What makes the JNCIP-SP hard
JNCIP-SP is the professional exam on the Juniper service provider track, the one that separates candidates who can configure an MX from candidates who can explain what the routing table did. The current JN0-664 is written against Junos OS 22.3, requires an active JNCIS-SP, and runs 65 questions in 90 minutes. Juniper does not publish domain weightings, but the objectives make the emphasis clear: MPLS and the VPN services built on it are the centre of gravity, with IGP and BGP tuning underneath and multicast and class of service around the edges.
The VPN objectives dominate: Layer 3 VPNs cover VRF tables, route distinguishers and targets and PE-CE routing; Layer 2 VPNs cover BGP and LDP circuits, VPLS and EVPN with its route types and multihoming; MPLS covers LDP and RSVP-TE with fast reroute and segment routing. The IGP objectives cover OSPF and IS-IS at scale, and BGP covers route reflection, confederations and policy. Questions usually show a snippet of configuration or show output and ask what happens next.
This pack has 96 practice questions for the JN0-664 JNCIP-SP exam.
