Cisco is amongst the biggest technology-companies on this planet, & just like MS, is a market-leader. It started with many others in the IT Silicon Valley revolution of the early 80's, and has now become the world's major networking hardware manufacturer. Every year Cisco's R and D expenditure on it's own amounts to something like $5b. We quite simply would not have the world wide web we've got today without Cisco. 'Cisco' supply over two-thirds of the network hardware used around the world today. This instantly places Cisco at the front of the checklist for individuals planning to develop a professional career in I.T. & Telecoms hardware networking. Within the 'Cisco' umbrella there also are sectors in 'Wi-Fi' & Communications Data, Voice over IP and Security.

To gain a really comprehensive network career-path, you could potentially look at including the Microsoft MCSE or MCSA to your A+, Network+ and CCNA program. Be sure to examine your career choices with a knowledgeable IT training expert prior to deciding on your options - not only will it save money and time, but it will also double check that you're on the ideal course from the beginning.

Controllers, 'routers' and data switches are essentially what Cisco engineering technology is founded on. These are the devices which facilitate the data that flows through a network. Just as an Operating-System is necessary in a computer for it to communicate throughout a network, the actual network hardware also has it's own language and standards that have to be set up, maintained & configured. For a network to run smoothly there must be constant trouble shooting, with frequent reprogramming & reconfiguring. In every area of modern-day communications, 'Cisco' is performing a fundamental part. This is in no small part due to the shift towards total system integration of voice and information both in commercial & public workplaces.

Following the CCNA, accreditation tracks are varied & could very well include a specialization in Security or Wireless fields, alternatively you could take a look at moving onto the 'CCNP' ('Cisco Certified Networking Professional'.) It isn't a good idea to consider taking the 'CCNP' until you've totally finished the 'CCNA'. You should expect to be operating in a 'Cisco' environment for not less than one or two years (having got your 'CCNA' qualification) before you started to train for the 'CCNP'. There are a few exceptions to this advice, especially if you've worked in IT for quite some time, & possess equivalent accreditation covering a lot of similar information (armed service exams as an example.) Essentially business employers will want to be sure that anybody with rather senior qualifications has had a suitable degree of working hands-on experience to go with them.

There are actually two component parts to the 640-802 'CCNA' certification: 'Interconnecting Cisco Networking Devices' Pt1 and Pt2, or 'ICND1' (640-822) and ICND2 (640-816). Another name for Part 1 is 'Cisco Certified Entry Networking Technician' or 'CCENT' if abbreviated. It might seem very difficult to understand, yet basically the accreditation is better when taken as a packaged exam - the CCNA 640/802. Cisco students should find it very useful to begin their training with the CompTIA qualifications A+ & 'Network+' . That will give them extremely good vendor neutral preparation ahead of getting in to the Cisco field itself. You'll want to allow about 400-500 hours of study for a blended program like this. In common with all 'technical' career training-programs, be sure you opt for one that gives 24/7 real time access to instructor support, to 'problem-solve' any training challenges that come up. Add-in all-inclusive multimedia tutorial materials, and a powerful exam-preparation program & you'll be set for success.

One area which is often overlooked when preparing for Cisco examinations is simply how to reproduce the 'Cisco' environment. MS students preparing for their MSCE for example can network a few old computers in their own home to practice on. To build a practise Cisco environment though would be extremely expensive, because you would need to put together many more PCs, with commercial technologies & 'enterprise-class' routers and switches. The only real practical option is to use 'simulated' networks that have been approved by Cisco. Such state of the art software systems permit students to build sizable networks within a 'virtual environment' , using on-screen facilities to pick specific hard-ware products and practise 'interrogation' of data-movement. A software package of this nature is exactly what sets training-programs apart - it's unwise to think about any 'Cisco' training which doesn't incorporate it. One of the very best software systems to choose from is the RouterSim 'CCNA' Network-Visualiser. After assessing this and a number of others, we're happy to include it in our 'Cisco' training paths.

It is hardly surprising then that Cisco offers an array of qualification tracks, dealing with all of its technologies and it's patents. To help make things simple, individuals are often encouraged to start their Cisco training programs at the exact same stage, prior to developing more complex and specialist skillsets. & therefore the CCNA - or Cisco Certified Network Associate will equip the right trainees for professional work on small-medium router and data-switched networks, providing them knowledge of installation, configuration, operation and how to trouble-shoot.
