Juniper JNCIS-ENT: Enterprise Routing and Switching Specialist (JN0-351)

Enterprise Juniper networks create operational risk when switching, routing, redundancy, and IPv6 practices vary by administrator. IT Directors and Team Leads assign this intermediate JNCIS-ENT course to standardize how network administrators configure, monitor, and troubleshoot Junos enterprise routing and switching features.

The course fits network administrators with at least one year of Juniper networking experience, plus experienced IT Practitioners validating JNCIS-ENT skills. Plan for about 15.5 hours per learner, with additional time for review before the JN0-351 exam. Because the curriculum spans Layer 2 switching and security, LACP, MC-LAG, STP, OSPF, IS-IS, BGP, tunneling, chassis high availability, and IPv6, Training Managers may want to assign it in stages aligned to upcoming network projects or maintenance windows.

CBT Nuggets Playlists can help sequence this training by role or rollout phase, while Team Reporting helps leaders track completion and keep certification preparation visible across the team.

IT teams complete this training to reduce configuration inconsistency across Juniper enterprise environments and strengthen the skills needed to support routing and switching operations.

• More reliable Layer 2 operations: Administrators build a shared approach to Junos switching, Layer 2 security, LACP, MC-LAG, and STP.
• Stronger routing decisions: Teams review advanced routing concepts and design/configuration practices for OSPF, IS-IS, and BGP.
• Better troubleshooting readiness: Practitioners learn the technologies behind BGP path selection, tunneling, chassis high availability, and IPv6 services.
• Certification-aligned upskilling: The course maps to the JNCIS-ENT JN0-351 specialist path, helping Team Leads support Juniper skill validation without relying only on ad hoc study.
