350-501 Question #420: Real Exam Question with Answer & Explanation

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.

Question

Which core component of MDT describes the data that an MDT-capable device streams to a collector?

Options

Asensor path
Bencoder
Ctransport protocol
Dsubscription

Explanation

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.

Common mistakes.

B. An encoder defines how the data is formatted (e.g., JSON, Google Protobuf), not what specific data content is being streamed.
C. A transport protocol defines how the data is transmitted (e.g., gRPC, UDP), not what data content is being streamed.
D. A subscription is the overall configuration that bundles sensor paths, encoders, and transport protocols, but the sensor path itself specifically describes the data.
