Prepare to operate Juniper based networks and pass the JNCIA-Junos exam.

Gain the foundation required to work with the Junos operating system (OS) and to configure and route a Junos device-based network in this two-day course. You will also prepare to take the Juniper Networks Certified Internet Associate (jncia online training) – Junos (JNCIA-Junos) certification exam.

After a brief overview of the Junos device families, you’ll learn about the key architectural components of the software. Through demonstrations and hands-on labs, you will gain experience in configuring and monitoring the Junos OS and monitoring basic device operations.

You will dive into routing and configuration, beginning with an overview of general routing concepts and covering routing policy and firewall filters and Class of Service (CoS). You’ll also get hands-on experience configuring and monitoring the Junos OS and monitoring basic device operations in JNCIA Online Training.
