Not unlike 'Microsoft', 'Cisco' champions the path amongst the world's most significant technological know-how businesses. It began alongside many others in the I.T. Silicon Valley explosion of the early 80's, and is now the world-wide primary networking hardware manufacturer. Each year 'Cisco's' R & D expenditure on it's own comes to something like five billion dollars. We basically would not recognise the internet we've got today without 'Cisco'. The Cisco branding is deemed to be responsible for over 70 percent of all networking-hardware. This automatically places them at the front of the list for trainees seeking to build a career in IT & Telecoms hardware networking. 'Cisco' also owns a number of trading-arms which necessarily penetrate the Security, VOIP (Voice Over IP) Communications & Wireless-Data (Wi-Fi) areas - as they gain growing commercial importance.

The CCNA examination (640-802) can be split into it's 2 component parts: 'Interconnecting Cisco Networking Devices' Part 1 & Part 2, or 'ICND1' (640-822) & ICND2 (640-816). A different name for Part 1 is Cisco Certified Entry Networking Technician or 'CCENT' for short. It might appear highly confusing, but in reality the accreditation is better when tackled as a packaged examination - the CCNA 640/802. Cisco students will find it extremely useful to start off their training with the 'CompTIA' accreditations A+ and Network+ . That will give them excellent vendor-neutral preparation ahead of getting into the 'Cisco' arena itself. A bundled training-package of this nature would take about twelve months to achieve if training part time. Technical I.T. training programs should always provide solid qualified support. You should opt for one with 24 hour, immediate reply provision. The proper studying materials are vital - go for interactive multi-media disc based products, and an approved and highly effective exam prep system.

Cisco's primary business is in routers, controllers & data-switches. Data can flow through a 'network ' because of these Cisco solutions. PC's need an 'operating system' to communicate inside their 'network ', but in addition to that the actual hardware has its own system which has to be set up & maintained. Business networks must efficiently & regularly have to increase, consequently on-going maintenance means technicians must trouble-shoot, reconfigure & reprogram on a regular basis. 'Cisco' is at the heart of just about all current office communications (business and government) as we watch the worldwide move towards complete voice & information systems-integration.

There are a number of accreditation paths to progress onto after completing your 'CCNA'. Specialist sectors that include Security, or Wi-Fi could be thought about, or maybe the 'CCNP' ('Cisco Certified Networking Professional' ) which is rather more advanced. The step-up from the CCNA to 'CCNP' is quite big, so it's a good idea to focus on finishing your CCNA initially. You would expect to be working in a 'Cisco' environment for not less than 12 to 24 months (with your CCNA certification) before you started to study for your CCNP. However if you've actually been in I.T. for some time, & perhaps acquired a qualification that compares to the 'CCNA' (e.g. during military service) you may be able to go straight to CCNP. The bottom line is that if you are starting in it, no recruiter will be expecting you to be at such a high level of qualification, and may rightly question your real comprehension, if you've not even worked in a 'CCNA' role first.

Many students choose to team up the 'A+', N+ & 'CCNA' track with either the MS 'MCSA' or 'MCSE', for a much more 'rounded' networking education. In either case, a discussion of your career path and learning-style, with a seasoned IT professional or advisor, really should be at the top of your sheet of priorities, to ensure you will get off to the best possible start & avoid any expensive errors.

Effective practice for 'Cisco' exams can be a weak area for several training providers. If you're rehearsing for a MS examination, you can assemble a few old PCs and have a proper networked system to learn with. This isn't the case with Cisco - to create any sort of practical environment you'd need complex routers and hardware, in addition to many computers and further really expensive technologies. Cisco-authorised 'visualisers' and network simulation-programs are the one and only practicable answer. Allowing you to practice 'on-screen', these types of software-systems provide you with the ability to construct & test virtual networks. You 'work' with specific routers and data switches, and may even interrogate information as it traverses through the network system. A software program such as this is what splits training-programs apart - it is not a good idea to contemplate any Cisco package which doesn't feature it. The hugely reputed RouterSim's 'CCNA' Network Visualiser is without doubt one of the most effective we have tried, and we combine it in all our 'CCNA' courses.
