What Is A JNCIS-SP?

What a JNCIS-SP Actually Is

The JNCIS-SP is the Juniper Networks Certified Specialist, Service Provider Routing and Switching credential. It sits in Juniper's service-provider certification track, now presented under HPE Juniper Networking branding, and it validates that you understand the core routing, switching and transport technologies that carrier and service-provider networks run on Junos OS. It is aimed at networking professionals with beginner-to-intermediate Junos routing and switching knowledge.

The word "specialist" matters. This is not an entry-level exam, and it is not the professional tier that follows it. It confirms that you can explain how the key protocols behave and that you can configure, monitor and troubleshoot a defined set of them. If you are looking for a shorter definition of the acronym itself, see our explainer on what JNCIS-SP stands for; this article goes deeper into what the credential covers and how it works in practice.

Where It Fits in the Juniper Track

Juniper's certification tracks are layered. The associate-level JNCIA-Junos is the foundation, and the JNCIS-SP builds directly on it: an active JNCIA-Junos is the stated prerequisite. The certification program FAQ allows written exams to be taken in any order, but every prerequisite certification requirement must still be fulfilled before the credential is awarded, and none is waived. Taking the exam early does not make you eligible for the credential early.

No additional mandatory education, employment hours, training hours or references are stated on the credential overview. Recommended training exists, but it is not required. For the full eligibility picture, read our guide to JNCIS-SP requirements and prerequisites.

The JN0-364 Exam at a Glance

Ninety minutes for 65 questions works out to a little under 1 minute 25 seconds per question on average. That is comfortable for recall-style items and tight for scenario questions that ask you to read configuration output or a show command and decide what is wrong. Pass/fail is available immediately after the exam, subject to exam-security validation, and valid results appear in CertMetrics within three business days under the published policy.

The Ten Objective Areas

The official exam objectives list ten headings. Juniper does not publish percentage weights for them, so any claim that one area makes up a specific share of the exam is not issuer-backed. The practical consequence: study all ten. Our complete guide to all 10 JNCIS-SP content areas expands on each one; here is the working summary.

Two Levels of Skill: Identify vs. Configure/Monitor/Troubleshoot

Each objective heading is written at two levels, and the distinction is one of the most useful things to understand about the blueprint. The first level asks you to identify concepts, operation or functionality: what an LSA type carries, what a DIS does, how a BGP attribute influences path selection. The second asks you to demonstrate configuration, monitoring or troubleshooting knowledge: reading a configuration hierarchy, interpreting show-command output, and spotting why an adjacency won't form.

Not every topic is tested at both levels. For example, Martian addresses and RIB groups appear in the identify list for Domain 1, while the configuration list names static, aggregate and generated routes, load balancing and filter-based forwarding. Likewise, in Domain 7 the identify list covers RSVP, LDP and segment routing, while the published configuration list covers MPLS forwarding, LDP-signaled LSPs and shortest-path segment-routing LSPs (the RSVP-signaled bullet in the source is incomplete, so treat the RSVP configuration scope as something to confirm in the official objectives).

Registration, Fees and Retakes

Cost and booking

The published base fee is $300 USD per examination plus applicable taxes, with no member or nonmember distinction published. Final regional checkout totals, taxes and candidate-specific voucher discounts vary and are not something this article can state. Course charges are separate from the exam fee and should not be added to it in your budget math. For a fuller picture, see the JNCIS-SP certification cost breakdown.

You book through Pearson VUE, either at a test center or through OnVUE online proctoring where available. Your legal name must match your government-issued photo and signature identification, and your CertMetrics and Pearson VUE accounts must match too. Mismatches are a common, avoidable reason for being turned away. Scheduling specifics are covered in our exam dates and scheduling guide.

Retake rules

• After a first failure, you may retake without a waiting period.
• After a second or subsequent failure, you must wait 14 calendar days, counted from the day after the failed attempt.
• After passing, you must wait at least 18 months before retaking the same exam.

Who Benefits From the Credential

The domain list tells you who this exam is built for. OSPF, IS-IS and BGP as the routing core, MPLS with RSVP, LDP and segment routing as the transport layer, Q-in-Q and provider bridging for Ethernet service delivery, and BFD, GR and NSR for resilience: this is the toolkit of carriers, ISPs, managed-service providers, data-center interconnect teams and the vendors and integrators that support them. Roles that commonly line up with it include network engineer, backbone or core engineer, network operations and NOC escalation roles, and pre-sales or systems engineering positions at Juniper partners.

Be realistic about career claims. There is no verified salary figure that isolates JNCIS-SP holders, and no verified credential-caused pay uplift. Salary aggregators tend to lump together all JNCIS roles. For a grounded discussion, see our JNCIS-SP salary guide, the JNCIS-SP jobs overview, and the ROI analysis.

A Domain-Ordered Study Sequence

Because the domains build on each other, order matters more than hours. Here is one sequence tied to the actual objective list, assuming you already hold an active JNCIA-Junos.

MPLS comes late deliberately: it depends on a working IGP, and segment routing in this exam is introductory and tied to shortest-path LSPs. For the full methodology, see our JNCIS-SP study guide and the one-page cheat sheet. When you are ready to test yourself, try the JNCIS-SP practice tests, which are independently written knowledge-preparation material rather than recalled or official exam questions.

JNCIS-SP vs. JNCIS-ENT

Candidates often ask which specialist exam to take. Both sit one tier above JNCIA-Junos, and both assume you know the Junos fundamentals. The difference is orientation: the service-provider specialist emphasizes carrier-style transport and scale, which is why MPLS, IS-IS, provider bridging/Q-in-Q and segment routing appear in its objectives. The enterprise specialist targets enterprise campus and branch design. If your day job or target employer runs a provider backbone, JNCIS-SP is the closer match; if you work in enterprise LAN and WAN, the enterprise track will usually fit better. Check the official objectives for each before committing, because the overlap in routing and switching fundamentals is real but not complete.

Validity and Renewal

The credential is valid for three years. To renew, you complete an eligible current exam or a specified qualifying course before expiry, or you achieve a higher-level credential in the same track. Earning a higher-level credential renews active lower-level credentials in that track as well as active associate credentials. No universal CEU/CPE quota is published on the reviewed recertification page. If the credential expires, you restart the track, which includes re-establishing the prerequisite chain. Plan your renewal well before the three-year mark rather than treating it as an afterthought.
