- Juniper sets the JN0-664 passing score statistically per exam and reports it to the candidate; no fixed percentage is published.
- The 70% figure on Juniper's practice and voucher assessments does not establish the live exam's pass mark.
- JN0-664 has 65 multiple-choice questions in 90 minutes, delivered through Pearson VUE.
- No wait applies after a first failure; second and later failures require 14 calendar days.
The Short Answer: There Is No Published Cutoff
If you searched for a single number, here is the honest answer: Juniper does not publish a fixed percentage or scaled score that you must hit on the JNCIP-SP written exam. The credential in question is the Juniper Networks Certified Professional, Service Provider Routing and Switching (JNCIP-SP), exam code JN0-664, built on Junos OS 22.3. For this exam, the passing score is set statistically for the individual exam and reported to the candidate afterward.
That sounds frustrating, but it has practical consequences for how you prepare. Instead of aiming for a magic percentage, you aim for broad, configuration-level command of all seven published objective areas. This article explains what is and is not known about scoring, how to avoid being misled by figures from other sources, and how to build a preparation plan that does not depend on guessing the cutoff. For the wider picture of how demanding the exam is, see our guide on how hard the JNCIP-SP exam is.
How the Passing Score Is Set
Juniper's published position is that the passing score for each written exam is established statistically and reported to the candidate. Several things follow from that wording, and several things do not.
What is verified
- The passing score is specific to the individual exam.
- It is reported to the candidate after the attempt.
- It is not a single program-wide percentage applied to every Juniper exam.
What is not published
- The exact raw or scaled cutoff for JN0-664.
- Percentage weights for any of the seven objective areas.
- Whether individual questions carry unequal value.
- Whether the exam is adaptive, or whether an exam-specific calculator entitlement exists. Neither was established in the sources reviewed.
Keeping these unknowns unknown matters. Many third-party pages fill the gap with confident cutoffs, domain percentages, or claims about simulations and drag-and-drop items. The issuer's credential overview supports none of those claims, so they should not shape your preparation. Real figures on pass rates are similarly thin; our write-up of the JNCIP-SP pass rate explains what can and cannot be said responsibly.
Why 70% Is the Wrong Number
The most common source of confusion is the 70% figure. Juniper's learning portal does list a 70% threshold, but it belongs to other products:
| Item | What it is | Does it set the live exam pass mark? |
|---|---|---|
| JNCIP-SP practice test page | Practice assessment listing a 70% practice threshold | No. The page itself states it does not establish the live passing score. |
| JNCIP-SP Voucher Assessment Test | 80 minutes, three attempts, 70% to earn a discount voucher | No. This is a discount mechanism, not the certification exam. |
| JN0-664 written exam | 65 questions, 90 minutes, Pearson VUE | Governs certification; score set statistically and reported to the candidate. |
Two further cautions. First, the voucher assessment's 80-minute timer and three-attempt limit are not the real exam's duration or retake policy. Second, the voucher's 30-day use window is a promotional detail and has nothing to do with how long your certification stays valid. Mixing these up is one of the easiest ways to misjudge the real exam.

Ninety minutes for 65 questions works out to a little under 1 minute 25 seconds per question on average. That is tight for scenario-style items that ask you to reason about a configuration or monitoring output. Pace matters, and the pacing is part of what "passing" demands even though the cutoff itself is unpublished. Fee mechanics are covered in detail in our JNCIP-SP certification cost breakdown.
Seven Objective Areas That Decide Your Result
The pinned objectives list seven headings and, importantly, no percentage weights. You cannot responsibly assume that one area is "worth" more than another, so the safe strategy is competence across all of them. Each area combines concept-level knowledge with scenario-based configuration or monitoring knowledge. All of it is tested as a written exam, not as a hands-on lab. JN0-664 is not the expert-level practical exam. For a deeper walkthrough, see the complete guide to all 7 content areas.
Domain 1: OSPF
OSPFv2 and OSPFv3 operation, plus scenario configuration and monitoring.
- Area types and operations, and LSA flooding across multiple areas
- DR/BDR operation, the SPF algorithm, and metrics including external metric types
- Route summarization and restriction, virtual links, and OSPFv2 versus OSPFv3
- Single-area and multi-area configuration, including OSPF routing policy
Domain 2: IS-IS
Levels, areas and the mechanics that make IS-IS behave differently from OSPF.
- Areas/levels, designated intermediate system operation, the SPF algorithm
- Wide metrics, route summarization and route leaking
- Flooding of link-state PDUs across a multi-area network
- Single-area and multi-area configuration, including IS-IS routing policy
Domain 3: BGP
Both the operation of BGP and policy-driven scenarios.
- Route-selection process, next-hop resolution, attributes, communities and regular expressions
- Multipath, multihop, load balancing, advanced options, route damping and flowspec
- Multiprotocol BGP and BGP scaling through route reflection
- Scenario configuration and monitoring, including BGP routing policy
Domain 4: Class of Service (CoS)
A frequently reported weak spot among learners, because the pieces must be understood as a pipeline.
- CoS processing on Junos OS devices and header fields
- Forwarding classes, classification and packet loss priority
- Policers, schedulers, drop profiles and rewrite rules
- Scenario configuration and monitoring
Domain 5: IP Multicast
Another area learners commonly report struggling with.
- Multicast addressing, traffic flow, ASM versus SSM, and RPF operation
- IGMP, rendezvous-point concept, discovery and election, Anycast RP
- SSM requirements, benefits and address ranges
- PIM dense and sparse mode configuration and monitoring, including multicast routing policy
Domain 6: Layer 3 VPNs
Control-plane and data-plane flow, and the constructs that glue a provider VPN together.
- Full-mesh versus hub-and-spoke, VPN-IPv4 addressing, route distinguishers and route targets
- Route distribution, site of origin, sham links and VRF table-label
- Next-generation multicast VPNs and their control/data flow, scaling, IPv6 Layer 3 VPNs, Internet access options
- Junos OS support for carrier-of-carriers and inter-provider VPN models
Domain 7: Layer 2 VPNs
Four distinct technology branches that candidates must keep separate.
- BGP Layer 2 VPNs: forwarding tables, connection mapping, NLRI, route distinguishers and targets
- LDP Layer 2 circuits: virtual-circuit label, autodiscovery, Layer 2 interworking
- VPLS: BGP and LDP label distribution, route targets, multihoming, site IDs
- EVPN: MAC learning/distribution, multihoming, BGP EVPN label distribution. Scenarios include configuration, monitoring and troubleshooting.
Because no weights are published, a narrow strength cannot compensate for a blind spot you cannot size. Our JNCIP-SP study guide builds on this same seven-area structure.
Studying for an Unknown Cutoff
Since the target number is hidden, aim for a defensible standard: you should be able to explain why a configuration works and predict what the monitoring output will show. A sensible sequencing, tied to how the topics depend on each other, looks like this:
IGPs: OSPF and IS-IS
- Do these first; BGP, VPNs and MPLS-based services all assume a healthy IGP.
- Compare area/level behavior, metrics, summarization and leaking side by side.
BGP and routing policy
- Master route selection and next-hop resolution before touching communities and flowspec.
- Practice policy logic until you can read it quickly under time pressure.
CoS and multicast
- Walk the CoS pipeline end to end: classification, scheduling, drop behavior, rewrite.
- Trace RPF checks and RP election by hand for several topologies.
Layer 3 and Layer 2 VPNs
- Draw the route-target and route-distinguisher flow for full-mesh and hub-and-spoke.
- Build a one-page matrix separating BGP L2VPN, L2 circuits, VPLS and EVPN.
Optional recommended training named in the overview includes Advanced Junos Service Provider Routing, Junos Layer 2 VPNs and Junos Layer 3 VPNs. Attending does not guarantee a pass, and course hours are not exam duration. For a condensed last-mile review, the JNCIP-SP cheat sheet is a handy companion, and you can drill scenario-style material on our JNCIP-SP practice test platform. Those questions are independently written for knowledge preparation, are not issuer questions, and do not measure hands-on competence.
Key Takeaway
Do not time your exam booking around a rumored percentage. Time it around consistent, explained accuracy across all seven areas, with extra review on CoS, multicast, IS-IS and VPLS if those are your weak points.
Results, Security Validation and Retakes
A passing result on the day is provisional. Immediate results remain subject to security validation, and under the published policy valid results appear in CertMetrics within three business days. Plan your announcements and any job-related deadlines accordingly.
Retake rules for the written exam
- After a first failure: no mandatory wait.
- After a second or subsequent failure: wait 14 calendar days, counted from the day after the failed attempt.
- After passing: you must wait at least 18 months before repeating the same passed examination.
Each attempt carries the full $400 USD base fee plus applicable taxes, so a failed attempt is a real cost. That is a good argument for using your reported score feedback to target remediation rather than rebooking immediately. The score report is the one place Juniper tells you where you stood against the passing score.
Eligibility and Booking Mechanics
Passing the exam is not the only gate to holding the credential. The prerequisite is an active JNCIS-SP. JNCIA-Junos is not the direct prerequisite, and specialist objectives are not the professional syllabus. Written exams may be taken in any order, but every prerequisite certification requirement must still be fulfilled; none is waived, and exam-taking order does not equal eligibility to receive the credential. No additional mandatory education, work-experience hours or references are stated. The full path is explained in our JNCIP-SP requirements guide.
On exam day, the legal name on your Pearson VUE and CertMetrics accounts must match your government-issued photo and signature ID. OnVUE remote delivery adds technical checks to the identity step. For test-window planning, see JNCIP-SP exam dates and scheduling.
Once certified, the credential is valid for three years. You can renew by passing an eligible current exam, completing a specified qualifying course before expiry, or earning a higher-level certification in the same track. A lapsed certification means restarting the track. If you are weighing whether the effort pays off, our ROI analysis and salary guide explain why no JNCIP-SP-specific pay figure is quoted here: none could be verified.
Frequently Asked Questions
Juniper does not publish a fixed percentage. The passing score for JN0-664 is set statistically for the individual exam and reported to the candidate. Any site quoting an exact cutoff should cite Juniper directly.
No. The 70% figure appears on Juniper's practice test page and the voucher assessment, and the practice page explicitly says it does not establish the live passing score. The voucher assessment (80 minutes, three attempts) is a discount mechanism, not the certification exam.
JN0-664 has 65 multiple-choice questions and a 90-minute time limit, delivered in English through Pearson VUE at a test center or via OnVUE remote proctoring, subject to availability.
There is no wait after a first failure. After a second or later failure you must wait 14 calendar days, starting the day after the failed attempt. Each attempt requires paying the exam fee again.
The issuer lists seven objective headings but publishes no percentage weights, so you should not assume any domain counts for more. Prepare for all seven: OSPF, IS-IS, BGP, CoS, IP Multicast, Layer 3 VPNs and Layer 2 VPNs.
