CCNA - Computers

CCNA stands for Cisco Licensed Community Associate - a certification for IT professionals that's issued by Cisco Methods, Inc., some of the profitable laptop networking companies. Cisco manufactures and markets a wide range of units for both enterprises and telecommunications carriers. Cisco is an abbreviation of San FranCISCO.

The Cisco Licensed Network Affiliate is an apprentice, or foundation degree (along with Cisco Certified Design Associate), within the three ranges of certification that embrace Associate, Professional, and Expert. Principally, CCNA professionals are licensed to install, configure, and operate LAN, WAN, and dial entry services for small networks (a hundred nodes or fewer), including but not unique to make use of of those protocols: IP, IGRP, Serial, Frame Relay, IP RIP, VLANs, RIP, Ethernet, and Access Lists. The certification is valid for 3 years, after which recertification may be sought.

With a view to maintain a CCNA certification, a candidate has to pass either the Cisco Licensed Community Affiliate Examination or a mix of Introduction to Cisco Networking Applied sciences Exam and Interconnecting Cisco Networking Units Exam. Most important topics for these three exams include Planning and Designing; Design and Support; Implementation and Operation; Troubleshooting; and Technology. Different associated matters may additionally appear on any specific delivery of the exam.

There are additionally some really helpful coaching applications that could be taken earlier than the above-talked about examinations. These programs embrace Introduction to Cisco Networking Applied sciences (INTRO), Interconnecting Cisco Community Devices (ICND), and Extra Training (CCNA Prep Center Pilot). These trainings incorporate matters corresponding to basic information and comprehension of networking; the right way to select, join, configure, and troubleshoot the assorted Cisco networking units; pattern questions, simulations, e-studying modules, labs, ideas, etc.

A CCNA or CCNP candidate who desires to be totally prepared for their exams is going to place collectively a home lab to practice on. With used Cisco routers and switches more reasonably priced and plentiful then ever earlier than, there's really no excuse to not have one!

With the many completely different models out there, there's some understandable confusion amongst future CCNAs and CCNPs about which routers to buy and which ones to avoid. You may take almost any set of Cisco routers and put collectively a house lab; a part of the training course of is taking what gear you may have available and putting collectively your personal lab! For these of you getting ready to start your private home lab or add to your current one, this article will checklist the routers I take advantage of in my Cisco pods. You certainly don't must have all this equipment, however this provides you with some good ideas on tips on how to get started.

Probably the most versatile router you can get on your CCNA / CCNP home lab is a 2520. These routers come with 4 serial ports, one ethernet port, and one BRI interface for ISDN practice. This mix of interfaces means you may actually use it as a body relay switch whereas using the ethernet and BRI ports for routing. (There is no problem with using a lab router as both your body relay swap and a practice router; for a frame relay change pattern configuration, go to my web site!)

My pods consist of five routers and switches, and three of the five routers are 2520s, because of their versatility. A current ebay search confirmed these routers promoting for $99 - $125, an outstanding value for the practice you are going to get.

I additionally use 2501s in my home labs. These have fewer interfaces, but the mixture of two serial interfaces and one ethernet interface permits you to get plenty of practice.

A combination that works very effectively is using three 2520s; one as my devoted body relay change, one as R1, and another as R2. Add a 2501 as R3, and you'll have a frame cloud connecting R1, R2, and R3, a direct serial connection between R1 and R3, an Ethernet segment that includes all three routers, and an ISDN connection between R1 and R2 when you have an ISDN simulator. That combination will let you get a tremendous quantity of observe for the exams, and you may all the time promote it whenever you're finished!

2501s are very reasonably priced, with many within the $50 range on ebay. It's quite possible to get three 2520s and one 2501 for lower than $500 complete, and you can get most of that money back in case you select to promote it while you're done.

With four routers to work with, you're in all probability going to get uninterested in transferring that console cable around. An access server (really a Cisco router, not the white bins we have a tendency to think about once we hear "server") will enable you out with that. An access server means that you can set up a connection with each of your other routers by way of an octal cable, which prevents you from moving that console cable around continually. For an example of an entry server configuration, just go to my website and look in the "Free Training" section.

Access server costs differ fairly a bit; do not panic in the event you do an ebay search and see them costing thousands of dollars. You do NOT want an expensive access server in your CCNA / CCNP dwelling lab. 2511s are great routers to get on your access server.

One query I get typically from CCNA / CCNP candidates is "What routers ought to I buy that I can still use when I'm ready to study for the CCNP?" The CCIE lab changes commonly and typically drastically with regards to the gear you may need. Throughout my CCIE lab studies, I discovered that renting time from on-line rack rental providers was actually one of the simplest ways to go. Don't hesitate when placing your CCNA / CCNP home lab together, wondering what might be acceptable for the CCIE lab a year or so from now. None of us know what is going on to be on that equipment record, so get the CCNA and CCNP first - by constructing your own Cisco home
