A giant in the field of technological solutions, Cisco has become a leader of its industry sector. It started out together with many others in the I.T. silicon-valley explosion of the 1980's, and has now become the worldwide principal networking hardware developer. Each year 'Cisco's' R and D outlay alone comes to some five billion dollars. Technological know-how from 'Cisco' underpins the whole world wide web. The 'Cisco' branding is understood to be accountable for over 70 percent of all networking hardware. This automatically places Cisco at the front of the checklist for trainees aiming to make a career in I.T. & Telecommunications hardware-networking. Beneath the 'Cisco' 'umbrella' there are sectors in 'Wi-Fi' and Communications-Data, VOIP & Security.

After the CCNA, accreditation paths are quite diverse and may perhaps incorporate a specialization in Security or Wireless areas, or you might take a look at progressing to the 'CCNP' ('Cisco Certified Networking Professional'.) It's not recommended to contemplate taking the 'CCNP' until you have totally finished your CCNA. Achieve your CCNA & work with 'Cisco' networks for 12 to 24 months ahead of progressing on to a CCNP study program. There are actually some exceptions to this, mainly if you have worked in IT for a while, and have got equivalent certification covering much of the same skill-base (armed service exams as an example.) The bottom-line is managers have to know that an individual with rather senior qualifications has had a suitable degree of working hands-on experience to match.

Many trainees opt to combine the 'A+', Network+ and 'CCNA' track with the MS MCSA or 'MCSE', for a rather more 'rounded' networking education. With so many options to select from, a career-path like this should invariably be discussed with an expert. That way you will be certain that nothing that conflicts with your needs has been added, and nothing has been overlooked.

The two exams are 640/802, and they are split as follows - Interconnecting Cisco Networking Devices Part-1 & Part-2, or 'ICND1' (640/822) and ICND2 (640-816). An alternative name for Part 1 is 'Cisco Certified Entry Networking Technician' or CCENT if abbreviated. Although all this may appear to be a mouth full (as often seems the case with I.T. abbreviations,) the most straightforward way to do this qualification is as a grouped together CCNA (640-802) exam. A very good career training-track for Cisco entrants would be a combined package beginning with 'CompTIA A+' , followed by CompTIA Network and then the more advanced Cisco CCNA. Expect to put in around four to five hundred hours of study (around 12 months part-time) to finish a program of this nature. In common with all technical career training-programs, make sure you pick one that delivers 24 hour real-time connection to tutor assistance, to 'problem-solve' any kind of studying issues that come up. The proper study materials are essential - look for interactive multimedia disc-based programs, and an approved & highly effective exam practice system.

To equip networking experts with all of the skills they need to operate in this particular field, 'Cisco' offer an array of training tracks and qualifications. Students are often recommended to begin with exactly the same qualification program, & then move into specialist subjects as they progress. & so the CCNA - or 'Cisco Certified Network Associate' will prepare suitable trainees for professional work with small to medium router & data-switched networks, providing them knowledge of how to install, configure, operate & how to trouble shoot.

Cisco's main business is in 'routers', 'controllers' and data-switches. They're the tools which control the information that flows through a networking system. Networking-hardware has it's very own set of rules and procedures. The 'hardware' needs to be set up & configured properly. For a network to run efficiently there must be on-going trouble shooting, with frequent reprogramming & reconfiguring. In every area of modern communications, 'Cisco' is performing a key part. This is to a large degree due to the change towards complete system integration of voice and information both in commercial & government office buildings.

One thing that is frequently over-looked with studying for Cisco examinations is exactly how to reproduce the Cisco environment. If you are studying the Microsoft 'MSCE' or 'MCSA' for instance, some old PC's can be networked with each other to allow economical 'dummy-runs' in your own home using real devices. This simply isn't do-able in a 'Cisco' environment, since you'd require enterprise-class routers & data switches, as well as a large group of PCs and various other very expensive technologies. Cisco-authorised visualisers and network simulation-programs are really the only workable way to do it. These provide an on-screen software-system, that enables you to effectively construct large-scale virtual-networks & test them, down to precise router/data-switch designs, as well as being able to interrogate the packages of information as they navigate the network. A software program of this standard is exactly what sets training-programs apart - it's not wise to decide upon any Cisco package that doesn't encompass it. One of the very best systems on the market is the RouterSim 'CCNA' Network Visualiser. As a result of testing this & several others, we are very pleased to feature it in our 'Cisco' training-paths.
