Juniper Data Center, Professional (JNCIP-DC) Sample Questions (Q51-Q56):

NEW QUESTION # 51
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) and irb.800 (vlan 800) are able to communicate over the fabric.
  • 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) are not able to communicate directly with devices in routing instance Customer A.

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 # 52
You are asked to automatically provision new Juniper Networks devices in your network with minimal manual intervention Before you begin, which two statements are correct? (Choose two.)

  • A. You must have a system log (syslog) server to manage system log messages and alerts.
  • B. You must have a file server that stores software image and configuration files.
  • C. You must have a DHCP server that provides the location of the software image and configuration files.
  • D. You must have an NTP server to perform time synchronization.

Answer: B,C

Explanation:
* Zero-Touch Provisioning (ZTP):
* ZTP is a feature that allows for the automatic provisioning of devices with minimal manual intervention. It is widely used in large-scale deployments to quickly bring new devices online.
* Key Requirements for ZTP:
* A. DHCP Server:A DHCP server is crucial for ZTP as it provides the necessary information to new devices, such as the IP address, the location of the software image, and configuration files.
* D. File Server:The file server is where the software image and configuration files are stored. The device downloads these files during the provisioning process.
* Incorrect Options:
* B. Syslog Server:While a syslog server is important for logging and monitoring, it is not a requirement for the initial provisioning process.
* C. NTP Server:An NTP server is used for time synchronization, which is essential for accurate logging and operation but not specifically required for ZTP.
Data Center References:
* ZTP simplifies the deployment process by automating the initial configuration steps, relying heavily on DHCP for communication and a file server for delivering the necessary configuration and software.


NEW QUESTION # 53
Exhibit.

You want to enable the border leaf device to send Type 5 routes of local networks to the border leaf device in another data center. What must be changed to the configuration shown in the exhibit to satisfy this requirement?

  • A. Add encapsulation vxlan to the evpn hierarchy.
  • B. Add a VLAN configuration with an 13-interface to the tenant1 routing instance.
  • C. Move vrf-target target: 65000:1 to the evpn hierarchy.
  • D. Change: 5001 in the route-distinguisher to : 10010.

Answer: C

Explanation:
In this scenario, you want the border leaf device to advertise Type 5 EVPN routes to another border leaf in a different data center. Type 5 routes in EVPN are used to advertise IP prefixes, which means that for proper route advertisement, you need to configure the correct settings within the evpn hierarchy.
Step-by-Step Analysis:
* Understanding EVPN Type 5 Routes:
* EVPN Type 5 routes are used to advertise IP prefixes across EVPN instances, which allow different data centers or networks to exchange routing information effectively.
* VRF Target Setting:
* The vrf-target configuration is crucial because it defines the export and import policies for the VRF within the EVPN instance. For EVPN Type 5 routes to be advertised to other border leaf devices, the vrf-target needs to be correctly configured under the evpn hierarchy, not just within the routing instance.
Command to solve this:
move vrf-target target:65000:1 to evpn
* Other Options:
* Option B:Adding a VLAN configuration would not address the requirement to advertise Type 5 routes.
* Option C:Adding VXLAN encapsulation may be necessary for other scenarios but does not directly address the Type 5 route advertisement.
* Option D:Changing the route-distinguisher will differentiate routes but does not impact the advertisement of Type 5 routes to other data centers.
By moving the vrf-target to the evpn hierarchy, you enable the proper route advertisement, ensuring that the Type 5 routes for local networks are shared with other data center border leaf devices. This is aligned with best practices for multi-data center EVPN implementations, which emphasize the correct placement of routing policies within the EVPN configuration.


NEW QUESTION # 54
Which two statements are correct about an IP fabric? (Choose two.)

  • A. All leaf devices can use the same AS number in an IP fabric without making any adjustments to the EBGP configuration
  • B. FBGP is only required to route mostrouting information to external devices outside the fabric.
  • C. Only a single point to point EBGP session is required between peers in an IP fabric.
  • D. The multipath multiple-as statement is required to enable ECMP if every device has a different AS number.

Answer: A,D

Explanation:
* BGP in IP Fabric:
* In an IP fabric, Border Gateway Protocol (BGP) is used to manage the routing between leaf and spine devices. Each device can have the same or different Autonomous System (AS) numbers depending on the network design.
* Multipath Multiple-AS:
* Option B:If every device in the fabric has a different AS number, then enabling Equal-Cost Multi-Path (ECMP) routing requires the multipath multiple-as statement. This configuration allows BGP to consider multiple paths across different AS numbers as equal cost, enabling efficient load balancing across the network.
* Same AS Number Configuration:
* Option A:It's possible for all leaf devices to use the same AS number in an IP fabric, which simplifies the configuration. EBGP (External BGP) will still function correctly in this setup because BGP considers the peering relationship rather than strictly enforcing different AS numbers in this specific use case.
Conclusion:
* Option B:Correct-This statement is essential for enabling ECMP in a multi-AS environment.
* Option A:Correct-Leaf devices can share the same AS number without needing special EBGP configuration.


NEW QUESTION # 55
Whatare two ways in which an EVPN-signaled VXLAN is different from a multicast-signaled VXLAN?
(Choose two.)

  • A. An EVPN-signaled VXLAN can perform autodiscovery of VTEPs using BGP.
  • B. An EVPN-signaled VXLAN features slower and more complete convergence.
  • C. An EVPN-signaled VXLAN can perform autodiscovery of VTEPs using IS-IS.
  • D. An EVPN-signaled VXLAN is less resource intensive.

Answer: A,D

Explanation:
* Multicast-Signaled VXLAN:
* In traditional multicast-signaled VXLAN, VTEPs (VXLAN Tunnel Endpoints) use multicast to flood and learn about remote VTEPs. This method relies on multicast in the underlay network to distribute BUM (Broadcast, Unknown unicast, and Multicast) traffic.
* This approach can be resource-intensive due to the need for multicast group management and increased network traffic, especially in large deployments.
* EVPN-Signaled VXLAN:
* EVPN-signaled VXLAN uses BGP (Border Gateway Protocol) to signal the presence of VTEPs and distribute MAC address information. BGP is used for VTEP autodiscovery and the distribution of endpoint information.
* This method is more efficient because it reduces the reliance on multicast, instead using BGP control-plane signaling to handle VTEP discovery and MAC learning, which reduces the overhead on the network and improves scalability.
* Correct Statements:
* B. An EVPN-signaled VXLAN can perform autodiscovery of VTEPs using BGP:This is correct because EVPN uses BGP for VTEP autodiscovery, making it more efficient and scalable compared to multicast-based methods.
* C. An EVPN-signaled VXLAN is less resource-intensive:This is correct because it eliminates the need for multicast flooding in the underlay, instead using BGP for signaling, which is less demanding on network resources.
* Incorrect Statements:
* A. An EVPN-signaled VXLAN can perform autodiscovery of VTEPs using IS-IS:This is incorrect because EVPN relies on BGP, not IS-IS, for VTEP discovery and signaling.
* D. An EVPN-signaled VXLAN features slower and more complete convergence:This is incorrect; EVPN with BGP typically provides faster convergence due to its use of a control plane rather than relying on data plane learning.
Data Center References:
* EVPN-VXLAN is widely adopted in modern data center designs due to its scalability, efficiency, and reduced resource consumption compared to multicast-based VXLAN solutions. It leverages the strengths of BGP for control-plane-driven operations, resulting in more efficient and scalable networks.
