New Juniper / Junos networking, security basics and tools

This intensive course is designed to provide participants with a comprehensive introduction to Juniper/Junos operating system features, usage, Juniper architecture, technology and tools. The course is 50% practical and 50% theoretical.

The course will also help prepare you for the basic Juniper Networks Certified Associate (JNCIA) certification (exam fee not included).

The course is recommended for future network professionals, network operators and system administrators who will be responsible for the future implementation and operation of Juniper network devices and systems, and who want to acquire the necessary basic operational and technological knowledge. The training is also useful for those who are already familiar with other network technologies (e.g. Cisco, Huwaei, Avaya) but would like to learn about the specificities of Juniper systems.
