Training for Your Test: Is There Easier Path?

While qualifying for your exam may not seem challenging, the real test lies with the choice of study materials. So, we will be covering the two best paths to help you prepare for your Juniper JN0-348 exam easily:

1. Junos Intermediate Routing (JIR)

The Junos Intermediate Routing (JIR) course is a two-day package that validates the mid-level knowledge of routing implementation in line with the actual exam content outline. This course summarizes the details of protocol-independent routing features, OSPF, IP tunneling, high availability, and load balancing. Also, it combines labs and useful demonstrations to help candidates prove their enthusiasm for routing concepts including the configuration and monitoring of the Junos technologies. What’s more, this course adopts the Juniper Networks vSRX Series Services Gateways to help candidates gain vital hands-on skills and is entirely built around the Junos OS Release 18.2R1.9. As an intermediate-level class, all individuals tasked with monitoring or configuring devices running on the Junos OS would benefit from this training. However, all trainees must first demonstrate an understanding of the TCP/IP suite and the OSI model. Besides, they must complete the introductory course, Junos Operating System, before registering for this training. As you remember, this course only runs for two days so you should never assume that the content will be shallow as it remains a comprehensive training covering all aspects of the Junos Enterprise Routing and Switching. When the training initially begins, the instructors will be eager to introduce the course and leave it at that point. Then, they will focus on protocol-independent routing, open shortest path first, and load balancing with filter-based forwarding to complete the first day of training. On the second and last day, the course will verify the knowledge of border gateway protocol, High Availability, and IP tunneling. This stage focuses on the popular concepts of BFD, VRRP, nonstop active routing, BGP attributes, and GRE tunnels.
