Study Review Day 4

Well as you can see day 3 was a wash out, these things happen when you get yourself in the shit with your missus and the only way out is to apologise and take her out to dinner!  That’s not to say I didn’t get some subnetting practice in, I am starting to think the only thing I will be good  at will be the subnetting part of the test as that seems to have sunk into my brain quite well.

Day 4 study was a bit unorthodox, tonight I haven’t managed any subnetting, I have spent the better part of 3 hours configuring my 857w so I can finally give back the FortiWiFi 60c to my work (what an unintuitive heap of shit, but more of that another day), I started with a config we got from Internode (my ISP) and after some swearing and quite a few Jacks I now have a functioning router, I’m on the internet, my WiFi is working as expected, I just need to work out some external access (SSH) and I’m set.  I have just learnt that to be able to use the wireless and the wired interfaces you need to enable bridging (bridge 1 protocol ieee and bridge 1 route ip), assuming you want your wired and wireless clients on the same subnet, then then add the interfaces you want to “bridge” to the bridge group.

I am pretty happy with the way this come together I got to finally implement my router and spend some time at the CLI, as you can see apart from the subnetting I am struggling a bit to work out what I should be studying to prepare for the ICND1 exam next week.  Even though most of what I have just achieved will not be tested on the exam at least I have spend some time using the CLI.

I will be spending the next few days going through the blueprint and making sure that I have an understanding of what I should expect on the exam, and making sure that I have an understanding of what I am expected to know.

Study Review Day 2

A pretty poor effort on my part last night, due to the heat and a headache I only managed an hour of subnetting questions and some half hearted configuration of my CISCO 857w (intended for use at home).  On the plus side, I got all the subnetting questions correct and my speed is improving slightly.  Hopefully I can put in a better effort tonight.

ICND1 Study Review Day 1

Today I started my study review for the ICND1 exam.  I am planning on booking the exam for 10 days time, so I have decided I need to do at least 2-3 hours of study/review each day before the exam.  I started out by doing an hour of subnetting review.  I am using for the actual questions, I find that this is a good resource as the questions are quite varied and if you do not read the question correctly you can come unstuck.

Unfortunately this is exactly what I am finding I am doing.  I think I have a good grasp on subnetting generally, however I am still making rudimentary mistakes with some of the basic subnetting questions.  Questions that require you to work out the number of subnets in particular (I am planning a subnetting article so I wont go into the details in this post), for example I know that to calculate the number of subnets, you take the number of bits past the classfull subnet mask and raise 2 to the power of the number of (borrowed) bits, this gives the number of subnets.  However when I do the actual math I tend to look at the binary chart I have on the page and end up counting that 2 to the power of 2 is 2, when it is is clearly not.  I am planning on memorizing 2-3 tables of information which I am going to write down first thing when I get into my exam and the powers of 2 will be one of them.

After about an hour I was happy that the subnetting was substantially better than when I started so I decided to take a practice exam, I scored 90%.  I am not putting too much stock into this because it is the only practice exam I have and I think I am at the point where I have memorized most of the questions, I am using this as a way to get my speed up on the subnetting questions and the simulations.  I have found that I still make some rookie mistakes with some questions so I made a list of the points I am having issues with and will put some focus on them in the coming days.  I then read through my notes from the cisco press book and took another look at the chapter summaries.

I am going to make sure to memorize the TPC/IP and OSI layers, the powers of 2 chart as well as the  private IP address ranges, I figure the more that I write down first thing once I am in the exam the less time I have to spend later regurgitating  it while trying to answer questions and keep my speed up.

I am confident that if I keep this up I will be able to pass the exam first go.
