Junos, Associate (JNCIA-Junos) is an associate-level certification exam, taken as JN0-106, that covers networking fundamentals and Junos OS, and CertOcean's JNCIA-Junos training prepares you for it. The course starts with networking fundamentals and Junos OS basics, then builds up to the user interfaces, configuration basics, operational monitoring and maintenance, routing fundamentals, routing policy and firewall filters. Sessions mix clear explanations with step-by-step CLI walkthroughs, so it also works as a hands-on Junos OS course.
The JNCIA certification is the first step in the Junos track, which continues with JNCIS, JNCIP and JNCIE. It suits freshers and experienced IT professionals, and it qualifies you for roles such as network engineer, network administrator, NOC engineer and network support specialist. On September 15, 2026, the Juniper networking certification program was renamed, and the JNCIA-Junos credential name stayed the same.
