Juniper Data Center, Professional (JNCIP-DC) Sample Questions (Q53-Q58):

NEW QUESTION # 53
Exhibit.

Connections between hosts connected to Leaf-1 and Leaf-2 are not working correctly.

A. Referring to the exhibit, which two configuration changes are required to solve the problem? (Choose two.)
B. Configure the setswitch-options service-id 1 parameter on Leaf-2.
C. Configure the set switch-options vrf-target target:65000:l parameteron Leaf-2.
D. Configure the setswitch-options route-distinguisher i92.168.100.50:i parameter on Leaf-1.
E. Configure the setswitch-options vtep-source-interface irb.0parameter on Leaf-1.

Answer: B,C

Explanation:
* Issue Analysis:
* The problem in the exhibit suggests a mismatch in configuration parameters between Leaf-1 and Leaf-2, leading to communication issues between hosts connected to these leaf devices.
* Configuration Mismatches:
* Service-ID:Leaf-1 has service-id 1 configured, while Leaf-2 does not have this parameter. For consistency and proper operation, the service-id should be the same across both leaf devices.
* VRF Target:Leaf-1 is configured with vrf-target target:65000:1, while Leaf-2 is configured with vrf-target target:65000:2. To allow proper VRF import/export between the two leafs, these should match.
* Corrective Actions:
* C. Configure the set switch-options vrf-target target:65000:1 parameter on Leaf-2:This aligns the VRF targets between the two leaf devices, ensuring they can correctly import and export routes.
* E. Configure the set switch-options service-id 1 parameter on Leaf-2:This ensures that both Leaf-1 and Leaf-2 use the same service ID, which is necessary for consistency in the EVPN- VXLAN setup.
Data Center References:
* Correct configuration of VRF targets and service IDs is critical in EVPN-VXLAN setups to ensure that routes and services are correctly shared and recognized between different devices in the network fabric.

NEW QUESTION # 54
Exhibit.

Referring to the configuration shown in the exhibit, assume that there is no external router present, and that the configuration is fabric-only.
Which two statements are true about the example configuration? (Choose two.)

A. Devices in irb.400 (vlan 400) are not able to communicate directly with devices in routing instance Customer A.
B. VNI 10006is assigned to vlan 800 (irb.800).
C. Devices in routing instance Customer A are able to communicate with devices in routing instance Customer B
D. Devices in irb.400 (vlan 400) and irb.800 (vlan 800) are able to communicate over the fabric.

Answer: A,D

Explanation:
* Understanding the Configuration:
* The exhibit shows configurations for two VRFs (Customer_A and Customer_B) with specific VLANs and VNIs assigned. Each VRF has interfaces (IRBs) associated with particular VLANs.
* Communication Between VLANs and Routing Instances:
* Option B:VLAN 400 (irb.400) is part of Customer_B, and there is no direct connection or routing between Customer_A and Customer_B in the configuration provided. Therefore, devices in irb.400 cannot communicate directly with devices in the Customer_A routing instance.
* Option D:Since irb.400 (VLAN 400) and irb.800 (VLAN 800) are part of the same routing instance (Customer_B), they can communicate over the fabric using VXLAN encapsulation.
Conclusion:
* Option B:Correct-There is no direct communication between devices in irb.400 (Customer_B) and routing instance Customer_A.
* Option D:Correct-Devices in VLAN 400 and VLAN 800 can communicate within the Customer_B routing instance over the fabric.

NEW QUESTION # 55
You are deploying a Clos IP fabric with an oversubscription ratio of 3:1.
In this scenario, which two statements are correct? (Choose two.)

A. The oversubscription ratio remains the same when you remove spine devices.
B. The oversubscription ratio increases when you remove spine devices.
C. The oversubscription ratio decreases when you add spine devices.
D. The oversubscription ratio remains the same when you add spine devices.

Answer: B,C

Explanation:
* Understanding Oversubscription in a Clos Fabric:
* The oversubscription ratio in a Clos IP fabric measures the ratio of the amount of edge (leaf) bandwidth to the core (spine) bandwidth. An oversubscription ratio of 3:1 means that there is three times more edge bandwidth compared to core bandwidth.
* Impact of Adding/Removing Spine Devices:
* Option C:If youremove spine devices, the total available core bandwidth decreases, while the edge bandwidth remains the same. This results in anincrease in the oversubscription ratio because there is now less core bandwidth to handle the same amount of edge traffic.
* Option B:Conversely, if youadd spine devices, the total core bandwidth increases. This decreases the oversubscription ratio because more core bandwidth is available to handle the edge traffic.
Conclusion:
* Option C:Correct-Removing spine devices increases the oversubscription ratio.
* Option B:Correct-Adding spine devices decreases the oversubscription ratio.

NEW QUESTION # 56
You want to convert an MX Series router from a VXLAN Layer 2 gateway to a VXLAN Layer 3 gateway for VNI 100. You have already configured an IRB interface. In this scenario, which command would you use to accomplish this task?

A. set bridge-domains VLAN-100 routing-interface irb.100
B. set vlans VLAN-100 13-interface irb.100
C. set protocols ospf area 0.0.0.0 interface irb.100 passive
D. set protocols isis interface irb.100 passive

Answer: A

Explanation:
* Scenario Overview:
* Converting an MX Series router from a VXLAN Layer 2 gateway to a VXLAN Layer 3 gateway involves transitioning the router's functionality from simply bridging traffic within a VXLAN segment to routing traffic between different segments.
* Key Configuration Requirement:
* IRB (Integrated Routing and Bridging) Interface:An IRB interface allows for both Layer 2 switching and Layer 3 routing. To enable routing for a specific VNI (VXLAN Network Identifier), the IRB interface must be associated with the routing function in the corresponding bridge domain.
* Correct Command:
* C. set bridge-domains VLAN-100 routing-interface irb.100:This command correctly binds the IRB interface to the bridge domain, enabling Layer 3 routing functionality within the VXLAN for VNI 100. This effectively transitions the device from operating solely as a Layer 2 gateway to a Layer 3 gateway.
Data Center References:
* This configuration step is essential when converting a Layer 2 VXLAN gateway to a Layer 3 gateway, enabling the MX Series router to route between VXLAN segments.

NEW QUESTION # 57

A. Unnumbered BGP requires that family inet is configured on each interface.

C. Unnumbered BGP requires that family inet6 is configured on each interface.
D. Unnumbered BGP peering automatically provisions IPv6 peering.

Answer: B,C
