Much like Microsoft, 'Cisco' leads the path as one of the world's most well known engineering technology companies. It started with many others in the IT Silicon Valley explosion of the 1980's, & has become the world's principal networking hardware manufacturer. Every year Cisco's R & D investment alone reaches some five billion dollars. Engineering technology from Cisco supports the entire net. Cisco produce more than two-thirds of the network hardware used worldwide these days. Not surprisingly therefore, anyone planning to develop a career path related to networking-hardware should preferably refer to 'Cisco'. The company also has developed commercially in more recent technologies like Voice Over IP (or VOIP), Security and Wireless-Data transfer.

One area that can be often over-looked with studying for 'Cisco' exams is how to reproduce the Cisco environment. If you're studying your MS MCSE or MCSA for instance, some old Computers are able to be 'networked' together to permit economical practice at home using real devices. This isn't the case with Cisco - to formulate any sort of practical environment you would need sophisticated routers & hardware, in addition to a large number of PC's and more extremely costly technologies. What you need therefore is to utilise Cisco approved network simulators & visualisers. Such hi tech software-systems enable students to make large networks in a virtual environment , using on-screen facilities to select specific hard-ware models and practice interrogation of data-movement. These really are outstanding bits of software, & no home-study or self-learning CCNA package should be without one. The hugely respected RouterSim's 'CCNA' Network-Visualiser is without doubt one of the best we've tested, & we include this in all of our 'CCNA' programs.

There are a number of qualification routes to go on to after finishing your CCNA. Specialized areas like security, or Wi-Fi may very well be selected, or maybe the CCNP ('Cisco Certified Networking Professional' ) which is more complex. It isn't advisable to think about taking the CCNP before you've totally finished your CCNA. Get the CCNA & get a job with 'Cisco' networks for a year or two ahead of progressing on to any 'CCNP' training program. The only real exemption from this could be if you have a number of years of networking practical experience already & have dealt with a lot of the same detail as the 'CCNA' accreditation. In essence, if you are starting up in it, no boss will expect you to have got to that level of accreditation, and may rightly query your exact comprehension, if you haven't even been employed in a CCNA job first.

The CCNA examination (640-802) can be broken down in to it's 2 component parts: The ICND1 (640/822), and the 'ICND2' (640/816). ICND is short for Interconnecting Cisco Networking Devices, although the 'ICND1' examination is also referred to as CCENT (Cisco Certified Entry Networking Technician). This may appear highly confusing, yet basically the qualification is better when tackled as a combined examination - the CCNA 640-802. 'Cisco' trainees should find it very beneficial to begin their training with the CompTIA qualifications A+ & 'Network+' . That will give them extremely good vendor-neutral preparation ahead of entering in to the 'Cisco' domain itself. Expect to put in approximately 400 to 500 hrs of study (approx a year part time) to complete a course of this type. In common with all 'technical' career training-programs, be sure to pick one that offers twenty four hour real-time access to tutor support, to 'problem-solve' any kind of learning issues that come up. The appropriate studying materials are crucial - go for interactive multimedia disc based products, & an accredited & effective exam preparation system.
