    Pls guide me, how to prepare for CCNA exam and other Cisco Certification Exam (Such as CCNP)?

  5. Dennis. Just follow the exam blueprints on Cisco’s web site. There are plently of cert guides out there. I generally stick with Cisco Press and maybe take in a few CBT nuggets on the way. Good luck!

  6. Hello Darren

    Can you make guide to build CCIE Lab from scratch. What is the topology and how to connect? what knowledge you have to have to configure in UBUNTU?
    I know it is here but if possible can you make step by step?

  7. Hello Darren,
    Appreciate your effort in putting together all those materials for any CCIE aspirant. I am now preparing for CCIE Lab and I find your blog is very useful. I too would like to build my own Hybrid Lab using GNS and real switches, could you please list out the detailed steps for building Hybrid Lab?


  8. Rafi, I’ve already got the info for how to build it from scratch, I’ll try and consolidate all the information into a single post :)

  10. Hi Darren,

    I’m currently studying for my CCNP and had set up a blog to record some of the tasks topics I have stuggled with.

    How did you go about getting a job that gave you more hands on experience with Cisco kit? Did you first pass your exams and get your qualifications or did you get hands on experience and work your way up?

  13. Hi Darren,

    I have known your blog through Daniels quest for CCIE blog. I want to congratulate you for this quality blog. I have just started my journey to CCIE lab and I plan to take the exam around Dec2012. It will be nice to hook up there via google talk.

    Have a nice weekend.

  14. Hi Daniel,

    Just a quick question if you dont mind.
    I have the same setup as you (2 x SUN cards and 1 x Broadcom).
    I haven’t been able to change the MTU on the SUN cards and I was wondering if you are having the same issue.

    What driver are you using for them?
    I have tried on both the latest version of Ubuntu and then downgraded to 9.10 as I saw it suggested.

    Any advice really appreciated!

    All the best,


  15. Hi Shane.

    I only had the problem with MTU when I upgraded to Ubuntu 10.something (I can’t exactly remember which version)

    This is what I’m currently using without any issues:

    [email protected]:~$ lsb_release -a
    No LSB modules are available.
    Distributor ID: Ubuntu
    Description: Ubuntu 9.10
    Release: 9.10
    Codename: karmic

  16. Hi Darren….

    congratulations for the site. I am going for the LAB in June 11th, and i found out your site very, very interesting.

    keep the good work !

    cheers from Brasil

  17. Hi Daren,

    I’m currently studying for my CCNA, later CCNP.

    I just want to know from you, in installing and configuring GNS3 on my PC, will this simulator covers the CCIE lab practice (configuring and troubleshooting)?

    Thanks man, goodluck on your CCIE mission!

  18. How very unoriginal of you… or was it me?

    Another Darren working on his CCIE who has moved from his home country to another :)

    Good luck with your quest. I am actually getting my CCIE since I’m now a CCSI with a CCNP and the CCIE will mean I can teach courses that are at a higher level… like from the 360 program. I am hoping/expecting to pass the written in August.

  19. Hi Darren,
    Nice blog you have here.
    I’m working on updating my CCNP to v6.0 then I will go for CCIE.
    I also have an IT forum which is under construction. I hope you will
    be a contributor once I’m done destining it. It’s called africanITprofessionals.net and I have a Facebook group by the same name with over 2500 members.

    I wish you good luck with your CCIE journey.


  20. Hi Darren,
    could you please guide where to get the indepth info about the TCP header & IP header with real time example.

  21. Hi Darren. Congratulations on your CCIE success! Can you identify what has been the biggest force multiplier in applying your motivation toward the goal of becoming a SP Architect? I suspect you would rate certification tracks highly for their utility in providing structured learning goals but affirm the key ingredient is hands-on experience, and lots of it. How did you compose your strategy?

  22. When did you get two CCIEs!??! I spend a year in a third world country and come back to you being a double CCIE? NICE!!!! Congrats!
