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

NEW QUESTION # 12
Exhibit.

Both DC and DC2 ate using EVPN-VXLAN technology deployed using an ERB architecture. A server on the Red VLAN must communicate with a server on the Green VLAN. The Blue VLAN in DC and DC2 needs to be the same VLAN.
Which statement is correct in this scenario?

A. An interconnect is required between the four SRX Series devices; the Blue VLAN must be stretched and a transit VNI must be added for the Red and Green VLANs.
B. The eight spine devices must be configured as border spine devices; a full mush interconnect must exist between all eight spine devices and the Blue VLAN must be stitched together
C. A lean super spine device must be added to DC and DC2; all VLANs must be stretched to the lean super spine device and the lean super spine devices must stitch all the VLANs together.
D. An interconnect is required between four leaf devices in the services blocks; the Red VLAN and the Green VLAN must be stitched and the Blue VLAN must be stretched.

Answer: A

Explanation:
* ERB Architecture in EVPN-VXLAN:
* ERB (Edge Routed Bridging) architecture is commonly used in data center networks where routing decisions are made at the network edge (leaf or border devices), while bridging (Layer 2 forwarding) is extended across the fabric. This architecture allows for efficient L3 routing while still enabling L2 services like VLANs to span across multiple locations.
* VLAN and VNI Configuration:
* The scenario specifies that a server on the Red VLAN needs to communicate with a server on the Green VLAN. Since these VLANs are in different data centers (DC and DC2), and given the use of EVPN-VXLAN, the communication between these VLANs will require atransit VNI(Virtual Network Identifier). This transit VNI will allow traffic to traverse the VXLAN tunnel across the DCI (Data Center Interconnect).
* Interconnect between SRX Series Devices:
* The exhibit shows SRX Series Chassis Clusters used as service devices (likely for firewalling or other security services). These devices need to be interconnected between the two data centers to ensure that VLANs can communicate effectively. The Blue VLAN needs to be stretched between DC and DC2 to maintain the same Layer 2 domain across both data centers.
Conclusion:
* Option B:Correct-Interconnecting the SRX Series devices will ensure the necessary service chaining, while stretching the Blue VLAN and adding a transit VNI for the Red and Green VLANs will enable the required communication across the data centers.

NEW QUESTION # 13
Whatare two supported methods (or exporting data when using the Junos telemetry interface? (Choose two.)

A. using REST
B. using UDP
C. using gRPC
D. using SNMP

Answer: B,C

Explanation:
* Junos Telemetry Interface (JTI):
* The Junos Telemetry Interface is a framework that allows network operators to collect real-time telemetry data from Juniper devices. This data can be used for monitoring, analytics, and network automation.
* Data Export Methods:
* Option B:UDP (User Datagram Protocol)is a lightweight, connectionless protocol used for exporting telemetry data quickly with minimal overhead. While it doesn't guarantee delivery, it is suitable for high-speed data transfer where occasional packet loss is acceptable.
* Option D:gRPC (gRPC Remote Procedure Call)is a modern, high-performance method for data export that supports streaming and remote procedure calls, making it ideal for more complex telemetry data use cases.
Conclusion:
* Option B:Correct-UDP is supported for exporting telemetry data.
* Option D:Correct-gRPC is also supported, offering advanced streaming capabilities

NEW QUESTION # 14
You are asked to interconnect two of your company's data centers across the IP backbone. Both data centers have their own unique IP space and do not require any bridging. In this scenario, which two actions would accomplish this task? (Choose two.)

A. Configure a Type 2 EVPN route for each unique prefix.
B. Configure a Type 5 EVPN route for each unique prefix.
C. Configure peering for EVPN between border leaf nodes in each data center.
D. Configure peering for EVPN between all leaf nodes within each data center.

Answer: B,C

Explanation:
* Interconnecting Data Centers:
* The scenario requires interconnecting two data centers with unique IP spaces across an IP backbone. The key point is that bridging is not required, so Layer 3 routing methods must be used.
* EVPN Configuration:
* Option B:Establishing EVPN peering between the border leaf nodes in each data center is the most appropriate solution as it allows for exchanging routing information between the two data centers. This ensures that the routes are properly distributed without the need for L2 bridging.
* Option C:Configuring Type 5 EVPN routes is necessary for advertising IP prefixes (Layer 3 routes) across the EVPN. Type 5 routes allow for the exchange of IP prefixes between the two data centers, enabling the necessary routing functionality without the need for bridging.
Conclusion:
* Option B:Correct-Peering between border leaf nodes sets up the necessary route exchange between data centers.
* Option C:Correct-Type 5 EVPN routes are essential for exchanging Layer 3 prefixes between data centers.

NEW QUESTION # 15
You are asked to deploy 100 QFX Series devices using ZTP Each OFX5120 requires a different configuration. In this scenario, what are two components that you would configure on the DHCP server?
(Choose two.)

A. the MAC address for each OFX5120
B. the management IP address for each OFX5120
C. the IP address of the FTP server
D. the MAC address of the FTP server

Answer: A,B

Explanation:
* Zero Touch Provisioning (ZTP):
* ZTP allows for the automated configuration of network devices, like QFX Series switches, without manual intervention. During ZTP, a switch will obtain its configuration from a DHCP server and then download the required software and configuration files from a specified server (e.
g., FTP, HTTP).
* DHCP Server Configuration:
* Option B:The DHCP server needs to know theMAC address for each QFX5120to provide a specific configuration based on the device identity. By mapping the MAC address to a particular configuration, the DHCP server can ensure that each switch gets the correct configuration.
* Option D:Themanagement IP address for each QFX5120must also be assigned by the DHCP server. This IP address allows the device to communicate on the network and access the configuration files and other required resources during the ZTP process.
Conclusion:
* Option B:Correct-MAC addresses allow the DHCP server to identify each QFX5120 and assign the appropriate configuration.
* Option D:Correct-Management IP addresses are essential for network communication during ZTP.

NEW QUESTION # 16
You are implementing seamless stitching between two data centers and have a proposedconfiguration for a border leafdevice.
In this scenario, which two statements are correct? {Choose two.)

A. The translation-vni must match in both data centers.
B. The ESI must be different in each data center.
C. The translation-vni must be different in each data center.
D. The ESI must match in both data centers.

Answer: C,D

Explanation:
* Understanding Seamless Stitching:
* Seamless stitching is used in EVPN to interconnect two data centers, allowing for consistent Layer 2 and Layer 3 connectivity across them. This is often achieved by translating VNIs (Virtual Network Identifiers) between the data centers.
* Translation-VNI:
* Option B:The translation VNI must be different in each data center to ensure that traffic can be correctly routed and distinguished as it crosses between the data centers. This differentiation helps to maintain the integrity of the traffic flows and prevents any potential overlap or conflict in VNIs.
* Ethernet Segment Identifier (ESI):
* Option D:The ESI must match in both data centers to ensure that the same Ethernet segment (which could be multihomed) is recognized consistently across the data centers. Matching ESIs are crucial for maintaining a unified view of the Ethernet segment across the interconnected fabric.
Conclusion:
* Option B:Correct-Translation VNIs must be unique to each data center for proper traffic distinction.
* Option D:Correct-Matching ESIs are necessary to maintain consistent Ethernet segment identification across both data centers.
