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.

What to Know about Exam

The Juniper JN0-348, like many Juniper tests, lasts 90 minutes with a maximum of 65 multiple-choice items. It is an exam that’s offered through the Pearson VUE website and candidates are usually graded based on pass/fail status. Juniper recommends that the willing exam-takers must be well-conversant with the Junos Space Network Director 3.1 and Junos 18.4 before registering for this test.

Test Objectives: What Does It Cover?

In summary, JN0-348 exam is meant to give painstaking coverage of the certification concepts by following the recommended curriculum. And to achieve this, it focuses on the following concepts:

• High Availability;
• Tunnels;
• BGP;
• IS-IS;
• OSPF;
• Protocol Independent Routing;
• Layer 2 Security;
• Spanning Tree;
• Layer 2 Switching or VLANs.

Juniper Enterprise Routing and Switching Certification Path: Excellent Track, but What Does It Entail?

The Juniper Enterprise Routing and Switching certification path allows trainees to showcase their proficiency in working with Juniper Networks technology. This track focuses on routing and switching as part of the overall Juniper Networks enterprise solutions. So, if you are keen to merge the two skills and also demonstrate your troubleshooting flair, this is the way to go.

What Is Juniper Networks Certified Internet Specialist - Enterprise Routing and Switching?

This certification is targeted towards seasoned networking specialists with advanced knowledge of routing and switching implementations within Junos. In general, such a certificate measures the basic knowledge of routing and switching concepts and how they relate to platform configuration and other relevant skills. The prerequisite training for attaining this designation is the mid-level Juniper Networks Certified Internet Associate - Junos certification. Of course, we can’t fail to mention the fact this Juniper certificate is part of the broader Juniper Enterprise Routing and Switching Certification Path which also includes the aforementioned JNCIA-Junos certification.

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.

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:

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

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.
