Service Provider Routing and Switching, Specialist

The Service Provider Routing and Switching, Specialist exam, code JN0-364, leads to the JNCIS-SP credential from Juniper Networks. It is written for network engineers, NOC staff and support engineers who already know basic Junos and now need to show they can work with the routing and switching technologies used in carrier and ISP networks, including OSPF, IS-IS, BGP, MPLS and IPv6. Juniper describes the audience as people with beginner to intermediate Junos knowledge.

What the exam validates

JNCIS-SP is the specialist tier in Juniper’s Service Provider Routing and Switching track. The track runs from the associate level (JNCIA-Junos) through JNCIS-SP, then the professional level (JNCIP-SP) and the expert level (JNCIE-SP). The written exam checks your understanding of routing and switching technology and the related configuration and troubleshooting skills on Junos platforms. It is a knowledge exam, not a live lab, so you are expected to read configurations and command output accurately and choose the right answer rather than build a network under time pressure.

Eligibility and prerequisites

Juniper does not restrict who may sit the exam, but it positions JNCIA-Junos as the foundation for this track and points candidates to it. Confirm on Juniper’s certification page whether JNCIA-Junos must be held before the JNCIS-SP credential is awarded, since certification rules can change. In practice, you should be comfortable with the Junos CLI, configuration hierarchy and commit process, plus general TCP/IP and Ethernet concepts, before starting.

Exam structure and format

Expect roughly 65 multiple choice questions in about 90 minutes, though you should verify both figures with Juniper before booking. The exam is offered in English only. Pass or fail status is available immediately after you finish. Juniper sets the passing score and does not tie it to a simple percentage, so aim to be solid across every topic rather than gambling on a favorite area. Questions are based on Juniper’s recommended training and exam resources, including the Juniper TechLibrary.

Syllabus and subject areas

Juniper publishes the objectives as a high level list and, as far as I could verify, does not publish percentage weights per topic. The main areas include:

• Protocol independent routing, such as routing instances, the routing information base and routing policy application

• OSPF and IS-IS operation in service provider networks

• BGP, including attributes and policy

• MPLS fundamentals, including label switching and signaling

• Segment routing concepts

• IPv6 addressing and routing

• Service provider switching platforms and provider bridging

• Tunneling and high availability topics

Because weights are not published, give each area  attention. Download the current objectives from Juniper before you plan your study, since the list is revised over time. Older Juniper pages used the code JN0-363, so make sure any study material you buy matches JN0-364.

Registration process

Juniper exams are delivered through Pearson VUE. You generally create or sign in to your Juniper certification account, choose the exam, then schedule a test center or online proctored appointment through Pearson VUE and pay the fee. Exact steps, accepted payment methods, ID rules and rescheduling windows are set by Juniper and Pearson VUE, so follow their current instructions rather than a third party summary.

Career value

JNCIS-SP is most relevant if your work involves Juniper MX, PTX or ACX class routers, or any network where MPLS, BGP and IS-IS carry customer traffic. Typical roles include service provider network engineer, NOC engineer, implementation engineer and telecom infrastructure engineer. The credential shows an employer that you can read Junos configurations and reason about carrier routing behavior. It also serves as a stepping stone, since JNCIP-SP builds on the same technologies at greater depth.

Preparing with practice tests

Reading the objectives only gets you so far. The free practice tests on AllExamQuestions.com let you check yourself on topics like BGP path selection, OSPF neighbor states and MPLS forwarding, then review explanations for anything you missed. Use them alongside Juniper’s own documentation and, ideally, hands on time with Junos, and treat your results as a guide to where to study next.
