- JNCIS-SP (exam JN0-364, Junos OS 25.2) targets service-provider routing and switching on Junos, not enterprise or data center roles.
- The exam has 65 multiple-choice questions in 90 minutes and costs a published $300 plus applicable taxes.
- An active JNCIA-Junos is the stated prerequisite, and the credential stays valid for three years.
- No verified JNCIS-SP-specific salary figure exists, so treat any quoted number with caution.
What the JNCIS-SP Credential Signals to Employers
The Juniper Networks Certified Specialist, Service Provider Routing and Switching (JNCIS-SP) is a specialist-level credential for networking professionals who already have beginner-to-intermediate Junos routing and switching knowledge. Current issuer pages carry HPE Juniper Networking branding, but the credential itself is the same Juniper specialist certification, and hiring managers who know Junos recognize it by the JNCIS-SP name. If you are still orienting yourself, the explainers on what JNCIS-SP is and what JNCIS-SP stands for cover the naming and track structure.
What does the credential actually signal in a hiring conversation? Three things, and they are worth separating from hype:
- Junos fluency at a verified level. Passing JN0-364 means you have demonstrated the ability to identify concepts and show configuration, monitoring or troubleshooting knowledge across ten defined objective areas on Junos OS 25.2.
- Service-provider orientation. The blueprint leans on carrier-style technologies: IS-IS, BGP, MPLS with RSVP, LDP and segment routing, provider bridging (Q-in-Q), and high-availability features like GRES and NSR. Those are the building blocks of backbone and aggregation networks.
- Commitment to the Juniper ecosystem. The credential requires an active JNCIA-Junos first, so it implies a structured progression rather than a one-off exam.
Where JNCIS-SP Roles Appear
Juniper gear has historically been strong in carrier, ISP, cloud-provider and large-enterprise WAN environments. That shapes where the credential is most useful. Without inventing hiring statistics, here are the employer types and role families where Junos service-provider skills are commonly sought:
- Internet service providers and telecom carriers: network engineer, backbone engineer, NOC escalation engineer, provisioning engineer.
- Managed network and managed services companies: operations engineer, implementation engineer, customer-network support engineer.
- Cloud, hosting and colocation providers: network engineer roles touching peering, edge routing and aggregation.
- Systems integrators and VARs: pre-sales or professional-services engineers who deploy Juniper platforms for customers.
- Large enterprises and research networks that run their own MPLS or multi-homed BGP WAN.
Job titles vary widely, and the same work may be called "network engineer," "network operations engineer," or "IP/MPLS engineer." When you search, look past the title and read the requirements section for protocol keywords such as OSPF, IS-IS, BGP, MPLS, LDP, RSVP and Junos.
The Skills Behind Typical Job Listings
Listings that mention JNCIS-SP or Junos tend to bundle a familiar set of expectations. Mapping them to the exam helps you decide how much of your preparation doubles as job preparation.
| Typical listing language | Related JNCIS-SP exam domain |
|---|---|
| "Experience with OSPF and/or IS-IS in large networks" | Domain 2: OSPF; Domain 3: IS-IS |
| "BGP peering, policy and troubleshooting" | Domain 4: BGP |
| "MPLS, LDP, RSVP-TE or segment routing exposure" | Domain 7: MPLS |
| "Layer 2 switching, VLANs, Q-in-Q, spanning tree" | Domain 5: Layer 2 Bridging or VLANs; Domain 6: Spanning-Tree Protocols |
| "IPv6 deployment and dual-stack operations" | Domain 8: IPv6 |
| "GRE tunnels, overlay connectivity" | Domain 9: Tunnels |
| "High availability, redundancy, fast failure detection" | Domain 10: High Availability (LAG, GR, GRES, NSB, NSR, BFD, VRRP) |
| "Static routing, policy-based forwarding, routing instances" | Domain 1: Protocol-Independent Routing |
The overlap is strong, which is the practical argument for the certification: the exam syllabus is not abstract trivia but a reasonable proxy for the daily vocabulary of a service-provider network engineer. For a full breakdown of each objective area, see the complete guide to all 10 JNCIS-SP content areas.
From Exam Domains to Day-to-Day Tasks
Here is how several domains translate into the tasks a Junos engineer might actually do. These are illustrations of the knowledge the objectives describe, not claims about any specific employer's duties.
Domain 1: Protocol-Independent Routing
This is the glue knowledge that shows up everywhere. The objectives cover static, aggregate and generated routes, Martian addresses, routing instances (including RIB/routing-table groups), load balancing and filter-based forwarding.
- On the job: steering specific traffic out a particular next hop, summarizing prefixes, separating customer routing tables.
- Exam depth: concepts for all of it, plus configuration/monitoring/troubleshooting knowledge for static/aggregate/generated routes, load balancing and filter-based forwarding.
Domains 2 and 3: OSPF and IS-IS
Interior gateway protocols are the foundation of carrier cores. OSPF objectives include the link-state database, packet types, router ID, adjacencies, DR/BDR election, area and router types and LSA types. IS-IS objectives cover the link-state database, PDUs, TLVs, adjacencies, levels and areas, DIS and metrics.
- On the job: bringing up adjacencies on new links, applying routing policy, diagnosing why a neighbor will not form.
- Exam depth: concept identification plus configuration, monitoring or troubleshooting knowledge for interfaces, neighbors/adjacencies, policy application and troubleshooting tools.
Domain 4: BGP
BGP is the protocol for customer edge, peering and transit. The blueprint covers basic operation, message types, attributes, route and path selection and IBGP/EBGP interaction, with configuration knowledge for groups, peers, additional basic options and policy application.
- On the job: turning up a peer, tuning path selection through policy, reading the output of a stuck session.
Domain 7: MPLS
The MPLS objectives cover CoS processing on Junos devices, terminology, packet header, end-to-end forwarding, labels and the label information base, MPLS and routing tables, RSVP, LDP and segment routing with MPLS. Configuration knowledge is required for MPLS forwarding, RSVP-signaled LSPs, LDP-signaled LSPs and shortest-path segment-routing LSPs.
- On the job: verifying LSP state, tracing label forwarding hop by hop, understanding why traffic is or is not riding an LSP.
Because the issuer does not publish percentage weights for these ten areas, you cannot responsibly claim that one domain matters most on the exam. For job-readiness purposes, though, IGPs, BGP and MPLS together form the core of most carrier-style engineering work, so weakness there will hurt in interviews regardless of exam weighting.
What We Can and Cannot Say About Pay
Salary is the most-searched question about any certification and the one most prone to made-up numbers. Here is the honest situation:
- No verified, credential-specific salary figure for JNCIS-SP is available in the research behind this site.
- Public job-board pages that surface for "JNCIS" searches aggregate many JNCIS-level roles across tracks, so they do not isolate JNCIS-SP earnings.
- No credential-caused salary uplift has been established. Pay for network engineers depends heavily on location, employer type, seniority, on-call duties and overall skill set.
JNCIS-SP Versus Related Entry Points
Job seekers often ask whether to pursue the service-provider specialist or the enterprise specialist. The decision should follow the jobs you actually want.
| Credential | Orientation | When it fits |
|---|---|---|
| JNCIA-Junos | Associate-level Junos fundamentals | Required prerequisite for JNCIS-SP; useful as a first signal for junior roles |
| JNCIS-SP (JN0-364) | Service-provider routing and switching on Junos | Carrier, ISP, managed-services and MPLS-heavy WAN roles |
| JNCIS-ENT | Enterprise-track specialist | Campus and enterprise switching and routing roles; a separate credential with its own exam |
One caution: older study resources sometimes mix service-provider and enterprise material, or point to earlier exam codes. Make sure anything you use is aligned to JN0-364 and Junos OS 25.2. If you want a candid read on exam difficulty before committing, see how hard the JNCIS-SP exam is.
The Logistics Between You and the Credential
Before the credential can help your job search, you have to earn it. The verified mechanics are:
- Prerequisite: an active JNCIA-Junos. Written exams can be taken in any order, but every prerequisite certification requirement must still be fulfilled and none is waived. Details are in the JNCIS-SP requirements guide.
- Format: 65 multiple-choice questions, 90 minutes, English-language, delivered through Pearson VUE at a test center or via OnVUE online, subject to local availability, technical checks and identification.
- Fee: a published $300 per examination plus applicable taxes, with no member/nonmember distinction published. Regional checkout totals and voucher discounts vary, so confirm at checkout. See the JNCIS-SP certification cost breakdown.
- Passing score: statistically set for the exam and reported to you. It is not the 70% threshold used by separate practice or voucher-assessment pages. More in the passing score article.
- Results: pass/fail is available immediately but remains provisional pending exam-security validation; valid results appear in CertMetrics within three business days under published policy.
- Identity: your legal name must match your government-issued photo ID and your CertMetrics and Pearson VUE accounts, a common cause of test-day trouble.
- Retakes: no waiting period after a first failure; a 14-calendar-day wait after second and subsequent failures, starting the day after the failed attempt; at least 18 months before retaking an exam you have passed.
- Validity and renewal: three years. You renew by completing an eligible current exam or qualifying course before expiry, or by earning a higher-level credential in the same track. An expired credential means restarting the track.

A Job-Aligned Study Sequence
If your goal is employment, not just a pass, sequence your preparation so that each block also strengthens an interview talking point. This is one possible order, assuming you already hold JNCIA-Junos and have some Junos hands-on time. Adjust for your own gaps, and use the JNCIS-SP study guide for deeper resource suggestions.
Routing foundations and IGPs
- Domain 1 first: static, aggregate and generated routes, routing instances, filter-based forwarding.
- Then OSPF and IS-IS: databases, packet/PDU types, adjacencies, DR/DIS behavior, and the show commands you would use to troubleshoot.
BGP and IPv6
- BGP attributes, path selection, IBGP versus EBGP, peer groups and policy application.
- IPv6 static routing, OSPFv3, IS-IS and BGP for IPv6, plus IPv6-over-IPv4 tunneling.
Layer 2 and MPLS
- Bridging, VLANs, IRB, provider bridging, then STP, RSTP, MSTP, VSTP and BPDU/loop/root protection.
- MPLS forwarding, RSVP- and LDP-signaled LSPs and shortest-path segment routing.
Tunnels, high availability and review
- GRE, LAGs, GR, GRES, NSB, NSR, BFD and VRRP.
- Revisit weak areas and drill command output interpretation.
Official recommended preparation includes the Junos Intermediate Routing, Junos Service Provider Switching and Junos MPLS Fundamentals courses. These are recommended rather than mandatory, and course durations are unrelated to the exam timer. Independently written practice material supports knowledge preparation only; it is not issuer-endorsed and is not a substitute for lab time. The JNCIS-SP training overview compares options.
Key Takeaway
Pair every protocol you study with a real command output you can read aloud. In an interview, "here is how I would verify this adjacency" beats reciting definitions, and it is exactly the configuration/monitoring/troubleshooting knowledge the objectives describe.
Presenting the Credential on a Resume and in Interviews
List the credential with its full name, the exam code, and the date earned, for example "Juniper Networks Certified Specialist, Service Provider Routing and Switching (JNCIS-SP)." Include the three-year validity context if the date matters to the employer. Then back it up:
- Name specific technologies from your own work or lab: IS-IS levels, BGP policy, LDP or RSVP LSPs, VRRP with BFD.
- Describe one troubleshooting story end to end, from symptom to command output to fix.
- Be ready for scenario questions that start from the exam vocabulary but go further, such as "why would a neighbor stay stuck in a given state?"
- Avoid claiming practical expertise the written exam does not verify. Say what you have done in a lab or production network, and be candid about the rest.
The exam also does not publish a current pass rate, so do not quote one in interviews or on your profile. If you are curious about what is and is not known, the pass rate analysis explains the data gap, and the one-page cheat sheet is handy for last-minute review before an interview or the exam itself. When you are ready to test your knowledge, try the JNCIS-SP practice test.
Frequently Asked Questions
Not in any universal sense. Employers typically list the certification as preferred or as one acceptable proof of Junos skill within titles like network engineer or NOC engineer. Read the requirements section for protocol and platform keywords rather than searching only on the credential name.
Yes. An active JNCIA-Junos is the stated prerequisite. Exams can be taken in any order, but the prerequisite requirement is not waived, and the prerequisite must be active to count.
No credential-caused salary uplift has been verified, and no JNCIS-SP-specific salary figure is established. Pay depends on location, employer, seniority and broader skills, so compare current postings in your market instead of relying on a single number.
The published fee is $300 per examination plus applicable taxes. The exam has 65 multiple-choice questions and a 90-minute time limit. Final regional checkout totals and any voucher discounts can differ, so confirm at purchase.
It is valid for three years. Before expiry, you can complete an eligible current exam or qualifying course, or earn a higher-level credential in the same track. Renewing a higher-level credential also renews active lower-level credentials in the track. If it expires, you must restart the track.
