The JNCIA-Junos (JN0-104) is Juniper Networks' associate-level certification that validates a candidate's understanding of networking fundamentals and the Junos operating system. It covers core topics including the Junos OS architecture, routing and switching essentials, routing policy, and firewall filters. The exam is designed for networking professionals who work with Juniper devices and want to demonstrate foundational competency. Holding JNCIA-Junos is a prerequisite or stepping stone to Juniper's more advanced specialist and professional-level tracks.

Juniper does not publish a fixed numeric passing score. Results are reported as pass or fail, with a passing threshold of roughly 70% correct answers.
The exam contains approximately 65 multiple-choice and multiple-response questions to be answered in 90 minutes.
The exam covers Junos OS fundamentals, routing essentials (OSPF, BGP basics), switching concepts, routing policy and firewall filters, and basic network management.
It is considered entry-level and manageable with 40–80 hours of study. Familiarity with basic TCP/IP networking makes it significantly easier.
The certification is valid for 3 years. You can recertify by passing the current JNCIA-Junos exam or any Juniper professional-level exam.
It is ideal for network engineers and administrators who work with or plan to work with Juniper equipment, and for those starting a Juniper certification track.
