A giant within the subject of technological know-how, 'Cisco' is now the frontrunner of it's industry-sector. It started with many others in the IT silicon-valley revolution of the early 80's, and has now become the worldwide major networking-hardware producer. Each and every year Cisco's research & development investment on it's own comes to something like $5 billion. We quite simply wouldn't recognise the web we have today without 'Cisco'. The Cisco brand is thought to be responsible for above 70 percent of all networking hardware. Not surprisingly therefore, anyone hoping to build a career to do with networking-hardware should consider Cisco. Within the Cisco 'umbrella' there are also divisions in 'Wi-Fi' and Communications-Data, Voice over IP and 'Security'.

To equip networking experts with all of the information they need to perform in this area, Cisco provide an array of training programs & qualifications. Individuals are often advised to begin with exactly the same qualification program, & then move into specialised subjects as they progress. There are two exams for the 'Cisco Certified Network Associate', or 'CCNA' for short. These will furnish trainees who are suitable with the recommended technical know-how to control medium-sized networks with routers & data-switches.

The question of how to reproduce a Cisco 'environment' to practise for examinations is frequently not addressed. When you're working on the Microsoft 'MSCE' or 'MCSA' as an example, a handful of old Computers are able to be 'networked' with each other to allow affordable practice in your own home using real equipment. This isn't the case with 'Cisco' - to create any kind of effective environment you'd need complex routers and data switches, in addition to many computers and more very high priced technologies. What you need therefore is to use Cisco-approved network simulators & visualisers. These supply an on screen software system, that will let you effectively build large-scale virtual-networks and test them, down to precise router/data-switch designs, along with having the ability to 'interrogate' the packages of data whilst they move through the network. These really are exceptional bits of software, & no home study or self-learning CCNA training program should be considered without one. We have now included RouterSim's CCNA Network Visualiser in each of our 'CCNA' career tracks - this is a very highly regarded 'simulator' & undoubtedly one of the highest quality products we tried out.

There are a variety of accreditation tracks to move onto after completing your 'CCNA'. Specialized fields such as 'Security', or Wi-Fi might be looked into, or perhaps the CCNP ('Cisco Certified Networking Professional' ) which is rather more advanced. It's not recommended to think about doing the CCNP before you've entirely finished your CCNA. Achieve your 'CCNA' & work with Cisco networks for one or two years prior to progressing onto any kind of 'CCNP' training program. If however you have actually been in the industry for quite a while, & maybe acquired a accreditation that compares to a CCNA (for instance whilst in the military) you could possibly go directly onto 'CCNP'. Fundamentally recruiters will demand that a candidate with rather senior qualifications has also had the right level of practical hands-on experience to go with it.

There are actually 2 constituent elements to the 640-802 'CCNA' qualification: The ICND1 (640/822), and the ICND2 (640-816). 'ICND' means 'Interconnecting Cisco Networking Devices', however the 'ICND1' examination is also called 'CCENT' ('Cisco Certified Entry Networking Technician'). While all this can seem like a mouth full (as often seems the truth with IT abbreviations,) the easiest way to do this qualification is as a grouped together 'CCNA' (640-802) examination. This particular track would hugely benefit from being combined with the CompTIA A+ and N+ certifications, because they provide all the important 'grounding' before having a go at the more specialised Cisco-specific exams. A merged training-package such as this would take around twelve months to finish if training part time. As with just about all technical study programs, 24 hour direct-access student-support ought to be offered to help you to study and ask questions whenever you want to. The right studying materials are crucial - go for inter-active multi-media disc-based programs, & an accredited and effective examination prep system.
