Which core component of MDT describes the data that an MDT-capable device streams to a collector?
The correct answer is A. sensor path. In Model-Driven Telemetry (MDT), the sensor path is the core component that precisely defines the specific operational data streamed from a device to a collector.

Why each option
In Model-Driven Telemetry (MDT), the sensor path is the core component that precisely defines the specific operational data streamed from a device to a collector.
A sensor path, also known as a data path or telemetry path, precisely describes the specific operational data points (e.g., interface counters, CPU utilization) within the device's data model that are to be streamed, thereby defining what data is being sent.
An encoder defines how the data is formatted (e.g., JSON, Google Protobuf), not what specific data content is being streamed.
A transport protocol defines how the data is transmitted (e.g., gRPC, UDP), not what data content is being streamed.
A subscription is the overall configuration that bundles sensor paths, encoders, and transport protocols, but the sensor path itself specifically describes the data.
