Massive in the particular field of technological solutions, Cisco is now a leader of it's industry-sector. It began with many more in the I.T. silicon-valley explosion of the early 80's, & has become the world-wide major networking hardware manufacturer. Each and every year Cisco's R and D expenditure alone comes to some $5 billion. Technological know-how from Cisco underpins the whole world wide web. Cisco supply over two-thirds of the network hardware used worldwide these days. For students thinking about working in IT or 'Telecoms' hardware-networking, 'Cisco' know-how is vital. 'Cisco' also has various trading arms that necessarily penetrate the 'Security', VOIP (Voice Over IP) Communications & Wireless-Data (or Wi-Fi) sectors - as they gain more business relevance.

The CCNA examination (640/802) can be split up into its 2 component parts: The ICND1 (640/822), & the ICND2 (640-816). 'ICND' stands for Interconnecting Cisco Networking Devices, however the ICND1 examination is also referred to as 'CCENT' ('Cisco Certified Entry Networking Technician'). All these abbreviations don't help to simplify matters for the person getting into I.T., however the most simple piece of advice is normally to think about the 'CCNA' 640/802 as a combined accreditation. 'Cisco' trainees will find it tremendously beneficial to start off their training course with the CompTIA accreditations 'A+' & N+ . That will provide them with extremely good vendor neutral training ahead of getting in to the 'Cisco' arena itself. You'll want to allow approximately 400 to 500 hrs of study-time for a combined course such as this. Technical IT training courses should always provide you with good professional support. Be sure to opt for one with 24 hour, immediate response service. The proper studying materials are essential - look for inter-active multimedia disc based programs, & an approved and reliable exam preparation system.

A lot of students elect to team up the A+, Network+ & 'CCNA' path with the Microsoft 'MCSA' or 'MCSE', for a much more rounded network education. Either way, a conversation about your career path and learning style, with a skilled IT professional or consultant, should be at the front of your list of priorities, to guarantee you will get off to a really good start & escape any expensive blunders.

The dilemma of exactly how to reproduce a Cisco environment to practise for examinations is frequently over-looked. Microsoft trainees preparing to take their 'MCSE' as an example can network a number of old PC's in their own home to practice on. This simply isn't do-able in a 'Cisco' environment, since you'd need enterprise class routers and data switches, as well as a substantial group of computers & various other highly expensive technologies. Cisco-approved 'visualisers' & network simulation-programs are the one and only practical option. These supply an on-screen software system, that will let you effectively develop large scale virtual-networks & test them, right down to particular router & data switch designs, together with being able to 'interrogate' the packages of information as they move through the network. Any self paced home based 'Cisco' training program needs to incorporate one of these extraordinary items of software. The highly reputed RouterSim's 'CCNA' Network Visualiser is undoubtedly one of the best we have tested, & we combine this in all our 'CCNA' programs.

To provide networking professionals with all the knowledge they need to work in this area, 'Cisco' offer a large number of training routes & certifications. Typically though, nearly all students will begin at one point, before they move upwards along the increasingly challenging variety of Cisco certification. The Cisco CCNA (Cisco Certified Network Associate) program contains 2 examinations, which will prepare an appropriate starting applicant with the essential skill in installation, configuration, operation, and trouble-shooting of medium-sized enterprise-level router and switched networks.

After the 'CCNA', qualification routes are quite diverse and may perhaps include a specialisation in Security or Wireless areas, or you might look at progressing to the CCNP (Cisco Certified Networking Professional.) The CCNP really is a relatively significant step up from the 'CCNA', & on the whole, contemplating this before you've wholly completed the CCNA is not a good idea. Gain the 'CCNA' & work with 'Cisco' networks for a year or two prior to moving on to any kind of CCNP training program. Really the only exception could be if you have a number of years of network practical experience built up and have dealt with much of the same ground as the CCNA qualification. Fundamentally employers will demand that anybody with very advanced accreditations has also had the right level of working hands-on experience to match them.
