The Juniper Networks Certified Associate-Junos (JNCIA-Junos) exam certifies a network administrator's proficiency with the Junos operating system. It's the first prerequisite for advanced Juniper certifications such as JNCIS, JNCIP, and JNCIE and a key competitive factor in your job search. This course teaches the concepts covered in the first two exam objectives: Networking Fundamentals and Junos OS Fundamentals. Learn the basics of the OSI networking model, the devices at the different layers, and IP addressing and subnetting. Then explore the core elements of the Junos OS, including the software architecture, routing, and traffic processing, and learn how to install Junos on a virtual machine.
