Three of the 96 questions in this pack
Question 1
Which two statements are correct regarding the PIM DR in a PIM-SM domain? (Choose two.)
Show answer and explanation
Correct answer: C, D. The source DR sends PIM register messages from the source network to the RP; The receiver DR sends PIM join and PIM prune messages from the receiver network toward the RP.
In PIM Sparse Mode, the source DR (Designated Router) on the source network sends PIM register messages toward the RP to announce the source and encapsulate multicast data. The receiver DR on the receiver network sends PIM join and prune messages toward the RP to establish and maintain the multicast tree. These are core responsibilities of DRs at different ends of the multicast path.
Why the other options are wrong
- A. PIM DR election occurs on all links, including point-to-point links; this is not specific to point-to-point links only.
- B. If DR priorities match, the router with the highest IP address is selected as DR, not the lowest.
Question 2
An interface is configured with a behavior aggregate classifier and a multifield classifier. How will the packet be processed when received on this interface?
Show answer and explanation
Correct answer: B. The packet will be processed by the BA classifier first, then the MF classifier.
When both a behavior aggregate (BA) classifier and a multifield (MF) classifier are configured on an interface, the BA classifier is applied first as a coarse classification step. The MF classifier, which performs more granular classification based on multiple fields, is then applied to further refine the classification for packets that pass through the BA classifier.
Why the other options are wrong
- A. The MF classifier does not process packets before the BA classifier.
- C. Packets are not discarded simply because two classifiers are configured; they are processed according to the configured order.
- D. The classifiers will apply their configured changes to packet markings.
Question 3
You are configuring a BGP signaled Layer 2 VPN across your MPLS enabled core network. Your PE-2 device connects to two sites within the same VPN. In this scenario, which statement is correct?
Show answer and explanation
Correct answer: D. By default on PE-2, the remote site IDs are automatically assigned based on the order that you add the interfaces to the site configuration.
When a PE device connects to multiple sites within the same BGP L2VPN, the remote site identifiers are automatically assigned based on the sequence in which interfaces are added to the site configuration. This automatic assignment simplifies configuration management for multi-site deployments.
Why the other options are wrong
- A. A single Layer 2 VPN routing instance can support multiple sites on a PE device; separate instances are not required per site.
- B. The local site ID is not automatically assigned a value of 0, and it does not need to match the total number of attached sites.
- C. Multiple sites on a PE device can share physical interfaces using VLAN or other multiplexing techniques; separate physical interfaces are not mandatory.

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: the Layer 3 and Layer 2 VPN services 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. 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.
