JNCIS-ENT Bundle
JIR & JEX


  • Duration: 4 days
  • Price: $3,190.00
  • Certifications: JNCIS-ENT
  • Exams: JN0-347

Beginning October 2, 2017, DWWTC will teach a new version of the JNCIS-ENT course. The new version will be a 4-day version of the Junos Intermediate Routing (JIR) course and the Junos Enterprise Switching using Enhanced Layer 2 Software (JEX) course.

Course Descriptionremove_circle_outline

This four-day program includes an overview of protocol independent routing features, load balancing and filter-based forwarding, OSPF, BGP, IP tunneling, switching concepts and operations, virtual LANs (VLANs), the Spanning Tree Protocol (STP), port and device security features, and high-availability (HA) features.

JNCIS-ENT exam topics are based on the content of the recommended instructor led training courses, as well as the additional resources. The JNCIS-ENT certification is valid for three years. Recertification is achieved by passing the JN0-343 exam.
