Koenig/Junos Enterprise Switching (JEX)/JN0-343

Junos Enterprise Switching (JEX) Certification Training Course Overview

Junos Enterprise Switching (JEX), a two-day course provide students with intermediate switching knowledge and configuration examples. This course includes an overview of switching concepts and operations, port and device security features, the Spanning Tree Protocol (STP), virtual LANs (VLANs), and high availability (HA) features.
 
Students will gain experience in configuring and monitoring the Junos operating system and in observing device operations through demos and hands-on labs. This course utilizes Juniper Networks EX Series Ethernet Switches for the hands-on segment, but the lab environment does not preclude the course from being applicable to other Juniper hardware platforms running the Junos OS. This course is based on the Junos OS Release 12.2R1.8.
 
Audience: This course is beneficial for individuals responsible for configuring and monitoring EX Series switches.
This course prepares you for Exam JN0-343. Test your current knowledge Qubits42
