An engineer is developing a configuration script to enable dial-out telemetry streams using gRPC on...

The configuration in Option A is correct for enabling dial-out telemetry streams using gRPC on devices with TLS disabled.

It uses model-driven telemetry (MDT), which is a new method of monitoring network devices. Unlike traditional methods that pull data from the device, MDT pushes data from the device to the collector.

In this configuration:

Telemetry is model-driven.

It specifies a destination group with an IP address and port number where the telemetry data will be sent.

The encoding is self-describing-gpb (Google Protocol Buffers).

The protocol used is TCP.

This setup ensures that telemetry data is sent to the specified collector without requiring TLS encryption.
