Not unlike Microsoft, Cisco champions the way as one of the world's largest engineering technology organisations. Initially started in the early 1980's, early on in the Silicon Valley I.T. explosion, Cisco has become the worldwide leader in networking hardware, investing around five Billion dollars annually on research and development. The world wide web, it's said, succeeds 'because' of 'Cisco' technology. It's predicted that more than seventy per cent of all global network-hardware is represented by the 'Cisco' brand. Not surprisingly therefore, anyone seeking to build a career path to do with networking hardware is advised to focus on 'Cisco'. The business has additionally developed commercially in new technology systems such as Voice-Over IP (VOIP), 'Security' and Wireless-Data transfer.

The CCNA exam (640-802) is broken down into its two component parts: The CCENT ('Cisco Certified Entry Networking Technician') exam - also referred to as the 'ICND1' ('Interconnecting Cisco Networking Devices Part 1' - 640-822) exam, and the ICND2 (640/816) exam. This may appear very confusing, but essentially the accreditation is best taken as a combined examination - the 'CCNA' 640-802. This specific path would greatly gain from being partnered with the 'CompTIA A+' and CompTIA Network+ accreditations, since they will provide all of the important 'grounding' before attempting the more specialised Cisco-specific exams. A merged training package like this would take around twelve months to do if training part-time. As with all specialist study programs, 24/7 direct-access student-support needs to be offered to help you to learn and ask questions anytime the need occurs. The right learning materials are vital - go for inter-active multimedia disc-based programs, & an approved and highly effective exam practice system.

Sufficient preparation for Cisco exams can be a vulnerable thing for many training-providers. If you're studying a MS MCSE or MCSA as an example, a few old PC's can be networked with each other to allow economical 'dummy-runs' in your own home with real devices. To build a practise Cisco environment though would be extremely expensive, as you would need to set up a large number of PC's, with commercial technologies & 'enterprise-class' routers & hardware. Cisco-approved 'visualisers' and network simulation-programs are really the only workable answer. These provide an on-screen software-system, that enables you to effectively build large scale 'virtual networks' & test them, all the way down to specific router/data-switch versions, in addition to having the ability to interrogate the packets of information whilst they move through the network. Any self-paced home-based 'Cisco' training course must include one of these incredible pieces of software. The highly respected RouterSim's CCNA Network Visualiser is undoubtedly one of the best we have tried, & we include it in all of our CCNA programs.

There are a number of certification paths to go on to after finishing the 'CCNA'. Specialised areas that include security, or Wireless Technology could be selected, or perhaps the 'CCNP' ('Cisco Certified Networking Professional' ) which is rather more advanced. The step-up from the CCNA to the CCNP is pretty significant, so it is sensible to focus on completing the 'CCNA' first. You'd expect to be operating in a 'Cisco' environment for not less than a year or two (together with your CCNA qualification) prior to getting started to train for the CCNP. There can be a few exclusions to this advice, mainly if you've been in IT for a while, and have got equivalent accreditation covering much of similar information (armed forces examinations for instance.) Essentially business employers have to know that an individual with quite advanced qualifications has had an appropriate amount of practical experience to go with them.

Cisco's primary interest is in 'routers', controllers and data switches. They're the devices which control the information that flows all around a networking system. Networking-hardware has it's own list of rules and principles. The 'hardware' must be set up & configured properly. For a network to run smoothly there needs to be constant trouble-shooting, with regular re-programming & reconfiguring. In every area of modern day communications, Cisco is playing a fundamental part. This is in no small part due to the change towards total system-integration of voice & information in both commercial & government office buildings.

To furnish networking professionals with all the skills they must have to operate in this particular field, Cisco offer an array of training routes & certifications. Students are often encouraged to begin with the same certification program, and then progress into specialist elements as they advance. The Cisco CCNA (Cisco Certified Network Associate) training consists of two examinations, which will prepare the right entrant applicant with the essential skill in installation, configuration, operation, and trouble shooting of medium sized enterprise level router and switched networks.

Lots of students opt to partner the 'A+', N+ & CCNA path with the Microsoft 'MCSA' or MCSE, for a rather more rounded network education. Either way, a discussion of your career path and learning-style, with a seasoned IT expert or advisor, must be at the head of your sheet of priorities, in order to ensure that you get off to a great start and escape any expensive blunders.
