IntroductionFigure 1. The Halifax CCIE Lab
When I first went to the CCIE lab, there weren't very many books available and little was known about the CCIE lab, except that the labs had a reputation for being extremely difficult. Any regular reader of the Cisco mailing lists at groupstudy.com will often see questions posed to the various lists about the best way to prepare for the CCIE lab such as: "What are the best strategies to use?" "What is the lab like?" "Where should I go to take the lab?" and many more. This Tutorial answers these questions within the bounds of Cisco's strong nondisclosure agreement. This paper will discuss in detail how I prepared for the CCIE lab in routing and switching and give some lengthy advice about how to prepare for the lab exam. With these thoughts in mind, let's get started!
Each CCIE candidate must sign a very strict non-disclosure agreement (NDA) before attempting the exam. You can view the non-disclosure agreement by examining the CCIE sections of Cisco's web site. It is very important that each candidate adheres to this nondisclosure policy for several reasons. I have heard of very dire consequences for those who violate the NDA including the revocation of CCIE status, prohibiting the candidate from attempting the exam anywhere for a very lengthy time (a year or two), or never allowing the candidate to attempt the exam again. There is a long-term effect of the NDA as well. If the CCIE certification is to maintain its reputation and integrity, then each candidate must pass the exam using his/her own skills and abilities. The proven ability to perform under pressure is what separates the CCIE from all other certifications and makes it so valuable. For these reasons, this paper adheres strictly to this non-disclosure policy. Any direct references to the CCIE examination format and content are based on Cisco's publicly available material including the Cisco web site , Networkers CCIE Power Sessions, and public interviews with Jeff Buddemeier (Cisco's CCIE Program Manager). I will not disclose any material that will violate the NDA that I signed. Cisco has a strict non-disclosure policy about all exams, but especially the CCIE lab exam. I will in no way compromise the integrity of the exam or my own CCIE status, please don't you do it either.
One of the questions I see a lot is whether you should first go for the CCNA or the CCNP before attempting the CCIE. My answer is that it depends. I personally did not go the CCNP route. My company did not recognize it, so it was not worth pursuing for me. If your company will give you a raise or if you prefer a methodical progression, then perhaps CCNP is something you should consider. I know that if you work for a Cisco partner, they will love for you to get a CCDP, which requires the CCNP, first, but don't feel that you must go this route. Please note that my recommended lab preparation blueprint assumes that you have already passed the written exam and have subsequently scheduled your lab exam, since the backlog is approaching something like six months. This works to your advantage because you are going to need a good six months of preparation time. If you are going to embark on this quest, then you need to be realistically prepared to put in 300-500 hours of preparation time. Your preparation needs to start by examining Cisco's official CCIE web site.
One of the best sources of information about the lab exam is Cisco's web site itself. If you examine the CCIE section, you will find a wealth of beneficial information. For example, if you examine the latest news, you will find that certain topics have been removed from the lab exam including LAT, DECnet, Apollo, Banyan VINES, ISO CLNS, XNS, ATM LANE, X.25, and AppleTalk. You can also find out that any IOS feature through IOS version 12.0 may be included in the exam. You will also see that there is an equipment list, for which you are responsible:
• 2500 series routers
• 2600 series routers
• 3600 series routers
• 4000 and 4500 series routers
• 3900 series Token Ring switches
• Catalyst 5000 series switches
Why is this important? Have you ever configured a 3900 series Token Ring switch? If you haven't, you better find a way to learn. Trying to do something for the first time during the lab is not a good idea. Ideally, you should have seen every feature at least once prior to the lab. Here are some additional examples: do you know what the differences are in password recovery procedures for the various routers and switches? Again, the lab is not the place to learn them.
The Cisco web site also includes other important topics such as how to book the exam, where the exams are held, and how much the exam costs. You should frequently check the appropriate web sites because this is, after all, the official source of information.
A lot of people wonder just what the exam is like since the strict NDA keeps you from learning much about the exam until you experience it yourself. This same NDA prevents me from sharing much, but you can get some idea of what the exam is like from the official web pages and from the 2001 CCIE Power Sessions at Networkers .
Networkers is Cisco's annual user conference held several times a year throughout the world. At networkers, you can receive detailed technical information about virtually any Cisco product or technology at levels ranging from the most basic to advanced beyond the CCIE level.
At Networkers, Mike Reid talked about the general makeup of the exam. The lab consists of a two-day practical exam with the first day being devoted to building a network to meet a set of specifications. After the first day is completed, the proctor grades the exam and reviews the results with the candidate. The exact time of the review varies depending upon the location of the exam. The review could be the evening of the first day or the morning of the second day. Day two begins by having the candidate build upon the first day's network until a break is taken at lunchtime. The proctor will again grade this work over lunch and review the results with the candidate. Finally, the candidate will troubleshoot a network in the afternoon. At each major break, the candidate must obtain enough points to pass on to the next section. If the candidate does not score enough points, then the lab is over at that point. The lab exam is particularly difficult because the candidate needs to score 80% in order to pass the exam.

Lab Tip: An excellent tip to take with you into the lab is that although the rules say you may not use any static routes, if you are having difficulty solving a particular problem, and later questions depend on solving that problem, go ahead and put in the static routes. Sure, you will lose points for doing it, but you may save more points by being able to make the rest of your lab problems work. You can always go back later and remove the static route to fix things the correct way if you can figure that way out. |
The network specification is presented as a series of questions. These questions can be completed in any order, but some later parts may depend upon successful completion of earlier parts. The point values for each question are shown on the exam paper. If you view the presentations from the Networkers CCIE Power Session, you will see a sample topology and question. It is worth noting that there are no partial marks given. Each question is either 100% correct or 100% wrong to standardize grading around the world. You should also be aware that some questions can be solved numerous ways, all of which are equally correct. As long as your solution meets the requirements of the question, you should get credit for it. You should also be aware of the lab rules so that you can incorporate them into your practice and study sessions. For example, during a recent Networkers CCIE Power Session, one of the rules presented is that, unless a question explicitly states that you can, you may not use any static routes or default routes. You need to be emotionally ready for restrictions such as this, which don't reflect the real world but are what you need to do to pass Cisco's lab. One very distinguished consultant failed the lab because she immediately began to argue with the proctor that some scenarios were unrealistic, and lost valuable time. The scenarios were unrealistic. So?
A review of the groupstudy.com archives for the CCIE lab mailing list shows that a lot of people wonder about the physical makeup of the lab. According to the above Networkers CCIE Lab Power Session, each candidate has his/her own PC and rack of equipment. Physical connections may be made using RJ-45 and serial patch panels at the front of the rack. Since you already have a list of the possible equipment in each rack, you must be prepared to work with each different type of equipment. You will probably find that the exact equipment you will have in your rack during the exam depends on where you are taking the exam and which rack you have. I would not get too wrapped up in worrying about the exact rack equipment list. If you have any questions about particular equipment, you can ask the proctors before or during the exam or you can ask the people at Cisco who schedule the exam.
For example, I called Cisco and asked if they could tell me if I would need to know how to configure the 3920 Token Ring switch or if they would just have old-fashioned MAUs. At that time, a representative of the CCIE program told me that, although they would have 3920 Token Ring switches present; they would only be used as MAUs. Please be aware that this was over a year ago. You must check for yourself at your particular lab. Another example of how you can get help is to ask the proctor how to use an RJ45 or serial patch panel. If you have ISDN present on your lab exam, you might want to ask the proctor what the ISDN switch type is or similar questions. Now that you have a basic understanding of what the lab exam is like within the bounds of the NDA, there are a number of further actions that I recommend you take to prepare for the exam.
