10 tips that I can tell you about Cisco CCIE exam preparation

10 tips Since now I’m closer than ever to my CCIE lab exam, I thought that it would be a good opportunity to share some of my preparation experience with you. Even if this post is focused of the CCIE preparation, I believe that you can take my advices into consideration even if you are preparing for some other exam.

As most of you, when I started the preparation I searched on the Internet about some advices like what should I read, how much time to dedicate to study and how to achieve the maxium results. This are only a few example, the entire list is much more longer and boring I believe.

I found a lot of tips, tricks, advices and many more. Some of them were really useful and helped me, but a lot (and I mean a lot) had no idea what they are talking about. I was dissapointed to find out that some advices there were just lines on a web page and the author had no idea what he or she was talking about, just taking the ideas from another blog (usually one which belong to a network engineer) and posting on his or her blog, webpage article.

So, why I’m writing this post. Well I hope that the way I see things and the advices that I give based on my personal experience can really help some of you.

Don’t trust everything and everybody – If somebody tell you that you should read at least xy number of books and take 1-2-3 bootcamps, stop one second and think. Compare your experience with the one of the person you are speaking to. Maybe you have 7-10 years of experience in related field and you already know most of the theoretic things. Don’t spend time reading just because somebody praise himself on mailing list or some forum with how many materials he read.

Don’t get discouraged – If you are reading on Internet (e.g. forum, mailing lists) ideas  that get you discouraged on and on…quit reading them; YOU are the only one aware of your knowledge and you have to trust yourself not opinions on the Internet. Just because somebody say that you will fail on your first attempt, does not mean that it will be like that.

Do not learn if you are tired – You will only get more tired and more frustrated. Do not compare the time you are learning with the one of other CCIE pretenders. You don’t have to learn 12 hours / day just because somebody does it. Maybe that persons has not other thing to do, no work, family, pets  or he / she are more slow learners than you. It’s not a competition who’s learning more in a day. If you are tired after a work day, just go to bed, sleep and then when you can you will learn. You’ll see that you can learn in 2 hours when you’re rest more that in 4 hours when your tired.

Don’t quit, just relax – If you encounter some problems during your lab preparation, and you just cannot see the solution, take a 30 minutes break, and maybe than you can see the task with “different eyes”. Sometime the solution is just in front of you, but you cannot see it right away.

Trust your knowledge – I’m not saying here to solve one lab or task during preparation and to praise yourself being so smart, but the right imagine about you can help. Remember that the more trustful you are in our skills, the more chances to obtain a positive results you have.

Don’t hesitate – When you are doing labs, task, questionnaires usually the first idea you have is the best one. Analyze the request correct but don’t start questioning yourself if are doing well, maybe you should apply other solution, or maybe…all of this will confuse you and give you headache. At least now you are in preparation and you can check if you are thinking in the right way. Also you can learn from your mistakes.

When you are not learning try not to think that you should do it – This is one of the most hard thing to achieve, and I have to admit that in most of the time I cannot follow this advice. But if you can, do it. As an example, you really want to see movie, you go to the cinema, but your mind is just making you think of networking, topologies, cisco and so on…At the end you will see that you did not enjoy the movie at all, didn’t relax and didn’t learn either. You gain nothing.

Do not neglect your closer ones during preparation – You will see that you have much more to earn if you give up 1-2 hours of learning in weekend and get out with your family, girlfriend, friends or pet. Try to understand that you have more to gain from their support sometimes than from those 2 extra hours of learning.

Prepare yourself – In a consistent and rigorous mode. After all any exam and especially Cisco CCIE exams are hard to pass. This kind of exams can really improve your professional and personal life.

Be kind and share knowledge to those who are in need – You never know when somebody will return the favor to you. I’m not saying here to let somebody (even more if that somebody is making money from your help) to take advantage of you, but helping make you feel better and prove to you that you didn’t learn for nothing.

Maybe you expected more technical advices and tips and you are a little bit disappointed, but I can assure you that the lines above can really help you in your preparation. Nothing is more important that to understand that CCIE exam is design to help you improve your life not destroy it. If you neglect everything in favor of preparation and then you have bad luck and do not pass it from the first attempt, you could become frustrated because you’ll realize that you spent a long time just learning and now you have nothing. This will stop you from going to the second or third attempt and you’ll end with lost time and without any degree.


Can Cisco sell ‘unified’ vision to a tough server crowd?

CiscoCisco’s biggest challenge in gaining market acceptance for its new Unified Computing System is to convince data center managers to buy blade servers from the router giant instead of from traditional, incumbent suppliers.

“Server buyers don’t have a relationships with Cisco,” says James Staten of Forrester Research. “It will be tough to convince them of the need for another player in this market.”

Cisco last week finally took the wraps off of its long-anticipated UCS platform, which incorporates internally developed blade servers and is designed to tightly integrate data center computing, storage, networking and virtualization capabilities. The blade server component has been the focus of much industry speculation over the past year, and what it might mean to Cisco’s relationships with longtime partners and blade server makers HP and IBM.

Cisco acknowledges that it will now compete with those titans in the data center blade server market. But it also claims it had no choice – and that those trying to pit Cisco and UCS directly against HP and IBM blade servers are missing the point.

Cisco buying Flip video camera maker for $590 million

flipCisco Thursday announced its intent to acquire privately held Pure Digital Technologies, creator of the Flip video camcorder for consumers, for $590 million in stock.

Pure Digital is a “pioneer” in developing consumer-friendly video with mass-market appeal, Cisco says. The acquisition of Pure Digital is key to Cisco’s strategy to expand momentum in the media-enabled home and to capture the consumer market transition to visual networking, the company said in a statement.

In addition to exchanging $590 million in stock for all Pure Digital shares, Cisco will provide up to $15 million in retention-based equity incentives for continuing employees. The acquisition is expected to close in the fourth quarter of Cisco’s fiscal year 2009.

Cisco: How to achieve network redundancy with 2 interfaces

Sometime ago, during my preparation for Cisco CCIE certification, I encountered a task that I had to admit made me think a little bit, even I should see the solution from the first minute. The idea, at least as I see it, is that as much as you learn for some certification you start to see only the complex and painful part of the networking and this made me skip over the simplest solution. Something like, I learn to fly to the moon but I forget how to step on earth…

Before I start please have a look to this network topology. The task was having some statement that due to the monthly cost, R1 should use only one line (Frame-Relay) to communicate to the networks behind R2 (I took in this example Loopback0: 2.2.2.2 /32) and in case that the R1’s protocol interface to Frame-Relay cloud is going, the connection to R3 should become active and traffic should flow through there. The scope was to achive some redundancy from R1 to the rest of the network. As I said before the solution was much more simplest that I start initially to think of and you can see it immediately.

Regarding the routing since this is not the main point discussed here, I just add 2 static routes on R1 to 2.2.2.2; one route through R2  and another one through R3 (with higher distance metric). Of course I put the necessary static routes and tracking on R2 and R3.

One advice if you want to try this on your own with this topology. Do not manually shutdown the main interface to enable the backup one, as it will not work. For testing you have to find a way that the main interface is down, but not administratively down. This is just not to get angry that this method is not working.

Cisco’s UCS: A closer look

Cisco is claiming its new Unified Computing architecture will save IT departments 20% cheaper on their hardware costs and 30% on IT running costs, compared with traditional systems.Launched on Monday, March 16, the Unified Computing System unites computing, network, storage access, and visualization resources in a single energy efficient system, the company said. This puts it into direct competition with IBM, HP and other hardware vendors for the first time.

According to Jon Oltsik, senior analyst at the Enterprise Strategy Group, this are the pluses and minuses of the new Cisco product:

Pluses

Innovative packaging that requires less rack space, power, and cooling than a standard blade server.

Designed for tight integration with server virtualization and the network.

a. Cisco Virtual switch (i.e. VN-Link) replaces VMware switch. This links virtual and physical networking policy and management.

b. Cisco adds extra memory to its server platforms, which enables it to increase the ratio of virtual servers hosted on each physical server.

Cisco manages the entire UCS virtual data center with one management platform. Cisco management can be integrated with other management platforms from vendors like BMC.

The overall strength is in integrating and improving both storage and network I/O. In this regard, Cisco could have a significant performance advantage in large data center deployments.

Minuses

Extremely proprietary architecture. Heck, Cisco is implementing its own version of Ethernet (What is more standard than Ethernet, for heaven’s sake?) to consolidate storage and network I/O. The “real” standards won’t be in place for another year or two.

This is a brand new arena for Cisco where its market share is 0 percent. With Dell, HP, and IBM well established in this market, expect enterprise CIOs to proceed with extreme caution.

The advantages of this architecture are minimal in a mixed environment. Today, all enterprises have other servers, and heterogeneous server support is not a core feature of this announcement.

Systems management has always been a Cisco weakness. HP and IBM are much better positioned here.
