About the JNCIA-DESIGN Exam
Associate-level Juniper network design certification (exam JN0-1103) - customer network design requirements and Juniper product roles, securing the network (zero trust and SASE), network management and reliability (HA, redundancy, automation), campus and branch LAN design (wired and wireless), campus and branch WAN and SD-WAN design, and data center IP fabric design
250 original practice questions for the Juniper Networks Certified Associate - Design (JNCIA-Design, exam JN0-1103). Covers customer network design requirements (the Juniper life-cycle service approach, proposal boundaries, greenfield vs brownfield, top-down design, capacity planning, and the roles of Juniper routers, switches, security, WLAN, SDN, and management solutions), securing the network (defense-in-depth, data center and campus WAN security, zero-trust, and SASE), network management and reliability (high-resiliency design, link and device redundancy, ESI-LAG multihoming, Virtual Chassis, network automation benefits and Juniper automation products, APIs, and management strategies), campus and branch LAN design (LAN best practices, modular design, VLAN and access-control design, EVPN-VXLAN campus architecture, oversubscription, and full WLAN/RF design), campus and branch WAN design (transport types, WAN VPN, HA, and SD-WAN with Session Smart Routing and WAN Assurance), and data center network design (traffic patterns, Clos spine-and-leaf fabric, IP fabric underlay/overlay, routing-protocol selection, and IP fabric scaling). Each question is a realistic network-design scenario with a named designer, a detailed explanation, and per-option rationale.
Who Should Take This Exam?
The JNCIA-Design is designed for network engineers, pre-sales solution engineers, and aspiring network architects who are moving from configuring devices to designing networks. There is no hard prerequisite; a general networking foundation (and ideally JNCIA-Junos) helps, but the exam tests design reasoning — product roles, architecture choices, redundancy, and tradeoffs — rather than hands-on configuration.
Prerequisites: None (JNCIA-Design is the associate entry point of the Juniper Design track)
Typical study time: 4-8 weeks of focused study

Exam Domains & Weights
The JNCIA-DESIGN exam covers 6 domains. Focus your study time based on the weights below — higher-weighted domains have more exam questions.
| Domain | Weight | Practice Qs |
|---|---|---|
| Customer Network Design Requirements | 18% | 44 |
| Securing the Network | 14% | 34 |
| Network Management or Reliability | 18% | 46 |
| Campus and Branch LAN Design | 20% | 50 |
| Campus and Branch WAN Design | 14% | 36 |
| Data Center Network Design | 16% | 40 |
| Total | 100% | 250 |
💡 Study tip: Campus and Branch LAN Design carries the most weight (20%) — start there, and make sure the wireless/RF design half is solid, not just the wired side. Juniper does not publish official percentage weights for JN0-1103, so treat these as study guidance based on objective breadth: every one of the six areas can appear on the exam, so don’t skip the lighter ones like Securing the Network or Campus and Branch WAN.
