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 datacenters. 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.

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.

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
