Juniper Data Center, Professional (JNCIP-DC) Sample Questions (Q16-Q21):

NEW QUESTION # 16
You manage an IP fabric with an EVPN-VXLAN overlay. You have multiple tenants separated using multiple unique VRF instances. You want to determine the routing information that belongs in each routing instance's routing table.
In this scenario, which property is used for this purpose?

  • A. the VRF target community
  • B. the route distinguisher value
  • C. the VRF table label
  • D. the routing instance type

Answer: B

Explanation:
* Understanding VRF and Routing Instances:
* In an EVPN-VXLAN overlay network, multiple tenants are separated using unique VRF (Virtual Routing and Forwarding) instances. Each VRF instance maintains its own routing table, allowing for isolated routing domains within the same network infrastructure.
* Role of Route Distinguisher:
* Route Distinguisher (RD):The RD is a unique identifier used in MPLS and EVPN environments to distinguish routes belonging to different VRFs. The RD is prepended to the IP address in the route advertisement, ensuring that routes from different tenants remain unique even if they use the same IP address range.
* Correct Property:
* D. the route distinguisher value:This is the correct answer because the RD is crucial in determining which routing information belongs to which VRF instance. It ensures that each VRF' s routing table only contains relevant routes, maintaining isolation between tenants.
Data Center References:
* The RD is a key element in MPLS and EVPN-based multi-tenant environments, ensuring proper routing segregation and isolation for different VRFs within the data center fabric.


NEW QUESTION # 17
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. Devices in irb.400 (vlan 400) and irb.800 (vlan 800) are able to communicate over the fabric.
  • C. Devices in routing instance Customer A are able to communicate with devices in routing instance Customer B
  • D. VNI 10006 is assigned to vlan 800 (irb.800).

Answer: A,B

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 # 18
A local VTEP has two ECMP paths to a remote VTEP
Which two statements are correctwhen load balancing is enabled in this scenario? (Choose two.)

  • A. The source port in the UDP header is used to load balance VXLAN traffic.
  • B. The inner packet fields are not used in the hash for load balancing.
  • C. The destination port in the UDP header is used to load balance VXLAN traffic.
  • D. The inner packet fields are used in the hash for load balancing.

Answer: A,D

Explanation:
* Load Balancing in VXLAN:
* VXLAN uses UDP encapsulation to transport Layer 2 frames over an IP network. For load balancing across Equal-Cost Multi-Path (ECMP) links, various fields in the packet can be used to ensure even distribution of traffic.
* Key Load Balancing Fields:
* C. The source port in the UDP header is used to load balance VXLAN traffic:This is correct.
The source UDP port in the VXLAN packet is typically calculated based on a hash of the inner packet's fields. This makes the source port vary between packets, enabling effective load balancing across multiple paths.
* D. The inner packet fields are used in the hash for load balancing:This is also correct. Fields such as the source and destination IP addresses, source and destination MACaddresses, and possibly even higher-layer protocol information from the inner packet can be used to generate the hash that determines the ECMP path.
* Incorrect Statements:
* A. The inner packet fields are not used in the hash for load balancing:This is incorrect as the inner packet fields are indeed critical for generating the hash used in load balancing.
* B. The destination port in the UDP header is used to load balance VXLAN traffic:This is incorrect because the destination UDP port in VXLAN packets is typically fixed (e.g., port 4789 for VXLAN), and therefore cannot be used for effective load balancing.
Data Center References:
* Effective load balancing in VXLAN is crucial for ensuring high throughput and avoiding congestion on specific links. By using a combination of the source UDP port and inner packet fields, the network can distribute traffic evenly across available paths.


NEW QUESTION # 19
Click the Exhibit button.

Connections between hosts connected to Leaf-1 and Leaf-2 are not working correctly.
Referring to the exhibit, which two configuration changes are required to solve the problem? (Choose two.)

  • A. Configure the set switch-options vtep-source-interface lo0.0 parameter on Leaf-1.
  • B. Configure the set switch-options service-id 1 parameter on Leaf-2.
  • C. Configure the set switch-options route-distinguisher 192.168.100.51:2 parameter on Leaf-1.
  • D. Configure the set switch-options vrf-target target:65000:55 parameter on Leaf-2.

Answer: A,D


NEW QUESTION # 20
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 protocols ospf area 0.0.0.0 interface irb.100 passive
  • C. set protocols isis interface irb.100 passive
  • D. set vlans VLAN-100 13-interface irb.100
