The Juniper JN0-348 is the qualifying exam for the Juniper Networks Certified Internet Specialist - Enterprise Routing and Switching (JNCIS-ENT) certification. It validates IT specialists with intermediate-level knowledge required to implement routing and switching concepts in the Juniper Junos.

2. Junos Enterprise Switching (JEX)

The Junos Enterprise Switching (JEX) is the second course associated with the Junos JN0-348 exam. Like the first class, it is also a two-day training program but with an emphasis on switching knowledge and the relevant configuration skills. It includes in-depth coverage of switching concepts, the Spanning Tree Protocol (STP), virtual LANs, and the features of high availability as well as device security. The training is exclusively centered on the Junos OS Release 20.1R1.11 and features interactive demonstrations alongside hands-on labs to ensure candidates are aptly prepared to face their exams. If you have already acquired the basic routing skills and are now looking to prove your ability to manage or troubleshoot networks, this training is the way forward. All in all, this course targets IT specialists of two groups:

  • Candidates who have already attempted and passed the Introduction to Junos Operating System (IJOS) lessons.
  • Individuals with fundamental knowledge of the OSI model and TCP/IP protocol suite;

Also, you should be proficient in knowing with the relevant Juniper products before registering for this training: Junos OS, EX Series, and Switching. As for the course content, on the 1st day of your training, you can expect the instructors to start by introducing the course before addressing Switching Concepts, Virtual Networks, and the Spanning Tree. The real task, however, lies on the second day, where the trainers will now cover the topics of Port Security, Device Security and Firewall Filters, Virtual Chassis, and High Availability. Here, self-motivated candidates who have already mastered the objectives of MAC Limiting, MACsec, Storm Control, Firewall Filters, and Nonstop Bridging (NSB) among other skills will find it easier to grasp the tested concepts.
