In this article, I will take you on my certification journey for JNCIA-Junos. Juniper certifications ensure that you have digested the most current knowledge and have the aptitude to work with the technology that is relevant today. 

Disclaimer: Dear readers, please note that this blog is a bit older and therefore the content, insights and statements may have changed over time as products, services and technologies evolve.

JNCIA-Junos, also known as Juniper Networks Certified Associate, is the entry-level for “Service Provider: Routing and Switching” or “Enterprise: Routing and Switching” certification track”.

If you are new in the networking field, or newly into working with Juniper devices, JNCIA-Junos builds a candidate’s understanding of networking fundamentals, as well as the core functionality of the Junos OS. Unlike other network operating systems, Junos OS is a cohesive operating system that is supported across all devices and product lines ranging from switches to routers, to firewalls. The exam consists of 65 questions, with a minimum passing score of 60% and you can take it either from home using remote proctoring or in a certified testing center.

For you to successfully pass this exam, you need to become familiar with the following topics:

  • Networking Fundamentals
  • Junos OS Fundamentals
  • User Interfaces
  • Junos Configuration Basics
  • Operational Monitoring and Maintenance
  • Routing Fundamentals
  • Routing Policy and Firewall Filters

I started my journey without previous experience of working with Juniper and limited networking knowledge. After a few months of self-study, I managed to pass the exam and considerably increase my skills. Online training is available on different platforms. I tried multiple ones, but the best free study material I found was on Junos Genius.

Here you can find two relevant courses:

  1. Getting Started with Networking
  2. Juniper Open Learning: Junos, Associate (JNCIA-Junos) – Recently Juniper made this course available with no costs. Participants who complete the program and meet the requirements can earn a voucher to take their Junos, Associate (JNCIA-Junos) certification exam at a discounted price.

Additional free training to support Juniper skills is available on this link (under the “Get started for free” section).

After identifying suitable training material and spending many hours watching video tutorials, I was still feeling like I didn’t know enough. Not because of the amount of the study material but because of the way I learn. There are four different learning styles: Visual, Auditory, Reading/Writing, and Kinesthetic. For me, it was feeling unnatural to learn from video tutorials, so I took a pen, took notes and learned in a classical way. At this point, I was able to read from the notes and my brain was able to assimilate much better the new information.

The certification program has four levels: Associate, Professional, Specialist and Expert. As there are no shortcuts on the path to success, you must pass each level in order to become an expert. The secret to passing any exam, besides available training material, is knowing yourself and your learning style. Good luck!
