Hi, my name is David Roy; I have been working for Orange for the past four years in the Network Support team for the Domestic Backbone. Here’s a short story of my Juniper Networks certification journey, which took me just under two years to complete.


My Juniper certification journey started back in 2010 with the M/T track, which was the closest certification related to my job. At the time the books from Harry Reynolds were available and constituted most of my learning for this certification track, I found these to be awesome books, which helped me a lot. I would recommend that you try to get hold of these books if you can, you might have to try the second hand market on ebay. Next up was the JNCIS-M/T; to be honest I didn’t find this track so difficult. After that, I then prepared for the JNCIP-M/T Lab (actually, the P level of the old track was an eight hour lab exam.) To prepare myself for this exam I used a Junos emulation (called Olive), with ten logical systems. All topics for the P level are well implemented in Olive. The first lab was so impressive after two hours I passed, so to configure my topology and playing with several interfaces I was a little more relaxed and I finished the final exam in eight hours (no more, no less). The preparation of my JNCIE-M/T was done by using Olive again for the IGP/BGP/VPN configurations. Nevertheless, I used a real MX960 to prepare the L2VPN part (not well supported by Olive). The E level was much more difficult, the IGP topology was quite unstable. I was so stressed and I spent a lot of time debugging it, and unfortunately I didn't have time to finish the entire exam (so I lost critical points) a little disappointing at the time. Needless to say I didn't pass the JNCIE the first time. However, second time round for JNCIE I was much better prepared for the troubleshooting part as I had created more scenarios in my own lab, which I think armed me with a better understanding and knowledge going into the exam, I finished the exam on time and I passed the JNCIE-M/T in December 2010.


At the start of 2011 I had planned to begin my second certification track: ER, but during the year all the Juniper certification tracks had been changed: M/T became SP and ER became ENT. So, I started studying the enterprise track, I more or less used the Juniper site and its technical documentation, which helped me pass the sample written exam as well. I passed the JNCIS-ENT in February 2011. Before starting to study the P-ENT level and in order for me to finish a complete track, I passed the JNCIP-SP written exam which allowed my JNCIE-M/T to become a JNCIE-SP. It was completed during July 2011.


Then, I started studying JNCIP-ENT using Junos Enterprise and Routing 2nd Edition, and Junos Enterprise Switching - more awesome books and I recommend you buy these books if youre studying this level. With this good preparation in hand, I passed the JNCIP-ENT in November 2011.


Next step: I want to pass the JNCIE-ENT during Q1 2012. In order to do this I will use a lab I have already created with two EXs, one SRX and one MX960 to prepare for it. In parallel, I believe I will be able to pass the JNCIS-SEC written Exam. I'm also very interested in trying out the security track, and will need to schedule this in at some point.


All in all what can I say? I just love Juniper certifications. I would be interested in hearing how you’re getting on with your certifications, so drop me a note in the comments field below.
