Course Description
DISCLAIMER
Beginning April 1, 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 (JEX) course. The JRE course and the JNCIS-ENT Bundle (5-day) course will not be offered after April 1, 2017.
Course Description
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.
Target Audience
Designed for experienced networking professionals with beginner to intermediate knowledge of routing and switching implementations in Junos.
