JNCIA-JUNOS - Practicum and Exam Preparation

This intense, two-day program is designed to prepare attendees who have previously taken the Introduction to the Junos Operating System (IJOS) course for taking the certification exam while simultaneously gaining insight into real-world applications for the knowledge gained through their coursework.

The course starts off with a day of applying JNCIA-level knowledge and principles to scenarios based on real-world operations with Juniper Networks systems. The second day is a review of JNCIA competencies aligned with the current JNCIA-JUNOS certification exam.

Key topics include user interface options with a heavy focus on the command-line interface (CLI), configuration tasks typically associated with the initial setup of devices, interface configuration basics with configuration examples, secondary system configuration, and the basics of operational monitoring and maintenance of Junos devices. The course then delves into foundational routing knowledge and configuration examples including general routing concepts, routing policy, and firewall filters. Through demonstrations and hands-on labs, students will gain experience in configuring and monitoring the Junos OS and monitoring basic device operations.

An exam voucher is included with this course.

The objectives for this course follow the requirements for the current JNCIA-JUNOS. At the end of this course, the successful student will be able to:

• Identify the concepts and functionality of various fundamental elements of networking
• Identify the concepts, benefits and functionality of the core elements of the Junos OS
• Identify the concepts, operation and functionality of the Junos user interfaces
• Identify the main elements for configuring Junos devices
• Describe how to configure basic components of a Junos device
• Identify methods of monitoring and maintaining Junos devices
• Describe monitoring and maintenance procedures for a Junos device
• Identify basic routing concepts and functionality for Junos devices
• Describe how to configure and monitor basic routing elements for a Junos device
• Identify the concepts and functionality of routing policy and firewall filters on Junos devices
• Describe how to configure and monitor routing policies and firewall filters on a Junos device
• Apply knowledge of Junos operating system configuration, operations, and functionality to real-world scenarios

Target Audience
