About the JNCIS-SP Exam
Specialist-level Juniper service provider certification on Junos OS - protocol-independent routing (static, aggregate, generated routes, RIB groups, load balancing, filter-based forwarding), OSPF and IS-IS link-state routing, BGP path selection and iBGP/eBGP, Layer 2 bridging and VLANs (provider bridging / Q-in-Q, IRB), spanning-tree (STP/RSTP/MSTP/VSTP), MPLS with RSVP, LDP and segment-routing LSPs, IPv6 (OSPFv3, IS-IS, BGP inet6, v6-over-v4 tunneling), GRE/IP tunnels, and high availability (LAG, GR/GRES/NSR/NSB, BFD, VRRP)
250 original practice questions for the Juniper Networks Certified Specialist Service Provider Routing and Switching (JNCIS-SP, exam JN0-364). Covers protocol-independent routing (static, aggregate, and generated routes, Martian addresses, routing instances and RIB groups, per-flow vs per-packet load balancing, and filter-based forwarding), OSPF (link-state database, packet and LSA types, DR/BDR election, area types including stub/totally-stubby/NSSA, and router types), IS-IS (PDUs and TLVs, NET and system-ID addressing, Level 1/Level 2 areas, DIS election, and narrow vs wide metrics), BGP (message types, attributes and the Junos path-selection process, iBGP vs eBGP, and next-hop-self as a policy action), Layer 2 bridging and VLANs (frame processing, virtual switches, provider bridging and Q-in-Q with 802.1ad, access/trunk port modes, 802.1Q tagging, and Integrated Routing and Bridging), spanning-tree protocols (STP/RSTP/MSTP/VSTP, port roles and states, BPDU protection, loop protection, and root protect), MPLS (labels and the label information base, inet.3 and mpls.0, RSVP-signaled and LDP-signaled LSPs, and segment routing / SPRING), IPv6 (addressing, OSPFv3, IS-IS and BGP for IPv6, and IPv6-over-IPv4 tunneling), GRE and IP tunnels (gr- interfaces, keepalives, MTU and recursive-routing considerations), and high availability (aggregated Ethernet LAGs, graceful restart, GRES, nonstop active routing and nonstop bridging, BFD, and VRRP). Each question is a realistic Junos OS service-provider scenario on MX, PTX, ACX, and EX platforms with a named character, a detailed explanation, and per-option rationale.
Who Should Take This Exam?
The JNCIS-SP is designed for network engineers who build and operate Juniper MX, PTX, and ACX service-provider and carrier networks. JNCIA-Junos (the Junos Associate) is the recommended prerequisite, and hands-on Junos CLI experience with OSPF, IS-IS, BGP, and MPLS helps a lot.
Prerequisites: JNCIA-Junos recommended (no hard prerequisite)
Typical study time: 6-10 weeks of focused study

Exam Domains & Weights
The JNCIS-SP exam covers 10 domains. Focus your study time based on the weights below — higher-weighted domains have more exam questions.
| Domain | Weight | Practice Qs |
|---|---|---|
| Protocol-Independent Routing | 9% | 23 |
| High Availability | 13% | 26 |
| Open Shortest Path First (OSPF) | 12% | 26 |
| Intermediate System to Intermediate System (IS-IS) | 12% | 26 |
| Border Gateway Protocol (BGP) | 9% | 23 |
| Layer 2 Bridging and VLANs | 14% | 30 |
| Spanning-Tree Protocols | 8% | 22 |
| Multiprotocol Label Switching (MPLS) | 14% | 30 |
| IPv6 | 5% | 22 |
| Tunnels | 4% | 22 |
| Total | 100% | 250 |
💡 Study tip: Layer 2 Bridging & VLANs and MPLS (14% each), plus High Availability (13%), are the three heaviest areas — start there, and make sure you can configure RSVP- and LDP-signalled LSPs on Junos. Juniper does not publish official percentage weights for JNCIS-SP, so treat these as study guidance based on objective breadth: give every domain real time, because exam questions can come from any of the ten.
