It is my greatest honor to talk to you. I think you are only few 20,000 people who hold the Trophy.
Anyways as we start, as a lay man, we will get a lot of doubts about packet at the physical level, i think once the encapsulation process is really encapsulated then the idea becomes much clearer. I will start with the OSI model, but i will not stretch it too completely , but i will teach about all the PDU's in the first chapter, even before the layers are established and thought i would show this. and then revisit the OSI model again. I thought i knew the OSI model very well, and after let us say 4 months or rigorous , i am beginning to appreciate the OSI model.
Then, i will talk about data link, what is it..... and Really strecth about Ethernet, and really talk about Ethernet and the WAN protocols.
I would place a lot of emphasis on subnetting, as far as my observence goes subnetting is like the ABC's or networking routing protocols, cant go anywhere, i would really drill, providing them with real examples and a lot of troubleshoothing examples.
I am a sort of guy who like fun and color , so i would say add a lot of funny pictures, so that the readers understanding is consolidated.
There are 402 that have 3 or more CCIE's. Scott has four. So in the CCIE category, he is actually more elite than 1 in 402. When combined with the JNCIE, that number would go down quite a bit more. So that's just some perspective. However, the nice thing about Scott is he's really down to earth to talk to, he's very good at explaining things, and he makes the time to help the rest of us.
Labs, labs, and more labs.I am currently self studying for the single CCNA exam and I plan on taking it in 3 - 4 months. I initially enrolled in the Cisco Networking Academy at a local technical college and I received a pretty easy A in the Networking Fundamentals (semester 1) class. Prior to taking that class I purchased the Cisco Press CCNA kit which contained the Wendell Odoms books for the Intro and ICND exams and the Boson network simulator.While I never really got around to reading the books I enjoyed working through the labs in the simulator and that experience allowed me to quickly grasp the theory that was taught in the Networking Fundamentals class. I had plenty of "aha" moments when the instructor would explain a networking principle that I instantly connected to something that I experienced while working through a lab with the simulator. I would think "Aha, that's how that works!"From that experience I believe exposure to a simulator, or even better, actual equipment should be the starting point to learning networking. Throw the students on the simulator or the router and give them step-by-steps instructions for configuring a LAN and WAN connection. It doesn't matter during this time if they don't understand "why" it works just show them "how" to make it make it work by creating a connection through several devices. Give them all of the addresses and subnets masks and have them configure default, static, and summary routes. After they have done it several times go back and cover the theory, the "why", behind the configuration process and they will have lab experience to which they can connect the theory. Understanding networking theory is easier when you can connect it to an experience instead of just a diagram on a page or our imagination.Like an earlier poster stated videos are a huge help in apply theory to a learning experience, even if it isn't hands-on. I watched the CBT, Train Signal and Video Mentor videos and they were a big help and I believe watching those along with the simulator labs were why I did so well in the class. Due to work and family committments I will continue my studies independently. I purchased the other Cisco Networking Academy lab guides and textbooks from the bookstore and I downloaded Packet Tracer from the student portal. The packet tracer labs are awesome learning tools for beginners. I also have a pretty speedy computer so I can use GNS3 for working with the real IOS.I'll let you know how I do on the CCNA later this year.Loren
I actually haven't even taken CCENT nor CCNA test yet, and I don't know when I will, but I'll do my best to share my learning experience.
I'm natively Chinese (I guess you can't tell, right?), but like most Chinese, I tend to have the problem everyone is having. Repetition, repetition, and repetition. I can say I have read at least a dozen book regarding CCNA, CCENT or Network+. I don't have CBT nugget or Boson, but I did use Packet Tracer.
I really don't have much to share and I really don't understand why does it take $4,000 to take courses for CCNA. Here is how much I have spent: $70 = 40 (Safari Books Online) and $30 (howtonetwork.net).
I started from December and now it's April, and I'm half way through CCNP.
My advantage is that I have a lot of free time to study, and when I encountered something I don't really understand. I read it very slowly and then try to explain myself . When I still can't understand it and begin pulling my hair, I ask for help (a word of thanks for all those who replied to my thread). This is really the secret of my speedy study I've learned from years of homeschooling.
What methods worked for me as I prepared for my freshly acquired CCNA? Since I am a self-made man and self-study guy (which indeed takes discipline) my method was to immerse myself in the material. I bought the official certification guides (the Wendell Odom books) from Cisco Press and also let Google work overtime for additional material. I read the books cover to cover, more than once.
Also, I spent at least 30 minutes everyday studying in the weeks prior to the exams. As for practical experience, use what you got. Always type "arp -a | sort" whenever you can log in to a unix host and see if that can learn you something. Can you log in to a router or a switch, try out all the show commands available to you. And then there are always simulators of course, some even on the CDs that come with the books.
Oh, and subnetting. Make sure you are an expert on subnetting, it's mighty important.
Good luck with your certification efforts!
Just a few thing I like:
1. Flash card with definitions. I know we shouldnt memorize everything it is more about having the skill instead of passing a test I still like definitions. Personally I would like to see a short list of words at the start of a topic/chapter that we could review before actually learning the material.
2. Including a CD with PDF worksheets for different topics. I personally do not like writing in my books I actually have a notebook with my books. Any type of "homework" that I can do a day or two after ready to material to make sure Ireally understood it.
3. Sims or Hands-On is the best too. I personally work at a company with one CCNA and one CCNP above me so I can play anytime I want to on all the equipment.
Interestingly enough my method of preparation was the exact opposite of yours: I read the books, I got additional study material with Google, and reread the books some more. I didn't even bother with the simulator on the CDs, I just studied hard.
Goes to show that differnt study methods work for different people I suppose. I might have to think differently now I study for my CCNP though. ;-)
When I got a degree in databases (Oracle DBA) I thought it was boring ( really it's boring !) , like programming, too .
I asked myself what about the networks it's more fun. I have experience in the field of networks (so I thought ).
When you want to register in the course I found it very expensive, as well as routers and switches. So i went to other plan(i call it the evil plan) looking for the best emulators and crack it (don't tell anyone ) so i download programs known and famous in the simulation of networks and also download two books i read together .
The point is :reading books and I try to apply the concepts through the various simulation programs.
For SUBNET: I will invent any Network IP address and I find the required information then confirmed through programs , such as SUBNET Calculator
about the learing video , actually i watch 1 or 2 video and i find it's not helpful (for me) because it duplicate of what I have read and that it applied
also searching in google it's very helpful for finding explanations and questions to help in the preparation >
Taking an exam right now is not really my priority, I want to see what I can do and how far I can go. I'd certainly be happy to attend an exam to prove my ability when I know that's about what I can achieve.
On the other hand, I think what you are learning is quite interesting, not a lot of people are interested in wireless as security or R&S. I hope you will achieve what you wished for, and good luck.
Before I answer what seems to work for me let me give you a little background information on me. I currently work in the IT field as a Network Specialist. I have passed four of Microsofts tests for that whole MCSE-thing. I'm beginning this Cisco journey because I want the knowledge and the skills that come along with the Cisco certs. I'm also doing it because I would like to work on the infrastructure side of things and less on the server/desktop side of things. So going in I have knowledge of networking.
On the personal side of things I have a full-time job, wife and two little kids (1 and 3). So time is my most precious resource. How I have to do it is get up everyday at 4am, pick up coffee mug, pour coffee + sugar + creamer. Sit down at desk in home office. Open book and begin reading. That gives me 2 1/2 hours everyday uninterrupted where I can devote my brain and time to learning.
As for how I study. What seems to be working for me, and I say seems because my CCENT test is coming up in just under two weeks is:
I read Wendell Odom's book. I take notes and try to make sure I really understand the material. I also watch the CBT Nuggets on the related topic which helps too. I also put together a home lab so that I can get that all important hands-on experience. I find it much either to learn commands and absorb the information when I'm actually seeing it. Hopefully all of this will equal success on the actual tests. Oh and one final thing that I find very useful. And that is to take the practice test that comes with the Wendell Odom book from Boson. Once you have taken that exam once you will find your areas of weakness. Do the exam again and again if necessary until you can score high. Plus it gets you used to answering questions in a format that will be similar to the actual test.
PS--For subnetting which I have down, I did the practice problems in the book. I then went to http://www.subnettingquestions.com/ and have done tons of those problems. After about 50 of those questions you should be able to answer subnetting questions quickly and correctly.
PSS-The one thing I would like, and maybe it already exists and I'm not aware of it is a book or booklet with labs put together that would really test your knowledge of commands. For example one "lab" could be: Take an unconfigured switch and:
1) set a secret enable password
2) Setup the switch for telnet access
3) Turn off CDP for all ports except for any ports connected to a router or another switch
Does this exist?
