JN0-105
This JNCIA-Junos (JN0-105) training gives network administrators a working foundation in networking essentials and Junos OS. It covers the CLI and J-Web interfaces, configuration management, the control and forwarding planes, routing fundamentals including IPv4 and IPv6 subnetting, static routes, longest-match routing, and class of service (CoS), and how to build routing policies and firewall filters. Device monitoring, troubleshooting tools, software upgrades, and password recovery round out a course that follows the official exam objectives. For an IT Director running Juniper in the network, this is the documented standard administrators are held to for configuring and maintaining Junos devices. Juniper retired the JN0-105 exam on 5 April 2026 and now offers JN0-106 for the same JNCIA-Junos credential, so check the current objectives before anyone books a seat.
