Juniper Data Center, Professional (JNCIP-DC) Sample Questions (Q12-Q17):

NEW QUESTION # 12
You are deploying an IP fabric using EBGP and notice that your leaf devices areadvertising and receiving all the routes. However, the routes are not installed in the routing table and are marked as hidden.
Which two statements describe how to solve the issue? (Choose two.)

A. You need to configure a next-hop self policy.
B. You need to configure loops 2.
C. You need to configure multipath multiple-as.
D. You need to configure as-override.

Answer: A,C

NEW QUESTION # 13
Which three statements are correct about VXLAN control planes? (Choose three.)

A. EVPN is inefficient and does not scale well.
B. Multicast does not require as many resources.
C. Multicast is not agile and requires manual VNI mapping.
D. EVPN enables fast convergence and updates.
E. Both multicast and EVPN can facilitate MAC learning.

Answer: B,D,E

Explanation:
* VXLAN Control Planes:
* VXLAN (Virtual Extensible LAN) uses different control planes to handle MAC learning and traffic forwarding. The control planes include multicast and EVPN (Ethernet VPN).
* Multicast and EVPN Comparison:
* Option B:Both multicast and EVPN can be used for MAC learning in a VXLAN environment.
Multicast is a more traditional approach, while EVPN is more advanced and supports distributed MAC learning.
* Option D:EVPN offers benefits such as fast convergence and rapid updates, making it more efficient and scalable for modern data center environments.
* Option E:Multicast does not require as many resources because it relies on traditional Layer 3 multicast mechanisms to distribute broadcast, unknown unicast, and multicast (BUM) traffic.
However, it can be less flexible and less scalable compared to EVPN.
Conclusion:
* Option B:Correct-Both control planes facilitate MAC learning.
* Option D:Correct-EVPN provides fast convergence and updates.
* Option E:Correct-Multicast is resource-efficient but less flexible.

NEW QUESTION # 14
Exhibit.

You have implemented an EVPN-VXLAN data center. Device served must be able to communicate with device server2.
Referring to the exhibit, which two statements are correct? (Choose two.)

A. Traffic from server! to server2 will transit the VXLAN tunnel between leaf1 and Ieaf2.
B. Traffic from server1 to server2 will transit a VXLAN tunnel to spinel or spine2. then a VXLAN tunnel from spinel or spine2 to Ieaf2.
C. An IRB Interface must be configured on leaf1 and Ieaf2.
D. An IRB interface must be configured on spinel and spine2.

Answer: A,C

Explanation:
* Understanding the Exhibit Setup:
* The network diagram shows an EVPN-VXLAN setup, a common design for modern data centers enabling Layer 2 and Layer 3 services over an IP fabric.
* Leaf1 and Leaf2 are the leaf switches connected to Server1 and Server2, respectively, with each server in a different subnet (172.16.1.0/24 and 172.16.2.0/24).
* Spine1 and Spine2 are part of the IP fabric, interconnecting the leaf switches.
* EVPN-VXLAN Basics:
* EVPN (Ethernet VPN) provides Layer 2 and Layer 3 VPN services using MP-BGP.
* VXLAN (Virtual Extensible LAN) encapsulates Layer 2 frames into Layer 3 packets for transmission across an IP network.
* VTEP (VXLAN Tunnel Endpoint) interfaces on leaf devices handle VXLAN encapsulation and decapsulation.
* Integrated Routing and Bridging (IRB):
* IRB interfaces are required on leaf1 and leaf2 (where the endpoints are directly connected) to route between different subnets (in this case, between 172.16.1.0/24 and 172.16.2.0/24).
* The IRB interfaces provide the necessary L3 gateway functions for inter-subnet communication.
* Traffic Flow Analysis:
* Traffic from Server1 (172.16.1.1) destined for Server2 (172.16.2.1) must traverse from leaf1 to leaf2.
* The traffic will be VXLAN encapsulated on leaf1, sent over the IP fabric, and decapsulated on leaf2.
* Since the communication is between different subnets, the IRB interfaces on leaf1 and leaf2 are crucial for routing the traffic correctly.
* Correct Statements:
* C. An IRB Interface must be configured on leaf1 and leaf2:This is necessary to perform the inter-subnet routing for traffic between Server1 and Server2.
* D. Traffic from server1 to server2 will transit the VXLAN tunnel between leaf1 and leaf2:
This describes the correct VXLAN operation where the traffic is encapsulated by leaf1 and decapsulated by leaf2.
Data Center References:
* In EVPN-VXLAN architectures, the leaf switches often handle both Layer 2 switching and Layer 3 routing via IRB interfaces. This allows for efficient routing within the data center fabric without the need to involve the spine switches for every routing decision.
* The described traffic flow aligns with standard EVPN-VXLAN designs, where direct VXLAN tunnels between leaf switches enable seamless and scalable communication across a data center network.

NEW QUESTION # 15
Exhibit.

Host A is connected to vlan 100 on lead. Host B is connected to vlan 200 on leaf1. Host A and Host B ate unable to communicate. You have reviewed the touting and your hosts have the correct default route (.1) Referring to the exhibit, which two commands will solve the problem? (Choose two.)

A. set routing-options static route 0.0.0.0/0 next-hop 192.168.200.10
B. delete vlans vn200 13-interface irb.200
C. set vlans vn10013-interface irb.100
D. set interfaces irb unit 100 family inet address 192-168.100.1

Answer: A,C

Explanation:
In the provided network configuration, Host A is in VLAN 100 and Host B is in VLAN 200. The issue arises because these two hosts are unable to communicate, which indicates that either the interfaces are not properly linked to their respective VLANs, or there is a missing static route required for inter-VLAN routing.
Step-by-Step Analysis:
* VLAN Assignment:
* The exhibit shows that irb.200 is correctly associated with VLAN 200 in the configuration.
However, there is no corresponding irb.100 for VLAN 100. Without irb.100, the network lacks the logical interface to handle routing for VLAN 100. Thus, adding irb.100 to VLAN 100 is necessary.
Command to solve this:
set vlans vn100 13-interface irb.100
* Static Route Configuration:
* For inter-VLAN routing to occur, a static route needs to be configured that allows traffic to pass between different subnets (in this case, between VLAN 100 and VLAN 200). The command set routing-options static route 0.0.0.0/0 next-hop 192.168.200.10 would add a static route that directs all traffic from VLAN 100 to the correct gateway (192.168.200.10), which is necessary to route traffic between the two VLANs.
Command to solve this:
set routing-options static route 0.0.0.0/0 next-hop 192.168.200.10
Explanation of Incorrect Options:
* Option A (delete vlans vn200 13-interface irb.200): This would remove the logical interface associated with VLAN 200, which is not desired because we need VLAN 200 to remain active and properly routed.
* Option B (set interfaces irb unit 100 family inet address 192-168.100.1): This command would incorrectly assign an IP address that does not correspond with the subnet of VLAN 100 (192.168.200.1
/24). This could create a misconfiguration, leading to routing issues.
Data Center References:
For a Data Center, proper VLAN management and static routing are crucial for ensuring that different network segments can communicate effectively, especially when dealing with separated subnets or zones like in different VLANs. This aligns with best practices in DCIM (Data Center InfrastructureManagement) which stress the importance of proper network configuration to avoid downtime and ensure seamless communication between all critical IT infrastructure components.
Ensuring that the correct interfaces are associated with the correct VLANs and having the proper static routes in place are both essential steps in maintaining a robust and reliable data center network.
This detailed analysis reflects best practices as noted in standard data center design and network configuration guides.

NEW QUESTION # 16
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 ARP lookup for this host has failed.
B. The EVPN route for this host does not have a valid next hop.
C. The host for this entry is locally connected to leaf1.
D. This entry is associated with a multicast EVPN route.

Answer: B

Explanation:
In this scenario, the active source field is blank for the MAC address 00:0c:29:e8:b7:39, indicating an issue with how this MAC entry is being processed within the EVPN/VXLAN environment.
Step-by-Step Analysis:
* Understanding the MAC Entry:
* The active source field should normally indicate the source of the route advertisement for a specific MAC address within the EVPN. If it is blank, it suggests that there is a problem with how this entry is being learned or propagated.
* Possible Issues:
* Option A:If the EVPN route for this MAC address does not have a valid next hop, the entry might exist in the MAC table, but it will not have a valid path for forwarding, leading to a blank active source.
* Option B:If the ARP lookup had failed, the entry might not even appear in the MAC table.
However, the entry does exist, suggesting that ARP is not the primary issue here.
* Option C:If the host were locally connected, the active source should reflect a local interface, but the field is blank, ruling out local connection as the cause.
* Option D:Multicast EVPN routes typically do not appear in this manner in the MAC table, and this would not cause the active source to be blank.
Conclusion:The most logical explanation is that the EVPN route for this host exists but does not have a valid next hop, leading to the absence of an active source. This is consistent with how EVPN routing tables work in a VXLAN environment, where the lack of a valid next hop would prevent proper route advertisement and forwarding for the specific MAC address.
