Juniper’s Place in the Networking World
Cisco may dominate training platforms and beginner-level conversations, but Juniper Networks holds real weight in production environments that need scalability and uptime. Telecom providers, large-scale cloud infrastructures, and regional ISPs rely on Junos-powered routers and switches for stability.
The JN0-105 cert proves you know how to work with those systems in a structured, efficient way. For professionals targeting companies that rely on high-availability networking, Juniper skills are essential, not optional.
Certification Paths After JN0-105
JN0-105 serves as the entry point for Juniper’s certification pyramid. Once it’s completed, candidates can move up to intermediate and specialist-level tracks depending on their interests. The next certs typically include:
JNCIS-ENT
Focuses on enterprise routing and switching, including protocols like OSPF, STP, and VLAN configs.
JNCIS-SP
Aims at service provider routing setups, covering topics like BGP, MPLS, and advanced interface configs.
JNCIS-SEC
Specializes in network security configurations, policy setup, and threat prevention in Junos environments.
These tracks add depth, but without a solid JN0-105 base, they’re hard to approach confidently. The associate cert builds the language, mindset, and CLI habits required across all higher-level certs.
