About the JNCIP-DC Exam
Prove advanced EVPN-VXLAN data center fabrics on Junos (QFX and MX)
The JNCIP-DC (exam JN0-683) is the professional-level certification in Juniper’s Data Center track, verified against Junos OS 23.4. It sits above JNCIS-DC and validates that you can design, configure, monitor, and troubleshoot a modern EVPN-VXLAN data center fabric — Layer 3 (Clos spine-leaf) IP fabrics, VXLAN, EVPN signaling and route types, Data Center Interconnect, and multitenancy with security. Our 250 original practice questions are character-driven Junos scenarios with detailed explanations and per-option rationale.
Note: JN0-683 is the current JNCIP-DC exam code (it replaced the earlier JN0-682). It is a written, multiple-choice exam delivered at Pearson VUE — not a hands-on lab. This guide tracks the current JN0-683 blueprint on Junos OS 23.4.
Who Should Take This Exam?
The JNCIP-DC is designed for experienced data center networking professionals who already hold or are ready for specialist-level Junos knowledge. Two or more years of hands-on Junos data center experience (IP fabrics and EVPN-VXLAN overlays) is recommended.
Typical study time: 8-12 weeks of focused study

Exam Domains & Practice-Question Coverage
The JNCIP-DC exam covers 6 official objective areas. Juniper does not publish percentage weights for this exam, so the practice-question counts below reflect each area’s topic breadth and hands-on depth.
| Domain | Practice Qs |
|---|---|
| Data Center Deployment & Management (ZTP, DHCP relay, telemetry/JTI) | 28 |
| Layer 3 Fabrics (Clos spine-leaf, eBGP underlay, RDMA/RoCEv2 lossless CoS) | 48 |
| VXLAN (VTEP/VNI, encapsulation, control planes vs data plane) | 38 |
| EVPN-VXLAN Signaling (route types 1-5, MP-BGP, CRB vs ERB, symmetric IRB, multicast) | 62 |
| Data Center Interconnect (OTT vs gateway, Layer 2/Layer 3 stretch, stitching, Type-5 DCI) | 42 |
| Data Center Multitenancy & Security (MAC-VRF/IP-VRF, filter-based forwarding, group-based policy) | 32 |
| Total | 250 |
💡 Study tip: EVPN-VXLAN Signaling is by far the largest area — master the five EVPN route types (Type 2 MAC/IP, Type 3 inclusive-multicast/BUM, Type 5 IP-prefix are the most-tested), and be crystal-clear on symmetric vs asymmetric IRB (symmetric uses a shared per-VRF Layer 3 VNI, so a leaf need not host every Layer 2 VNI) and on ERB vs CRB gateway placement.

Juniper Certification Path
Juniper follows: Associate (JNCIA) → Specialist (JNCIS) → Professional (JNCIP) → Expert (JNCIE). For the data center, the path is JNCIA-Junos → JNCIS-DC → JNCIP-DC.

Study Tips
- Draw the EVPN route types — Type 1 (Ethernet A-D: aliasing + mass-withdraw), Type 2 (MAC/IP), Type 3 (inclusive multicast / BUM), Type 4 (Ethernet Segment / DF election), Type 5 (IP prefix). Knowing what each advertises is the single highest-yield skill.
- Symmetric vs asymmetric IRB — symmetric routing uses a shared per-VRF Layer 3 (transit) VNI so only the destination VNI is needed at the egress leaf; asymmetric needs every VNI on the ingress leaf. This is the Junos-preferred model.
- Underlay before overlay — be fluent in the eBGP IP fabric (unique AS per leaf, ECMP load balancing, BFD) and know when to reach for a lossless RDMA/RoCEv2 fabric (PFC + ECN + DCBX).
