What Is JNCIS-SP Certification?

What the JNCIS-SP Credential Actually Is

JNCIS-SP stands for Juniper Networks Certified Specialist, Service Provider Routing and Switching. It is a specialist-level credential in the Juniper service provider routing and switching track, issued under the Juniper Networks certification program (current pages use HPE Juniper Networking branding). The written exam that earns it is coded JN0-364 and is aligned to Junos OS 25.2.

The credential sits above the associate level and below the professional level. In practical terms it says: this person understands how a Junos-based service-provider network moves traffic, and can configure, monitor and troubleshoot the core protocols that carry it. If you want the shorter definitional versions of this topic, see our pages on what JNCIS-SP is and what the acronym stands for.

Who the Specialist Level Is Built For

Juniper positions this credential for networking professionals with beginner-to-intermediate knowledge of Junos routing and switching in a service-provider context. Typical candidates include:

• Network engineers at carriers, ISPs and managed-service providers who operate Junos routers daily
• Junior to mid-level engineers moving from enterprise networking into provider-style designs
• JNCIA-Junos holders who want the next rung on the service provider track
• Pre-sales and support engineers who must speak credibly about OSPF, IS-IS, BGP and MPLS on Juniper platforms

Eligibility is narrow but simple: you need an active JNCIA-Junos. No additional mandatory training hours, employment hours or references are stated on the credential overview, and recommended courses are not mandatory. Details are covered in JNCIS-SP requirements.

Exam Format and Registration Mechanics

Fee and checkout realities

The $300 figure is the published base examination fee, and no member versus non-member pricing is published. Final checkout totals vary by region, tax and any voucher you hold, and those totals are not something this article can state. Do not confuse the exam fee with course charges. For a cost walk-through, see JNCIS-SP certification cost.

Test center or online

You can sit the exam at a Pearson VUE test center or take it remotely through OnVUE. Online delivery depends on local availability, a technical system check and candidate identification. Your legal name must match your government-issued photo and signature ID as well as your CertMetrics and Pearson VUE accounts, so fix any mismatch before booking. Scheduling specifics are covered in JNCIS-SP exam dates.

The passing score question

Candidates often ask for the cut score. The honest answer is that the passing score is set statistically for the individual examination and reported to you afterward. Note that the 70% threshold you may see elsewhere belongs to a separate practice and voucher-assessment context, not to the live exam. More on this in JNCIS-SP passing score.

The Ten Objective Areas, Explained

The official overview publishes ten objective headings. It does not publish percentage weights, so any claim that a particular domain is "the biggest" is guesswork. Treat all ten as testable. A fuller breakdown lives in the JNCIS-SP exam domains guide; here is the practical orientation.

Two Skill Levels Inside Every Objective

The official objectives repeatedly split each domain into two verbs. First you identify concepts, operation or functionality. Then, for most domains, you demonstrate configuration, monitoring or troubleshooting knowledge. That second layer matters because it changes how questions can be asked: not just "what does the designated router do?" but "given this output, why is the adjacency stuck?"

Two details are worth noticing. Domain 1's configuration requirement covers static, aggregate and generated routes, load balancing and filter-based forwarding, which means routing instances and Martian addresses are conceptual rather than configuration items. And segment routing appears in the MPLS domain only as an introductory, shortest-path LSP topic, so do not over-invest in professional-level VPN material for this exam.

Validity, Renewal and Retake Rules

Three-year validity

The credential is valid for three years. Before it expires you can renew by completing an eligible current exam or a specified qualifying course, or by earning a higher-level credential in the same track. A higher-level credential also renews active lower-level credentials in that track and active associate credentials. No universal CEU, CPE or CDU quota is published on the recertification page. If the credential expires, you restart the track.

Retake policy

• After a first failure, you may retry without a waiting period.
• After a second or later 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.

A passing result is provisional until exam-security validation completes; valid results appear in CertMetrics within three business days under published policy. Exams may be taken in any order, but every prerequisite requirement must still be fulfilled, since taking order does not waive eligibility for the credential.

Where the Credential Fits in Hiring

Service-provider routing roles tend to cluster at carriers, ISPs, managed network providers, cloud and hosting operators, and the integrators that build for them. In these environments, OSPF or IS-IS underlay design, BGP policy, MPLS transport and fast-failover tooling like BFD are everyday work, which maps directly onto the ten JNCIS-SP objectives. Employers who run Juniper hardware can use the credential as a screening signal that a candidate knows Junos syntax and service-provider concepts.

Be realistic about earnings claims. Salary aggregators tend to lump all JNCIS-level roles together rather than isolating JNCIS-SP, and no credential-caused pay uplift is verified here. For a discussion of how to evaluate this yourself, read the JNCIS-SP salary guide, the worth-it analysis and our overview of JNCIS-SP jobs.

Service Provider or Enterprise Track?

If you are choosing between JNCIS-SP and its enterprise counterpart, let your daily work decide. The service provider specialist exam emphasizes IS-IS, MPLS with RSVP, LDP and segment routing, provider bridging with Q-in-Q, and carrier-oriented high availability. Enterprise material leans toward other topics. If your network resembles a carrier core or a large aggregation edge, the SP track is the natural fit; if you manage campus, branch and data-center-adjacent networks, look at enterprise. You can start with JNCIA-Junos either way, since it is the shared prerequisite for this specialist exam.

A Domain-Sequenced Preparation Route

Generic study habits matter less than ordering. The sequence below builds dependencies in the right order: underlay first, overlay and transport next, resilience last. Adjust the pace to your experience. For a fuller plan, see the JNCIS-SP study guide, and for a condensed review sheet, the JNCIS-SP cheat sheet.

Official and supplemental resources

Juniper lists recommended courses such as Junos Intermediate Routing, Junos Service Provider Switching and Junos MPLS Fundamentals. These are recommended, not mandatory, and course pages may reference older software releases than the pinned Junos 25.2 exam version, so always check them against the current objectives. Keep in mind that independently written practice questions test knowledge only; they are not recalled exam content and do not measure hands-on competence. Our JNCIS-SP practice test offers original questions for exactly that purpose, and JNCIS-SP training covers course options in more detail.
