Designed for experienced networking professionals with beginner-intermediate knowledge of networking, this written exam verifies the candidate's understanding of the Juniper Networks Junos OS, networking fundamentals and basic routing and switching.
Maybe you've never taken a Juniper certification exam, even though you work at a company that uses their products exclusively. If you want to distinguish yourself from your fellow employees, then getting the JNCIA-Junos will help you do it. It demonstrates to your manager that you have the hands-on experience to install, monitor and maintain the Juniper equipment that they have on-site.
You also show that you possess the theoretical knowledge that the Juniper ecosystem of certs requires. There are other benefits too, potentially. Certification could help you to get a promotion or a pay raise because you've validated that you have in-demand skills. Once you have gotten started down this certification track, more doors will open in your career as you build up your skills and qualifications.
As mentioned earlier there are no required prerequisites for this exam. If you have previous experience with basic networking concepts or certifications like CompTIA Network +, then that will make your exam prep much easier. But this is not a requirement.
