My Certification Journey
Share and learn from real life stories of those who are on the path to become Juniper Certified

When I joined my employer’s Backbone Support Group 5 years ago I had several years of network engineering experience but had never worked with the Juniper platform. Since my service provider employer was using Juniper as a provider edge router platform, I had a steep learning curve to overcome. Because I had acquired several other vendor certifications in the past, I knew that studying and testing for a Juniper certification would be an effective method of acquiring the needed skills. I immediately began work on the level 1 (JNCIA) and received the certification within 6 months. This was before Juniper did the revamp of their certification program in 2010 and their Level 1 cert was geared toward experienced network engineers that were new to the Juniper platform which met my exact situation. In preparing for the JNCIA I relied extensively on the study guide written by Soricelli (Juniper Networks Certified Internet Associate) which Juniper provides free of charge. Although getting a bit dated in coverage, it is still an excellent source and among the best technical books I’ve ever read. (


Although completing the JNCIA was a huge help in getting up to speed on Juniper routers, I needed some advanced knowledge in my position so I began work on the JNCIS-SP. In meeting the requirements of   the JNCIS, I was able to move to the upper level of knowledgeable Juniper support personnel in my group. Although I could have just read through the material without working on the certifications, I believe the accountability of passing the exam enforced a rigor in my studying that I would not have otherwise applied.


In preparing for the JNCIS I again relied extensively on the Juniper Networks

Certified Internet Specialist study guide written by Soricelli, also a freebee provided by Juniper ( Although the JNCIA version was sufficient, there were several additional areas included in the JNCIS test since the Soricelli book was written so I requested and received the training class Junos MPLS and VPNs (JMV) from my employer. Because my employer is heavily involved in providing VPN services this material was especially helpful to me to meet my responsibilities.


Being JNCIS certified gives our group credibility and saves time when we need to engage higher tier support since they can assume we have eliminated all but the most complex resolutions. I am currently working on a Level 3 (JNCIP) certification which will provide additional prestige to our group. Juniper certification – especially higher level certification – definitely adds competence and credibility to our group.

After moving to my current role, I was confronted with racks of Juniper switches and told by my new manager we have these and lots more at our remote sites. Coming from a Cisco background and with no Juniper experience, I felt the lump in my throat at the prospect of having to get to grips with a different platform and CLI.



BLOGGING CHALLENGE:My Journey towards an expert level

When I started thinking about an expert certification I never thought that I could reach this level in short span of time. Here is my journey. It was when I joined Juniper Networks that I decided to work towards an expert exam. Looking at the syllabus it was clear that there were a lot of new technologies which I needed to get hands–on experience with before attempting the exam. I decided to make a time table for myself and put a target of eight months to complete the whole process.



BLOGGING CHALLENGE: My real world benefits from studying for the JNCIP-ENT

by bjayne ‎08-29-2014 11:51 AM - edited ‎08-30-2014 12:53 PM

I currently have a JNCIS-ENT and am in the process of studying for the JNCIP-ENT. My motivation for obtaining the certifications is based on making myself more marketable in the future to potential customers or employers as the customer contract I am currently supporting begins to downsize towards the end of the year. In obtaining the JNCIS-ENT, I focused my study materials to the Juniper FastTrack Program JNCIS-ENT study resources ( The study guides map well to the knowledge required to successfully pass the test. I have also found these study guides to be good reference materials in describing the core features of routing and switching within JUNOS. In studying for the JNCIP-ENT exam, I have expanded my study materials to include O’Reilly’s JUNOS Enterprise Routing, 2nd Edition ( and JUNOS Enterprise Switching (


The most specific case I encountered where I directly benefited from my studying was while evaluating a new multicast deployment throughout the network. The project scope included selection of a multicast protocol (PIM-SM or PIM-SSM) as well as evaluation of utilizing a dynamic RP mechanism for PIM-SM. While the entire team had heard of PIM-SSM, none of us was familiar with the details of how it functioned. The timing of the evaluation perfectly aligned with my studying as I was reading the multicast chapter in JUNOS Enterprise Routing at the start of the evaluation. Based on the insight gained throughout the chapter, I was able to clearly see the advantages and disadvantages of each protocol and provide recommendations to the team on the path forward for the multicast deployment.


BLOGGING CHALLENGE Getting Certified Was So Easy Story

To Juniper Networks I came already having extensive knowledge in networking and with various certifications from Cisco, such as CCNA and CCNP. I thought it would be easy for me to conquer Juniper certifications as I already had solid networking knowledge. But I was mistaken.

Eleven months ago, I left the ‘Cisco Universe’ and came to work for Juniper Networks as a Senior Systems Engineer for the New England Commercial Team. Many folks were shocked by my decision. I had worked for both Cisco and Cisco Resellers for virtually my whole career.



BLOGGING CHALLENGE I did my JNCIP-SP and here is my Juniper Way Story

Having knowledge is good thing but getting it certified with expert institution is even better. I did exactly this. So far during my career, I have explored several networking technology aspects. With Juniper technology, I got another opportunity to raise the bar for myself. By getting certified with Juniper, my knowledge really got certified with one of the best networking equipment vendors in the universe. This recognition gives me honor.

My Journey to JNCIEx2

by ironide (cka23) on ‎04-01-2014 02:32 PM

I started my journey as a Juniper Networks Certified Instructor in August 2011.  In October 2013 Iearned my JNCIE-SEC and in Febuary 2014 earned my JNCIE-ENT.  In this post I tell that story and offer tips for your success.




As someone who spends his days preaching the value of training and certification, I was excited to see the results from a recent study we conducted with IDC on the impact of training and certification on job performance for those in networking job roles. The study revealed the differences between those with a week of training to those with less than a day. What did the study reveal? A lot!

Going to a higher Level


It was April, and my birth month. I was planning to take the JNCIS-SP exam after I passed my JNCIA-Junos last November.
