Juniper Service Provider, Professional (JNCIP-SP) Sample Questions (Q60-Q65):

NEW QUESTION # 60
Refer to the exhibit.

Click the Exhibit button.
After adding Customer C to your Layer 3 VPN, you must ensure that PE2 is receiving VPN routes for all customers attached to PE1, as shown in the exhibit.
Which operational command displays this information?

A. show route summary
B. show route table bgp.l3vpn.0
C. show route table customer-c.inet.0
D. show route table inet.0

Answer: B

Explanation:
Understanding the Exhibit and the Problem Statement
The diagram shows a Layer 3 VPN (L3VPN) setup where multiple customers (Customer A, B, and C) are connected across a service provider network using PE (Provider Edge) routers.
PE1 and PE2 exchange VPN routes for all customers using BGP/MPLS Layer 3 VPN (L3VPN) routing.
The question asks how to verify if PE2 is receiving VPN routes for Customer C.
Evaluating the Answer Choices
✅ B. show route table bgp.l3vpn.0 (Correct Answer)
Why?
This command shows all VPN routes stored in the BGP Layer 3 VPN table (bgp.l3vpn.0).
Since PE routers exchange VPN routes using MP-BGP, this table contains the VPN-IPv4 or VPN-IPv6 routes for all customers.
If PE2 is receiving routes from PE1 for Customer C, they will appear in bgp.l3vpn.0.
❌ A. show route table inet.0 (Incorrect)
Why?
The inet.0 table contains global unicast routes for the service provider's network.
VPN routes do not appear here because they are stored in VRF-specific tables.
This command won't help verify VPN route exchange between PE1 and PE2.
❌ C. show route table customer-c.inet.0 (Incorrect)
Why?
The table customer-c.inet.0 represents the VRF routing table for Customer C on the local PE.
It only shows locally installed routes for Customer C but does not confirm if PE2 is receiving routes from PE1.
This command is useful to check local VPN routing but not BGP route propagation.
❌ D. show route summary (Incorrect)
Why?
This command only provides a summary of route counts per protocol (BGP, OSPF, etc.).
It does not display specific VPN routes.
It is useful for general troubleshooting but doesn't confirm VPN route receipt.
Final answer: ✅ show route table bgp.l3vpn.0 (Option B)
Official Juniper Documentation Reference
Junos MPLS VPNs Configuration Guide
Juniper Documentation
"The show route table bgp.l3vpn.0 command displays all VPN-IPv4 routes learned via MP-BGP for Layer 3 VPNs."

NEW QUESTION # 61
Exhibit
user@Rl show configuration interpolated-profile { interpolate {
fill-level [ 50 75 drop-probability [ > }
class-of-service drop-profiles
];
20 60 ];
Which two statements are correct about the class-of-service configuration shown in the exhibit? (Choose two.)

A. The drop probability gradually increases from 20% to 60% as the queue level increases from 50% full to
75% full
B. The drop probability jumps immediately from 20% to 60% when the queue level reaches 75% full.
C. To use this drop profile, you apply it directly to an interface.
D. To use this drop profile, you reference it in a scheduler.

Answer: A,D

Explanation:
class-of-service (CoS) is a feature that allows you to prioritize and manage network traffic based on various criteria, such as application type, user group, or packet loss priority. CoS uses different components to classify, mark, queue, schedule, shape, and drop traffic according to the configured policies.
One of the components of CoS is drop profiles, which define how packets are dropped when a queue is congested. Drop profiles use random early detection (RED) algorithm to drop packets randomly before the queue is full, which helps to avoid global synchronization and improve network performance. Drop profiles can be discrete or interpolated. A discrete drop profile maps a specific fill level of a queue to a specific drop probability. An interpolated drop profile maps a range of fill levels of a queue to a range of drop probabilities and interpolates the values in between.
In the exhibit, we can see that the class-of-service configuration shows an interpolated drop profile with two fill levels (50 and 75) and two drop probabilities (20 and 60). Based on this configuration, we can infer the following statements:
The drop probability jumps immediately from 20% to 60% when the queue level reaches 75% full. This is not correct because the drop profile is interpolated, not discrete. This means that the drop probability gradually increases from 20% to 60% as the queue level increases from 50% full to 75% full. The drop probability for any fill level between 50% and 75% can be calculated by using linear interpolation formula.
The drop probability gradually increases from 20% to 60% as the queue level increases from 50% full to
75% full. This is correct because the drop profile is interpolated and uses linear interpolation formula to calculate the drop probability for any fill level between 50% and 75%. For example, if the fill level is
60%, the drop probability is 28%, which is calculated by using the formula: (60 - 50) / (75 - 50) * (60 -
20) + 20 = 28.
To use this drop profile, you reference it in a scheduler. This is correct because a scheduler is a component of CoS that determines how packets are dequeued from different queues and transmitted on an interface. A scheduler can reference a drop profile by using the random-detect statement under the
[edit class-of-service schedulers] hierarchy level. For example: scheduler test { transmit-rate percent 10; buffer-size percent 10; random-detect test-profile; } To use this drop profile, you apply it directly to an interface. This is not correct because a drop profile cannot be applied directly to an interface. A drop profile can only be referenced by a scheduler, which can be applied to an interface by using the scheduler-map statement under the [edit class-of-service interfaces] hierarchy level. For example: interfaces ge-0/0/0 { unit 0 { scheduler-map test-map; } }

NEW QUESTION # 62

NEW QUESTION # 63
Refer to the exhibit.

Click the Exhibit hutton.
You are configuring an interprovider Option C Layer 3 VPN to connect two customer sites.
Referring to the exhibit, which three statements are correct? (Choose three.)

A. ASBR routers maintain the internal routes from its own AS and the loopback addresses from the other AS PEs.
B. ASBR routers maintain the internal routes from its own AS, the loopback address from the other AS PEs, and the L3VPN routes.
C. P routers maintain the internal routes from its own AS and the loopback address from the other AS PEs.
D. P routers only maintain the internal routes from their own AS.
E. PE routers maintain the internal routes from its own AS, the loopback address from the other AS PEs, and the L3VPN routes.

Answer: A,D,E

Explanation:
Interprovider Option C for Layer 3 VPNs involves the use of Autonomous System Boundary Routers (ASBRs) to exchange labeled VPN-IPv4 routes between different Autonomous Systems (AS). This option requires BGP sessions between ASBRs, and the VPN routes are carried end-to-end using MPLS labels. Here's a detailed analysis of the roles of different routers in this scenario:
1. **ASBR Routers**:
- ASBRs are responsible for exchanging VPN-IPv4 routes between different ASes.
- **A. ASBR routers maintain the internal routes from its own AS and the loopback addresses from the other AS PEs.**
- Correct. ASBRs maintain routes to internal destinations within their own AS, and they also need to know the loopback addresses of PEs in the other AS to set up the BGP sessions and MPLS tunnels.
2. **PE Routers**:
- PE routers are responsible for maintaining VPN routes and label information to forward VPN traffic correctly.
- **B. PE routers maintain the internal routes from its own AS, the loopback address from the other AS PEs, and the L3VPN routes.**
- Correct. PE routers need to maintain:
- Internal routes within their AS for routing.
- Loopback addresses of other AS PEs for establishing MPLS LSPs.
- L3VPN routes to provide end-to-end VPN connectivity.
3. **P Routers**:
- P routers are the core routers that do not participate in BGP VPN routing but forward labeled packets based on MPLS labels.
- **C. P routers only maintain the internal routes from their own AS.**
- Correct. P routers maintain the internal routing information to forward packets within the AS and use MPLS labels for forwarding VPN packets. They do not maintain VPN routes or routes from other ASes.
4. **Incorrect Statements**:
- **D. P routers maintain the internal routes from its own AS and the loopback address from the other AS PEs.**
- Incorrect. P routers do not need to maintain the loopback addresses of other AS PEs. They only maintain internal routing and MPLS label information.
- **E. ASBR routers maintain the internal routes from its own AS, the loopback address from the other AS PEs, and the L3VPN routes.**
- Incorrect. ASBR routers do not maintain L3VPN routes. They exchange labeled VPN-IPv4 routes with other ASBRs and forward them to PE routers.
**Conclusion**:
The correct answers are:
**A. ASBR routers maintain the internal routes from its own AS and the loopback addresses from the other AS PEs.**
**B. PE routers maintain the internal routes from its own AS, the loopback address from the other AS PEs, and the L3VPN routes.**
**C. P routers only maintain the internal routes from their own AS.**

NEW QUESTION # 64
You have an L2VPN connecting two CEs across a provider network. The CEs and provider network are configured with the default MTU setting. You use the ping command from one CE to the other CE with a size of 1500 bytes.
In this scenario, which statement is correct when using the ping command?

A. You expect a silent discard.
B. You expect an echo reply.
C. You expect an ICMP message too long error.
D. You expect the ping results to be fragmented.

Answer: A

Explanation:
Layer 2 VPNs don't support fragmentation in the provider network. It is critical that the provider network supports the largest frame that the CE devices can generate after the MPLS and virtual routing and forwarding (VRF) labels are added by the PE devices. This example leaves the CE devices at the default 1500-byte maximum transmission unit (MTU) while configuring the provider core to support a 4000 byte MTU. This configuration avoids discards by ensuring the CE devices cannot exceed the MTU in the provider's network.
