Course Description
Course Overview
This five-day course brings together the three-day Introduction to the Junos Operating System (IJOS) course with a two-day Practicum and JNCIA-JUNOS certification exam preparation with the opportunity to take the exam during the last two hours of the course.
IJOS
The three-day IJOS course provides students with the foundational knowledge required to work with the Junos operating system and to configure Junos devices. The course provides a brief overview of the Junos device families and discusses the key architectural components of the software. 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.
JNCIA 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. You will have the opportunity to take the exam during the last two hours of this day.
Bundled Bonuses
Students that register for this version of the course will also be granted the following:
- Free retake of the IJOS course in any available class within 6 months of first attendance
- Free voucher to take the JNCIA-JUNOS certification exam
- Free retake voucher if you do not pass on the first attempt
