Understanding Pure IP Fabric:

A pure IP fabric is a network design where all devices operate at Layer 3, meaning that each device in the fabric is a router that makes forwarding decisions based on IP addresses.

Layer 2 Support:

In a pure IP fabric, traditional Layer 2 protocols such as Spanning Tree Protocol (STP) or VLANs are not supported. Instead, the network relies entirely on Layer 3 routing protocols to manage traffic between devices.

Routing Functionality:

Since devices in an IP fabric operate as Layer 3 routers, they handle IP routing and provide network services based on IP addresses, not on MAC addresses or Layer 2 switching.

Conclusion:

Option A:Correct—Devices in an IP fabric function as Layer 3 routers.

Option D:Correct—A pure IP fabric does not support traditional Layer 2 protocols, making it a purely routed environment.

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

Zero Touch Provisioning (ZTP):

Juniper Networks' ZTP (Zero Touch Provisioning) process automates the deployment of new devices by allowing them to fetch and execute scripts for configuration and setup as they are powered on and connected to the network.

Supported Scripting Languages:

The Junos OS supports several scripting languages that can be used during the ZTP process:

Shellscripts are often used for general automation tasks.

Pythonis a widely supported language in Junos, offering powerful scripting capabilities for automating network tasks.

SLAX(Service Logic Execution Environment) is a scripting language specific to Junos, designed to automate configuration tasks and simplify network operations.

Conclusion:

Option D:Correct—Junos ZTP supports Shell, Python, and SLAX, making it the correct choice among the provided options.
