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

September 2007, I was new to networking after recently graduated and a basic networking certification. My colleague shared the news of Juniper Networks Fast Track Program with student study guides, online Flash lectures; pre-assessments and free certification vouchers for JNCIA-ER & JNCIS-ER (NOTE: This material was all updated in 2010 for the new JNCIA-Junos, JNCIS-ENT, JNCIS-SP and JNCIS-SEC certifications.  Exam vouchers are now 50% off.) It was great news for a networking enthusiast and especially someone new in network industry to get a flavor of other vendors.  Juniper certainly was second famous on the list at that time. We planned to make full use of the opportunity and started register under Fast Track program.

To tell you the truth, I’m a Juniper addict; I started my networking career 4 years ago in an ISP that is mainly working with Juniper products in edge, aggregate and core layers. I was just stepping in as a new engineer and found myself working on a new software “JUNOS”. I was afraid to find it complex but since I first touched it, JUNOS became my world.

When I started working, I was thrown into the world of routing and switching. Initially, I was confused and couldn’t find my way around the CLI. However, in a few short weeks I became verse in the code and assisted in carrying out a number of deployments inclusive of the EX2200, EX4300 and the SRX100 and SRX550 devices. The major difference between Juniper and the other vendors for me personally is the separation of the processes, the control and data planes, the hierarchical structure if the CLI. The ability to segment the processes allows effective and efficient troubleshooting, restarting single processes without the need for a reboot.

Pienso que la principal motivación para un camino de certificación exitoso debe ser la búsqueda del conocimiento y el aprendizaje. De esta forma se le saca mayor provecho a todos los recursos disponibles para la preparación del examen, y se logra encontrar y explorar nuevas formas de preparación, que se adapten a cada persona. El resto de los beneficios que se obtienen de las certificaciones, como podrían ser oportunidades laborales, herramientas útiles para el desempeño en las actividades, crecimiento profesional y mantenerse a la vanguardia de las tecnologías entre otros, si bien son motivaciones útiles y validas, no nos inspiran de forma tan profunda como el deseo de aprender y comprender.

Mein Name ist Christian Scholz, ich bin 25 Jahre jung und seit Juni 2014 JNCIS-WLAN.
Das Thema WLAN und Mobile Devices wächst in unserem Unternehmen mehr und mehr, ebenso wie mein persönliches Interesse an WLAN und drahtlosen Datenübertragungen. Um mein Wissen zu vertiefen und einen Einblick in Junipers WLAN zu erhalten, besuchte ich im Mai 2014 den IJWL Kurs (http://education.arrowecs.de/seminare/kurse/training_kurse.cfm?courseId=AAAAERU) in Frankfurt.

I saw my first juniper router in year 2002 when I was asked to install a M20 router. When I opened the box I was amazed and never thought the router could look like this. It seems to be alien for me and on that day and time my love with Juniper started.

BLOGGING CHALLENGE - IPSec over MPLS

by Rodrigo Mastropietro (Rodrigo Mastropietro) ‎09-26-2014 11:22 AM - edited ‎09-26-2014 12:14 PM

Estudiar es realmente fantástico. El acto de la lectura, la comprensión y en consecuencia para poner a prueba tus conocimientos, libera la mente de las ataduras y del poco tiempo disponible de todos los días.

Hace unos meses yo estaba estudiando para JNCIA, JNCIS y JCNIP certificaciones y al mismo tiempo, en mi trabajo, he recibido el desafío de implementar una red MPLS con el protocolo de enrutamiento dinámico, failover y un nivel adicional de seguridad junto con la implementación de encryption.

Bueno todo inicia cuando decidí convertirme en JNCIS-SEC. Cuando empecé a trabajar en la empresa donde estoy actualmente, mi jefe me comento que era necesario obtener esta certificación y el JNCIA y el JNCIS-SP, nadie en el trabajo tenía estas certificaciones ya que todos me decían que era muy complicadas de obtener, muchos intentaron pero fallaron por el idioma y porque no se prepararon adecuadamente, esta certificación es necesaria para obtener el nivel Ingenious Champion.

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 on ‎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.
