- The JN0-364 passing score is statistically set for the exam and reported to you; no fixed percentage is published.
- The 70% threshold belongs to separate practice and voucher-assessment pages, not the live JNCIS-SP exam.
- The exam has 65 multiple-choice questions in 90 minutes, delivered through Pearson VUE at a test center or via OnVUE.
- Official domain weights are unpublished, so study all ten objective headings rather than betting on a "heavy" one.
The Short Answer: There Is No Published Cut Score
Candidates searching for the JNCIS-SP passing score usually want a single clean number, such as "you need 70%" or "you need 750 out of 1000." For the Juniper Networks Certified Specialist, Service Provider Routing and Switching (JNCIS-SP) exam, code JN0-364 (Junos OS 25.2), the issuer does not publish that kind of figure. The passing score is statistically set for the individual examination and reported to the candidate. In practical terms, the threshold is determined through the exam's own scoring process, and you learn your result when you finish.
This is a common point of confusion, and it matters because planning around a made-up percentage leads to two bad outcomes: false confidence when you hit that number on an unrelated practice quiz, and false panic when you do not. The better approach is to understand what is and is not known, then prepare for competence across the entire published scope. If you want the broader preparation picture, the JNCIS-SP study guide walks through how to structure that work.
Why Juniper Does Not Publish One Number
Certification programs that set passing scores statistically do so to keep the standard consistent regardless of which version of the exam a candidate sees. The goal is to hold the competence bar steady, not to chase a round percentage. That is why your score report, not a public webpage, is the authoritative source for how you performed.
For candidates, three consequences follow:
- No safe rounding. You cannot decide that you can skip OSPF area types because you are "strong enough elsewhere to make up the difference." Without published weights, you cannot calculate that trade.
- No reliable crowd-sourced figure. Forum posts and third-party landing pages that quote a pass mark are secondhand claims, not issuer facts.
- Preparation should target mastery of the objectives. The scope is the published list of ten objective headings, and your readiness is best measured against it.
If your real worry is difficulty rather than the number, see how hard the JNCIS-SP exam is for a realistic read on what the question set demands.
The 70% Figure You May Have Seen
Several people searching this topic land on a 70% number and assume it is the JNCIS-SP cut score. It is not. That figure appears in two places that are unrelated to the live JN0-364 exam:
| Source | What It Is | Does It Set the JN0-364 Passing Score? |
|---|---|---|
| Official practice-test page for JNCIS-SP | Publishes a 70% practice threshold | No. The page explicitly does not establish the live passing score. |
| Open Learning voucher assessment | 80 minutes, three attempts, 70% threshold to earn voucher eligibility | No. These are voucher-assessment settings, not JN0-364 logistics. |
| Live JN0-364 exam (Pearson VUE) | 65 questions, 90 minutes | Passing score statistically set and reported to the candidate; no fixed percentage published. |
The practical lesson is to avoid importing the practice threshold as your target. Scoring 70% on a practice assessment is a reasonable checkpoint for study progress, but it is not a guarantee of passing, and falling short of it is not a guarantee of failing. Keep the two ideas separate.
Key Takeaway
Use practice scores as a diagnostic for weak domains, not as a pass predictor. The live exam's standard is set independently, so your goal is consistent command of all ten objective areas.
JN0-364 Format and Logistics at a Glance
Understanding the container the score lives in helps you pace yourself. These are the verified facts for the exam as published for Junos OS 25.2:
| Item | Detail |
|---|---|
| Exam code and version | JN0-364, Junos OS 25.2 |
| Number of questions | 65 |
| Time allowed | 90 minutes |
| Format | English-language written multiple-choice exam |
| Delivery | Pearson VUE test center or OnVUE online, subject to local availability, technical checks and candidate ID |
| Published exam fee | $300 per examination plus applicable taxes; no member/nonmember distinction published |
| Prerequisite | Active JNCIA-Junos |
| Credential validity | Three years |
With 65 questions in 90 minutes, you have a little under a minute and a half per item on average. That is enough time to reason through a routing-policy or BGP path-selection question, but not enough to stall on any single one. Because no adaptive-testing behavior or calculator entitlement is established in the reviewed documentation, plan for a standard linear multiple-choice experience and rely on your own subnetting and protocol fluency rather than tools. For the full cost picture, including what is and is not known about final checkout totals, read the JNCIS-SP certification cost breakdown. Eligibility details live in the JNCIS-SP requirements guide.
Scoring Strategy Across the Ten Objective Areas
Juniper lists ten objective headings for JN0-364, but percentage weights are not published. That means no one can honestly tell you which domain carries the most questions, and you should be skeptical of anyone who does. Each heading also splits requirements into two levels: identifying concepts, operation or functionality, and demonstrating configuration, monitoring or troubleshooting knowledge. Both levels are fair game. For a deeper walkthrough of each area, see the JNCIS-SP exam domains guide.
Domain 1: Protocol-Independent Routing
Concepts cover static, aggregate and generated routes, Martian addresses, routing instances including RIB/routing-table groups, load balancing and filter-based forwarding.
- Know how generated routes differ from aggregates and when each is used.
- Be able to read configuration and monitoring output for static routes, load balancing and filter-based forwarding.
Domains 2 and 3: OSPF and IS-IS
Both link-state IGPs are tested at concept and configuration/monitoring/troubleshooting levels.
- OSPF: link-state database, packet types, router ID, adjacencies, DR/BDR, area and router types, LSA types, plus interfaces, neighbors, policy application and troubleshooting tools.
- IS-IS: link-state database, PDUs, TLVs, adjacencies, levels and areas, DIS, metrics, plus interface/adjacency configuration, policy and troubleshooting tools.
- Candidates often know one protocol well and the other thinly; the exam does not reward that imbalance.
Domain 4: BGP
Identify basic operation, message types, attributes, route and path selection, and IBGP versus EBGP behavior and interaction. Configuration knowledge covers groups and peers, additional basic options and routing-policy application.
Domains 5 and 6: Layer 2 Bridging/VLANs and Spanning-Tree
This is where service-provider switching differs from a pure routing mindset.
- Bridging: Junos bridging on service-provider switching platforms, frame processing, virtual switches, provider bridging/Q-in-Q, VLAN port modes and tagging, and IRB.
- Spanning-tree: STP, RSTP, MSTP and VSTP, port roles and states, BPDUs, convergence, plus BPDU, loop and root protection.
Domain 7: MPLS
Covers MPLS terminology, packet header, end-to-end packet flow, labels and the label information base, MPLS and routing tables, RSVP, LDP and segment routing with MPLS. Configuration knowledge spans MPLS forwarding, RSVP-signaled and LDP-signaled LSPs, and shortest-path segment-routing LSPs. Treat this as an introductory-specialist treatment, distinct from professional-level VPN material.
Domains 8, 9 and 10: IPv6, Tunnels and High Availability
- IPv6: static routes, dynamic routing with OSPFv3, IS-IS and BGP, and IPv6-over-IPv4 tunneling.
- Tunnels: IP-tunneling concepts and applications, with GRE configuration, monitoring and troubleshooting.
- High availability: LAGs, graceful restart, GRES, NSB, NSR, BFD and VRRP, at both concept and configuration levels.
What Happens When You Finish
A pass or fail result is available immediately after you complete the exam, though a passing outcome remains provisional pending exam-security validation. Under the published policy, valid results appear in CertMetrics within three business days. Two administrative details can trip candidates up before they ever see a score:
- Name matching. Your legal name must match your government-issued photo and signature identification and your CertMetrics and Pearson VUE accounts.
- Delivery checks. Whether you test at a center or through OnVUE, technical checks and ID verification are part of the process and depend on local availability.
If you are still choosing a testing window, the JNCIS-SP exam dates and scheduling guide covers the practical side.
If You Miss: Retake Rules That Affect Your Plan
Because the passing score is not a number you can target in advance, it helps to know your fallback. The published retake policy is relatively forgiving at the start and then introduces a wait:
| Situation | Rule |
|---|---|
| After the first failure | A repeat attempt may be made without a waiting period |
| After a second or subsequent failure | Wait 14 calendar days; the wait begins the day after the failed attempt |
| After passing | Wait at least 18 months before retaking the same exam |
Each attempt carries the published $300 base fee plus applicable taxes, so a rushed first attempt has a real cost. A better use of the no-wait first retake is not to immediately re-sit but to use your score feedback to target the domains where you were weakest. For perspective on how others fare, see what the data shows in the JNCIS-SP pass rate article; note that no current official pass rate is verified here, so treat any specific figure with caution.
A Domain-Sequenced Plan for Clearing the Bar
Since the cut score is hidden, the most reliable strategy is breadth with depth where it counts. Here is one sequencing approach that follows the dependencies between topics. It is a scheduling suggestion, not an official weighting.
Routing foundations and the link-state IGPs
- Domain 1 first: static, aggregate and generated routes, instances and filter-based forwarding underpin everything later.
- Then OSPF and IS-IS side by side, comparing LSAs against PDUs/TLVs and DR/BDR against DIS.
BGP, then Layer 2
- BGP path selection and policy application, since policy shows up across several domains.
- Bridging, Q-in-Q, IRB, and the four spanning-tree variants with BPDU, loop and root protection.
MPLS, IPv6, tunnels and availability
- MPLS after you are comfortable with IGPs and BGP, since LSP signaling builds on them.
- IPv6 dynamic routing, GRE, then LAG, GR/GRES/NSB/NSR, BFD and VRRP.
Gap closure and full-length timing
- Revisit the domains where concept and configuration/troubleshooting knowledge feel uneven.
- Practice pacing at roughly 65 questions in 90 minutes.
One note on resources: official recommended courses, such as Junos Intermediate Routing, Junos Service Provider Switching and Junos MPLS Fundamentals, are suggested rather than mandatory, and their durations are not exam timers. Independently authored practice questions, including those on our practice test site, support knowledge preparation only; they are not actual or recalled exam questions and do not measure practical competence. For a compact last-pass review, the JNCIS-SP cheat sheet condenses the must-know facts.
Key Takeaway
Aim to explain every objective heading in your own words and to read real Junos output for each. When you can do both across all ten areas, you have prepared in the only way the unpublished score actually rewards.
Finally, remember the credential's lifespan. A pass is valid for three years, and renewal is handled by completing an eligible current exam or qualifying course before expiry, or by earning a higher-level credential in the same track. If you are weighing the payoff of all this effort, the JNCIS-SP ROI analysis and salary guide discuss it, with the caveat that no exact JNCIS-SP salary or credential-caused uplift is verified.

FAQ
The issuer does not publish a fixed percentage. The passing score is statistically set for the individual examination and reported to the candidate. Any specific number you see elsewhere is not an official JN0-364 figure unless it cites an issuer document.
No. The 70% threshold appears on the official practice-test page and on a separate Open Learning voucher assessment. Neither establishes the live exam's passing score, so do not treat 70% as your target or as a guarantee.
The exam has 65 multiple-choice questions and a 90-minute time limit. It is delivered in English through Pearson VUE, either at a test center or online through OnVUE, subject to local availability and technical checks.
That cannot be determined. Juniper lists ten objective headings but does not publish percentage weights, so no largest-weighted domain can be identified. Prepare across all ten, including both concept and configuration/monitoring/troubleshooting requirements.
After the first failure you may retake without a waiting period. After a second or subsequent failure you must wait 14 calendar days, starting the day after the failed attempt. Each attempt carries the published $300 base fee plus applicable taxes.
