Juniper JUNOS Enterprise Switching (JEX)

This course benefits individuals responsible for configuring and monitoring EX Series switches.

Attendees should meet the following prerequisites: Students should have basic networking knowledge and an understanding of the Open Systems Interconnection (OSI) reference model and the TCP/IP protocol suite. Students should also attend the Introduction to Junos Software (IJS) and the Junos Routing Essentials (JRE) courses prior to attending this class.
