About Course

This course contains the use of artificial intelligence.

A received route can be unusable, and a successful MPLS control-plane check does not prove the customer service forwards correctly. These JNCIS-SP JN0-364 practice tests help you trace routing, switching and transport evidence to the relevant Junos decision.

Compare mechanisms at the correct stage

Practise route selection, next-hop resolution, routing instances, policy and OSPF. Work through IS-IS, BGP, provider bridging, spanning tree, MPLS, IPv6, GRE and availability. Scenarios ask which table or route applies, which path is selected and whether a configuration change addresses the actual handoff or failure.

Each option has feedback, with an overall rationale and targeted study tip. A default route toward an attached router, for example, does not override a valid more-specific route. Use these explanations to separate control-plane information, ordinary lookup rules and observed forwarding rather than carry one healthy status across every layer.

The 310 questions include four focused 45-question tests and two 65-question mocks with 90-minute timers. Review the mechanism behind wrong or guessed answers, then use a mixed mock to apply it under different evidence and constraints.

The scope is JN0-364 with the stated Junos OS 25.2 baseline. IP routing foundations are recommended, and official JNCIA-Junos certification prerequisites still apply. The 80% threshold is a course study target, not an official published passing percentage. This independent written resource includes no hosted router lab, official exam items or Juniper endorsement.

What Will You Learn?

  • Separate route eligibility, same-prefix preference and longest-prefix forwarding decisions.
  • Diagnose OSPF and IS-IS adjacency, database and path-selection evidence.
  • Apply BGP policy and attributes after checking route validity and propagation rules.
  • Trace service provider bridge learning, Q-in-Q tag treatment and IRB relationships.
  • Choose spanning-tree roles and protection behavior for the observed event.
  • Interpret MPLS label operations and RSVP, LDP and basic SR-MPLS dependencies.
  • Check IPv6 and GRE inner/outer routes, packet-size budgets and endpoint ownership.
  • Distinguish LAG, GR, GRES, NSR, NSB, BFD and VRRP responsibilities.
