Not unlike 'Microsoft', 'Cisco' leads the path amongst the world's largest technology businesses. It started out alongside many others in the I.T. silicon-valley explosion of the early 80's, and has become the world's major networking-hardware producer. Each year 'Cisco's' research & development expenditure on it's own reaches some $5 billion. The internet, it's said, functions 'because' of 'Cisco' engineering. 'Cisco' provide more than 2/3rds of the network hardware employed around the world today. This automatically puts them at the top of the checklist for individuals looking to make a professional career in I.T. & Telecoms hardware-networking. 'Cisco' additionally has various trading-arms which necessarily permeate the 'Security', VOIP (Voice Over IP) Communications and Wireless Data (Wi-Fi) sectors - as they gain more commercial relevance.

It's not a revelation then that Cisco offers an array of qualification tracks, covering all of its various technologies and patents. Trainees tend to be recommended to begin with the same certification course, and then move into specialised areas as they develop. And therefore the 'CCNA' - or 'Cisco Certified Network Associate' will equip suitable trainees for professional work with small to medium router and switched networks, giving them knowledge of how to install, configure, operate and how to trouble shoot.

The 2 exams are 640/802, & they are split up as follows - The CCENT (Cisco Certified Entry Networking Technician) examination - also called the ICND1 ('Interconnecting Cisco Networking Devices Part 1' - 640-822) exam, & the ICND2 (640/816) exam. All these abbreviations do nothing to simplify matters for the student getting in to I.T., but the most straightforward piece of advice is generally to consider the 'CCNA' 640-802 as a combined qualification. An excellent career training-track for Cisco students would be a blended package starting with 'CompTIA A+' , then CompTIA N+ & then the more advanced Cisco CCNA. Expect to put in close to four to five hundred hrs of study time (approx 12 months part time) to finish a program of this type. In common with all 'technical' career training courses, be sure to select one that delivers 24/7 real-time access to instructor assistance, to 'problem-solve' any kind of training challenges that occur. Add-in comprehensive multimedia tutorial training, and an effective exam-preparation program and you will be set for great success.

There are a variety of qualification paths to go on to after completing the 'CCNA'. Specialized sectors like Security, or Wi-Fi Technology could possibly be thought about, or maybe the 'CCNP' (Cisco Certified Networking Professional) which is rather more complex. It isn't a good idea to think about doing the CCNP before you have totally completed your 'CCNA'. You'd expect to be operating in a 'Cisco' environment for not less than one or two years (having got your 'CCNA' accreditation) prior to getting started to study for the 'CCNP'. There are actually a few exceptions to this advice, especially if you have worked in the industry for a while, and have alternative accreditation covering a lot of similar skill-base (armed service exams for example.) Essentially recruiters will demand that anybody with rather advanced qualifications has had a suitable degree of working hands-on experience to go with them.

One thing which is frequently over-looked with studying for 'Cisco' examinations is how to reproduce the 'Cisco' environment. If you are studying a MS MCSE or MCSA for example, a handful of old PC's are able to be networked with each other to permit affordable practice in your own home using real equipment. Not so with Cisco - to formulate any sort of practical environment you would have to have complex routers and switches, in addition to many PCs & more really costly technology. Cisco authorised 'visualisers' and network simulation-programs are the only practical answer. Such hi tech software-systems allow trainees to make sizable networks in a 'virtual environment' , using on-screen facilities to pick particular hardware products & practise 'interrogation' of data-movement. Any self-paced home learning 'Cisco' training program must incorporate one of these extraordinary pieces of software. The hugely respected 'RouterSim's' CCNA Network Visualiser is undoubtedly one of the best we've tested, and we include it in all of our 'CCNA' training courses.

'Cisco's' primary business is in 'routers', controllers & data switches. Data can flow through a network as a result of these 'Cisco' solutions. Whilst an Operating System is required in a computer so that it can connect throughout a network, the actual network hardware also has it's own language and standards that must be set up, configured and maintained. For a 'network ' to run smoothly there must be on-going trouble-shooting, with regular re-programming and re-configuring. In every area of modern communications, 'Cisco' is playing a fundamental part. This is to a large degree because of the change towards total system integration of voice and information in both commercial & public places of work.
