The Junos, Associate (JNCIA-Junos) certification (JN0-105) is an entry-level Juniper certification designed for networking professionals, system administrators, and IT specialists who want to build foundational expertise in Juniper Networks technologies, routing, switching, and Junos OS administration. This course aligns with the official JN0-105 exam objectives and prepares you for managing Juniper-based networking environments effectively.

This certification validates your knowledge of basic networking concepts, routing fundamentals, switching principles, and Junos device configuration. It is ideal for those starting their Juniper certification path and serves as a prerequisite for advanced certifications like JNCIS-ENT, JNCIS-SEC, and JNCIS-SP.

Key topics include:

• Networking fundamentals: OSI model, TCP/IP, Ethernet, and IP addressing concepts

• Junos OS fundamentals: architecture, routing tables, control and forwarding planes

• User interface navigation: working with Junos CLI, operational commands, and configuration hierarchy

• Configuration basics: setting up interfaces, static routes, VLANs, and device properties

• Routing fundamentals: understanding routing policies, tables, and route preferences

• Switching essentials: working with Ethernet switching, port security, and virtual LANs

• Monitoring & troubleshooting: using operational commands, logs, and Junos tools for diagnostics

• Security basics: introduction to firewall filters, authentication, and secure access controls
