Number of JN0-1103 practice questions in our database: 65 (updated: Oct. 18, 2026)
Expected JN0-1103 Exam Topics, as suggested by Juniper :
  • Topic 1: Customer Network Design Requirements: This section of the exam measures skills of Network Design Engineers and covers the foundational aspects of network design. It includes understanding Juniper's life-cycle service approach, defining proposal boundaries, and considerations for both greenfield and brownfield deployments. The section also addresses top-down network design methodologies and capacity planning to ensure scalable and efficient network infrastructures.
  • Topic 2: Securing the Network: This section of the exam measures the skills of Security Architects and covers essential security design principles. It encompasses general security considerations, strategies for securing data centers and campus WANs, and the implementation of zero-trust security models. Additionally, it delves into Secure Access Service Edge (SASE) frameworks to enhance network security posture.
  • Topic 3: Network Management or Reliability: This section of the exam measures skills of Network Operations Center (NOC) Engineers and covers design considerations for ensuring business continuity. Topics include high-resiliency design, implementing link and device-level redundancy, and utilizing technologies like Multihomed Ethernet Segment Identifier Link Aggregation Groups (ESI LAGs) and virtual chassis. The section also explores Juniper SRX firewall redundancy and best practices for campus network redundancy.
  • Topic 4: Campus and Branch LAN Design: This section of the exam measures skills of LAN Infrastructure Specialists and covers considerations for designing wired campus or branch LANs. It addresses best practices in campus LAN design, modular design approaches, subnet and VLAN planning, and access control mechanisms. The section also introduces Ethernet VPN-Virtual Extensible LAN (EVPN-VXLAN) architectures and discusses campus oversubscription ratios and design architectures.
  • Topic 5: Campus and Branch WAN Design: This section of the exam measures skills of WAN Solutions Architects and covers considerations for designing campus or branch WANs. It includes understanding WAN connectivity functions, best practices for WAN design, performance optimization, VPN design, and implementing high availability through active/active and active/passive configurations. The section also explores Software-Defined WAN (SD-WAN) design considerations, devices, assurance models, and intersite connectivity.
  • Topic 6: Data Center Network Design: This section of the exam measures skills of Data Center Network Engineers and covers considerations for general data center network design.

Data center fabric architecture questions were the most detail oriented for me, so I mapped out a few reference designs and their use cases. I passed once I could explain why a given fabric choice fit the application and scale requirements.

Data center fabric questions will ask you to choose between leaf-spine variants and overlay choices based on east-west traffic and scalability needs. I passed by focusing on EVPN/VXLAN, underlay design, ECMP behavior, and sizing exercises in lab topologies.

High availability design came up a lot for campus and WAN, and I had to be clear on when active active makes sense versus active passive. I passed after drilling redundancy patterns and how they affect convergence and complexity.

HA questions often present failure scenarios and ask you to predict which path or node becomes active, so understanding state synchronization and failure modes is essential. A teammate who passed recommended practicing failure-flow diagrams for active/active and active/passive setups and drilling election timers, session mirroring, and split-brain mitigations.

The security and management sections felt practical, especially around designing for reliability and operational visibility. I passed by reviewing common failure domains and what telemetry or tooling actually helps day two operations.

Automation items were tricky because they mix device-level scripting with orchestration, often asking whether a task should be handled on-box or by an off-box tool. Study Junos event and commit scripts, PyEZ and Ansible patterns for idempotency and scale, and I passed after practicing labs plus a short question bank from Pass4Success that helped clarify the practical distinctions.

Capacity planning was trickier than I expected because the questions pushed you to think about growth and oversubscription, not just link speeds. I passed once I started doing quick back of the envelope calculations during practice.

Security items tended to be scenario-based, asking where to place firewalls, how to segment control and data planes, or which mitigation best fits a given threat model. A colleague who passed said hands-on labs with 802.1x, RADIUS, ACLs and control-plane protections made those scenarios straightforward, so focus on deployment trade-offs and common countermeasures.

The JN0-1103 Design, Associate exam leaned heavily on translating customer requirements into workable campus and branch designs, so I spent time practicing how I would justify tradeoffs. I passed after focusing on scenarios instead of memorizing features.

Capacity planning questions often present a traffic matrix and ask you to pick link capacities or oversubscription ratios that meet latency and growth targets. Study traffic aggregation math, oversubscription effects, and basic queuing, and a friend who passed credited Pass4Success for a focused question set that let them cram the core calculations quickly.
