Heres the deal on the Cisco CCIE certification
(Cisco Certified Internetwork Expert)
Cisco generally says that it takes 6 years of experienve before you have the proper backend knowledge to successfully pass the stated requirements for this cert.
There are 4 "specializations" of the CCIE cert
CCIE Routing and Switching
CCIE SNA/IP Integration
CCIE ISP Dial Up
CCIE WAN Switching
Then there is the CCIE design cert
Regardless of what track you decide to follow, you first have to pass a 2 hour 100 multiple choice question exam. Then and only then, depending on if you pass or not, are you invited to one of 11 locations around the world where there are labs setup to handle this test. The two in the US are in San Jose and the other is in North Carolina, for Canada its in Halifax.
After you pass the gruelling 100 question test in under 120 minutes, you then get to do the lab.
The lab is 2 days, and costs a 1 thousand dollars per attempt.
Day 1 consists of you being taken into a room, shown a table full with a few million dollars worth of network equipment, a box in the other corner full of rj-45, fiber optic and other cabling, then a sheet of paper outlining what it is they want you to do with all that stuff. You have all day to complete the outlined task.
Depending on how well you do on the first day, they may or may not let you continue with the 2nd day. Then 2nd day is when things get fun

On the 2nd day, a cisco rep will walk into your beautifull network creation that you spent all day setting up, configuring and tweaking to make it work just right and fsuck it up! could be anything from takin a hammer to a fiber cable or formating a few routers routing tables or any number of numerous things!!
However what they WONT TELL YOU is that before you get a chance to a) find out whats wrong and b) correct it back to its previous working state, the test lab will send in an allready certified CCIE and time him to see how long it takes him to find `n fix the problem. When you go into the lab you then have to come within a certain percentage (+/- 30-45 mins i think) of that guys successfull resolution of the problem. If you take WAY to long, you fail.
you must achieve 80% for all tests, and they are EXTREMLY PICKY.
There are just over 3,000 CCIE's, half of which are in the US. The majority work for Cisco or cisco gold/silver/platinum member corporations.
The only other networking exam that comes CLOSE to trying to pull off what cisco has done is Red Hat with their RHCE cert (Red Hat Certified Engineer), you have to take a lab in order to get their cert.
There is also alot of talk of adding a lab requirement to the CCNP exam as well, i wouldnt be surprised if its implemented later this year.
IF only microsoft required one of its core exams to be done via a lab, the MCSE certification would carry alot more weight than it does now. For win2k why dont they make em take a computer, install Win2k Server, setup active directory, create a few users, make a tree or other OU's, setup a lil firewall and be done with it? Let the person only have 3 chances, have to wait 3 months between each chance... i mean every major testing center that is listed with sylvan or pro vue HAVE COMPUTERS, cuz they dont make their money off of hte percentage they get on teh 100 bucks per test, they make their money training other people, so why not make every testing centres requirement to be a MCSE testing center to have one or 2 spare systems dedicated to a MCSE lab exam requirement. You could setup a 2nd system to fake a larger network, i mean IT WOULDNT BE THAT HARD TO DO, but microsoft wont do it. This is one reason why i have no desire to upgrade my NT4 MCSE to the Win2k MCSE.
So when i say the CCNA is an 'entry' level cert, i mean that in comparison to the CCIE. The CCNA is 'okay' but its just that, an entry level cert, but everyone has to start somewhere right?
BTW to pass the CCIE exam you need
NOT be a CCNA or a CCNP, however no one that i nkow of has passed the CCIE without hvaing gone through the other 2 cert processes hehehe
hope that helps those looking at taking hte cisco course.
If your into networking there are other paths
Citrix, Novel, Security (CISSP, SANS GIAC, Checpoint CISA etc) of course cisco, but novel also has their own cert process, same with intel and 3com. There are others i just cant remember.
