Duration:   1 Day
Price:   $950.00
Test Level:   1
Certifications:   JNCIA-JUNOS
Exams:   JN0-101

Course Overview

This one-day course is designed to provide students with information about troubleshooting SRX Series hardware, the Junos operating system, and more obscure problems like packet loss and latency, interior gateway protocols, BGP, routing policy, multicast, and class of service. Students will gain experience in monitoring and troubleshooting these topics through demonstration as well as hands-on labs. The course exposes students to common troubleshooting commands and tools used to troubleshoot various intermediate to advanced issues.

This course uses Juniper Networks SRX Series Services Gateways for the hands-on component, but the lab environment does not preclude the course from being applicable to other Juniper hardware platforms running the Junos OS. This course is based on Junos OS Release 12.1R5.5.
