ExploreAbout this exam
JNCIP-ENT - Enterprise Routing and Switching, Professional - is the third of four certifications in the Juniper Enterprise Routing and Switching track, sitting above JNCIA-Junos and JNCIS-ENT and below JNCIE-ENT. It targets experienced networking professionals who already hold advanced knowledge of Junos OS and want to prove depth in advanced routing technologies plus the related platform configuration and troubleshooting skills. The written exam is code JN0-650, delivered by Pearson VUE in English only, and runs 90 minutes over 65 multiple-choice questions, with pass/fail status available immediately after the exam. It is built against Junos OS v25.2. Content spans eight objective areas: Interior Gateway Protocols (OSPFv2, OSPFv3, routing policy), BGP (route selection, next-hop resolution, attributes, communities, NLRI families, policy), IP multicast (ASM versus SSM, RPF, IGMP snooping, PIM sparse mode, rendezvous points, anycast RP, MSDP), advanced Ethernet switching and spanning tree (filter-based VLANs, private VLANs, MVRP, Q-in-Q, L2PT, MSTP/VSTP), Layer 2 authentication and access control (802.1x, MAC RADIUS, captive portal, server fail fallback, guest VLAN), IP telephony features (PoE, LLDP/LLDP-MED, voice VLAN), CoS, and EVPN (route types, VXLAN, multihoming). Juniper recommends Advanced Junos Enterprise Routing and Advanced Junos Enterprise Switching training, plus practice exams and exam prep webinars; these are optional and do not guarantee a pass. JNCIS-ENT is a prerequisite, and the certification is valid for three years. This page is independent study material and is not affiliated with or endorsed by Juniper.
What you'll study
About JNCIP-ENT preparation
What is the exam format and how long do I have?
JN0-650 is 65 multiple-choice questions in 90 minutes, delivered by Pearson VUE. That averages roughly 83 seconds per question, so scenario-based configuration and troubleshooting items need to be read quickly. The exam is provided only in English, and pass/fail status is shown immediately after you finish.
Do I need JNCIS-ENT before booking JNCIP-ENT?
Yes. Juniper lists JNCIS-ENT as the prerequisite certification for JNCIP-ENT. If you have not completed the specialist level, work through JNCIA-Junos and JNCIS-ENT first, because the professional exam assumes you already handle Junos configuration syntax and can move straight to design and troubleshooting reasoning.
Which Junos OS version is the exam based on?
The published exam details list Junos OS v25.2 as the software version. Study command output and feature behavior against that release where possible, particularly for EVPN, CoS and Layer 2 authentication features that change between releases. Older lab guides may show syntax or defaults that no longer match.
How should I order my study across the eight domains?
Build a base in IGPs and BGP first, since route selection and policy reasoning recur in multicast and EVPN questions. Then take multicast and EVPN together, because PIM, RP and VXLAN concepts overlap. Finish with the switching, authentication, telephony and CoS topics, which are more configuration-oriented and quicker to lab.
What training does Juniper recommend?
Juniper recommends the Advanced Junos Enterprise Routing and Advanced Junos Enterprise Switching courses, supplemented by practice exams and exam prep webinars. Juniper states these resources are not required and do not guarantee a pass, so treat them as a structured backbone and add your own hands-on lab time on the specific objective areas.
Which topics do candidates most often underestimate?
Multicast and EVPN tend to be the weakest areas because they are rarely used day to day. Inside multicast, know RPF checks, PIM sparse-mode behavior, RP discovery and election, anycast RP and MSDP scoping. For EVPN, be able to explain route types, VXLAN encapsulation and active multihoming route types rather than just recognizing the names.
How much does the exam cost and what is the retake policy?
Those details are not stated on the certification overview page used for this guide, so confirm the current fee and retake rules with Pearson VUE when you register. Budget for the possibility of a second attempt and schedule early enough that a retake still falls inside your preparation window.
How long is the certification valid, and how do I renew?
Juniper certifications are valid for three years. Plan recertification before the expiry date rather than after, and check the recertification page for the current accepted methods. Because the exam tracks a specific Junos OS release, recertifying also forces you to refresh on features added since your original attempt.
Is this page an official Juniper resource?
No. This is independent study material written for candidates searching for JNCIP-ENT. It is not affiliated with, endorsed by, or sponsored by Juniper Networks or HPE. Always confirm exam code, prerequisites, software version and policies against the official certification page before you register or schedule an exam date.
