Juniper Junos Associate (JNCIA-Junos JN0-103) Online Course

About the course

Ex-Cisco employees have come up with their own network operating system (OS) called the Junos OS that makes networking systems more efficient. The Junos OS is the most popular, highly modular, and scalable OS used in Juniper devices. This video course introduces you to the Junos OS and helps you master the domains for achieving JNCIA (JN0-103) certification.

The course begins with an introduction to Junos OS fundamentals and architecture and helps you to understand the user interfaces and Junos OS configurations. Once you are familiar with the basic Junos OS configurations, you’ll perform logging and tracing and get to grips with the advanced configuration functions. You’ll also explore some key concepts for successfully monitoring and maintaining the Juniper devices. Toward the end, the course takes you through the routing fundamentals and best practices for configuring routing policies and firewall filters.

By the end of this course, you’ll have a clear understanding of the important topics covered in the JN0-103 exam and will have developed the basic hardware and software skills needed to work with Juniper devices.
