Juniper Data Center, Professional (JNCIP-DC) Sample Questions (Q48-Q53):

NEW QUESTION # 48
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 route distinguisher value
B. the routing instance type
C. the VRF table label
D. the VRF target community

Answer: A

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 # 49
Exhibit.

Referring to the exhibit, why is the active source field blank for the entry that uses the 00:0c:29:e8:b7:39 MAC address?

A. The host for this entry is locally connected to leaf1.
B. This entry is associated with a multicast EVPN route.
C. The EVPN route for this host does not have a valid next hop.
D. The ARP lookup for this host has failed.

Answer: A

NEW QUESTION # 50
Exhibit.

A VXLAN tunnel has been created between leaf1and Ieaf2 in your data center. Referring to the exhibit, which statement is correct?

A. Traffic sent from server1to server2 will be dropped on Ieaf2.
B. Traffic sent from server1to server2 will be tagged with VLAN ID 100 on Ieaf2 and forwarded to server2.
C. Traffic sent from server1to server2 will be tagged with VLAN ID 200 on Ieaf2 and forwarded to server2.
D. Traffic sent from server1to server2 will be dropped on leaf1.

Answer: C

Explanation:
* Understanding VXLAN Tunneling:
* VXLAN (Virtual Extensible LAN) is a network virtualization technology that addresses the scalability issues associated with traditional VLANs. VXLAN encapsulates Ethernet frames in UDP, allowing Layer 2 connectivity to extend across Layer 3 networks.
* Each VXLAN network is identified by a unique VXLAN Network Identifier (VNI). In this exhibit, we have two VNIs, 5100 and 5200, assigned to the VXLAN tunnels between leaf1 and leaf2.
* Network Setup Details:
* Leaf1:Connected to Server1 with VLAN ID 100 and associated with VNI 5100.
* Leaf2:Connected to Server2 with VLAN ID 200 and associated with VNI 5200.
* Spine:Acts as the interconnect between leaf switches.
* Traffic Flow Analysis:
* When traffic is sent from Server1 to Server2, it is initially tagged with VLAN ID 100 on leaf1.
* The traffic is encapsulated into a VXLAN packet with VNI 5100 on leaf1.
* The packet is then sent across the network (via the spine) to leaf2.
* On leaf2, the VXLAN header is removed, and the original Ethernet frame is decapsulated.
* Leaf2 will then associate this traffic with VLAN ID 200 before forwarding it to Server2.
* Correct Interpretation of the Exhibit:
* The traffic originating from Server1, which is tagged with VLAN ID 100, will be encapsulated into VXLAN and transmitted to leaf2.
* Upon arrival at leaf2, it will be decapsulated, and since it is associated with VNI 5200 on leaf2, the traffic will be retagged with VLAN ID 200.
* Therefore, the traffic will reach Server2 tagged with VLAN ID 200, which matches the network configuration shown in the exhibit.
* Data Center References:
* This configuration is typical in data centers using VXLAN for network virtualization. It allows isolated Layer 2 segments (VLANs) to be stretched across Layer 3 boundaries while maintaining distinct VLAN IDs at each site.
* This approach is efficient for scaling large data center networks while avoiding VLAN ID exhaustion and enabling easier segmentation.
In summary, the correct behavior, as per the exhibit and the detailed explanation, is that traffic sent from Server1 will be tagged with VLAN ID 200 when it reaches Server2 via leaf2. This ensures proper traffic segmentation and handling across the VXLAN-enabled data center network.

NEW QUESTION # 51
You are deploying an EVPN-VXLAN overlay. You must ensure that Layer 3 routing happens on the spine devices. In this scenario, which deployment architecture should you use?

A. CRB
B. bridged overlay
C. ERB
D. distributed symmetric routing

Answer: A

Explanation:
* Understanding EVPN-VXLAN Architectures:
* EVPN-VXLAN overlays allow for scalable Layer 2 and Layer 3 services in modern data centers.
* CRB (Centralized Routing and Bridging):In this architecture, the Layer 3 routing is centralized on spine devices, while the leaf devices focus on Layer 2 switching and VXLAN tunneling. This setup is optimal when the goal is to centralize routing for ease of management and to avoid complex routing at the leaf level.
* ERB (Edge Routing and Bridging):This architecture places routing functions on the leaf devices, making it a distributed model where each leaf handles routing for its connected hosts.
* Architecture Choice for Spine Routing:
* Given the requirement to ensure Layer 3 routing happens on the spine devices, theCRB (Centralized Routing and Bridging)architecture is the correct choice. This configuration offloads routing tasks to the spine, centralizing control and potentially simplifying the overall design.
* Explanation:
* With CRB, the spine devices perform all routing between VXLAN segments. Leaf switches handle local switching and VXLAN encapsulation, but routing decisions are centralized at the spine level.
* This model is particularly advantageous in scenarios where centralized management and routing control are desired, reducing the complexity and configuration burden on the leaf switches.
Data Center References:
* The CRB architecture is commonly used in data centers where centralized control and simplified management are key design considerations. It allows the spines to act as the primary routing engines, ensuring that routing is handled in a consistent and scalable manner across the fabric.

NEW QUESTION # 52
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 10006 is 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.
