Juniper Service Provider, Professional (JNCIP-SP) Sample Questions (Q27-Q32):

NEW QUESTION # 27
In which two ways does OSPF prevent routing loops in multi-area networks? (Choose two.)

  • A. All areas are required to connect to area 0.
  • B. All areas are required to connect as a full mesh.
  • C. The SPF algorithm prunes looped paths within an area.
  • D. The LFA algorithm prunes all looped paths within an area.

Answer: A,C


NEW QUESTION # 28
Exhibit

Referring to the exhibit, PE-1 and PE-2 are getting route updates for VPN-B when neither of them service that VPN Which two actions would optimize this process? (Choose two.)

  • A. Configure the family route-target statement on the PEs.
  • B. Configure the resolution rib bgp.l3vpn.0 resolution-ribs inet.0 statement on the PEs.
  • C. Configure the resolution rib bgp.l3vpn.0 resolution-ribs inet.0 statement on the RR.
  • D. Configure the family route-target statement on the RR.

Answer: C,D

Explanation:
BGP route target filtering can be configured on PE devices or on route reflectors (RRs). Configuring BGP route target filtering on RRs is more efficient and scalable, as it reduces the number of BGP sessions and updates between PE devices. To configure BGP route target filtering on RRs, the following steps are required:
Configure the family route-target statement under the BGP group or neighbor configuration on the RRs. This enables the exchange of the route-target address family between the RRs and their clients (PE devices).
Configure the resolution rib bgp.l3vpn.0 resolution-ribs inet.0 statement under the routing-options configuration on the RRs. This enables the RRs to resolve next hops for VPN routes using the inet.0 routing table.


NEW QUESTION # 29
Based on the configuration contents shown in the exhibit, which statement is true?

  • A. Joins for group 224.7.7.7 are always rejected, regardless of the group count.
  • B. Joins for group 224.7.7.7 are accepted if the group count is less than 25.
  • C. Joins for any group are accepted if the group count value is less than 25.
  • D. Joins for group 224.7.7.7 are rejected if the source address is 192.168.100.10.

Answer: D


NEW QUESTION # 30
Which two statements are correct regarding bootstrap messages that are forwarded within a PIM sparse mode domain? (Choose two.)

  • A. Bootstrap messages are used to notify which router is the PIM RP
  • B. Bootstrap messages distribute RP information dynamically during an RP election.
  • C. Bootstrap messages are forwarded to all routers within a PIM sparse-mode domain.
  • D. Bootstrap messages are forwarded only to routers that explicitly requested the messages within the PIM sparse-mode domain

Answer: B,C

Explanation:
Explanation
Bootstrap messages are PIM messages that are used to distribute rendezvous point (RP) information dynamically during an RP election. Bootstrap messages are sent by bootstrap routers (BSRs), which are routers that are elected to perform the RP discovery function for a PIM sparse-mode domain. Bootstrap messages contain information about candidate RPs and their multicast groups, as well as BSR priority and hash mask length. Bootstrap messages are forwarded to all routers within a PIM sparse-mode domain using hop-by-hop flooding.


NEW QUESTION # 31
You are configuring schedulers to define the class-of-service properties of output queues. You want to control packet drops during periods of congestion.
In this scenario, which CoS configuration parameter would be used to accomplish this task?

  • A. buffer size
  • B. drop profile
  • C. priority
  • D. shaping rate

Answer: B

Explanation:
When configuring Class of Service (CoS) properties for output queues, we need to manage packet drops during periods of congestion. Juniper's CoS framework provides several tools to manage congestion, including drop profiles, buffer sizes, and scheduling mechanisms. Let's break down each option and identify the correct one.
Evaluating the Answer Choices
✅ D. drop profile (Correct Answer)
Why?
A drop profile defines when packets should be dropped based on the queue fill level.
Random Early Detection (RED) or Tail Drop can be used to manage congestion by discarding lower-priority packets first.
Drop profiles are configured under the scheduler to determine how aggressive packet dropping should be during congestion.
Example Juniper Configuration:
schedulers {
best-effort {
drop-profile low-drop;
}
}
drop-profiles {
low-drop {
fill-level 80 drop-probability 50;
}
}
fill-level 80 → When the queue reaches 80% full, packet drops begin.
drop-probability 50 → There is a 50% chance of dropping packets once the threshold is reached.
Official Juniper Documentation Reference:
Junos Class of Service Configuration Guide
"A drop profile determines how packets are discarded based on the queue fill level, allowing control over congestion behavior." Why the Other Options Are Incorrect?
❌ A. buffer size (Incorrect)
Why?
The buffer size determines how many packets the queue can store before congestion occurs.
A larger buffer can delay drops, but it does not actively control dropping behavior.
It affects latency rather than controlling packet drops.
❌ B. priority (Incorrect)
Why?
Priority controls which queue gets serviced first, not how drops are handled.
Higher priority queues are serviced before lower-priority queues, but this does not prevent congestion-related drops.
❌ C. shaping rate (Incorrect)
Why?
Shaping limits the maximum transmission rate of the queue.
While shaping helps reduce congestion, it does not control which packets get dropped during congestion.
Shaping is useful for traffic smoothing, but it does not actively drop packets based on queue fill levels.
Final answer: ✅ D. drop profile
Controls packet drops based on queue congestion.
Defines RED (Random Early Detection) or Tail Drop mechanisms.
Directly influences drop probability as the queue fills up.
Official Juniper Reference:
"Drop profiles are used to manage congestion by determining when and how aggressively packets are dropped based on queue fill level."
