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

Certificar JNCIS-SP me abrió la posibilidad a una troubleshooting mas eficiente, acorde a los conocimientos

adquiridos a través de las prácticas. Recuerdo uno de los casos puntuales, en donde me encontraba

analizando una configuración de OSPF, en la cual dos neighbors no podían establecer adyacencia entre

si. "Show ospf neighbor" me daba la información que el estado del vecino estaba en "2WAY". Revisé la

configuración en varias oportunidades, no encontrando el error: Las IPs estaba correctamente configuradas,

lo mismo con el área de ospf, y las interfaces asociadas a esa área. Los timers se encontraban por default, 10

segundos Hello timer, 40 segundos el dead timer. A través del comando "show ospf interface", advertí que a

través de la misma interfaz se levantaban otras dos adyancencias, en el cual el estado era "FULL". Luego de

unos minutos, recordé que uno de los slides, estudiados en el curso JIR (https://learningportal.juniper.net/

juniper/user_activity_info.aspx?id=2321) , hacía hincapié en que en un segmento broadcast, solo se

establecen adyancencias con el DR y el BDR de la red, por lo que con los demás equipos el estado "2WAY" no

indica ningún problema, solo hace referencia a que ambos equipos no son DR ni BDR del segmento.

Sin haber estudiado para la certificación, hubiera sido dificil entender que allí no había un error, sino

que era un estado normal de acuerdo al rol de cada equipo en la red.

 

Es muy interesante pensar que estudiar para la certificación nos provee de numerosas herramientas,

que nos ayudan a entender con más profundidad el funcionamiento de cada uno de los protocolos

involucrados en la red. Gracias a ello, mejora notablemente nuestro análisis crítico en cada una de las tareas

en las cuales tenemos responsabilidad, desde el diseño de alto y bajo nivel, hasta la implementación y el

soporte. Certificar, tienen un objetivo mucho mas fuerte que aprobar un examen, tiene que ver con poder ser

mejores profesionales y dar un servicio de excelencia hacia los clientes, logrando una mejor comunicación que

mejore la vida de la gente.

BLOGGING CHALLENGE: My Juniper Certification Story

by gumberamit ‎09-13-2014 12:18 AM - edited ‎09-16-2014 10:46 AM

This is the story of one of our clients who was using Nortel/Avaya data switches (Tier-2 Network) across all over network locations connected with T1’s, OC3’s and 10 Gig Fiber links. The customer is planning to move /change the network data products to new OEM and thinking of challenges that might be facing while doing the migration based on mentioned factors:

1)      Nortel SMLT/MLT supported features (High Availability with sub second failover)

2)      Nortel Switch Stacking features

3)      Nortel IP phone support

4)      Cisco LWAP Access Points support (Local and Flex connect mode)

5)      Quality of Service (Qos) support

6)      PIM and IGMP support

7)      Easiness in switches administration similar to Nortel JDM (Java Device Manager)

BLOGGING CHALLENGE My JNCIE Story

by Juniper Employee ‎09-11-2014 07:55 PM - edited ‎09-11-2014 07:55 PM

This is the story of my toughest certification ever. I had completed JNCIP-SP and I don't recall much of the struggle in achieving the same. But when I decided to get JNCIE-SP it was all different. I got a company to give lab attempt so I just booked for the lab without much preparation or idea.

I started my career in 2003 and I had never thought of learning IP network technologies on Juniper platforms because Cisco has been in the world of data networking for so long. Most of the service provider's and enterprise networks are/were built on Cisco's based platforms.

BLOGGING CHALLENGE: Starting with Junos

by enibiker@gmail.com ‎09-09-2014 07:41 AM - edited ‎09-16-2014 10:48 AM

My adventure with Junos was not planned, but it becomes more serious each day I spend with Juniper CLI. I was working as a Network Analysis but after a short time I started looking for more ambitious job. One day I saw an internal job offer and applied for it but without any hope of getting the job, because they wanted a more experienced guy with bigger knowledge. I was really surprised when they called me and invited me for an interview.

BLOGGING CHALLENGE: Getting certified without paying money! Yoohoo!

by JohnDG ‎09-09-2014 05:36 AM - edited ‎09-09-2014 05:40 AM

When we think of certifications, we want to make dough, not spend dough. That's entirely possible with JNCIx certifications! This is how an average person did it.

Networking has always been a passion of mine. The complexity of networking allows for an ever changing set of issues and problems to discover and resolve. My first real introduction to networking protocols was in college, where Cisco was a major focus. After graduating, I moved to California, first doing support then moving to corporate network operations. The environment was my first introduction to Juniper. While I knew the protocols well, my Juniper experience was lacking. I made it a mission to learn everything I could about Juniper.  While I was initially deterred by the differences between Cisco. I soon came to realize the significant benefits of Juniper over other vendors, such as delay configuration committing, unified software builds, and an underlying Linux environment that made troubleshooting much simpler and intuitive. Within weeks I took the JNCIA-Junos, and through work sponsored training, quickly came up to speed and passed the JNCIS-ENT soon after. The knowledge in BGP, Spanning Tree, OSPF and complex troubleshooting I gained from the exams and studying allowed me to excel in my position.

As a Cisco Certified Professional with a few years of experience in the networking world,

I didn't find much difficulty to support high-end Juniper SRXs with Junos in my day-to-day

support functionality because its product lines use the same golden networking concepts

with innovative implementation options.

BLOGGING CHALLENGE -- The Worthwhile Certification

by echorequest ‎09-08-2014 09:47 AM - edited ‎09-08-2014 09:49 AM

I work for one of the largest Network Service Providers on the globe. Frequently, I will be confronted by multiple-vendor networks, technologies, and architectures. Typically the first time I am encountering a network, the network is usually in a severely degraded state and impacting critical services.

BLOGGING CHALLENGE From Cisco CCNP to Juniper JNCIS and beyond

by dvampiri ‎09-05-2014 12:40 AM - edited ‎09-08-2014 12:37 AM

I took my first Cisco CCNA in 2002 when I started to work in the networking world. In my company we

had a network of Cisco routers and switches. Cisco and the networking for me was exciting. I bought all

the books and stuff for CCNP, but I didn’t ever read it, so my CCNA expired.

My JNCIA-Junos preparation started the day I passed my CCNA Voice exam. After the exam, I decided I wanted to get more certifications, and JNCIA-Junos caught my attention. I really liked how the config files are structured, but that was all I knew about Junos.

BLOGGING CHALLENGE Studying for JNCIS-ENT certification

by migueqc ‎09-03-2014 10:56 PM - edited ‎09-08-2014 03:39 PM

The reason why I decided to get the JNCIS-ENT certification was because I was working with Juniper EX Switch and SRX Router. Although I had previous knowledge of Junos, I wanted to expand it because I would have the opportunity to put this knowledge into practice in my current job. On the other hand I wanted to redirect my career into other technologies and the most interesting one was Juniper.

My name is BHARAT SONI (Juniper Ingenious Champion, JNCIA, JNCIS-ENT, JNCIS-SEC, JNCIS-WLAN). I heard about juniper before 1 year only when I was doing CCIE security training in Bangalore. After completing CCIE training I got a job in a system integrator company where I have to work with Juniper technology. So I have started Juniper track in January 2014.In these 8 month I achieved Juniper Ingenious Champion Level.  I started Juniper because I don’t want to be expert on only Cisco platform. I want be master on all products and get knowledge on all vendor platforms.

First time I failed the JNCIA-Junos. That was good experience.  Then again I prepared myself for JNCIA-Junos and passed.  I prepared with online training PDF documents, virtual simulator, and the Junos Genius app.

I am working with Junos for the last 3 years but I do not get any job offers for Juniper. My ex-boss suggests I go for Juniper certification. After earning my JNCIA certification, they told me to prepare for the next level of certification.  The most interesting think was that all costs would be paid by the company.  This offer is not just for me but for all engineers so that they can take advantage.  Now I am getting numbers of call for Juniper related jobs. Now I am preparing for JNCIP-SP

Professional certification can be found in almost every industry in the world today. Certifications show verification of knowledge and expertise as well. For IT professionals I believe Juniper's certifications are more valuable than their other counterparts, too. Juniper tests more on your general knowledge of a technology and how it works.
