbrella' there also are sectors in Wireless Data & Communications-Data, Voice over IP and Security.

No surprise then that a substantial amount of qualification programs have been developed by 'Cisco' to cover the multitude of patents & technologies it produces. Individuals tend to be encouraged to begin with the same qualification program, and then branch into specialised areas as they progress. Presently there are 2 examinations in the 'Cisco Certified Network Associate', or CCNA for short. These will furnish students who are suitable with the requested technical expertise to work with medium-sized networks with 'routers' & data switches.

A lot of trainees opt to team up the 'A+', Network+ & CCNA path with the Microsoft MCSA or MCSE, for a more 'rounded' network education. You should always talk over your training needs with an IT training expert before deciding on your way forward - it will not only save you money & time, it will double check that you're on the appropriate track from the start.

The two exams are 640-802, & they are broken down as follows - The 'CCENT' (Cisco Certified Entry Networking Technician) examination - often known as the ICND1 ('Interconnecting Cisco Networking Devices Part 1' - 640/822) exam, and the ICND2 (640-816) examination. While all this may seem like a mouth full (as often seems the case with I.T. abbreviations,) the easiest way to do this qualification is as a grouped together CCNA (640-802) examination. An excellent career training track for 'Cisco' students would be a blended program beginning with CompTIA A+ , followed by CompTIA 'Network+' and then the rather more specialised 'Cisco' 'CCNA'. You'll want to allow around 400 to 500 hrs of study time for a combined course such as this. As with all specialist study programs, 24-hour direct-access student support should be offered to let you learn and ask questions anytime you need to. Add-in comprehensive multi-media tutorial training, and an effective exam-preparation program & you will be set for great success.

Cisco's main interest is in 'routers', controllers & data switches. If we didn't have these types of tools, data wouldn't be able to move around networking systems. Computers need an operating-system to communicate within their network, but in addition to that the actual hardware has its very own system that has to be installed and maintained. Trouble shooting, on-going re-programming & re-configuration is important to maintain the consistent running of an expanding network. With the switch towards complete system integration of voice & information in modern day corporate office buildings (not forgetting military and other circumstances), Cisco is at the height of all contemporary communications.

The question of how to reproduce a Cisco 'environment' to practise for examinations can often be over-looked. When you're working on a MS 'MSCE' or 'MCSA' as an example, a couple of old Computers are able to be 'networked' with each other to permit affordable practice at home with genuine devices. To build a practise Cisco environment though would be really costly, as you would really need to assemble a large number of PCs, with Commercial technologies and 'enterprise-class' routers and switches. Cisco approved 'visualisers' & network simulation-programs are the only practicable solution. These provide an on-screen software system, that allows you to effectively develop large-scale 'virtual' networks & test them, all the way down to specific router & data switch types, together with having the ability to interrogate the packages of information whilst they traverse the network. Any self-paced home based 'Cisco' training course should include one of these extraordinary items of software. Among the highest quality software systems out there is the 'RouterSim' 'CCNA' Network Visualiser. Upon assessing this and a number of others, we're very pleased to include it in all our Cisco training paths.
